For the 7th edition of the Offshore Well Intervention Conference Gulf of Mexico, focus is turning to well intervention optimisation through innovative technologies in order to build a best-in-class workover strategy that suits the changing market.

Bhargava Ram Gundemoni, Global Solutions Specialist at 3M, presented at the OWI GOM virtual webinar in the lead up to the conference and revealed how his company’s innovative solution, the Ceramic Sand Control system, can allow operators to enhance their oil and gas production and increase productivity and profitability, ensuring a reasonable balance between OPEX and EOR to create value and yield.

Ram showcased field proven Ceramic Sand Screens technology with three case studies, revealing how different operators achieved a simplified sand control and the general key performance drivers in sand control selection by reducing equipment and personnel footprint, risk reduction to enhance safety and durability and finally, operational excellence - for increased productivity and increased return on investments.

Challenges and current market needs

The general market needs are to increase productivity for less cost and achieve less risk. Traditional practices used for the Sand Control Selection (SCS) process are based on mature technologies and methodologies that often fail to meet the key performance drivers. Mature technologies often rely on a metallic filter media which is used as the mechanical sand control barrier downhole. Metallics filter media metrologically has erosion limits that constrict the boundary condition of hydrocarbon productivity. If a more erosion resistant filter material can be utilised, the upper safe operational window can be extended limiting the risk of erosional failure and hot spotting of the downhole sand control system whilst optimising asset recovery where possible. In addition, offering greater longevity to downhole sand control through a material change reduces the reported millions of dollars companies employ in repairing wells with failed sand control.

Disrupting the traditional sand control approach

The solution is a change of metallic filter media to ceramic filter media of the screen. This has been achieved by integrating a full-body ceramic part in the form of rings on a pre-perforated base pipe on to which ceramic rings are stacked and hold with two end caps and with an external shroud on top. The stack of ceramic rings creates a slot opening which is designed for the application spec-in and the ceramic material at the inflow offers erosion resistance and therefore mitigating the hotspotting potential ‒ allowing the operator a wider operating window of productivity.

Ceramic Sand Screens have been proved by deployment in the industry both in green fields and in intervention wells, delivering operators operational simplicity, Reduced HSE Risk at lower Capex delivering higher productivity. In some cases, Ceramic Sand Screens has been an enabling technology to unlock production potential with faster return on investments.

Standardised field-wide approach with simplified stand-alone screen sand control

Ceramic Sand Screens unlocks the operator methodology to achieve a simplified and standardised sand control approach in wide range of reservoir conditions and well architecture as downhole sand control system in OH, cased hole on a rig or through tubing rigless applications. Ceramic Sand Screens have been deployed and delivered success in 120+ applications with homogenous, heterogeneous, well-sorted to poorly sorted, low to high fines reservoir of sand properties.

Ceramic Sand Screens are being utilised as an asset wide standard solution to stop proppant flow back in a stimulated well completion.

To learn more about this solution and the advantages it can offer for operators, Offshore Network sat down for an in-depth chat with Ram:

How does ceramic sand screen add value to hydraulic stimulated wells?
“In a hydraulic frac stimulated well completion method, proppant flow back is a challenge. If this is not controlled results in erosion of tubulars, Health Safety and Environment (HSE) issues to potential leak eventually leading to spills. Operators also face economical losses due to prolonged clean up phase post stimulation (additional rig cost due to stand-by) and increased erosion risk to the well jewellery during clean-up. The Ceramic Sand Screens offer an economical approach to dealing with proppant flowback either using rig or rigless deployment methodology.”

“We are offering the opportunity to deal with proppant mitigating the need of resin-coated gravel and in some instances need of gravel packing in stimulated wells. With our solution, the operator has flexibility to use a rigless approach to stimulate/ frac the required zone and then run ceramic sand screens on wireline/ slickline to set across the stimulated zone. The ceramic material is extremely hard in nature offering high resistance to hotspotting and erosion caused by high strength proppant material. This will protect against proppant production topside and restrict equipment from being damaged higher up. In addition to cost-saving and HSE benefits, much less energy is required for deployment, which means the operator leaves less of a carbon footprint by reducing the need of rig."

How this technology can be further utilised in conventional sand control applications by operators to gain value and unlock production potential from their existing standard well stock?
“Not only in stimulated wells, but ceramic sand screens have also extended the traditional operational envelope of ‘Stand-a-Alone’ screen application, proven in unconsolidated sandstone formation. This technology has enabled operators to unlock production potential utilisng less complex rigless deployment technique. There are many wells globally shut-in due to traditional primary sand control failures. Many thin bed reservoirs which are left behind the casing are uneconomic using a rig-based approach. Simplified Sand control methodology with Ceramic Screens can add additional cumulative hydrocarbon production from the existing well stock via an economic satisfied solution.”

Focusing on the upcoming OWI GOM conference, could you explain what operators in USA can take away from this technology to add value to their oil and gas producer fields in Gulf of Mexico?
“In the Gulf of Mexico, operators can adapt their approach with this enabling proven technology to add incremental value to their assets. This approach fits in nicely with the energy trends in the industry, especially in particular the industry thirst in looking at more effective way to address the challenges of ensuring operational excellence. Our solution is simple, flexible, can be implemented rig or rigless and can still yield high productivity proven globally.”

As of 29 September 2021, 3M has completed 121 installations for sand control with users globally consisting of 50% oil producers and 50% gas producers. The product also been qualified in alignment to ISO 17824 / API 19SS Standards.

To best meet customer needs, you must be a solution provider, not just a product provider. Parker LORD’s attitude is, and has always been, to collaborate with customers to find an approach that meets their needs quickly and easily.

They have proven this mindset yet again by finding a better process for working with customers on gimbal assembly design.

Parker LORD gimbal pads and assemblies for offshore oil rigs and intervention vessels are designed under strict process and quality controls to ensure each part performs consistently. They can accurately and dynamically model the stiffness of any gimbal system in any plane of rotation. A step beyond competitors, this new tool incorporates feedback from customers in real time to create tailored solutions. The result is a product designed to handle extreme loading and environmental conditions for improved pad life.

The flexible design tool introduces a process unprecedented for the oil and gas industry, creating solutions through working closely with the customer, instead of only using existing catalog parts. Traditionally, the customer and supplier might have limited interaction during the ordering process. Using this flexible design tool, placing an order becomes a collaborative partnership where Parker LORD engineers and the customer work together to solve problems. Additionally, the tool can accommodate design changes dynamically, allowing for multiple design versions.

To make this work, the first things Parker LORD want to know about a customer’s gimbal assembly is how it is intended to be used, the range of expected limitations and the maximum stiffness needed. From there they work together to produce a solution.

In one example, this fast-moving live design process allowed them to identify, analyse and quote four different systems as the project scope changed over a three-week period. The customer was struggling with how to add a much-needed gimbal assembly to an existing bid and through these conversations they created a solution that was within budget.

The design tool allows system level rotational stiffness calculations in any direction. This graph below shows the relative pad positions and corresponding system rotational stiffness in each plane from center. Asymmetric, or non-uniform spacing can also be evaluated using this tool. 

It takes innovation to work on a solution. Sometimes the solutions can involve renting a part instead of buying it or designing a part to specifications that will then bring it into budget. The market collapse is forcing rig and vessel operators to think differently. Flexibility and elegance around the design are now key.

Fill out this form and a member of Parker LORD’s engineering team will contact you to talk through how their flexible design tool can help you when ordering your next gimbal assembly.

Jonathan Owens, Director Oil and Gas Division, Parker LORD, explains why oil and gas companies are turning to well intervention to maintain production levels and the new technologies entering the market to facilitate this.

With thousands of subsea wells around the world, the task of staying efficient remains challenging. Using deepwater well intervention systems, oil and gas companies can obtain higher profits from under-performing wells, a needed option with today’s oil price fluctuations and profit-focused environment. The COVID-19 pandemic and the resultant decreased demand has brought extra challenges to develop methods to keep wells as efficient as possible, while minimizing capital investment.

Many wells are 20–30 years old and are operating at decreased production rates. To keep maintenance costs in check, operators are turning to well intervention to extend the productive life of aging wells and to repair damaged or underperforming wells.

New systems continue to be developed to keep the industry operating with increased efficiency.

Quick Design Gimbal Assemblies

Gimbal pads and assemblies, located beneath the spider on offshore rigs, provide the necessary compliance between the riser system and vessel to protect drilling equipment from excessive stress and fatigue damage. Parker LORD gimbal pads are designed under strict process and quality controls to ensure each part performs consistently. The resulting product is designed to handle extreme loading and environmental conditions for improved pad life.

An innovative and flexible design tool is available that can quickly generate a new bespoke gimbal assembly design. This tool calculates the system level performance of the gimbal in real time with regards to stiffness, weight, size, and can even tailor stiffness in certain directions. Using this tool, a new design can be produced in just minutes or hours to meet customer needs. Previously it could take weeks to months to produce a design. This process is a dramatic step-change versus what has traditionally been available to the offshore industry – creating customizable gimbal solutions rather than just offering standard products that might not adequately solve the problem.

To make this work, it is important to know how a customer’s gimbal assembly is used, what the limitations are, and the maximum stiffness needed. From there, while working collaboratively with the customer and their constraints, the flexible design tool can outline a solution and identify system trade-offs early in the design process.

As an example, this fast-moving live design process allowed for rapid identification, analysis and quoting on four or five different gimbal systems for a customer as the scope continuously changed over a period of three weeks. The customer was struggling with how to afford the gimbal assembly and through these conversations a solution could be created that was within budget in addition to meeting their technical requirements.

Intervention System Flexible Joints

An important option when maintaining a deepwater well is to use an intervention system flexible joint. It is a softer, more flexible stiffness transition versus the traditional tapered stress joints. In deepwater operations, a flexible joint allows a lower bending moment at the wellhead, so it works well in rougher weather and more dynamic sea states.

To use an intervention system flexible joint with an existing riser system, simply bolt the mating flange on and it will attach to the existing system. The flexible joint provides pressure containment redundancy with a separate seal bearing and load bearing. It improves reliability over a single-bearing design. The seal bearing is optimized for high-pressure containment and fluid resistance. An integrated pressure transducer provides a full-time condition-monitoring system that provides an alert when the first barrier is damaged so appropriate actions can be taken. This failsafe is unavailable on a stress joint or a conventional flexible joint.

In the event of a drive-off or drift-off scenario, a flexible joint in the riser system allows the vessel a wider range of motion without excessive bending of the riser. A flexible joint allows for the critical unlatching at the wellhead even at 10 degrees offset.

Our approach to intervention riser flexible joints has been field proven in basins including Brazil, the North Sea, and West Africa. Over the past four years, Helix Energy Solutions has adopted our intervention system flexible joints on a number of vessels, including the Q7000, the Siem II and the Well Enhancer.

With our product well established in the deepwater intervention space, we have recently found a new application in the newly emerging deepwater mining sector. Working closely with a new customer, we have made slight modifications to the existing flexible joint design to accommodate the requirements of DNVGL RP0034 (Steel Forgings for Subsea Applications - Technical Requirements) and are actively working towards the delivery of our next two flex joints for a subsea mining application slated for 2022.

As the economy continues to struggle, it’s necessary to look to intervention systems to make deep water wells more efficient and productive.

The Parker LORD Noise, Vibration and Harshness Division of Parker Hannifin Corporation, the global leader in motion and control technologies, has developed a proprietary flexible design tool that quickly and easily provides new gimbal assembly designs for offshore oil rigs and intervention vessels.

Parker LORD gimbal pads and assemblies are designed under strict process and quality controls to ensure each part performs consistently. Parker LORD engineers can accurately and dynamically model the stiffness of any gimbal system in any plane of rotation. Using the new flexible design tool, they can now provide a new gimbal assembly design – specifically for the customer’s needs – in minutes or hours instead of the weeks or months previously required.

“We provide innovative solutions by listening to our customers and leveraging nearly a century of experience,” said Scott Reinbold, Lead Engineer, Parker LORD and Designer of the tool. “Our ability to customize offshore oilfield solutions using new tools and capabilities raises the bar and changes expectations. Previously, it was unheard of to be able to make changes on the fly. With this new tool we can collaborate with customers and update designs in real time to adapt to changing project parameters.”

The flexible design tool introduces a process that is unprecedented for the oil and gas industry, creating solutions through working closely with the customer, rather than only using existing catalog parts. Traditionally, the customer and supplier might have limited interaction during the ordering process. Using this flexible design tool, placing an order becomes a collaborative partnership where Parker LORD engineers and the customer work together to solve problems. Additionally, the tool can accommodate design changes dynamically, allowing for multiple design versions.

The gimbal assembly design process considers all aspects of the part including angles, planes of rotation and elastomer selection. The resulting reduction in design time will help to lower costs, reduce maintenance and increase safety.

Once the design is finalized, Parker LORD can use advanced modeling techniques to predict the gimbal system performance characteristics and provide a safe operating envelope for various angles and loads, enabling the end user to optimize operations offshore.

Maggie Demicco, Manager of Business Development & Product Management at Parker LORD, sat down with Offshore Network to discuss how the company’s flexible joint product line, a solution typically reserved for drilling applications, is bringing value to the well intervention market.

While engineers at Parker LORD have predominantly focused their efforts on drilling applications (with products such as telescopic joint packers which are all certified and fielded on many rigs around the world), Demicco described how the company has ventured into the well intervention market, spearheaded by their flexible joint solution. Demicco stated, “This really came about by accident in some ways. Flexible joints are very common in drilling applications but had not been used in intervention applications.

“This particular unique application has a high pressure rating, higher than most flexible joints used in drilling applications. We also envisioned a solution that was compact as intervention vessels are smaller than drilling rigs and this is why it is helpful to have the flexible joint 2 metres high or less as opposed to say 5 metres or more for a stress joint. In doing so you are able to handle higher pressures with a more compact package in that case."

Demicco also described how, with flexible joints installed at the top, operators impart less of a moment on the entire riser system. Flexible joints accommodate any angular offset, much like a ball joint, so less moment is imparted into vessel structure and riser. This allows for benefits such as being able to operate more on the edge of where you could before with a stress joint, such as further off station or in rougher weather.

So far, Helix has fielded three units of this solution, the first two went into service as early as 2017, the third in 2018, and it is also being utilised in a subsea mining application, to enter service next year.

Unlocking value in challenging environments

While the flexible joint can bring benefits in the form of cost saving and safety benefits HSE, it also opens up new opportunities for operators and service providers which were previously restricted by stress joints.

For instance, Demicco commented, “If you have an intervention vessel or rig doing riser-based interventions in deeper water, say 900 metres or more, you’ve got a longer riser and that inherently is more flexible by being longer. In such applications there is less of a need for flexible joints. But if you are in shallower water like 300 metres or less, the riser is a lot shorter so it is more rigid in nature. If you have a stiffer riser system, you put more stress into the wellhead itself at the bottom and into the vessel at the top. In that case flexible joints can provide a lot more benefit with those shorter, stiffer risers if installed at the top and the bottom.”

Demicco added that the flexible joints are even more beneficial when placed at the top and bottom of a riser. Such an advantage could be incredibly useful in regions such as the North Sea which does not only have shallower waters but also rougher sea conditions and a lot of very old wellheads which have undergone multiple interventions over the years. Demicco noted, “Having a flexible joint here would help reduce the stress when you’ve got older wellheads you don’t want to replace, ensuring the field will keep producing.”

While companies such have Helix have not yet incorporated this, Parker LORD sees this as the next step which could provide even more flexibility to potentially expand operation limits even further.

Safety first

At Parker LORD, HSE is considered paramount and reducing risk is inherent in the solutions they offer, as is the case in the flexible joint.

Demicco noted, “One feature of our flexible joint is that it has two separate flexible elements, based on the different way we approach flexible joint design. One flexible element is doing the work of a seal bearing, sealing against intervention fluids. The other one is designed to handle the riser loads and the bending moments. However, while each is designed to do its primary function, if something was to happen, and a seal bearing were to fail, you have the load bearing as a secondary sealing mechanism.

“There is also a sensor between the two barriers to measure the pressure in the cavity which should read as zero in normal operations. If the pressure increases in that cavity, it the sensor will alert you if a failure has happened in the seal bearing, and then you can change it out when you have a convenient opportunity in operations. We consider that a dual barrier, a belt and suspender approach.”

Other solutions on offer

Also on the menu for well intervention operations are Parker LORD’s customisable Gimbal Bearing Assemblies, which, as Demicco outlined, have a similar story in that they were in use on drilling rigs. These are used while running a riser, below the spider and accommodate the vessel motion and support the load of the riser along with whatever equipment is connected.

Demicco said, “If you want to have a Gimbal on an intervention vessel you are often constrained on space so you can’t use an extremely large and stiff 72 inch 1.8 metres wide Gimbal in that case. This is another story where we took a product successful in drilling applications and modified it for an intervention application. Whether more space constrained, required lower stiffness, or the angles are different from drilling application, our engineer from that product line came up with ingenious design tool to take customer inputs for each application and quickly revise the equipment to adjust the parameters on the fly with for the customer.”

Opportunity on the horizon

Demicco added that the company is continuing to explore solutions across the sector, including within the well intervention space. She said, “We know how to design elastomer parts and mitigate shock and vibration. We are talking to customers to find out what their big issues are in those spaces and we typically try and target the problems other people can’t solve, have failed to solve, or unwilling to solve for whatever reason. When we talk to customers about their problems we are asking: Is there some elastomer product that’s failing too quickly and you want to extend the life or are you trying to solve a problem in a non-elastomer way? Is there some other solution we can design using elastomer to solve the problem?"

In regards to the flexible joint, Demicco added that the next step is to get this more widespread, as the hard work has been done. “We have set up this market-based product and the big initial step and cost (getting the mould to manufacture the moulded flexible elements) has been taken. We’ve got that and once we’ve validated that design to the API standard, established our manufacturing processes, that’s really the most important thing. After that it is easier to modify and package those flexible elements differently depending on the customer application. We have the mould, have capacity on the equipment, now just a matter of finding people willing to adopt it and working with them to make modest tweaks to suit their application.”

Maggie Demicco handles Product Management and Business Development for the Oil & Gas business unit of Parker LORD. She holds a B.S. in Mechanical Engineering from Brown University and a Master of Business Administration degree from Babson College.

Tracerco, part of Johnson Matthey Plc, will provide asset integrity data for an operator in the Gulf of Mexico (GOM) to extend the life of over 18 risers.

Tracerco will deploy Discovery, a subsea computed tomography (CT) scanner designed for external scanning of pipelines and which operates along the same general principles as CT scanners used in hospitals.

With environmental concerns posing question marks over continued drilling in the longer term, many operators are keen to ensure that their fields are capable of producing for a much longer period of time, a phenomenon buoyed by new methods of oil and gas extraction allowing them to do so. As such, operators are looking for methods to monitor and verify their risers’ condition to ensure ongoing integrity and extend their operational life.

For life extension, regulators typically require a physical inspection to ensure the condition of the riser and CT, a technique to accurately and non-intrusively see through an item, can provide this information.

Technologies using CT, such as Discovery, provide operators with valuable inspection data on the entire pipeline, spanning the range from product to coating and all areas in between.

It is a non-intrusive external scanning technique and is easily capable of scanning through several inches of pipeline steel with no requirement to remove any protective coating, regardless of thickness and material.

Jim Bramlett, Commercial Manager North America for Tracerco, commented, “Tracerco was the first company to develop a subsea CT system and still holds the fundamental patent for the concept of subsea CT scanning dating back to 2011. Over the years since, Discovery has incorporated numerous additional patented innovations for optimising the system.”

Discovery will be used to inspect the risers and determine whether they can be extended past their original design life by gathering real time data on a variety of integrity issues including pipeline corrosion, pitting and wall thinning. This will allow the operator to work with the local authorities to get their permit extended and potentially realise billions in continued revenues from the asset.

“Discovery provides the integrity insights to know the unknown enabling critical decisions regarding life extension to be made,” added Bramlett. “It does this while the risers are still in full operation. No need to interfere with production.”
