Following success in Chad to solve sand production issues in water injection wells, Tendeka is working with a local partner in Nigeria to deliver Casacde3 in a multi-well subsea development.
Environment Quality Services (EQS) has successfully assisted in a decommissioning project offshore Angola. Dubai-based EQS deployed their Saab Seaeye Falcon to assess the integrity of the offshore structures via visual inspection and image gathering.
Carlos Rodrigues, CTO, of EQS, commented, The Falcon supports EQS in their aim to fulfil specific works in a safe and cost-effective manner by delivering accurate and relevant information.”
Rodrigues said that the Falcon is an ideal resource for specialist work as it can handle an array of cameras, sensors, tooling and complex data gathering systems that can easily be added or changed thanks to the Falcon iCON intelligent module- focused distributed control architecture.
The Falcon is the top selling robot of its class and its success is attributed to it being a portable, metre-sized, intelligent, powerful highly mahneuverable, easy-to-use vehicle with a depth rated range to 1,000 metres.
It has a reliability record covering more than one million hours underwater, including deep tunnel work. The Falcon can remain stable in turbulent waters and strong currents whilst undertaking both robust and precision tasks.
The structures inspected on the platform offshore Angola included the platform (jacket), well head, protection dome, pipelines and umbilical. EQS helped the offshore energy clients navigate the complex environmental regulatory landscape to achieve compliance as well.
Presenting at the Offshore Well Intervention West Africa 2021 virtual conference, Bhargava Ram Gundemoni, 3M Global Solutions Specialist, explained how better sand control can lead to better productivity and profitability.
Traditional practices used for the sand control selection (SCS) process are based on mature technologies and methodologies that fail to meet the key performance drivers. The metallic filter media has erosion limits that constrict the boundary condition of the traditional SCS practices which result in failing to meet the asset productivity demand and the performance drivers not being achieved in many cases.
An alternative to the traditional sand control approach
The solution is a change of metallic filter media to ceramic filter media of the screen. 3M’s solution is 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 held 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. The ceramic material at the inflow offers higher erosion resistance, therefore mitigating hotspotting potential. This allows the operator a wider operating window of productivity.
Erosion constraint on the metallic filter media limits the well operating limits, limiting the productivity potential and the application envelope of applying a standalone screen system.
Using a ceramic filter media operators have proven in green fields and brown fields to shift the boundary conditions of applying stand-alone screens as demonstrated in the below picture, and achieved reduced risk to erosion failure and increase productivity. 3M Ceramic Sand Screens offers operational simplicity, reduced HSE risk to unlock production potential with faster return on investment by enabling standalone screen deployment as a simple sand control tool to address in a wider range of reservoir conditions
Standardised field-wide approach
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.
To emphasis the effectiveness of the solution Ram presented three case studies from different regions across the globe.
Remedial sand control in a subsea re-perforated well intervention vessel in the North Sea
Customer challenge: The oil well was not operational due to depletion with a gas cap identified shallower to main zone. The operator intended to cost-effectively exploit the gas cap using rigless deployment method to add additional revenue from the existing asset. The project also needed to run a stand-alone sand screen in the open sea and through a subsea lubricator and required sub-sea well (deviated) intervention in harsh deployment conditions. The well downhole environment was extremely erosional and a reliable, robust solution was required to prevent failure at a reasonable cost.
Solution: The operator opted for ceramic sand screen deployment on a light well intervention vessel and run the screen through an e-line wireline system with an expandable packer system through open sea into the sub-sea lubricator.
Results and value creation: The operator was able to achieve production rates of 45 MMSCFD of gas sand-free through the solution. The 3M ceramic sand screen for this project was deployed successfully in April 2016 and was replicated in other wells with the same scope of work.
Marginal gas fields in Indonesia with ceramic sand screens
Customer challenge: The operator had to deal with marginal reserves with stacked reservoirs and was a low-cost environment. High flux velocity expected at sand face due to shallow and low-pressure, short intervals and needed robust and rigless deployable solution to achieve economical sense with heterogenous sand properties being a challenge.
Solution: High erosion and hot spotting resistant ceramic screens enable the operator to set across the perforation zone which are deployed on slickline with one or two pup joints depending on the perforation length.
Value creation: The operator achieved cost savings of up to 70% compared to the previous sand control approach and was able to increase reservoir deliverability by more than 200% of the average cumulative gas produced. The operator can now complete more zones per year and achieving a sand-free higher cumulative production volume, extending as a standardised approach to multiple assets as a primary sand control method.
Ceramic sand screens in high rate oil wells in Azerbaijan
Customer challenge: The operator had no sand control in place. With reservoir maturing and downhole conditions changed over time, sand production increased to a level where production targets are not achieved leading to well shut-in to integrate downhole sand control. Key challenges in selection of sand control are achieving cost-effective sand control approach without needing a rig in well conditions of high Fines, poorly distributed reservoir sand PSD with fluid flow at high flux and impingement velocity
Solution: 3M ceramic sand screens length of 203 ft, were set across 9 ⅝ inch casing perforation using coil tubing deployment method.
Value creation: The operator achieved ROI within five days based on the current oil price and was able to clock a sand-free production rate of 8000 BOPD and 46 MMSCFD gas. The operator also recorded a production gain of 2500 BOPD sand-free. Significant improvement on the PI over time exceeding the expectation of a standalone screen in such reservoir sand distribution with a low cost of deployment at reduced carbon footprint installing sand control mitigating need of a rig.
Solutions to maximise profitability
As of Oct 31 2021, 3M has completed 125 installations for sand control with users consisting of 50% oil producers and 50% gas producers. For general intervention applications 3M has maintained a manufacturing time of 6-12 weeks with variables such as size, quantity and shipping time to location.
3M remarked that the solution can help operators meet future energy policies to reduce carbon intensity for deployment with rigless approach where feasible and reduce the sand control future repairs offering a robust solution. The simple stand-alone screen and faster deployment means reducing HSE, operational risk and mean time between failures.
3M added, “There are a lot of wells globally where operators can unlock production potential from their shut-in wells due to failed primary sand control or from thin-bed reservoirs or reservoirs which have not been exploited because they are deemed un-economic and left behind the casing. 3M’s ceramic sand-screens enables an operator to approach such cases using a rig-less method, without the removal of tubing and requirement of a complex rig sand control solution. 3M has proven this at multiple fields and assets globally.”
With a field track record of 125 successful application, operators in West Africa can find proven results from similar conditions to their reservoirs as reference case study.

Riserless Light Well Intervention (RLWI) is proving to be a cost-effective method of intervening in West Africa’s offshore wells, using suitable support vessels instead of rigs.
A panel of industry experts came together at the Offshore Well Intervention West Africa 2021 conference to discuss the risks posed by RLWI and how the industry is perceiving new technologies driving the uptake of such activities.
Chiwuike Amaechi, Principal Subsea Intervention Engineer of SNEPCo, said that value realisation is one of the key risks that need to be considered when picking an intervention method. “Categories for this include production enhancement and well integrity. The economic threats are mainly around the fears of obtaining the projected production gains which would justify the investment into the intervention,” he added.
Elaborating on the challenges related to environmental safety, he said it is difficult to clean out a well in a purely riserless intervention. “How do you ensure that you do not release any hydrocarbons to the environment, particularly in places where there are strict regulatory requirements and organisations that have a zero spill policy? These are some of the roadblocks that we face in the implementation of riserless interventions,” Chiwuike said.
Oladapo Ajayi, Division Geounit Manager of Reservoir Performance in Nigeria and West Africa, Schlumberger, also gave his insights on the topic from a well service company’s perspective. He said they usually look at factors like water depth, climate and most importantly, the commercial aspect. “There’s always the triple constraint – time, cost and quality of the performance. In terms of time, the schedule and planning are important and when we say cost, we mean the budget we are looking at.”
According to Andrea Sbordone, Business Development Manager for TIOS, the risk associated with RLWI does not increase alongside depth. “We see RLWI as a better option from an environmental perspective, as the impact is significantly lower and the number of people needed is less too,” he said, adding that operators who have not used RLWI before have now become much more comfortable after using it once.
Moderator Thomas Angell, Director of Offshore Network, said that the idea of ‘horses for courses’ might have changed in the last 5 to 10 years in the intervention field, and Sbordone opined that flexibility is important, and one should be prepared for surprises. “In the last 15 years, the kind of operations you can do on e-line have been increasing, the gap (with coiled tubing) is reducing slowly.” Agreeing with his co-panelist, Oladapo Ajayi said that indeed the gap has reduced in comparison to previous years.
As new technologies have entered the market, the panelists stressed the idea that these need to be properly tested before they can be utilised. “We do need to see technologies matured somewhere else. It is always good to have seen it work beforehand and find out the success rate as well as what failed for learning,” informed Chiwuike.
Sbordone noted that, in terms of downhole solutions, new technology is released every year which is deployable from a riserless light well intervention vessel such as sealing technologies for example. In terms of conveyance he added there has been big steps taken forward and riserless coil tubing solutions, for instance, are making significant progress to be field-proven.
“Last year, we did a campaign of riserless coiled tubing coring in Norway, in water depths up to 3085 m. We deployed riserless coil tubing 14 times. This confirms that water depth is not an issue for riserless coil tubing. Times are changing and people are becoming more adaptable to new technologies.
“15 years ago, if you asked a coil tubing provider to put coil tubing through open water as a pumping downline in 2,000 m, they would be apprehensive to agree. However, slowly the industry started doing it and now it is pretty much the standard,” he added. There has not been a change in the technology used, what has changed is its acceptance and the operators’ confidence in using it.
Stressing on the need for true competency and integration for achieving efficiency, Sbordone said crew integration is important. “This integration is not just for equipment but also for people. The crew working on different parts of the operation should know each other’s work and coordinate the activities to achieve high efficiency.” Chiwuike agreed, highlighting there are significant benefits in efficiency and cost that service providers have been able to bring by offering an integrated solution with vessels that incorporate a complete light well intervention package executed by a core crew that have developed experience through various campaigns.
He added the appetite for RLWI is increasing in West Africa, noting that there were three RLWI campaigns ongoing in West Africa in 2019 in three different countries for three different operators, with three different suppliers. “We believe intervention activity is increasing and will continue to do so.”
Oladapo Ajayi said, “Light intervention is the way, in terms of the efficiency that we gain. There is a full appetite for this kind of work and, for me, technology is the main thing to drive this. Digital can open a new horizon of growth in offshore intervention business and help identify candidate wells, provide a complete portfolio of intervention options to select the optimum solution as well as being able to ensure a predicable successful outcome.”
“The advancement in the digital space provides opportunities for the ability to better risk assess operations and, therefore, make calls on probability of success during the planning stages. Thus, more digital operations ahead of time can be utilised to better improve efficiency of the actual operations. In addition, better planning and utilisation of assets should result in cost reduction. All of this is only possible based upon information sharing between operators and service providers being the key,” he continued.
Angell concluded, “There is now a real understanding of the difference between cost and price and value. These are three things we understand really well known when it comes to complex well programmes.
“The providers out there are the right ones to make this a reality. It would be great to return next year for this conference and listen to some of the projects that everyone has done in that window.”
