At the Offshore Well Intervention Middle East 2022 conference, Mustafa Adel Amer, Senior Petroleum Production Technology Engineer and Well Integrity Management at BAPETCO, guided the audience through an expert case study focused on well production and methane abatement.
Adel Amer began by explaining the latest goals set out to reduce methane emissions whereby, at COP26, more than 100 countries signed the global methane pledge to cut methane emissions by 30% by 2030. Methane emissions are now at the centre of climate discussions and the abatement of them is, and will become, key to the competiveness of fossil fuels in the future.
The upstream sector, Adel Amer continued, is assumed to contribute around 80% of the methane emissions in the industry, with the majority of this coming from venting operations. Given the global desire to abate methane emissions, it is therefore of paramount importance for operators to reduce this without affecting production rates.
In pursuit of this, Adel Amer presented a case study from his company which focused on treating liquid loaded gas wells in a method that reduced methane emissions and saved significant money.
Adel Amer said, “Liquid loading in a gas well is the inability of produced gas to produce the entrain liquids from the wellbore. Over time, gas velocity decreases and liquids in the well will impact the lift performance that reduce or even stop gas production.”
“Turner discovered the liquid loading could be projected by a droplet model illustrating when droplets move up or down depending on the velocity relative to a critical velocity.”
Adel Amer explained that is common to use VLP to diagnose liquid loading where, in practice, critical velocity is generally defined as the minimum gas velocity in the produced tubing required to produce with low probability of liquid loading risk.
“With the Turner approach, the droplets accumulate in the large ID section but bubble flow takes place at the very low gas flow rate, you need very low gas rate usually at the far left end of the VLP curve. In many cases you don’t see the size of liquid columns that you would expect to balance the drawdown when the well is shut in for cycles.”
Mustafa, in his presentation, presented technical analysis showed that wells that operate in their unstable, hydrostatic dominated, part of their VLP suffer from increased liquid holdup along the entire well.
“We therefore need to focus on increasing velocity across the entire well,” Adel Amer remarked.
In order to do so BAPETCO showed a solution performed on an old well located in an onshore gas field with over 10 wells suffering from liquid loading and run under manual unloading cycles. The well chosen was an old one, beyond 17 years of operation, which had a five inch completion. The task was to end the cyclic behaviour of wells to increase production and eliminate methane emissions.
Considering the context of the field and the company in terms of near wellbore damage after well killing and the well integrity manual that mandate having operable sub-surface safety value in all gas wells, the best solution as Adel Amer said, “was to run a velocity string without killing the well while maintaining the sub-surface safety valve operable and without reliance on a snubbing unit.”
They began by conducting surveillance to select the best candidate wells through in-house developed python code that analyse reservoir data, production data, well history, and well integrity history to gain insightful analytics of the well integrity failure history, potential gain, clearance of the well etc. They then selected candidates and examined the potential in terms of possibility of success and expected gain.
Once done, they went to the PIPESIM to model the surface network and make sure production gains coming from fixing the intermittency of the gas wells would not be constrained by network capacity or connection with other high pressure wells in the network.
The modelling results indicated that inserting 2 7/8 inch completions reduced the risk of liquid loading over the completion string and maintained liquid loading velocity ration favorable for stable gas production.
In practice, to run the velocity string without killing the well, without snubbing units and while having operable sub-surface safety valve, the operating included:
• Rigless inspection of the existing five inch completion and settling an isolation packer with surge disk.
• Workover to run the 2 7/8 inch and set an upper packer below the sub-surface safety valve.
• Rigless coiled tubing to unload the brine and break the surge disk.
Adel Amer said, “This was completed successfully and the project converted the well from one with a fluctuation intermittent behaviour to a more stable state. The stability of production increased to 2.5MMSCF/D after applying the velocity string, up from a 1.5MMSCF/D the day before the project.”
The project helps to achieve various positive results including:
• Cost reduction: the cost of using workover rig to run the 2 7/8 inch tubing inside the existing 5 inch completion was only 10% of a snubbing unit with payback time of 5-6 weeks.
• Increased the gas production rate by 1.5 times and condensate production by 3.8 times.
• The monthly reduced GHG emissions per well is equivalent to 4.4mn miles of passenger vehicle emissions.
• Reduced workload on production operations from elimination of manual unloading.
• Maintained compliance with well integrity standards.
Abel Amer concluded, “We now have a new way of dealing with intermittent gas wells which is less expensive, does not kill the reservoir and maintains an operable sub-surface safety valve. Even though liquid loading is a dynamic process, using PIPESIM provided very useful clue to estimate the liquid loading velocity ratio which was among the main design parameters.”

David Carr, Senior Vice President – International at Helix Well Ops, will be hosting a session at the upcoming Offshore Well Intervention West Africa (OWI WA) which will look at the potential for light well intervention (LWI) in Africa.
Exclusively for attendees of the event, which is arriving in Accra from 12-13 July, Carr will examine examples of innovative LWI vessel based solutions for complex well integrity issues and production enhancement purposes that improve the efficiency of well intervention projects.
Despite the seemingly incredible benefits that can be achieved through the use of such vessels, there remains somewhat of a reluctance to make use of them in the West African region. However, with Covid-19 forcing oil companies to keep hold of capital wherever they can, LWI could provide a viable outlet by offering them the chance to achieve their offshore objects but at a much lower cost.
Carr will continue the session by reviewing multi-service campaigns completed on an integrated vessel and how this can solve a variety of challenges operators face when embarking on intervention projects.
Those attending OWI WA will then have the chance to engage in a discussion with the Helix representative to explore how collaboration with an international and multi-disciplinary team can lead to seamless operational efficiency.
Such unique sessions are not to be missed by anyone involved in the African offshore industry or those interested in squeezing more from their offshore operations. To learn more, be sure to download the event brochure here:

C-Innovation, LLC (C-I), an affiliate of Edison Chouest Offshore (ECO) and its family of companies, have signed a two-year contract for continued Riserless Light Well Intervention (RLWI) services onboard the Island Venture offshore support vessel.
The new contract follows a previous agreement in which the Island Venture performed interventions on multiple deepwater wells in the Gulf of Mexico.
David Sheetz, C-Innovation’s Vice President, said, “This new award is a continuation of nearly three years of setting new standards in the RLWI space. We are constantly working to change the way the industry looks at RLWI work to increase production in this ever-changing market. We look forward to the next few years on this project, and we are already making plans to expand the offering, including numerous dock upgrades to facilitate even more efficient fluid handling and waste removals to minimise required between-wells maintenance time.”
With no safe vertical access to several subsea wells under a platform, the C-I Subsea Projects Group was able to find a solution by utilising a well service jumper to perform well interventions. This collaborative effort between C-I and the operator allowed C-I to perform the intervention without disrupting the platform’s operations.
George Wilson, C-I’s RLWI project manager, commented, “C-I is committed to ensuring the continual improvement of the quality, health, safety and environmental aspects of its operations and services. The two-year RLWI work is no exception: with over one million man-hours, C-I had zero recordable incidents. So far this year, C-I has clocked over 135,000 hours with no recordables.”
Sheetz added, “The contract award for additional RLWI work is a credit to the entire RLWI team. Our team continues to provide creative solutions and methodologies to perform interventions that have not been achievable from a conventional RLWI approach. The collaboration of various subsea disciplines within our group has contributed to the successes, and our offshore teams continue to deliver on every execution that comes their way. C-I’s subcontractors, Halliburton, Baker Hughes and Caltex Oil Tools, were also key to the new award. I am extremely proud to work with some of the brightest people in our industry.”
