    Harts E&P’s 40 Under Forty Award

    Artem Khasanov, TGT’s QHSE & Testing Laboratory Team Leader is an honoree in Hart Energy’s E&P 2021 “40 Under Forty” recognition program Article featured in Harts E&P Magazine   From an early age, Artem Khasanov was interested in learning how the world works, so he started studying physics and technology. Khasanov studied physics at Kazan Federal University, where he was first engaged in semiconductors research and then, in collaboration with the Kazan Institute of Chemical Technology, was engaged in research of silicone rubbers.   “I am 107% sure (this is an accurately measured value) that the main quality of a researcher and developer is the ability to be a good observer,” he said. “Many secrets of the world are revealed if you are thoughtful enough.”   In 2013 Khasanov started working with TGT as a laboratory assistant, and he became a research engineer a year later. He added, “Once I realized that there is an industry where people who are passionate about technology and research are rewarded well—the oil industry—there was no stopping me!”   In 2019 Khasanov became the head of the testing laboratory. He devoted a significant part of his work to the study and application of ‘acoustics’ in oil and gas wells, as a means to locate and characterize fluid flow. Acoustic technology is a key ingredient in TGT’s diagnostic systems—used by its customers globally to keep wells safe, clean and productive. Career goals “When I started my career, I met so many competent and talented people who strive to innovate and develop new technologies. My first task was to catch up with my peers in terms of competence and knowledge. Now I am studying international quality standards to ensure that our diagnostic systems and products continue to set and exceed industry standards.” Memorable technology projects “I have led several projects that have helped the company advance diagnostic methods and technology. For example, I designed and manufactured laboratory models for researching and developing sophisticated multisensor acoustic devices. I also developed systems to study the acoustic signature of fluids flowing through rocks and barrier leaks, as well as apparatus to study the acoustics of sand production; and automatic testing devices for our diagnostic systems. All of these projects ultimately help our customers make better-informed decisions.” Motivation from within “After a certain age, a person needs to stop looking for a mentor and become one. All the necessary information is available; you should just lend a hand. You don’t need a mentor to make history. All you need is purpose, motivation, and health. And believe it or not, your best advisor is – yourself! One of my guiding principles is, ‘If you are in doubt about what to do, just do what is right.’” Formative experience “The most important thing in any business is to control emotions and direct personal energy to an ultimate goal. Therefore, among the many educational programs I’ve undertaken, one of the most useful was all about emotional intelligence.” Sustainability & decarbonization “Whilst renewable energy sources are gradually increasing, more than 50% of the world’s energy supply still comes from hydrocarbon resources – so the extraction of oil and gas is a necessity. Our mission at TGT is to help the industry keep oil and gas wells safe, clean and productive. We are helping our customers to decarbonize and reduce harmful emissions. I’m motivated by the fact that the diagnostic systems and products that we create make it possible to use the planet’s resources more sustainably.” Industry’s future “I believe that the ultimate goal of any industry is to make our lives healthier, happier and more sustainable. Collectively, we need to find the right balance between maintaining human existence and protecting the planet and other species that live beside us. We need to keep in mind the countless scientists, engineers, analysts and other oilfield workers who dedicate their lives to advancing this vital industry. Digitalization and automation will be important enablers of our future, together with the use of predictive diagnostics to improve the safety and integrity of well systems. “One day, after a couple of hundred years, our great-grandchildren, roasting marshmallows by the fire on Mars, will remember us with gratitude.”   Artem Khasanov, TGT’s QHSE & Testing Laboratory Team Leader

    Harts E&P Article – 2021 Hydraulic Fracturing Technology Showcase

    Exert from Harts E&P's showcase on the latest hydraulic fracturing technologies and how they aim to address operator challenges. Diagnostics locate flow before or after fracturing TGT’s Fracture Flow evaluates the effectiveness of a fracturing program. It uses the Chorus acoustic platform to record and analyze the acoustic wave propagation in the wellbore and rocks, plus well design information, to determine the location of the acoustic source energy produced by fluid flow in the fractures. When used during pre- and post-fracturing, it can analyze the reservoir flow profiles, qualify flow to or from the fracture network, reveal fracture density and identify unwanted fracture components that impact product. The technique can identify the location and determine the distance of the acoustic signal from the receiver. Combined, these insights offer operators the diagnostics they need to improve their fracturing program, so it can be targeted and optimized to deliver maximum time and cost efficiencies. The logplot shows a horizontal tight sand gas condensate producer, completed with a non-cemented multistage ball-activated application. Stage separation was achieved by a dual hydraulic-activated packer. The results identified the presence of 22 active fractures, 17 were offset from flow ports and five could be aligned with the flow ports producing a unique signature covering a wide frequency range. The fracture distribution varied between stages with an average of three active fractures per stage.

    ‘Industry-first’ solution to combat sand control failures

    Dubai, 8 September 2020 - Independent global completions service company Tendeka and diagnostic specialists TGT have agreed a partnership to mitigate the costly consequences of sand control failure in wells.   The remedial sand control collaboration known as ‘Find Fix Confirm’, will see TGT’s Sand Flow product used to accurately identify the locations of sand ingress within the wellbore. Then, Tendeka’s Filtrex  thru-tubing sand control system is precisely situated to quickly repair the damage. Crucially, the service can confirm the effectiveness of the solution with the redeployment of TGT’s diagnostic product.   In mature basins, sand issues can account for up to 10% of all shut-in wells either due to failure of the existing downhole sand control or onset of sand production due to pressure depletion and/or water production.   Launched in 2019, Tendeka’s Filtrex solution is a one-trip remedial system enabling sand-free production to be restored effectively and efficiently. It is fully compatible with thru-tubing operations, even through the tightest of restrictions. The first of its kind, Filtrex can perform sand clean out and chemical treatments during live well deployment.   TGT’s Sand Flow product precisely locates sand entry to the wellbore and provides a qualitative sand count, clearly identifying problem zones, even in turbulent flow conditions. Delivered by the ‘True Flow’ system with ‘Chorus’ acoustic technology, Sand Flow provides the clarity and insight needed to manage sand production more effectively. Although commonly used to diagnose a known sand production issue, it is also used proactively to ensure downhole sand control measures are working correctly.   Paul Lynch, Advanced Completions Director at Tendeka said: “The management and control of sand production is an inherent problem in the oil and gas industry. Often, the first indication of sand issues downhole will be as a result of detrimental effects that can occur at surface, such as fill in separators or erosional damage to pipe work, ultimately resulting in a shut-in well. Existing solutions have been extremely limited due to their high cost and/or poor performance.   “Our Find Fix Confirm sand remediation service addresses both issues to offer a more effective, intervention-based solution. We believe this is the first time a specialized, integrated tool can fully understand and fix sand production issues, to ultimately maintain asset integrity and extend the product life of the asset. We are already seeing significant interest from operators around the world.”   Ken Feather, Chief Marketing Officer at TGT commented: “Proper diagnosis is the critical first step to any kind of well remediation planning and execution. But determining the precise location and extent of sand ingress downhole has challenged the industry for decades, as previous attempts were unable to reliably distinguish between sand and fluid flow.   “Our Sand Flow diagnostics are powered by Chorus technology which captures and decodes the acoustic signature generated by sand particles entering the wellbore to reveal sand ingress locations and sand count. Equipped with that information, Filtrex can be targeted to repair the breach, then Chorus can be deployed again to confirm that the breach is fixed. Overall, Find Fix Confirm enables better use of resources and more reliable sand control outcomes.”   The ‘Find’ element of the solution will see TGT’s Chorus acoustic sensing platform deployed in hole on wireline to pinpoint sand entry locations utilizing time-domain analysis. By flowing from the reservoir whilst the tool is in the well, the acoustic signature of any sand within the production stream can be characterized such that the sand entry points, particle size and volume can be identified.   The ‘Fix’ aspect will see Filtrex deployed via coiled tubing into the well and positioned across the target area. By dropping a ball from surface, a simple two stage application of pressure firstly sets the anchor, and secondly releases the compression sleeve. Upon removal of the sleeve the matrix polymer expands to contact the wellbore and the deployment string can be retrieved from the well. Filling the annular gap with the open cell matrix polymer prevents further ingress of formation solids into the wellbore whilst still allowing passage of liquids or gases.   Lastly, is the ‘Confirm’ stage. Here, the Chorus tool is deployed again but this time passed through the internal diameter of the Filtrex system to confirm that no sand is entering at that depth.

    Case Study Multi Seal Integrity

    Challenge A 60-year old well in the Chadar field, Libya was exhibiting a leak at surface and sustained pressure in all three annuli – A, B and C. The age of the well coupled with the symptoms suggested a complex multi-barrier failure scenario that needed to be diagnosed quickly and accurately so that the well could be secured safely. Multi Seal Integrity example well sketch. Multi Seal Integrity evaluates the seal performance of multiple barriers, locating leaks and flowpaths throughout the well system, from the wellbore to the outer annuli. Delivered by our True Integrity system with Chorus, Indigo and Maxim technology, Multi Seal provides a clear diagnosis of leaks and rogue flow paths so the right corrective action can be taken. Multi Seal is used in a targeted fashion to investigate a known integrity breach anywhere in the well system. Barriers can also be validated proactively to confirm integrity. Either way, Multi Seal provides the insights needed to restore or maintain a secure well. Solution The customer selected TGT’s ‘Multi Seal Integrity’ diagnostic product to locate the source of pressure and associated flowpaths. Multi Seal Integrity diagnostics are delivered using TGT’s proprietary True Integrity system, leveraging a combination of key technology platforms applied by diagnostic experts using a methodical workflow. In particular, Chorus acoustic and Indigo multisense technology were utilised to precisely locate seal failures and associated flowpaths throughout the well system, from the reservoir, through barriers to the wellbore.   The critical first step in applying the True Integrity system involves developing a customised diagnostic programme that would ’stress-test’ the well whilst Chorus and Indigo sensors recorded the resulting well dynamics downhole. Data acquired during the programme was then processed and analysed by experts using a third platform, the Maxim digital workspace.   The diagnostic programme involved activating the well in four well state scenarios; one shut-in, and the others bleeding-off each of the three annuli. In the shut-in state, pressurised fluids from inside the tubing enter the A-annulus at three distinct points – X2000 ft, X4800 ft and X6400 ft. The fluid then enters the B- and C-annuli at X3600 ft via failures in the 7” and 9-5/8” casings. Fluid in the C-annulus then re-enters the formation via a failure in the 13-3/8” casing at X0900 ft. In the B-annulus bleed state, fluid from within the tubing follows the same flowpaths as in the shut-in state but in addition, formation fluid is entering the C- and B-annuli at X3600 ft. Result The True Integrity system successfully identified the sources of pressure and revealed a highly-complex geometry of interconnected flowpaths between several formation layers and through multiple tube and cement barriers.   Equipped with a complete diagnosis, the operator was able to design and execute an appropriate P&A programme to secure the well permanently, eliminating any further risk to people and the planet.
