The industry’s most advanced acoustic sensing and analysis platform Bringing a new level of clarity, precision, and certainty to well system acoustics A flowing well is full of sound encoded with information about the flow that created it. This, and the fact that sound energy penetrates through well and reservoir materials, is why acoustics has become a powerful diagnostic technique for locating and characterising flow. However, the fidelity and resolution of the sound recording, and the effectiveness of processing and analysis technologies all have a direct bearing on the accuracy and certainty of the diagnosis and resulting decisions.   The well reservoir system is a challenging environment for capturing and analysing the high-fidelity sound required for precise diagnostics. There is a combination of materials and fluids with different acoustic properties, multiple boundaries and mechanical noise that act together to create a complex spectrum of acoustic energy. Decoding the sound and extracting useful flow information from this cacophony requires a special combination of technology, expertise, and experience.   TGT has been advancing the use of acoustics to locate and characterise flow in the well system for two decades. The Chorus brand is already recognised for its sensitivity and dynamic range when capturing high-fidelity flow sounds. Our new generation ChorusX platform takes this acoustic capability to a whole new level to deliver exceptional precision, clarity and certainty. ChorusX brochure ChorusX ingredients ChorusX is the sum of many parts that work in concert to deliver a range of important benefits to analysts and customers. Each ingredient is special in its own way, but the big wins occur when they are multiplied together.   Features Explained Benefits ChorusX has been designed to overcome the limitations of conventional acoustic technology and to provide the three essential capabilities of an effective flow-finding resource.   Reach Ultrahigh sensitivity and extreme dynamic range give ChorusX the spatial and audible reach to record the furthest and quietest flows.   Identify Four new high-definition acoustic maps enable analysts to recognise and distinguish different types of flow easily and confidently.   Locate Eight high-definition array sensors and a unique phase analysis engine work join forces to pinpoint flow sources everywhere in the well system in depth, and radial distance. Diagnostics products and applications Well systems perform by connecting the right fluids to the right places, and mapping flow dynamics downhole is essential to keeping wells safe, clean and productive. ChorusX provides asset teams with the flow insights they need to manage well and reservoir performance more effectively.   As an integral part of TGT’s ‘True Flow’ and ‘True Integrity’ diagnostic systems, ChorusX capability is available through a range of application-specific answer products. Through these answer products, ChorusX delivers clear, complementary answers that enable analysts and customers to reach an accurate diagnosis more efficiently. A robust and accurate picture of the well system enables better decisions and positive outcomes. This means that, when remediation plans are being implemented, there is a greater prospect of first-time success.   True Flow products help asset teams to understand flow dynamics between the reservoir formations and the well completion. Notably, these answer products reveal flow where it matters most—at the reservoir. Some of the distinct True Flow applications and benefits brought by ChorusX include fracture assessment, delineating active formations, and distinguishing between reservoir flow and completion flow.   True Integrity / Seal Integrity products help asset teams to validate the performance of seals and barriers throughout the well system, including packers, cemented annuli, tubulars, and valves. Typical applications for ChorusX include revealing low-rate leaks, tracing the source of B and C annulus pressure, and resolving leaks in close proximity to each other.

PollutionPollution Overview Reduce fugitive emissions Secure abandoned wells Eliminate Pollution Go to section OverviewReduce fugitive emissionsSecure abandoned wellsEliminate Pollution Home Search Results Oil and other liquids can leak from active wells and abandoned or ‘orphaned’ wells. TGT diagnostics locate the source and flowpaths of rogue leaks so they can be sealed off, reducing pollution.Reduce fugitive emissions Well systems are designed to connect high-pressure oil or gas in deep underground reservoirs to surface flowlines securely with full containment. Rigorous industry standards necessitate the presence of at least two ‘integrity barriers’ between produced fluids and the environment outside of the well system. Occasionally, one or more barriers can fail allowing fluids to escape, sometimes with dire consequences.   Apart from the major oil leaks that make headlines, some smaller oil and gas leaks can continue undetected for years, especially if they are hidden underground or migrate far from the well system. TGT’s Seal Integrity products are designed to locate even the smallest seal failure anywhere within the well system, enabling precise targeted repair. Used proactively, the same diagnostics can be used routinely to ensure well barriers are intact at all times, reducing fugitive emissions. MULTI-SEAL INTEGRITY CASE STUDY Methane emissions from upstream oil and gas operations are 1.9 GtCO2e annually. Secure orphan and abandoned wells Orphan wells typically have no legal owner and may have been abandoned without undergoing a proper decommissioning or plugging process. Methane or liquid emissions from orphan wells can be significant contaminants, especially when the number of orphan or incorrectly decommissioned wells is thought to be in the millions globally. The burden of responsibility for these wells typically falls with operators, regulators or local government, and permanently sealing them is a top priority.   Validating well barrier status and revealing emission sources downhole inside the well system is the first step in sealing these wells properly. TGT’s Seal Integrity and Tube Integrity surveys are used to achieve exactly that. Precision diagnostic insights inform and guide the decommissioning agent to design and execute an effective plugging programme. This approach is equally applicable for any well decommissioning operation, not just for orphan wells, helping operators to secure them efficiently and cost effectively. Regulators estimate >3.5 million abandoned wells in US emit 7.1 mtCO2e annually. Eliminate pollution According to the ISO standard for ‘well integrity’ (ISO/TS 16530-2), a typical well system contains 26 potential leak paths that could lead to fluids escaping the well system. This is why the standard calls for a ‘dual barrier’ approach underpinned by routine testing of well barriers. Despite these efforts, oil or other harmful fluids such as hydrogen sulfide (H2S) can sometimes spill to the environment.   In most cases these spills are visible or detected quickly, enabling operators to take urgent action. However, sometimes they may go undetected for months or years because there is no visible warning. An example of this might be oil or gas flowing to and contaminating aquifers. TGT’s Seal Integrity answer products are specifically aimed at locating unwanted fluid flow anywhere within the well system, enabling precise targeted repair. Used proactively, TGT diagnostics can be used to ensure well barriers are intact at all times, reducing the risk of pollution. PRIMARY SEAL INTEGRITY CASE STUDY A typical well system has 26 potential leak points.

FlaringFlaring Overview Reduce flaring Go to section OverviewReduce flaring Home Search Results Gas flaring contributes significantly to upstream sector emissions. TGT’s diagnostics locate the source of unwanted gas enabling it to be sealed off, thereby reducing the need to flare.Reduce flaring At an estimated 310 MtCO2, routine and non-routine gas flaring is one of the largest and most pervasive sources of upstream CO2, accounting for ~30% of all upstream emissions globally. During oil production, associated gas is produced from the reservoir together with the oil. Much of this gas is utilised, but excess gas is flared because of technical, regulatory, or economic constraints. Understanding the source is a key step in minimising the flaring of excess gas.   If unwanted gas is produced unexpectedly from targeted or non-targeted formation layers, it may be possible to shut this off if the source can be precisely located. Conventional well diagnostics can locate where gas is entering the wellbore, but not always the true source. TGT’s True Flow and Seal Integrity products can identify the primary source and pathways of unwanted gas from formations beyond the wellbore, even behind casing. This can lead the way to stopping the gas and its associated flaring. Flaring is responsible for more than 30% of all upstream CO2 emissions.

Water managementWater management Overview Resource management Improve injection performance Reduce water production Go to section OverviewResource managementImprove injection performanceReduce water production Home Search Results Water is a precious natural resource that is used prolifically by the industry for a wide range of purposes, such as drilling, reservoir injection, cementing and hydraulic fracturing.Improve natural resource management Water is a precious natural resource that is used prolifically by the industry for a wide range of purposes, such as drilling, reservoir injection, cementing and hydraulic fracturing. Water can come from recycled sources, but in some areas it is sourced from natural aquifers or the oceans, and this can cause an ecological imbalance. It’s important that water is used sparingly and efficiently.   Apart from the large amounts of water used for injection, hydraulic fracturing and chemical also needs huge amounts of water to be effective. TGT has developed two specific answer products in our True Flow range that help operators assess the effectiveness of fracturing and stimulation operations—Fracture Flow and Stimulate Flow. These surveys can be deployed pre- and post-operations to help optimise fracturing and stimulation programmes, and potentially reduce associated water usage. RESERVOIR FLOW CASE STUDY A typical hydraulic fracturing job uses 5-10 million gallons of water per well. Improve injection performance Most oil reservoirs will inevitably require additional pressure support to maintain production and improve oil recovery. Water injection is used widely for this purpose and many oilfields are injected with tens to hundreds of thousands of barrels per day. Pumping water is energy intensive and the resulting CO2 emissions can range from 1-2 kgCO2 per barrel. In fact, water injection is responsible for ~40% of total CO2 emissions for a typical oilfield.   Making matters worse, well completion and formation integrity issues can lead to water being diverted away from the target reservoir. This can result in abnormally high injection rates, reduced field production performance, and high water cut in producer wells. TGT’s True Flow products are being used globally by operators to ensure that all injected water is reaching the target and revealing where it is not. In many cases, these diagnostics lead to a significant reduction in water volumes and CO2 emissions, and increased field production. RESERVOIR FLOW CASE STUDYFIBRE FLOW CASE STUDY Pumping 10,000 barrels of water per day produces 5.4 ktCO2 annually. Reduce water production High water cut is a persistent industry challenge responsible for unnecessarily high CO2 emissions and higher carbon per barrel. Excess water needs to be managed at surface, treated then reinjected or disposed of, and this requires energy. Also, excess water often means less oil, reduced recovery and longer production times, increasing emissions even further. And complicating the issue, produced water may be channeling from several elusive sources hidden behind the casing.   In many cases, excess water cut can be minimised or cured. If the operator can identify the true source of water downhole, measures can be taken to shut-off the water and restore oil production to lower carbon and economic levels. TGT’s True Flow products are used widely for this purpose. Unlike conventional diagnostics that can only detect water entering the wellbore, TGT’s through-barrier diagnostics can reveal the true source behind casing, enabling effective remediation, improved recovery rates and reduced carbon emissions.

Energy and resource efficiencyEnergy and resource efficiency Overview Infrastructure performance Intervention efficiency Improve injection performance Reduce water production Go to section OverviewInfrastructure performanceIntervention efficiencyImprove injection performance Reduce water production Home Search Results Producing hydrocarbons requires energy. Turbines and diesel generators account for 70% of upstream CO2 emissions. Our diagnostics can help you become more energy efficient and reduce your carbon overhead.Improve infrastructure performance Building and operating hydrocarbon extraction infrastructure represents a huge investment in energy, capital, time, materials and people resources. Maximising the return on that resource must be achieved, while protecting people and the planet. If a well or reservoir is not producing to its full potential during its life then the resource that built or operates it is not being fully leveraged and some is being wasted. Equally, if maintenance and workover resources are being utilised, they should operate efficiently and contribute to overall asset performance with the goal of keeping wells safe, clean and productive.   All TGT diagnostic products are adept at revealing inefficiencies and guiding measures that enable existing infrastructure and resources to operate at maximum efficiency. For example, if a well is producing at high water cut, our Total Flow product will reveal the exact sources of water to enable targeted remediation. True Integrity products can be used proactively to identify casing weakness before the casing fails, helping to maintain asset performance and preventing more costly scenarios. Equally, because workover and rig resources are better targeted, time and energy is saved in getting the job done right first time. TOTAL FLOW CASE STUDYPRIMARY SEAL INTEGRITY CASE STUDY Drilling a single deepwater well can produce more than 20 ktCO2 Improve intervention efficiency Well delivery and intervention operations such as drilling, fracking, workovers, decommissioning [P&A] and diagnostic surveys require energy intensive surface equipment. Rigs, trucks, and pumps derive power from diesel engines or gas turbines that emit CO2 when the fuel is burned. A typical semi-submersible drilling rig emits roughly ~130 tCO2 per day and a Light Well Intervention vessel around 30 tCO2 per day. Improving efficiency and minimising the time to perform operations is a key factor in reducing energy consumption and emissions.   All TGT diagnostic products deliver insights that enable all types of operations to be carefully planned and precisely targeted so they can be executed efficiently with precision. Also, by enabling ‘lighter’ or ‘rigless’ interventions, our diagnostics can be deployed with minimal carbon footprint before heavier equipment is mobilised. Lastly, because through-barrier diagnostics provide a more complete picture, we provide maximum information in the minimum amount of time. Time savings translate to both cost and carbon savings and our aim is make every hour count. MULTI TUBE INTEGRITY CASE STUDY A typical Jack-up rig emits 70 tCO2 per day. Improve injection performance Most oil reservoirs will inevitably require additional pressure support to maintain production and improve oil recovery. Water injection is used widely for this purpose and many oilfields are injected with tens to hundreds of thousands of barrels per day.

In fact, water injection is responsible for ~40% of total CO2 emissions for a typical oilfield.   Making matters worse, well completion and formation integrity issues can lead to water being diverted away from the target reservoir. This can result in abnormally high injection rates, reduced field production performance, and high water cut in producer wells.

Enabling cleaner energyEnabling cleaner energy Overview Secure gas storage Go to section OverviewSecure gas storage Home Search Results To reduce carbon emissions, society needs to switch from fossil fuel energy to alternatives. However, non-fossil sources only satisfy 17% of the world’s energy demands. As a transition fuel, gas offers a cleaner alternative to coal, provided it doesn’t leak from infrastructure.Secure gas storage To reduce greenhouse gas emissions, society needs to switch from fossil fuel energy to alternative forms. In 2020, only 17% of the world’s energy came from non-fossil sources, 31% came from oil, 25% from gas, and 27% from coal. At 56% of the energy mix, oil and gas are still essential. Whilst oil and coal use are in decline, gas use is trending up.   Gas is the cleanest burning fossil fuel, but with the increase in use comes the risk of methane leaks in production and storage wells. Since methane is 85x more potent as a greenhouse gas than CO2, the integrity of producing and storage wells is essential in enabling cleaner energy solutions. Used proactively, TGT’s True Integrity diagnostics can be used routinely to validate seals in gas producing and storage wells, and assure methane containment. Burning 1kg methane produces twice the energy and half the CO2 than 1kg coal

Carbon capture and storageCarbon capture and storage Overview Store captured carbon Go to section OverviewStore captured carbon Home Search Results Reducing the level of carbon in the atmosphere to safe levels requires significant carbon removal. Captured carbon is stored underground in depleted oil and gas reservoirs. TGT diagnostics can monitor the integrity of storage wells to ensure gas isn’t leaking back out.Store captured carbon Reducing the level of carbon in the atmosphere to safe levels will require both a reduction in emissions and a significant carbon removal programme. In fact, experts indicate that even if we reduce emissions to zero, existing carbon gases need to be removed from the atmosphere to prevent further climate change. Carbon capture facilities of all types are emerging globally, and some involve storing CO2 underground in depleted oil and gas fields.   Storing CO2 underground is similar to methane storage. Well and reservoir integrity is vital to avoid leakage. TGT’s True Integrity products can be used to validate integrity prior to re-purposing existing well systems, and True Flow products can be used to ensure that 100% of the injected gas is reaching the target formations. And just like conventional producing well systems, storage wells can be monitored routinely to ensure integrity compliance. Experts indicate that even if emissions are reduced to zero, existing carbon gases need to be removed from the atmosphere to prevent further climate change.
