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.

Methane emissionsMethane emissions Overview Stop methane venting Secure abandoned wells Emissions Go to section OverviewStop methane ventingSecure abandoned wellsEmissions Home Search Results Oil and gas producers vent leaked methane from casing cavities to reduce pressure. TGT’s diagnostics can locate the source and flowpaths of rogue gas leaks, ensuring they can be sealed, thereby reducing the need to vent.Stop methane venting Sustained annulus pressure (SAP/SCP) is caused by a build-up of fugitive fluids such as gas in the annular spaces surrounding well system casings. The casings are designed to withstand high pressure but if this pressure is reached, the gas is diverted to the production stream or vented to atmosphere. The global warming potential of methane is ~80x that of CO2, so even small amounts are damaging and must be contained.   These rogue fluids reach the annulus via seal failures and flowpaths that begin at hydrocarbon-charged formations and continue towards surface causing a build-up of annulus pressure. TGT’s True Flow and Seal Integrity products can locate the source of annular fluids and trace the flowpaths, enabling well operators to target effective repairs and eliminate SAP-related methane venting. Methane has 85x higher global warming potential than CO2.

Flow diagnostics perfected for horizontal wells TGT’s Horizontal Flow product powered by Cascade3 technology overcomes the drawbacks of conventional production surveys, delivering a continuous flow profile in a wide variety of completion and reservoir scenarios, including fractured formations.  Hydrocarbon reservoirs are generally more horizontal in shape than vertical, so it makes sense that horizontal wells drilled through them provide more contact and productivity than vertical wells. However, the economic and efficiency gains of horizontal wells is matched by the complexity of managing them and the reservoirs they drain. This hefty task rests with the asset teams that must recover the maximum quantity of hydrocarbons in the safest, cleanest, and most economical way possible. Horizontal Flow brochure TGT’s new Horizontal Flow diagnostics product has been created to provide asset teams with the flow insights they need to manage horizontal well and reservoir performance more effectively.   Underpinning Horizontal Flow diagnostics is the all-new Cascade3 flow analysis platform. Cascade3 is purpose-built for horizontal wells and incorporates the industry’s most advanced thermodynamic and hydrodynamic modelling codes to transform temperature, pressure, and other well system data into continuous reservoir flow profiles. Crucially, the flow profiles reflect flow activity in and out of the reservoir, delivering the truest picture possible of inflow and outflow downhole, even in the most challenging wells. Challenges Understanding flow dynamics in the well system is the key to unlocking better well and reservoir performance, and this is especially true for horizontal wells. Flow inside the wellbore of a horizontal well can be challenging to decipher, but flow outside is even more complex, and way beyond the reach of conventional production surveys.   Horizontal Flow powered by Cascade3 can decode the complex scenarios that are typical in horizontal wells, revealing flow where it matters most—at the reservoir. This enables asset teams to solve daily challenges with confidence and certainty. Accessing reliable flow profiles Locating water/gas breakthrough Maintaining an accurate reservoir model Measuring effective pay length Making accurate reserves assessments Revealing crossflow Assessing ICDs and packers Assessing fractures Making accurate production forecasts Optimising completion designs Benefits Horizontal Flow with Cascade3 is the most powerful flow diagnostic resource ever created for horizontal well systems. The range of benefits provided is perfectly aligned with the needs of Reservoir Engineers in managing reservoir performance, and Production Engineers in managing well performance. The accurate and continuous flow profiles from Horizontal Flow are fundamental to driving both.
