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.

Pioneering electromagnetics delivering highly accurate tube integrity diagnostics The miles of metal tubes that form the backbone of your well system are fundamental to its integrity. Tracking the condition and wall thickness of all tubes is essential to maintain a secure well.   The ‘electromagnetic signature’ of each tube contains information about the wall thickness, but extracting this accurately pushes the boundaries of electromagnetics, 3D modeling, and wellbore measurements to the furthest limits.   That’s exactly what we’ve managed to achieve with Pulse.   Pulse powers our True Integrity Tube products to accurately assess up to four concentric tubes from inside the wellbore. And unlike conventional systems, it works in all completion types, including dual string and corrosion resistant alloys.

Acoustic sensing and analysis platform, revealing flow throughout the well system Fluid flow in the well system creates a rich spectrum of acoustic energy that penetrates the surroundings. This acoustic wave is encoded with information about the type of flow, and its location.   But well systems aren’t ‘recording studios’. Sound frequency and intensity vary from barely imperceptible to deafeningly loud. Noisy interference can drown out important signals. And even if the acoustic wave form is captured faithfully, the link between flow and acoustics is so complex that translating it into reliable flow information is often beyond the reach of ordinary systems.   Chorus is not a tool nor is it any ordinary platform. It delivers incredible resolution and fidelity across the widest spectrum of useful acoustic energy.   Chorus is part of our True Flow System and is used to locate and characterise flow for our True Flow products. Chorus is also part of our True Integrity System and is used to validate sealing performance (confirming there are no leaks) in well system barriers in our True Integrity Seal products.

Therefore, we pursue a diagnostic system approach where multiple platforms come together, bringing their own unique diagnostic capability to be used in the framework of the proven workflow.   Chorus is our acoustic platform and when in the hands of our engineers and analysts, can precisely locate any kind of flow event within the entire well system.   Chorus platform follows a logical workflow where each part of the framework works to reveal a more complete picture of your flow within your well system.
