Evaluate and quantify formation pressure Knowing reservoir pressure is fundamental to managing well and reservoir performance more effectively. But assessing formation pressure behind casing using traditional techniques can be costly, time consuming and disruptive. Reservoir Pressure provides formation pressure information behind casing, bringing the critical insights needed without the cost and disruption of more invasive techniques. Delivered by our True Flow system with Chorus (acoustic) technology and proprietary Polygon modeling code, Reservoir Pressure provides the clarity and insight needed to manage well and reservoir performance more effectively. Reservoir Pressure has become an invaluable resource for operators managing assets to improve or maintain well and reservoir performance.

Locate and quantify flow in dual completions Managing the performance of dual string wells is challenging. Access below the short string is often blocked meaning that conventional diagnostics can’t reveal flow where it really matters—at the reservoir.   Dual String Flow brings all the advantages of our Total Flow product to dual string wells. It locates and quantifies reservoir flow, even at the short-string reservoir.   Delivered by our True Flow system using the Chorus (acoustic) platform and the Cascade (thermal) platform; Dual String Flow provides the clarity and insight needed to manage well system performance more effectively.   Dual String Flow is used to diagnose unexpected or undesirable well system behavior, especially in relation to the short string. It can also be used proactively to ensure the well system is working optimally.

Target formation produces only oil from the upper part of the perforated interval (upper half of unit C). 35% of the total liquid production comes from behind casing crossflows from non-perforated units A and B, above the targeted formation. Unit B was initially saturated with water and most probably is the source of the high water content in the short string production.

Where heat measurements become flow insights Harnessing thermal energy to quantify flow, from the reservoir to the wellbore.   Fluids moving through the reservoir to the well system have thermal mass and can heat or cool the areas they touch. These temperature changes carry valuable information about fluid behaviour, particularly flow rates and profiles.   The physical laws of thermo-hydrodynamics are incredibly complex, and the interactions between them even more so. The 3D world of metal, concrete and earth that we call the 'well system' adds more complexity. Extracting accurate flow data from this environment can seem like an impossible task.   But not for Cascade.   TGT founded its business on transforming temperature changes into flow information, and since then we have taken this capability further than anyone.   Today, Cascade delivers that capability through our True Flow products to reveal flow like never before. Cascade architectureProgrammes & methodsTools & measurementsProcessing & modelingAnalysis & interpretationProducts Our approach We recognise that delivering accurate diagnostics requires not only the highest fidelity measurements, but also a system-based approach. It is important to have the best sensors and measurements, but it also important to use them in the right way and then to filter, process and model the data into tangible answers.   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.   Cascade is our thermal platform and, when in the hands of our engineers and analysts, can qualify and quantify any kind of flow event, critically reservoir flow, and reveal the relationship between the two. Pedigree Cascade diagnostic platform has been designed and engineered entirely in-house. More than 10 years of pioneering scientific research, ingenuity and direct field experience in applying thermal flow diagnostics to thousands of well systems globally.
