Subsurface trend analysis in the Gulf of Mexico

Jared Ciferno, Kelly Rose, Mackenzie Mark-Moser

The Subsurface Trend Analysis (STA) method is a data-driven approach, in which deductive geologic methods are integrated with spatiotemporal statistical autocorrelative methods. NETL has developed STA to better understand subsurface systems and predict their properties.

Exxon walks away from stake in deepwater Ghana block

Exxon Mobil is pulling out of a deep-water oil prospect in Ghana just two years after the west African nation ratified an exploration and production agreement with the U.S. oil titan.

Halliburton, TGS team up to bring advanced seismic imaging to fiber optic sensing

“This solution enables enhanced reservoir understanding for our customers with a lower total cost of ownership relative to conventional 4D seismic,” said Jan Schoolmeesters, executive vice president of TGS Operations and New Energy Solutions.

CGG and dCarbonX sign strategic agreement for decarbonization exploration

CGG has signed a strategic agreement to support dCarbonX in the subsurface assessment of its operated clean energy projects offshore Ireland and the UK, which include geothermal energy and storage sites for CO2, hydrogen and ammonia.

A machine learning workflow can quickly, and accurately, predict mineralogy, porosity and saturation in multiple wells to better understand productive layers in unconventional oil reservoirs.

Solid-state GWD system provides step-change in wellbore placement accuracy, collision risk mitigation

Fraser Cowie, Steve Thompson, Greg Belbin, Stephen Forrester

A first-of-its-kind innovation in wellbore surveying—a true solid-state GWD system—is achieving optimized reservoir placement and wellbore collision risk mitigation in several regions globally.

Definitive dynamic surveys: A long-awaited engineering innovation

Ross Lowdon, Shadi Altayeb Mussa

A survey-while-drilling service performs definitive dynamic analysis as the BHA rotates, providing significant rig-time savings compared to conventional static MWD surveys. The ability to see continuous real-time borehole conditions optimizes drilling, reduces risks and eliminates survey-related NPT.

Passive-magnetic ranging capability for relief wells in salt formations

Serge Roggeband, Koen Noy, Joe Burke, John Wright

A new triangulation method, using MWD survey data, provides operators a viable ranging and homing option for well control contingency planning.

Integrated diagnostics data advance infill development

Zachary Crowley, Mike Davies, Erica Coenen

Large-scale data accumulation is becoming more common in shale development. However, the industry struggles with a data dilemma. On the one hand, operators know that they have to gather data to learn and improve. On the other hand, the learning and analysis require so much manpower that often the collected data are left unexplored.

Advanced, process-based geomechanical modeling reduces risk in layered salt basins

Rajesh Goteti

Unique geomechanical modeling technique mitigates geological and drilling-related risk in basins with layered evaporite sequences, which are not amenable to traditional structural analysis methods.

Welltec wins role in DOE’s enhanced geothermal systems project

Welltec has been awarded a crucial role in a project funded by the US Department of Energy and led by the University of Oklahoma, to illustrate that near-field Enhanced Geothermal Systems can be successfully deployed.

CGG launches Walker Ridge reimaging program in the Gulf of Mexico

The Walker Ridge program covers approximately 300 OCS blocks including two priority areas of significant industry interest. Advanced proprietary imaging technologies will be applied to this program to unlock the full potential of existing seismic data and provide significant uplift in subsurface imaging.

CGG’s smart data solutions business wins data management contracts

Given the current industry context, these awards reflect the continued high priority that clients have on digitalizing and thus enhancing the value of their legacy data.

CGG commences second phase of largest OBN multi-client survey in UK CNS

CGG announced completion of the first phase of its multi-year program to deliver the largest OBN multi-client survey ever acquired in the UK Central North Sea and immediate commencement of the second acquisition phase.

Combining borehole images with deep shear wave imaging technology

Integrating imaging methods reveals sub-seismic features in the reservoir section and leads to a more accurate structural model of the subsurface.

CGG supports Australia’s acreage release

The industry-first basin-wide survey represents Phase II in CGG’s Gippsland ReGeneration reprocessing and acquisition project. Blocks V20-3 and V20-4 in the newly released Australian acreage are covered by the project.

Explor, Halliburton and AWS collaborate on cloud-based seismic data processing

"This outcome will drive a step-change in seismic data processing and is a key stepping-stone in the digital transformation of the global seismic industry. By reducing both timelines and the CAPEX burden on seismic data processors, the industry will be able to scale on demand as we acquire ever-increasing seismic trace densities," said Allan Châtenay, President of Explor.

Geoteric launches Collaborative AI and Geoteric Stratum seismic interpretation products

Collaborative AI enhances traditional interpretation, and efficiently extracts faults from seismic data at the click of a button – no requirement for network training. By moving from line by line manual analysis to Collaborative AI, the interpretation is augmented with artificial intelligence, which enables faster and more accurate results.
