3D model with a digitized paper contour map (with horizontal well lines) draped on the reservoir surface with colored contours blended. Good correlation exists between the two sets of contours. Vertical wells are shown in yellow and directional wells are in green. A smaller detailed property model can be seen near the center showing gamma…
Visualization and analysis of previous fracturing operations in adjacent wells can help guide planning and development of infill drilling and in new unconventional reservoirs. CoViz 4D offers the ability for asset teams to integrate, visualize and analyze relevant data to reduce cost and risk, and maximize hydrocarbon recovery. Hydraulic fracturing in unconventional reservoirs is not…
Integrating subsurface data from existing vertical wells can greatly assist targeting and placement of infill horizontal wellbores. CoViz 4D enables a high degree of data integration and collaboration across the asset and adds value to analysis and decision-making.

The interest in geologic carbon storage is on the rise. It’s proving to be an effective method to reduce CO2 emissions in an effort to mitigate climate change. Geologic carbon storage can serve several purposes—straightforward CO2 storage, injection into wells for enhanced recovery method, or storage of natural gas for commercial use. Injecting gas into…
Enhanced geothermal systems or engineered geothermal systems (EGS) offer significant opportunities to take advantage of geothermal energy. EGS are different from conventional geothermal wells. They are located significantly deeper and require fracturing rock to create the artificial circulation system. Lessons learned from unconventional well development in the petroleum industry are benefitting the development of EGS.…
Because of the inherent uncertainty and risk in the process, drilling operations account for a significant share of expenses in the development of oil and gas reservoirs. However, the wealth of geological and petrophysical data available to reservoir engineers can significantly reduce drilling risks. Improvements in drilling technologies, specifically the instrumentation of bottom hole assemblies…
Steam-assisted gravity drainage (SAGD) methods have proven their effectiveness in economic oil recovery in Alberta and California, frequently achieving a 60% recovery factor. The placement of horizontal laterals within a field and the vertical separation of well pairs (injector and producer) are critical decisions in any SAGD well completion design. Every SAGD opportunity presents geologists,…
Well spacing is one of the most critical factors affecting onshore well production. Reservoir teams striving to optimize well spacing can utilize the wealth of data that describe subsurface environments to achieve that goal. In particular, geologists, well planners, and drilling and completion engineers can benefit from 3D visualizations of geologic and petrophysical data, existing…
