Well Spacing Optimization for Oil Well Design Completion

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…

Managing Subsea Well Completions: Saving Cost and Time

Offshore well development brings added complexity and costs that vary depending on sea floor depth and distance from onshore resources. Offshore rig time is expensive, ranging anywhere from USD $250K-$300K per day in 2020. Anything that can be done to reduce rig time positively impacts costs. Consequently, every phase of an offshore development project demands…

The Life Cycle of a Typical Oil Field: Improving Expectations

The life cycle of a typical oil field is defined by the need for oil companies to receive a return on the investment required to develop an oil field. This life cycle follows the five-step process of exploration, appraisal, development, production, and decommissioning. With the production phase being the only one to yield a profitable…

Assessing Proven Recoverable Reserves for Oil and Gas Reservoirs

Accurate reservoir characterization benefits every aspect of development and production activities. However, one of the greatest challenges of reservoir characterization concerns the diversity of data used by the individual disciplines of the reservoir team. Each discipline uses specialized software products. Each provides insight into a specific reservoir attribute such as pressure, fluid saturation, net-to-gross, or…
