hpht well completion

Planning HPHT Well Completions

High-pressure, high-temperature (HPHT) wells—characterized by temperatures over 150°C and 10,000 psi at their deepest point—present challenges throughout all phases of the reservoir development cycle. The number of HPHT well completions have grown significantly in the past decade as improvements in data analysis and equipment designs allow operators to overcome the unique challenges of HPHT well…

oil well completion design

Enhancing Oil Well Completion Design Through Co-Visualization

Nearly every step in the development of a reservoir is critical in achieving the goal of maximizing hydrocarbon production. An initial geological analysis provides an understanding of subsurface conditions and an estimated ultimate recovery. Reservoir simulations and cellular gridding provide insight into fluid flows. Wellbore data helps geologists confirm or refine geologic models and completion…

subsurface geological modeling

Subsurface Geological Modeling: Subsurface Geology and Well Planning

Detailed subsurface geological modeling informs and supports asset teams at nearly every stage of the reservoir lifecycle. Geologists strive to create as accurate as possible geological models to allow petroleum engineers and other team members to better assess reservoir viability for further hydrocarbon exploitation. Subsurface geological modeling has many challenges and can be a time-consuming…

hydraulic fracture geometry

Understanding Hydraulic Fracture Geometry and Characteristics

Obtaining as accurate as possible an understanding of hydraulic fracture geometry provides many advantages to geologists, geophysicists, and completion engineers as they plan reservoir development. A detailed understanding helps asset teams determine fracking strategies for specific reservoir conditions, evaluate the results of individual frac stages, and continually improve hydraulic fracturing outcomes. Understanding hydraulic fracture geometry…

proven recoverable reserves

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…

recompletion of oil and gas wells

Data Visualization to Guide the Recompletion of Oil and Gas Wells

With easily recoverable oil either gone or continuously depleting, operators are evaluating previously-drilled leaseholds to determine if there are opportunities for further economically-feasible recovery through the recompletion of oil and gas wells. Improvements in production technologies and the ability to translate volumes of data obtained over the life of a reservoir into meaningful 3D visualizations…

water injection well design

Measuring the Impact of Proper Water Injection Well Design

One of the most common enhanced oil recovery (EOR) methods is water injection to restore pressure and return an oilfield to producing worthwhile amounts of oil, or to help free oil from subsurface formations so that it can be extracted. Unlike hydraulic fracturing, or fracking—where high-pressure water is injected to break apart petroleum bearing formations…
