Continuously improving the seismic image quality is key to Shell’s future exploration success in the Canadian Foothills.
First-order free-surface related multiples provide a wider seismic illumination zone than conventional reflections.
In 1986 Diamond Shamrock drilled through hundreds of feet of Gulf of Mexico salt and found a thousand feet of reservoir-quality rock beneath it — and the race was on.
A newly designed system offers vast improvements over conventional technology.
Traditional gas lift delivers only limited success in long interval environments. Newer techniques overcome shortcomings, but a single tool does not solve every problem.
Faced with trying to produce 8.6°API crude with viscosity beyond 10,000 cP, PdVSA found innovative solutions to lifting and metering problems.
Two recent projects in Argentina demonstrate how polymer gels can be effective in improving oil recovery in mature waterfloods.
Production optimization must extend across levels and be based on an integrated environment.
Unconventional oil resources are increasingly important in the quest for energy security. Global liquids discoveries have failed to replace oil production for more than twenty years, and there is concern that conventional oil resources will not be able to meet growing supply requirements to fuel worldwide economic growth.
Next-generation computed tomography (CT) scanning reveals the actual pore structure of shale reservoirs at the nanometer scale, and breakthrough algorithms compute the physical properties of shale from these 3-D images — all with unprecedented accuracy.
A company is examining the possibility of using microwave technology for extracting usable hydrocarbons from oil shale.
A new three-level well-life system is helping cement-job designers to diagnose problems in advance to build cement sheathes that maintain integrity throughout the life of a well.
Efficient fracturing techniques used with an appropriate multistage fracturing completion can achieve higher initial gas rates, increased recovery rates, and reduced completion costs.
A new mixed-integer constrained global optimization algorithm tackles oilfield production system challenges.
Operating companies that have been active in Atlantic Canada have teamed up to speed drilling programs that could lead to additional production offshore Newfoundland and Labrador.
