gas injection

This paper studies the technical and economic viability of this EOR technique in Eagle Ford shale reservoirs using natural gas injection, generally after some period of primary depletion, typically through long, hydraulically fractured horizontal-reach wells.

The Eagle Ford formation has produced approximately 2 billion bbl of oil during the last 7 years, yet its potential may be even greater. Using improved oil-recovery (IOR) methods could result in billions of additional barrels of production.

In this paper, past gas-cycling operations were examined to identify subsurface implications and effects on operability aspects for the Arun giant gas field offshore Indonesia in the North Sumatra Basin.

The promise of getting 30% more oil production from shale wells has set off a race by companies trying to see if they can replicate what EOG has done. But the big question is: Can it add enough oil to increase the industry’s low average recovery rate?

This paper describes a gas-injection pilot that has been implemented in offshore Middle East carbonate reservoirs to assess injectivity, productivity, macroscopic-sweep efficiency, flow assurance, and operational efficiency in a field that has a long water-injection history.
