Enhanced recovery
The application of an extended-release scale-inhibitor in approximately 70 vertical conventional wells in the Permian Basin has shown approximately three times better performance compared to the incumbent chemical.
Finding creative ways to drive down the CAPEX and discounted OPEX and define a realistic pathway and schedule to full-scale commercial operations is discussed.
Operator will use polymerized water into reservoir to boost oil and gas recovery.

The paper evaluates the effect of different injection methods on oil recovery and CO2 storage potential in a depleted sandstone reservoir in the Norwegian Continental Shelf. -
Our industry has been the custodian of subterranean reservoirs. We are the experts in managing and developing them. Why not use that expertise to find solutions for climate change by capturing and removing carbon and being part of the solution?

Case studies demonstrate how an autonomous outflow-control device prevents growth and excessive fluid injection into thief/fracture zones and maintains a balanced or prescribed injection distribution.

This paper presents recent results from a rigorous pilot-scale demonstration of natural-gas foam over a range of operating scenarios relevant to surface and bottomhole conditions with a variety of base-fluid mixtures.

The complete paper reviews the history of enhanced oil recovery and the Scurry Area Canyon Reef Operators Committee, discusses changes in theory over time, and provides a look at the field’s future.

The authors demonstrate how reservoir management and operational strategies can be used to optimize CO2 storage and oil recovery.

Hydrochloric acid continues to be the most effective and low-cost material for carbonate stimulation. Though exotic chemistries such as chelating agents and organic acids have been promoted for being less corrosive at high temperatures, the cost and dissolving capacity limit their use to large-scale implementation. The ability to inhibit the corrosion tendency of hydr…

Using validated models, the authors provide a comparative analysis to determine the advantages of using natural gas foams relative to conventionally used slickwater, linear gel, and crosslinked fluid.

The water-shutoff technique is used in some wells of the U reservoir in the Iro field of the Oriente Basin in Ecuador to restore production after an early water breakthrough. This paper compares the production historical data, workovers, and sand-body correlation of wells to understand reservoir behavior, shale-baffle-sealing continuity, the existence of different san…

The authors demonstrate that alternating injection of polymer and water is effective and economical for heavy oil fields, even offshore.
