Advancement in Openhole Sand-Control Applications With Shape-Memory Polymer
This paper summarizes a technology using SMP to provide downhole sand control in openhole environments.
Enhancing Well Performance by In-Stage Diversion in Unconventional Wells
With multistage operations becoming the industry norm, operators need easily deployable diversion technologies that will protect previously stimulated perforations and enable addition of new ones. This paper reviews several aspects of the use of in-stage diversion.
Disappearing Downhole Tools Eliminate Need for Intervention
Development of a new polymer composite that degrades via hydrolysis in hot water or brine holds potential for use in structural applications for intervention-less downhole tools.
Polymer Injection in Deepwater Field Offshore Angola
The polymer-injection project in the Dalia field, one of the main fields of Block 17 in deepwater Angola, represents a world first for both surface and subsurface aspects.
Chemical EOR for Heavy Oil: The Canadian Experience
Chemical enhanced-oil-recovery methods such as polymer and alkaline/surfactant/polymer (ASP) flooding are generally not considered suitable for oil viscosities greater than 100 or 200 cp.
Drilling Fluid Uses Acid and Salt To Improve Well Performance
The inventor of a new water-based drilling fluid believes the chemical process involved with his technology opens up natural fractures as drilling takes place to increase production in shale formations.
Formation-Damage Diagnosis Facilitates Successful Remediation in Sandstone
Well-control fluids were used during a routine overbalanced workover operation in an offshore well completed in high-permeability sandstone.
Coiled-Tubing-Deployed Shutoffs in Alaska With a Polymer Gel and Microfine Cement
A common problem in oil and gas wells is excess free gas or water production from only certain portions of the completed interval.
Pilot to Full-Field Polymer Application in One of India’s Largest Onshore Fields
A normal five-spot polymer-flooding pilot has been conducted at the Mangala field, one of the largest onshore fields in India, and results are encouraging
