Overcoming Challenges in Chemical EOR During Polymer Breakthrough
The complete paper discusses the importance of adequate preparation and the approaches used to overcome challenges of EOR operations, including handling back-produced polymer.
Four-Injector Polymer Pilot Expands to 80 New Injectors Using Modular Concept
The complete paper presents steps to accelerate enhanced oil recovery (EOR) in a Grimbeek field from a four-injector pilot to 80 new injectors in a rapid deployment.
Low-Toxicity Polymer Fluid Developed for Environmentally Sensitive Offshore Drilling
Aggressive Stimulation Design Yields Better Returns
The authors examine methods of adopting an aggressive approach to optimizing stimulation design to lower the break-even level of operations and evaluate the results.
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
Modeling, Monitoring Aid Fight Against Scale in Alkali-Surfactant-Polymer Floods
Two alkali/surfactant/polymer (ASP) floods became operational in the Taber area of Alberta, Canada, in 2006 and 2008.
Polymer-Flooding Pilot Finds Success in Previously Waterflooded Reservoir
A successful pilot test of polymer flooding was conducted in the San Jorge Gulf basin.
Wintershall Sees EOR Promise in New Biopolymer
After a year of field testing, a new type of biopolymer developed by Wintershall, Germany’s largest oil and gas producer, is showing promise as an effective enhanced oil recovery (EOR) tool in one of the country’s longest producing oil fields.
