Field applications of resin for conformance improvement

Jump to navigation Jump to search

This page briefly describes some of the field applications of resin treatment for conformance improvement.

Water-encroachment treatments

Littlefield, Fader, and Surles[1] reports on 26 production wells of the Kern River and San Ardo fields that were treated in 1990 and 1991 with furan resin jobs in which the treated production wells were suffering from water-encroachment problems. Most (24) of the wells were in the heavy oil Kern River field of the Lower San Joaquin Valley in California. When the furan resin treatments were applied, the Kern River field was undergoing steamflooding. Of the production wells treated, 79% showed significant reductions in water production after the treatments. After drilling out the resin plug in the wellbore, the resin remaining in the treated perforations and in the treated formation was of a sufficient amount and strength to prevent water entry into the production wells.

Gravel pack resin treatments

Phenolic-resin plugback treatments were applied to 32 wells with openhole gravel pack completions in the Midway-Sunset field in 1987.[2] These resin treatments were reported to have decreased water production by 5,900 barrels of water per day (BWPD) and increased oil production by 256 barrels of oil per day (BOPD). Total revenue and savings from the resin treatments were estimated to be US $1 million, and the resin treatment project was reported to have paid out in 120 days. The phenolic resin treatments were applied successfully to downhole temperatures ranging from 100 to 200°F at this California cyclic-steam injection project.

Furan resin treatments in California

In 1980, Hess provided a brief review of 36 small-volume (1 to 5 bbl) furan resin treatments applied for a variety of purposes in California.[3] Of these 36 furan resin treatments, 27 were reported to have achieved "permanent" downhole plugging. The furan resin treatments were applied for a variety of purposes, including shutting off undesirable steam breakthrough in production wells, plugging thief zones in water and steam injection wells, shutting off bottomwater entry, and repairing casing and liner damage. The furan resin used in treating steam-stimulated and steamflood injection wells was reported to have held up through two years of service.

Epoxy resin treatment

A three-barrel epoxy resin treatment was applied to a Green Canyon production well in the Gulf of Mexico. The objective of this treatment was to shut off the lower perforated interval of the gravel-packed well. The temperature of the sand to be treated was 139°F. The wellbore had a deviation angle of 60° across the treated interval. The epoxy resin formula used was designed for a 4- to 6-hour pump time through coiled tubing and required a 24- to 48-hour shut-in time. Following the epoxy resin fluid-shutoff treatment, oil production increased from 240 BOPD before the resin job to 470 BOPD following the resin job. Following the resin treatment, the flowing tubing head pressure was reported to have increased dramatically.[4]

Steam injector profile correction

More than 40 crosslinked styrene-butadiene block copolymer resin/gel treatments of approximately four-barrel volume have been successfully applied as injection-well profile correction treatments in conjunction with the steamflood conducted at the Kern River field in California.[5] It was reported that none of the resin/gel treatments showed any steam entry into the treated wellbore intervals after the steam-shutoff resin treatments. Payout times for these resin steam-shutoff treatments, based on steam cost savings alone, were reported to have averaged less than two months. These resin/gel treatments were applied with conventional oilfield surface and downhole equipment.
