Abstract
A method of chemical injection and of swabbing and/or flow testing a subterranean well by interconnecting a resettable packer and a circulating wash tool so that the packer may be positioned and set in the casing at a plurality of positions above the casing perforations. The introduction of pressurized chemical solution through the tubular work string produces an injection of the chemical solution into the perforations isolated by the vertically spaced annular sealing elements conventionally provided on the wash tool. Following the chemical treatment, the wash tool can be moved to a position above the perforations and a swab test run to measure the productive capabilities of the treated formation, all with a single trip of the wash tool and associated packer into the well.
