Abstract
Oil field chemicals are incorporated in polymeric particles of the condensation product of hydroxyacetic acid or the co-condensation product of hydroxyacetic acid and other compounds containing hydroxy-, carboxylic acid-, or hydroxycarboxylic acid moieties. The particles are introduced into an oil well bore and/or subterranean oil formation where the polymeric particles dissolve over a period of time and release the oil field chemicals.
