A composition is formed from a polymeric acid precursor, such as polylactic acid (PLA), that is a least partially dissolved within a polymer dispersing solvent. An emulsion may be from polymeric acid precursor that is at least partially dissolved within a solvent and a liquid that is substantially immiscible with the solvent. In certain cases, the molecular weight of the polymeric acid precursor may be reduced in forming the solution. The solution may be used in treating a formation penetrated by a wellbore.

Une composition est formée à partir d'un précurseur d'acide polymère, tel que l'acide polylactique (PLA), au moins partiellement dissous dans un solvant de dispersion polymère. Une émulsion peut être formée à partir d'un précurseur d'acide polymère au moins partiellement dissous dans un solvant et d'un liquide sensiblement non miscible avec le solvant. Dans certains cas, la masse moléculaire du précurseur d'acide polymère peut être réduite en formant la solution. La solution peut être utilisée dans le traitement d'une formation pénétrée par un trou de forage.
