Title
(EN) SYSTEM AND METHOD FOR INHIBITING SCALE FORMATION IN OIL WELLS
(FR) SYSTÈME ET PROCÉDÉ D'INHIBITION DE FORMATION DE DÉPÔTS DANS DES PUITS DE PÉTROLE
Abstract
(EN)
An illustrative method of reducing an amount of treatment water injected into a subterranean well may include providing an environmentally friendly polymer, such as a biodegradable polymer (e.g., an aspartic acid based polymer), to the subterranean well. In some cases, the aspartic acid based polymer may include one or more of a copolymer of the aspartic acid based polymer, a terpolymer of the aspartic acid based polymer, an aspartic acid based polymer derivative, an aspartic acid based polymer having an end cap, and a soluble salt of the aspartic acid based polymer. In some cases, the treatment water use may be reduced within the range of about five percent to about ninety five percent.
(FR)
L'invention concerne un procédé illustratif de réduction d'une quantité d'eau de traitement injectée dans un puits souterrain qui peut comprendre la fourniture d'un polymère respectueux de l'environnement, tel qu'un polymère biodégradable (par exemple, un polymère à base d'acide aspartique), au puits souterrain. Dans certains cas, le polymère à base d'acide aspartique peut comprendre un ou plusieurs d'un copolymère du polymère à base d'acide aspartique, d'un terpolymère du polymère à base d'acide aspartique, d'un dérivé du polymère à base d'acide aspartique, d'un polymère à base d'acide aspartique ayant une coiffe d'extrémité et d'un sel soluble du polymère à base d'acide aspartique. Dans certains cas, l'utilisation d'eau de traitement peut être réduite dans la plage d'environ cinq pour cent à environ quatre-vingtquinze pour cent.
