摘要： There is provided a wellbore fluid having a continuous aqueous phase, and comprising at least one polymer which contains both hydrophilic units and hydrophobic units, at least some of said hydrophilic units containing sulfonate groups, and less than 50 % by weight of said hydrophilic units comprising -CH 2 .CH 2 .O- units; and at least some of said hydrophobic units containing pendant alkyl groups having at least 8 carbon atoms. Such aqueous based wellbore fluids exhibit significantly improved fluid loss properties when used in wellbore operations, such as drilling, completion or workover.

摘要： A process for deacidifying a crude oil and/or crude oil distillate containing organic acids the steps of (a) contacting the oil containing organic acids with a polar solvent comprising a C1 to C6 aliphatic alcohol in the presence of a Group IA and/or Group IIA metal salt selected from the group consisting of Group IA and/or Group IIA metal oxides, hydroxides and alkoxides such that at least a portion of the organic acids are converted into Group IA and/or Group IIA neutralization salts thereof and at least a portion of the neutralization salts are extracted into the polar solvent as an extract phase; (b) separating an oil phase which is reduced in acidity from the polar solvent extract phase; and (c) contacting the polar solvent extract phase with a heterogeneous esterification catalyst under condition effective to convert at least a portion of the Group IA and/or Group IIA neutralization salts to the corresponding esters of the organic acids and the C1 to C6 aliphatic alcohol.
摘要翻译：一种使含有有机酸的原油和/或原油馏出物脱酸的方法，包括以下步骤：（a）使含有油的有机酸与包含C1-C6脂族醇的极性溶剂在IA族和/或组的存在下接触选自IA族和/或IIA族金属氧化物，氢氧化物和醇盐的IIA族金属盐，使得至少一部分有机酸转化为IA族和/或IIA族中和盐和至少一部分的中和盐作为提取相被提取到极性溶剂中; （b）从极性溶剂萃取相中分离出酸度降低的油相; （c）使极性溶剂萃取相与非均相酯化催化剂在有效将至少一部分IA族和/或IIA族中和盐转化为相应的有机酸酯和C1-C6脂族醇的条件下接触。
