Abstract: Hydroxyethylcellulose (HEG) may be used to provide fluid-loss control in well-cement slurries HECs that have a molecular weight above 600,000, a degree of substitution higher than 1.9 and a molar substitution above 2.0 are particularly useful in that they not only provide fluid-loss control, but also may be used as a cement extender. Furthermore, the retardation effect may be reduced.

Abstract: The current application discloses methods and systems to analyze on-site and in real-time or quasi real-time the composition of the well fluid before or during use or disposition. The method is based on capillary electrophoresis (CE) and does not require the addition of tracers into the well fluid or additive. Based on the significance of each additive on the well fluid properties, it can be decided to determine the concentration of all additives or only one or a limited number of the additives present in the fluid, and the concentrations can be adjusted as needed to reach the desired target concentration(s).
Abstract translation: 目前的应用公开了在现场和实时或准实时分析井流体在使用或处置之前或期间的组成的方法和系统。 该方法基于毛细管电泳（CE），并且不需要向井液或添加剂中添加示踪剂。 基于每种添加剂对井液性质的重要性，可以决定确定所有添加剂的浓度或只有一种或有限数量的存在于流体中的添加剂，并且可以根据需要调整浓度以达到 所需目标浓度。

Abstract: A cement slurry composition is described as having cement, water, and organic polymer particles. The composition also includes non-ionic surfactants, which may contain ethoxylate groups or contain both ethoxylate groups and propoxylate groups in the hydrophilic part. The non-ionic surfactant acts to disperse the hydrophobic polymeric particles in the slurry, thereby reducing mixing time. The cement slurry composition is prepared and then pumped into the subterranean well and placed in a zone of the subterranean well. Time is then allowed for the cement slurry composition to set and form a solid mass in the zone.
Abstract translation: 水泥浆组合物被描述为具有水泥，水和有机聚合物颗粒。 组合物还包括非离子表面活性剂，其可以在亲水部分中含有乙氧基化物基团或含有乙氧基化物基团和丙氧基化物基团。 非离子表面活性剂用于将疏水性聚合物颗粒分散在浆料中，从而减少混合时间。 制备水泥浆组合物，然后泵送到地下井中并置于地下井的一个区域中。 然后允许水泥浆料组合物在该区域中固化和形成固体物质。
