摘要： A method of reclaiming a formate brine may include increasing the pH of a spent formate brine fluid comprising water-soluble polymers; treating the fluid with an oxidizing agent; and removing at least a portion of suspended solids from the fluid. Further, a method of reclaiming a formate brine may include lowering the pH of the spent formate brine fluid comprising water-soluble polymers; increasing the pH of the spent formate brine fluid to initiate precipitation of materials solubilized in the fluid; treating the fluid with an oxidizing agent to break down remaining water-soluble polymer; and recovering at least a portion of the formate brine.

摘要： A drilling fluid and method of using same. The drilling fluid comprises water as a continuous phase, an amount of calcium chloride, and a quantity of a polyacrylamide copolymer. The amount of calcium chloride and the quantity of polyacrylamide copolymer in the drilling fluid are sufficient to produce a rate of penetration approaching that achieved using a synthetic oil-based drilling fluid while preventing substantial screen blinding. In a preferred embodiment, the continuous phase also comprises a second amount of a monovalent salt effective to increase gas hydrate suppression and decrease density when compared to a fluid consisting essentially of only a divalent salt in the absence of the monovalent salt.
摘要翻译：钻井液及其使用方法。钻井液包括作为连续相的水，一定量的氯化钙和一定量的聚丙烯酰胺共聚物。钻井液中氯化钙的量和聚丙烯酰胺共聚物的量足以产生接近使用合成油基钻井液达到的渗透速率，同时防止大量的筛网堵塞。在一个优选的实施方案中，连续相还包含第二量的一价盐，当与不存在一价盐时基本上仅由二价盐组成的流体相比，这有效地增加气体水合物的抑制和降低密度。

摘要： A collapsible cart for carrying one or more golf bags while playing golf including a pair of large diameter wheels having an inflated pneumatic tire on each wheel and a foldable, lightweight, rigid frame of unique construction for positioning in a compact condition with folding of the frame between collapsed and extended positions enabling attachment and detachment of the independent wheels. The cart includes a unique U-shaped handle to facilitate movement of the cart by either pushing the cart or pulling the cart in the nature of a rickshaw. The handle is also pivotal for movement to a compact position alongside the frame. A pivotal bar is mounted on the frame to support the bottom portion of one or two golf bags and a tie cord is provided on the upper portion of the frame to retain the upper end portion of the bag or bags on the frame. Detachment of the frame from the wheels enables storage of the cart in relatively small spaces.
