摘要： A system and method is provided for minimizing lost circulation associated with the operation of a subterranean reservoir. The system includes one or more sources, such as earth modeling and fracture analysis tools, for providing data representative of a fracture formation in the reservoir, and a computer processor in communication with the data sources for determining an appropriate blend of lost circulation material products for application to the fracture formation. The computer processor is programmed with computer readable code for selecting a plurality of candidate products for application to the fracture formation, and for mathematically determining an optimized blend of the selected products. By applying the optimized blend, material and labor costs associated with well operation can be significantly reduced.

摘要： Generally, the present invention is directed to the in situ measurement of fluid density and/or flow rate in tubular conduits, wherein such measurement comprises measuring dynamic fluid level and/or load (weight) in a region of the conduit and correlating these measurements of the fluid with a density and/or flow rate. Such measurements are typically directed toward drilling fluids transported within the tubular conduits—particularly the return flow, wherein the fluid comprises extraneous material (e.g., cuttings, etc.) which can alter the density and flow rate of the drilling fluid.
摘要翻译：通常，本发明涉及在管状管道中的流体密度和/或流速的原位测量，其中这种测量包括测量导管区域中的动态流体水平和/或载荷（重量），并将这些测量值具有密度和/或流速的流体。这种测量通常针对在管状管道内输送的钻井流体，特别是返回流，其中流体包括可以改变钻井液的密度和流速的外来材料（例如切屑等）。

摘要： A process to substantially reduce fluid loss in which an appropriate amount of a non-flowing gel of sufficient strength is emplaced to substantially eliminate or reduce loss of the drilling fluid. The gel composition of the process includes: (1) a non-cellulose containing copolymer having vinyl phosphonate co-monomer units which may be incorporated into the polymer by copolymerization with the other co-monomer(s) comprising the polymer or by grafting upon an already existing polymer or co-polymer, (2) a crosslinking agent active upon the phosphonate groups, (3) a crosslinking initiator comprising a Bronsted Lowry base or Lewis base and (4) an aqueous solvent.
