    • Water injection wells are fractured by a proppant-laden fracturing fluid to create a propped fracture and wherein the proppant-laden fluid is followed by injection of a substantially proppant-free fluid so that the near wellbore portion of the fracture is free of proppant to minimize pressure drop during water injection and to produce higher injection rates for a given injection pressure. The fracture treatment may include the use of viscous fracturing and displacement fluids which are degraded by the injection of acid-bearing fluids at the end of the fracture treatment cycle. Stimulation or displacement liquid (water) injection may commence immediately after the fracture treatment and may be alternated with miscible gas injection.
    • 注水井被支撑剂负荷的压裂液破裂以产生支撑的断裂,其中载持支撑剂的流体之后是注入基本上不含支撑剂的流体,使得裂缝的近井筒部分不含支撑剂以最小化 在注水期间的压降以及为给定的注射压力产生较高的注射速率。 断裂处理可以包括使用在断裂处理循环结束时通过注入含酸流体而降解的粘性压裂和置换流体。 刺激或置换液体(水)注射可以在断裂处理后立即开始,并且可以与混溶气体注入交替。

    • Fractures are initiated or extended within an earth formation from a well which includes a tubing string extending to a wellbore space adjacent the fracture zone from a conventional wellhead. Carbon dioxide, nitrogen or a similar highly expansible fluid is pumped into the wellbore space and/or at least a portion of the tubing string at a pressure greater than the fluid critical pressure and greater than the fracture initiation or extension pressure required in the formation zone. A perforating gun is fired or a shear disk is actuated to release the expansible fluid to flow into the formation at an initial velocity and kinetic energy which substantially exceeds that which is obtained with water or similar conventional fracturing fluids so as to initiate or extend hydraulic fractures with a minimum radius of curvature with respect to the wellbore.

    • Method, apparatus, and program means for performing a packed multiply high with round and shift operation. The method of one embodiment comprises receiving a first operand having a first set of L data elements. A second operand having a second set of L data elements is received. L pairs of data elements are multiplied together to generate a set of L products. Each of the L pairs includes a first data element from the first set of L data element and a second data element from a corresponding data element position of the second set of L data elements. Each of the L products are rounded to generate L rounded values. Each of said L rounded values are scaled to generate L scaled values. Each of the L scaled values are truncated for storage at a destination. Each truncated value is to be stored at a data element position corresponding to its pair of data elements.

    • A rotary viscometer includes a rotor member having plural helically staggered mixing blades disposed on the outer surface thereof for thoroughly mixing a quantity of fluid whose viscosity is being measuring during rotation of the rotor member. The viscometer has a relatively large annular space between the rotor member and a stationary bob member, and the viscosity of hydraulic fracturing fluids for earth formations, in particular, of a type which exhibit increased viscosity at elevated temperatures, is measured by an improved method using the viscometer.
