摘要： A stand-alone frac liner that allows for fracturing of multiple lateral legs of a multilateral well on a single call out and rig-up of fracturing equipment. Tools and techniques are provided that include setting multiple stand-alone frac liners in multiple lateral legs of the multilateral well. The liners may rest in the legs physically untethered to surface equipment. Thus, a single call out of a frac string tubular and associated equipment may be used to frac the lateral legs in sequence from one leg to the next. This may be achieved without the requirement of removal of the tubular from the well or disconnect of surface fracturing equipment between the lateral fracture applications. Thus, a considerable amount of expenses associated with time and manpower may be saved.
摘要翻译：一个独立的压裂衬套，允许在单次呼出和压裂设备的装配时，将多边井的多个侧向柱断裂。提供了工具和技术，包括在多边井的多个横向腿部设置多个独立压裂衬套。内衬可能会搁置在身体不受地面设备束缚的腿部。因此，可以使用压裂串管状和相关联的设备中的单个呼出来从一个腿到另一个腿依次压裂侧腿。这可以在不需要从井中移除管或者在侧向裂缝应用之间切断表面压裂设备的情况下实现。因此，可以节省与时间和人力相关的大量费用。

摘要： A method of determining when to stop pumping proppant during hydraulic fracturing in a wellbore is described. By accurately detecting tip screen-out with a bottom hole pressure gauge mounted to a perforating gun, the optimal amount of proppant can be supplied to a fracture while avoiding the risks associated with wellbore screen-out.
摘要翻译：描述了一种在井筒中水力压裂期间确定何时停止泵送支撑剂的方法。通过用安装在穿孔枪上的底孔压力表精确检测尖端筛选，可以将最佳量的支撑剂供应到裂缝，同时避免与井眼筛选相关的风险。

摘要： Formation zones of interest may be isolated and stimulated by substantially instantaneously providing a pressure equal to or greater than the fracture pressure of the targeted zone. A treatment fluid is accumulated in coiled tubing until the pressure is equal to or greater than the fracture pressure of the targeted zone. The accumulated pressurized treatment fluid is released substantially instantaneously at the targeted formation zone. The accumulated pressurized treatment fluid may be substantially simultaneously released with the detonation of a perforation gun.

摘要： A method of treating a subterranean formation penetrated by a wellbore involves introducing an acid treatment fluid through the wellbore into the formation. The treatment fluid is formed from a zwitterionic viscoelastic surfactant, an acid in an amount to provide the treatment fluid with an initial pH of ≦0 and a rheology enhancer. The treatment fluid has a high viscosity at the initial pH and a lower viscosity when the pH of the treatment fluid is raised to an intermediate pH of from greater than 0 to about 5.
