摘要： An improved method and apparatus are provided for orienting a particular well completion in accordance with azimuths determined with respect to magnetic north. The invention permits the perforating gun of a wireline tool to be properly oriented in either a vertical or non-vertical wellbore. A wireline tool is described whose lower section contains a gun section and is rotatably joined to the upper section and may be rotated about a swivel joint assembly to move independently of the upper section and in accordance with an orienting means. The rotation may be accomplished by mechanical, hydraulic or electrical means of imparting rotation. In addition, preferred embodiments of the invention include a distant display such that operators may verify directional orientation of charges prior to initiating them. Alternative embodiments are provided for practicing the invention using multiple passes into the well which involve less risk of damage to portions of the well tool.

摘要： Methods for stimulating a high-permeability subterranean formation are disclosed. In one embodiment, a method comprises the step of selecting a target fracture geometry for a portion of a subterranean formation. The method further comprises the step of introducing a pad fluid comprising a fluid-loss-control additive into the portion of the subterranean formation to create or extend one or more fractures in the portion of the subterranean formation, wherein an amount of the fluid-loss-control additive is determined based at least in part on the target fracture geometry. The method further comprises allowing a barrier to form along at least a portion of the one or more fractures, wherein the barrier comprises the fluid-loss-control additive. The method further comprises introducing a slurry fluid comprising proppant particulates into the one or more fractures, wherein a tip screen-out occurs in at least one of the one or more fractures.
