摘要： An improved method for fracturing oil wells is disclosed and claimed herein. In particular, the present invention involves the determination of the direction of fracture propagation, i.e., perpendicular to the minimum stress existing within a given formation and the alignment of perforations produced by a variety of perforating devices with the previously determined direction of fracture propagation. The methods disclosed and claimed herein will eliminate many problems encountered in the prior art, including reducing the pressure required to initiate fractures and reducing the undesirable effects of near wellbore tortuosity.

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.
