Abstract: A downhole tool includes a hydraulically operated actuation device to actuate the downhole tool and a control system that regulates flow of hydraulic fluid to the actuation device. The control system includes a pilot module and a power module. The power module has a first solenoid valve and a second solenoid valve fluidly coupled to a pressure source and a fluid return. The power module is fluidly coupled to the actuation device at an output line and a power line. A first power module check valve is arranged in the power line, a second power module check valve is arranged in a control pressure return line fluidly coupled to the fluid return, a first input communicates with the first solenoid valve, and a second input communicates with the second solenoid valve. A pilot-operated check valve is actuatable in response to a pilot signal to drain hydraulic fluid from the power module.

Abstract: A method includes conveying a casing cutting tool into the wellbore lined with at least one casing string and cement, and stroking the casing cutting tool over a predetermined axial length of the wellbore while ejecting fluid from one or more nozzles in the casing cutting tool and thereby forming a plurality of longitudinal cuts through the casing string and cement. The casing cutting tool is then rotated about its longitudinal axis at two or more axially offset locations along the predetermined axial length while ejecting fluid from nozzles and thereby forming a plurality of axially offset transverse cuts in the casing string and the cement. The longitudinal cuts and axially offset transverse cuts form wedges in the wellbore, and the wedges are dislodged from the wellbore to expose formation rock along the predetermined axial length.

Abstract: An insert for a golf bag having a generally open top and a generally closed bottom includes a golf club supporting structure in the bag. The insert also includes a compartment for each club. A closure structure is included at the generally open top of the bag and includes an opening for each compartment and a closure member having deflectable closure sections adjacent to each opening at the top of each compartment for each club. A movable tab included in the tubular compartment is deflected by a golf club inserted into the tubular compartment, the deflection is resisted by a cylindrical sheath surrounding the tubular compartment, thereby applying a holding force to the golf club.

Abstract: An apparatus for securing and using hydrajetting tools within a borehole includes a housing that defines an inner bore. A flow limiting member may be disposed within the inner bore. The flow limiting member may include a first a first jet in fluid communication with the top of the housing, a first chamber positioned below and in fluid communication with the first jet, and a first cavity aligned with the first jet and in fluid communication with the chamber. A groove may be disposed on an outer surface of the housing, with an anchor assembly that is disposed around the housing and axially slidable and securable within the groove.

Abstract: A diverter for a subterranean well, a diverter retrieving tool and methods of diverting objects traversing the well and retrieving the diverter. The diverter comprises: (1) a body having a lower portion adapted to be coupled to a diverter anchoring structure and an upper portion having a slanted diverting surface, the diverter adapted to be placed within a main borehole of the subterranean well at a predetermined location and orientation proximate a junction of a lateral borehole with the main borehole, the slanted diverting surface adapted to redirect an object having a particular diameter and coming into contact with the diverter into the lateral borehole and (2) a compliant spring member associated with the slanted diverter surface.

Abstract: Debranched amylopectin and debranched low-DE maltodextrin have been found to cause protein to aggregate in solution. Such aggregation, which can lead to precipitation or flocculation of the protein, is useful for instance in aerated aqueous fat emulsions, e.g. ice cream and whipped cream, where the stability of the product can be altered as desired.
