Abstract: A whipstock (100) is attached to a cutting tool (120) by a shearable connection (405, 410) whereby the whipstock and cutting tool assembly may be run into the wellbore simultaneously. Upon compressive force from above, the shearable connection fails and the cutting action can begin. The shearable connection (405, 410) is designed to fail in compression but to withstand forces in tension brought about by the whipstock, accessories and extensions required to properly place the whipstock above a preset packer in the wellbore.      In one aspect, the shearable connection means provides a first set of shearable members (410) with equal shear resistance in tension and in compression. Another set of shearable members (405) provide shear resistance against tensile forces but do not provide shear resistance against compressive forces. Failure of the connection due to the weight of the whipstock assembly is less likely.

Abstract: A positive displacement pump for pumping fluids from a downhole formation to the earth's surface is provided. The pump (100) first comprises a plunger (130). The plunger is reciprocated axially within the wellbore by a linear actuator (300), such as a submersible electrical pump, in order to form an upstroke and a downstroke. A pump inlet (140) is disposed near the bottom end of the plunger, while a pump outlet (150) is disposed near the top end of the plunger. The pump is configured such that it is able to pump a first volume of fluid upward within the wellbore during the pump's upstroke, and a second volume of fluid upward within the wellbore during the pump's downstroke. Thus, the pump is "double-acting", that is, it is able to displace fluids both on the downstroke and on the upstroke. The pump also permits the capture of a greater volume of fluids without a corresponding increase in velocity of the fluids through the pump. Furthermore, the pump is substantially hydrostatically balanced.

Granted: 2009-09-15
Abstract: In this invention there is provided a pouring vessel of the squeezable, delaminated bottle type, which can be squeezed smoothly to the last moment of discharge operation so that little content remains in the vessel. The vessel or container of a delaminated bottle type comprises the outer shell layer that forms a squeezable outer container and the inner layer that forms an inner container for receiving its content inside and capable of being deflated and deformed inward with the decrease in inner pressure; and the container is also provided with a discharge cap. In this configuration, a pair of vertically extending adhesive resin strips is formed by adhering the outer shell layer and the inner layer over the roughly entire height of the container. The relationship of the peripheral length between the two adhesive resin strips to the width of each strip is determined to give such a range that the inner container can be almost completely deflated and deformed. In the case of the container having the body of an elliptical shape, the adhesive resin strips are disposed at both ends of the long axis of the body, axisymmetrically on the central axis, with each strip being divided by the long axis into right and left parts having different lengths in the width direction.
