    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.

    Abstract translation: 提供了一种用于将流体从井下地层泵送到地球表面的容积式泵。 泵（100）首先包括柱塞（130）。 柱塞通过诸如潜水电泵的线性致动器（300）在井筒内轴向往复运动，以形成仰泳和仰泳。 泵入口（140）设置在柱塞的底端附近，而泵出口（150）设置在柱塞的顶端附近。 泵构造成使得其能够在泵的上行程期间在井眼内向上泵送第一体积的流体，并且在泵的下行程期间能够在井筒内向上泵送第二体积的流体。 因此，泵是“双作用”。

    Abstract: The present invention generally provides an apparatus and method for forming a pilot hole in a formation. The apparatus (100) comprises a starter mill (30) connected to a bearing mill (10) by a body joint (20). The apparatus may further comprise a lead bearing (50) connected to the starter mill by a lead joint (40). Preferably, an outer diameter of the bearing mill (10) is about the same as an inner diameter of a wellbore (4). As the lead bearing travels along the concave surface of a whipstock (8), the apparatus will bend between the bearing mill (10) and the lead bearing (50). The bend urges the starter mill (30) into contact with the wellbore wall. In another aspect of the present invention, a method for forming a pilot hole in a wellbore includes running a tool (100) into the wellbore, the tool comprising a starter mill (30) disposed between a first bearing (10) and a second bearing (50) . While running the tool along a concave of a whipstock, the tool bends between the first and second bearing and urges the starter mill to form the pilot hole.

    Abstract: A method of isolating a reservoir of production fluid in a formation comprises providing a pair of valves (14, 16) in a bore intersecting a production formation and in which the hydrostatic pressuer in the bore at the formation is normally lower than the formation pressure, and then ontrolling the valves (14, 16) from surface such that the valves (14, 16) will only move from a closed configuration to an open configuration on experiencing a predetermined differential pressure across the valves.
