摘要： A method of stimulating a downhole formation according to which a plurality of jet nozzles are located in a spaced relation to the wall of the formation to form an annulus between the nozzles and the formation. An acid-containing, stimulation fluid is pumped at a predetermined pressure through the nozzles, into the annulus and against the wall of the formation. A gas is pumped into the annulus so that the stimulation fluid mixes with the gas to generate foam before the mixture is jetted towards the formation to impact the wall of the formation.

摘要： An orbital downhole separator for separating well fluids into constituents of different specific gravities. Specifically, it is designed to separate water from oil or gas. The apparatus comprises a housing with a rotating member therein driven by a motor in the housing. Well fluid flows through the rotating member and is subjected to centrifugal force to separate the components. A flow conditioner is used to facilitate separation. The invention includes several different versions of the flow conditioner including an impeller, a stator and controllers for controlling the speed of the motor in response to signals related to the amount of petroleum in the water.

摘要： Systems and methods for reducing the amount of torque transferred to the Bottom Hole Assembly and the drill string during drilling operations are disclosed. The drill string includes an optionally non-rotatable portion. A rotational hold down system is positioned at a first position on the drill string where it is not rotationally coupled to the drill string. The rotational hold down system is then moved to a second position on the drill string where it is rotationally coupled to the optionally non-rotatable portion of the drill string. In the second position, one or more bars on the rotational hold down system substantially prevent rotation of the optionally non-rotatable portion of the drill string.
