摘要： A method of optimizing performance of a well system utilizes a neural network. In a described embodiment, the method includes the step of accumulating data indicative of the performance of the well system in response to variable influencing parameters. The data is used to train a neural network to model an output of the well system in response to the influencing parameters. An output of the neural network may then be input to a valuing model, e.g., to permit optimization of a value of the well system. The optimization process yields a set of prospective influencing parameters which may be incorporated into the well system to maximize its value.

摘要： A motor and rotor catch assembly for preventing loss of broken motor parts downhole. The assembly comprises a motor including a rotor supported inside a stator housing. A rotor bolt is connected to the upper end of the rotor, and is supported for axial movement within a rotor bolt housing from a running position to a deployed position. If the stator housing breaks or backs off, the attached rotor bolt shifts to the deployed position. In the deployed position, the bolt substantially reduces flow to the stator housing and simultaneously opens bypass ports to vent fluid to the annulus instead. In this way, the rotor is prevented from spinning rapidly, the diverted fluid creates a pressure change that alerts the operator to the motor failure, and the diverted fluid allows continued removal of debris and cuttings from the well bore.

摘要： A hydraulic jar for delivering impacts downhole. The jarring mechanism includes a cup-type piston that moves through a seal bore. The cup is deformable in response to fluid pressure so that it expands each time it moves through the seal bore to compensate for wear on the lip. Since only minimum interference is required between the piston and seal bore, less material may be used. This reduces the force required to reset the tool, which is particularly advantageous in horizontal wells. The seal bore may be slightly wider at the exit; the cup expands to this exit diameter, ensuring an interference fit as the cup travels back through the smaller diameter entry section. The entry end of the seal bore may include longitudinal grooves. This prevents the piston cup from rupturing by preventing a fluid seal around the lip until the most of cup is inside the seal bore.
摘要翻译：用于在井下输送冲击的液压罐。振动机构包括移动穿过密封孔的杯形活塞。杯子响应于流体压力而变形，使得其每次穿过密封孔时都会膨胀，以补偿唇缘上的磨损。由于在活塞和密封孔之间只需要最小的干扰，所以可以使用更少的材料。这减少了重置工具所需的力，这在水平井中是特别有利的。密封孔可以在出口处稍宽一些; 杯子膨胀到该出口直径，确保当杯子通过较小直径入口部分返回时过盈配合。密封孔的进入端可以包括纵向凹槽。这防止活塞杯通过防止围绕唇缘的流体密封而破裂，直到杯的大部分位于密封孔内。
