Abstract: A downhole motor control system may identify a downhole compressible density of a drilling fluid using a downhole temperature and a downhole pressure of the drilling fluid, the drilling fluid including an incompressible portion and a compressible portion, the drilling fluid flowing downhole with a downhole compressible flow component and an incompressible flow component. A downhole motor control system may determine the downhole compressible flow component using the downhole compressible density, a surface compressible density of the compressible portion at a surface location, and a surface compressible flow component of the compressible portion at the surface location. A downhole motor control system may identify a downhole compressible fraction of the drilling fluid based on the downhole compressible flow component and the incompressible flow component.

Abstract: A computer-aided engineering (CAE) toolkit is disclosed that streamlines and automates aspects of a CAE simulation to validate the designs of pressure-controlling components, such as BOP rams. The CAE toolkit enables a designer to provide a model of a pressure-controlling component, and to provide property values that describe aspects of the system to be modeled. Based on these inputs, the CAE toolkit generates a model for the system that includes the pressure-controlling component, as well as any other components that will be part of the simulation. The CAE toolkit can automatically generate a finite element analysis (FEA) model from the system model, and then use the FEA model to perform a simulation of the pressure-controlling component during operation. The CAE toolkit enables a designer with no training or experience with CAE or FEA techniques to perform and automate simulations of the operation of a pressure-controlling component design.

Abstract: A downhole tool includes a body having a bore extending at least partially therethrough. A component is disposed within the bore and arranged and designed to move axially from a first position to a second position within the bore. An axial end portion of the component has a first contact surface that is oriented at an angle from about 1° to about 45° with respect to a longitudinal axis extending through the component.
