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.

Computer-aided engineering toolkit for simulated testing of pressure-controlling component designs

A method to create a simulation of a shearing process for a ram blowout preventer (BOP) comprising the steps of building a 3D digital model of the ram BOP including damage parameters based on generic material properties of the ram BOP; inputting the 3D digital model of the ram BOP into a damage model; and simulating the shearing process using the 3D digital model of the ram BOP and the damage model.

Method to simulate bop shearing

A method can include receiving data acquired via a sensor of a component of a plurality of components arranged in an order at respective axial positions of a toolstring; analyzing at least a portion of the data with respect to a model of the toolstring to generate results; and controlling the toolstring based at least in part on the results.

Drilling assessment system

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&#xb0; to about 45&#xb0; with respect to a longitudinal axis extending through the component.
