摘要： The gap sub assembly comprises a pair of electrically conductive subs. Each sub has a threaded pin and box. A pin and box are threaded together to form a connection. An electrically insulating, woven fabric overlies and conforms with the threads of the connection pin. An electrically insulating, annular washer separates the seal faces of the connection. The assembly functions to provide an electrical discontinuity when incorporated into a conductive drill string.

摘要： A computational geometry server is provided that includes a server, a communication link, at least one client, and an interrupt interface. The server has processing circuitry and an operation manager. The operation manager is configured to compare source geometric data in a source geometric model with target geometric data in a target geometric model. Furthermore, the operation manager is operative to identify discrepancies in the geometric data between the source geometric data and the target geometric data. The at least one client communicates with the server over the communication link. The interrupt interface is operative to notify a user of the presence of an inability to automatically generate an accurate representation of the source geometric model in the target geometric model. A method is also provided.
