Abstract
Methods and apparatus for communicating between a MWD or LWD logging tool and a surface processor, such as a PC, using a high speed transmission control protocol-internet protocol (TCP-IP) based connection link. Logging tool sensor response is stored in memory within the tool while logging. The link is removably attached to a data port in the tool when the tool is subsequently removed from the borehole. Stored sensor response information is transferred very rapidly from tool memory as TCP-IP data packets. Transmission is two-way thereby allowing commands to be transmitted from the PC to the tool for control of the tool and the data acquisition function of the tool. The two-way data transmission function can be performed at one or more PC's remote from a drilling rig using a commercially available TCP-IP hub and the internet.
