Physics in Oil Exploration

Petroleum engineers use a variety of physical techniques to find and exploit petroleum reservoirs in increasingly remote and complicated geological environments.

Electromagnetic Propagation Logging While Drilling: Theory and Experiment

Presentation of the Compensated Dual Resistivity (CDR) tool, electromagnetic propagation tool for measurement while drilling. The CDR provides two resistivity measurements with several novel features that are verified with theoritical modeling, test-tank experiments, and log examples.

Microinduction Sensor for the Oil-Based Mud Dipmeter

Microinduction sensors are used in the Oil-Based Mud Dipmeter Tool to measure formation conductivity through nonconductive mud or mudcake. The sensor consists of small transmitter and receiver coils mounted in a pad. An extensive research effort involving sensor response modeling, laboratory experiments, and signal processing contributed to the development of these new sensors.
