This article describes simple and complex acoustic waves in the borehole. We examine propagation of compressional, shear, Stoneley and flexural waves in isotropic, anisotropic and inhomogeneous formations from monopole and dipole sources.

Sensitive oilfield detectors are helping scientists investigate the fundamental nature and origin of objects in outer space. In 1996, the Near Earth Asteroid Rendezvous spacecraft, or NEAR, equipped with oilfield sensors, left Earth for the asteroid 433 Eros, some 160 million miles away. In this article, we discuss the NEAR mission along with other examples that show how oilfield technologies are being used in the quest for knowledge and understanding of outer space.
