Abstract
A formation pressure testing while drilling device on a bottomhole assembly makes measurements of fluid pressure during drilling of a borehole. Based on the pressure measurements, drilling direction can be altered to maintain the wellbore in a desired relation to a fluid contact. Acoustic transmitters and/or receivers on the bottomhole assembly can provide additional information about bed boundaries, faults and gas-water contacts.
