Formation Dip in Wells with Nonconductive Mud
The OBDT oil-base dipmeter tool uses four microinduction sensors to measure the variation of formation conductivity. The combination of a three-axis accelerometer and three-axis magnetometer precisely measures borehole drift and tool attitude. Dip processing eliminates tool velocity fluctuations, and application of the induction measurement principle avoids the erratic influence of nonconductive mud on the injection of current into the formation.
The OBDT log can be recorded in a single pass to save rig time. Wellsite processing provides formation dip, hole diameter, and inclinometer data. Structural and stratigraphic information are available through processing.
