Provided Detailed Borehole Acoustic Image, Borehole Shape in OBM With High Solid Content
Objectives
Replace wireline that was not able to log the well due to the borehole conditions.
Obtain high-resolution borehole image data to identify fractures in a vertical well filled with 14.84 ppg (1.78 g/cc) oil-based mud (OBM).
Our Approach
Weatherford ran the UltraWave logging-while-drilling (LWD) ultrasonic imager. The logging suite included also a real time telemetry system, gamma ray, multi-frequency resistivity, and sonic tools.
The UltraWave imager made it possible to directly identify fractures and other features in the borehole in a hostile environment, made of oil-based, heavy mud with high concentration of solids.
Value to Customer
After replacing wireline, the Weatherford LWD tools were able to acquire gamma ray, resistivity, and sonic data together with high resolution amplitude images from the UltraWave imager for reservoir evaluation and completion planning.
