High-Definition Visualization of Complex and Fractured Clastics While Drilling in Oil-Based Mud

Published: 09/03/2019

Concrete blue texture
Highresolution resistivity and ultrasonic images
The TerraSphere service successfully acquired high-resolution resistivity and ultrasonic images in this challenging environment. The interpretation of information gathered by the TerraSphere service’s electromagnetic and ultrasonic technologies highlights faults and fracture orientations, layer bedding details, cross bedding, and irregular surfaces. Data acquisition while drilling enables detailed imaging of the coal layers and early breakout phases.

Operator
Aker BP

Background

Aker BP needed high-definition images while drilling a sidetrack offshore. This well was expected to run through a complex clastic shallow marine and fluvial sequence. Delineation of the expected thin and variable interbeds of sandstones, claystones, and coals in oil-based mud is challenging with conventional LWD tools. Consequently, Aker BP chose to run the TerraSphere service to characterize the formations.
