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

已发表: 09/03/2019

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.

背景

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.
