Seismic-Guided Drilling Service

Optimize well placement in real time

Drill safer, more cost-effective wells

Geomechanical-related problems during the drilling phase can have a significant effect on drilling safety and well cost. Our seismic-guided drilling service helps you avoid costly drilling risks by predicting geohazards and pore pressure ahead of the bit using real-time well data.

Rebuild models while drilling

Seismic-guided drilling integrates surface seismic and downhole measurements simultaneously while drilling to identify geological and geomechanical complexities. It uses the most accurate model available to help you plan your well design and avoid drilling hazards that may not be apparent until you reach a certain depth.

Our seismic-guided drilling service is a powerful application of a fast, integrated, and iterative workflow.

Step 1
Start with a baseline fit-for-purpose 3D predrill model including velocities, a structural image, and pore pressures.
Step 2
Acquire well data while drilling including sonic logs, checkshots, and well tops.
Step 3
Update the shallow velocity model behind the bit with the measured velocities.
Step 4
Update the velocity model ahead of the bit to match the seismic data.
Step 5
Repeat the workflow until target depth is reached.
