Petrel Drilling

Integrated well path design in a shared earth model to maximize reservoir contact, avoid hazards, select optimum mud weight, and manage risk.

A breakthrough sol​ution for drilling engineers and geoscientists

Applying geological knowledge to drilling workflows works best when drilling and subsurface teams share a common understanding. The Petrel E&P software platform provides a common canvas for a shared earth model in the reservoir and the overburden. Drilling engineers and geoscientists can now work together to evaluate more challenging exploration and development scenarios.

In today’s challenging environments—regardless of tougher regulations or demanding reservoir locations—you can work with more confidence, from the initial screening step to the more rigorous analysis. Ultimately, these workflows improve the life cycle, whether in the well planning phase, during drilling operations, or in post-well reviews.

Well path design and positioning 

Within the Petrel E&P software platform, geoscientists can propose targets based on features within the geological model, and drilling engineers can design single or multiple well paths to position the well accurately in the zone of interest. By capturing and displaying events and risks encountered while drilling previous wells, you can avoid the hazard zones while planning the well.

Pad and well placement can be optimized based on various geological and geographical constraints. Real-time monitoring of the well being drilled enables rapid updating of the model, and therefore the planned well, to eliminate or minimize potential risks ahead and to maximize reservoir exposure.

After your wells are planned, you can fine-tune the attributes. Wells plans can be adjusted for cost, directional complexity, and platform locations, while the best-fit workflow ensures maximum reservoir contact. You can view all changes in a geological context within a 3D window.

Within the well positioning workflow, a full anticollision analysis in a shared earth model context enables you to visualize critical results. This is especially useful in congested offshore or land development environments.

Relief well simulation

The Drillbench Blowout Control simulator—powered by the OLGA multiphase simulator technology—in the Petrel platform gives drilling engineers and well control specialists a powerful, accurate, and reliable tool for planning and analyzing relief wells. The relief well plan validation can be made at the design stage, with rapid evaluation of uncertainty within the parameters. Updates can be made at any time—whether prior to drilling, during drilling, or in post-well reviews.
