Otto Energy said June 13 the upper DTR-10 target of the Talos Energy-operated Bulleit oil appraisal well in the U.S. Gulf of Mexico has been confirmed as commercial.

“The petrophysical evaluation of the DTR-10 sands have confirmed a new commercial discovery, with excellent rock properties and high quality oil,” Matthew Allen, managing director for Otto, said in a statement. “Upon the conclusion of the drilling operations, the well will be suspended as a future producer, with completion and hook-up operations in 2020.”

The current development plan is a subsea tieback to the Talos-operated Green Canyon 18 platform.

Drilling to test the deeper MP sand requires a sidetrack around a compromised hole section, Otto added. Sidetrack operations are expected to take about seven days to drill and cement 11 7/8-in. liner in the new hole solution. Drilling from the liner to total depth is expected to take another 15 days, the company said.

Talos holds a 50% interest in Green Canyon 21, where Bulleit is located. Otto holds 16.67%, while EnVen Energy Ventures holds 33.33%.
