Noble Energy discovers additional pay at Katmai and Dantzler in deepwater Gulf of Mexico
HOUSTON -- Noble Energy has announced final well results at the Katmai exploration well and the Dantzler appraisal well in the deepwater Gulf of Mexico.
At Katmai, wireline logging data indicates a total of 154 net ft of crude oil pay was discovered in multiple reservoirs, including 117 net ft in Middle Miocene and 37 net ft in Lower Miocene reservoirs. The discovery well, located in Green Canyon 40, was drilled to a total depth of 27,900 ft in 2,100 ft of water. Total gross resources at Katmai are now estimated at between 40 and 100 MMboe, including 40 to 60 MMboe discovered from this initial well. Additional exploration and appraisal drilling will be required to test the remaining upside potential.
The Dantzler-2 appraisal well, located in Mississippi Canyon 782, encountered 122 net ft of crude oil pay in two high-quality Miocene reservoirs. The well was drilled to a total depth of 18,210 ft in 6,600 ft of water. Gross resources at Dantzler have increased to between 65 and 100 MMboe. Dantzler has been incorporated into the company' s plans in the Rio Grande development area, which also includes discoveries at Big Bend and Troubadour. The Rio Grande development remains on schedule, with first production from Big Bend expected in the fourth quarter of 2015 and Dantzler in the first quarter of 2016.
Susan M. Cunningham, Senior Vice President, Gulf of Mexico, West Africa, and Frontier, said, "What we discovered at Katmai represents another commercial discovery in the Miocene trend and de-risks nearby prospects in the company' s Aleutians area. Our appraisal program at Dantzler has exceeded our expectations and enhances the value of the development."
Noble Energy operates Katmai with a 50% working interest. Ridgewood Energy Corporation holds the remaining 50% working interest.
At Dantzler, the rig has started well completion operations on Dantzler-2 and will then complete the Dantzler-1 discovery well. Noble Energy operates Dantzler with a 45% working interest. Additional interest owners are entities managed by Ridgewood Energy with 35% and W&T Energy with 20%.
