Noble Energy announced successful results for the Katmai exploration well and the Dantzler-2 appraisal well in the deepwater Gulf of Mexico.
Katmai exploration well
Noble is reporting great news at Katmai with total gross resources for the well estimated between 40 and 100MMboe, including 40 to 60MMboe discovered from the initial well. Katmai is located in Green Canyon 40 and was drilled to a total depth of 27,900ft in 2100ft water depth. Wireline logging data indicated a total of 154 net ft of crude oil pay discovered in multiple reservoirs, including 117 net ft in Middle Miocene and 37 net ft in Lower Miocene reservoirs.
Noble says additional exploration and appraisal drilling is required to test the remaining upside potential.
Noble Energy operates Katmai with a 50% interest with partner Ridgewood Energy Corp. (50%).
Dantzler appraisal well
The Dantzler-2 appraisal well, located in Mississippi Canyon 782, encountered 122 net ft of crude oil pay in two high-quality Miocene reservoirs. Gross resources have increased to between 65 and 100MMboe. The well was drilled to a total depth of 18,210ft in 6600ft of water.
Noble has incorporated Dantzler into its plans in the Rio Grande development area, which includes discoveries at Big Bend and Troubadour. The development remains on schedule, with first production from Big Bend expected in the 4Q 2015 and Dantzler in the 1Q 2016.
The ENSCO 8501 righas begun well completion operations on Dantzler-2 and will then move to complete the Dantzler-1 discovery well.
Noble operates Dantzler with a 45% interest. Partners include Ridgewood Energy (35%) and W&T Energy VI, LLC (20%).
"The results at Katmai and Dantzler highlight Noble Energy's successful deepwater Gulf of Mexico program, which will contribute significant production and cash flow growth in the coming years,” says Susan M. Cunningham, senior VP, Gulf of Mexico, West Africa, and Frontier. “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."
In addition to Big Bend and Troubadour, Noble also has the Gunflint project in the Gulf of Mexico. Noble says that these fields combined are planned to double their deepwater Gulf of Mexico production over the next four to five years.
Earlier this month, Noble’s Bright exploration well located on the Atwater Valley 362 in the deepwater Gulf of Mexico did not encounter hydrocarbons. The well was plugged and abandoned. Noble acquired 17 deepwater exploration licenses in Atwater Valley in June 2014 with partner BP Exploration and Production Inc.
