Rose Petroleum has spudded the State 1-34 Mancos well in Utah.
The company said it had used a smaller rig for better cost efficiency and will bring in a larger rig in early January to drill the balance of the well to total depth.
Surface casing will be set to 300 feet and once the surface casing is cemented in place, drilling operations will recommence.
Rose Petroleum said it plans to take the two whole cores across the Mancos formation in order to gather data to optimize the horizontal well and fracture system designs.
John Blair, director of Oil & Gas, said: “The spudding of our first Mancos well in less than a year from the initial acquisition of the assets is a tribute to the hard work and dedication of Rose’s staff and management and marks the first step in developing Mancos production on Rose’s leasehold, which is on target for H1 2015 as planned.”
Rose Petroleum owns 165,000 gross acres in the Mancos play in the Uinta Basin and ore than 245,000 acres collectively between the Uinta and the adjacent Paradox play.
