Cinnabar-1 well flows Oil and Gas
Mosman Oil and Gas Limited (AIM: MSMN) the oil exploration, development, and production company, provides an update in respect to the Cinnabar-1 well in Tyler County, Texas. The Cinnabar well was drilled in October 2022 and is now in the process of being completed and placed on production.
The well has been completed and perforated in the upper Wilcox zone (9,050 to 9,110 feet). Initial flow is both oil and gas.
The well has been flowing into temporary tankage which is volume constrained. The next step is to connect the well to the existing production facility with larger tanks and gas separation. This will allow stable rates to be established and measured, and flow rates will be announced when available.
Mosman owns a c.75% working interest in the well and the 350-acre lease. Mosman Operating LLC, a 100% owned subsidiary of Mosman, is the Operator of the lease.
John W Barr, Chairman, said: "The success at Cinnabar-1 confirms Mosman's technical work, indicating considerable potential for additional development wells on the Cinnabar lease.
"This success again reinforces the investment case in South-Eastern Texas where Mosman has participated in several wells, and each one has been placed on production."
