Mosman Oil and Gas Limited (AIM: MSMN) the oil exploration, development, and production company, announces a significant reserve update in respect of its producing Cinnabar Project in Tyler County, Texas.
Reserve Report
After the successful development drilling of and production from the Cinnabar-1 well, Mosman commissioned an updated independent Reserve Report for the Cinnabar Project (the "Report").
The Report was prepared on the basis of a potential full-field development of the Cinnabar Project where Mosman has a 75% Working Interest. A wholly-owned subsidiary Mosman Operating LLC operates the Project.
Total Proved Reserves have increased by approximately 78% from 887,000 to 1,581,000 gross boe.

This Report was prepared by D Braxton and Associates in March 2023 and conforms to SPE-PRMS guidelines.
"Gross" are 100% of the reserves and/or resources attributable to the licence whilst "Net attributable" are those attributable to Mosman's Working Interest after royalties.
Theoretical Development Schedule
Reserves are based on a potential full-field development on the producing 352 acre Cinnabar Project involving 5 further development wells with one well drilled in 2023, two in 2024 and two more in 2025. It also assumes well recompletions when appropriate to produce separate production zones. The final development plan remains subject to a number of matters including Board approval and funding availability.
Working Interest (WI)
Mosman acquired 97% WI and farmed out to reduce Mosman's exposure to the Cinnabar-1 well drilling costs. This farmout became effective with the drilling of the well in November 2022 and reduced Mosman's WI to 75%.
John W Barr, Chairman, said: "We are extremely pleased with the new Reserve Report that confirms significant quantities of Reserves at Cinnabar.
"Cinnabar is now the most significant project in Mosman's portfolio both in terms of production and reserves. "
"The Board can now consider the best way to commercialise these Reserves."

Glossary
|
Barrel |
Barrels of crude oil and liquids |
|
BOE |
Barrels of oil equivalent based on calorific value of as opposed to dollar value. The term allows for a single value to represent the sum of all the hydrocarbon products that are forecast as resources. Gas and liquids quantities are converted to an oil equivalent based on a conversion factor that is recommended to be based on a nominal heating content or calorific value equivalent to a barrel of oil. |
|
Gas, Natural Gas or Associated Gas |
A natural gas found in contact with or dissolved in crude oil in the reservoir. It can be further categorized as gas cap gas or solution gas. |

Net Attributable Reserves |
Reserves net to Mosman's Working Interest after royalties |
|
Proved Developed Producing |
Developed Reserves that are expected to be recovered from completion intervals that are open and producing at the effective date. |
|
Proved Developed Behind Pipe |
Reserves that are expected to be recovered from zones in existing wells, which will require additional completion work or future re-completion before the start of production. In all cases, production can be initiated or restored with relatively low expenditure compared to the cost of drilling and completing a new well including hook-up to allow production. |
|
Probable Reserves |
Those additional Reserves that analysis of geoscience and engineering data indicates are less likely to be recovered than Proved Reserves |
|
Proved plus Probable |
The sum of Proved Reserves plus Probable Reserves |
|
Reserves |
Reserves are those quantities of petroleum anticipated to be commercially recoverable by application of development projects to known accumulations from a given date forward under defined conditions. |
|
Royalty |
A type of entitlement interest in a resource that is free and clear of the costs and expenses of development and production to the royalty interest owner. A royalty is commonly retained by a resources' owner (lessor/host) when granting rights to a producer (lessee/contractor) to develop and produce that resource. |
