Mart Resources, Inc. and its partners Midwestern Oil and Gas Company PLC (Operator) and Suntrust Oil Company Nigeria Limited announce the following update on production from the Umusadege field, onshore Nigeria.
The initial two-week flow period from the XIIb zone in the Umu-1 well showed strong reservoir performance. The choke size was progressively increased throughout the flow period and a stabilized flow rate of 3,250 barrels of oil per day was achieved on a 26/64 inch choke at a flowing well head pressure of 622 psi. The oil produced was 43 degrees API gravity with less than 0.25% water content, no sand production and a low gas-oil ratio. The stable flowing wellhead pressures seen, and initial analysis of the downhole pressure data, demonstrate that high production rates were achieved with very low pressure drawdown, indicating that the reservoir has excellent permeability and productivity. The detailed production and downhole pressure data is currently being analyzed by independent reservoir engineering consultants. Initial results from this analysis suggest the XIIb reservoir zone has a productivity index (PI) of 150 barrels per day of production rate per 1 PSI of pressure drawdown.
Production from the XIIa zone in the Umu-1 well is now underway and the partners plan to produce from this zone independently for up to two weeks following which they anticipate commingling the XIIa and XIIb zones in order to increase the production rate from the well.
