Tanager Energy Inc. is pleased to provide a status update regarding placing the first well within the Joffre D3 B Pool on production.
Joffre Project:
The Joffre Project, in which Tanager has a 50% working interest, consists of 4 suspended oil wells and 1 suspended water injection well. As previously announced, Viking Investments Group, Inc.("Viking") and Tanager Energy Inc., joint venture operator of the Joffre Project, intend to mobilize and reactivate each well sequentially.
Pressure Test:
The mobilization and reactivation process with respect to the first well commenced in November, 2014. In December, 2014 Tanager completed the re-entry and downhole pressure survey to determine the current reservoir pressure, a critical element in determining the scope and anticipated production of this suspended oil pool. The survey confirmed the reservoir pressure returned to 94% of the original pressure (i.e. the pressure that existed when the pool was discovered in 1986) due to the active water drive in the pool.
Production Test:
Following the pressure test described above, Tanager arranged to perform a production test to confirm the productivity of the pool. The production test occurred between January 13th and January 15th, and the test results indicated the following:
- a stabilized production rate of 290 BOE/d (235 barrels per day of oil and 325 mcf/d of gas).
- the flowing wellhead pressure was stable at 475 psi, estimated to be a 7.7% drawdown of the reservoir. On a metric equivalent basis this is 52.5 cubic meters oil equivalent per day at 3265 kpa flowing wellhead pressure.
- The fluid produced was 100 percent high gravity oil.
For the first 4 hours the well flowed at 875 BOE/d at 262 psi wellhead pressure. The production rate was reduced for the final 12 hour test period to keep the reservoir drawdown to less than 10%.
Connecting Well to Pipeline:
Following the production test described above Tanager commenced efforts to place the first well on production through the existing pipeline located at the edge of the subject property. Such efforts included the design engineering for the equipment and piping for the tie-in to the separator, the flowline tie-in to the wellhead, and the re-activation of the discontinued flowline and its change in use from a gas line to an oil effluent line and its subsequent hydrostatic pressure test. While it was expected this would be completed by the end of February 2015, difficulty in finding the necessary information from the previous owners has delayed both the application to the Alberta Energy Regulator for approval to change the existing well flowline from a gas pipeline to an oil effluent pipeline, and the subsequent hydrostatic pressure test of the line. It is currently taking approximately 2 weeks to get approval from the Regulator once the application is accepted. The engineering design and fabrication of piping to connect the separator is underway and it is now expected that this work will be completed and the well placed on production by the end of March, 2015.
