Pentanova Energy Provides an Update on the Testing of Istanbul-1

VANCOUVER, April 3, 2018 /CNW/ - In light of the recent negative trading in its shares since its March 28 news release on the Istanbul-1 well, PentaNova Energy Corp. (the "Company") (TSXV: PNO), would like to clarify both the drilling results and the factors surrounding the testing the Istanbul-1 well ("the well").

The well, located in the Maria Conchita block in northern Colombia, commenced drilling on February 27, 2018 and reached a total depth of 8,740 feet measured depth ("MD") on March 21^st. When drilling through potential reservoirs of the Jimol formation, the same formation that tested a combined rate of 18 million cubic feet per day of gas in the Aruchara-1 discovery well, gas shows were observed on the mud log.

Open hole logs run between March 21^st and March 24^th revealed 88.5 feet of low resistivity, potential gas bearing sands with an average porosity of 20.3%.  During logging, 32 sidewall core plugs were cut and recovered, the analysis of which supports the interpretation of favourable reservoir properties for the potential gas bearing reservoir intervals identified on logs.

After logging, a 7-inch liner was run to a depth of 8,732 ft MD and cemented. Subsequent cased hole logs acquired on March 30^th showed a good quality cement bond across the intervals of interest.

Based on the interpretation of the open hole logs and mud log, 12 separate intervals covering a total thickness of 62.4 feet were selected and perforated for testing.

Currently, a permanent production completion is being run in hole, after which the drilling rig blow-out-preventers will be removed and a production Christmas Tree installed and pressure tested.

Following completion of the well, flow testing of the potential gas bearing perforated intervals will start and will last for three to four days. The testing will consist of a series of flow periods at different rates, punctuated by shut-in periods to measure the pressure response of the well. Towards the end testing, a production log will be run in order to determine the relative contribution of the different perforated intervals to the overall total flow.

Once the testing of the well has been completed, PentaNova will provide a full and comprehensive update on the results of the test.
