Permex Petroleum Corporation Announces Scheduled Waterflood Enhanced Oil Recovery
VANCOUVER, BRITISH COLUMBIA – June 18, 2018 -- Permex Petroleum Corporation (“Permex” or the “Company)” (CSE: OIL) The Company announces that it is on schedule to mobilize a workover rig and crew to the Pittcock North Tannehill Unit (situated in Stonewall, Texas) next week to commence the Enhanced Oil Recovery (“EOR”) program within the Upper and Lower Tannehill formation. Once the workovers are finalized the initial project will be a water flood utilizing two injection wells and five active receiver wells. When the reservoir is successfully pressured up and increased oil sweep can be recognized in the five receiver wells, management will expand the waterflood to cover all twenty-one oil wells located on the North and South lease.
The primary rationale for waterflooding an oil reservoir is to encourage oil production, helping increase pressure and oil movement to ultimately enhance recovery. For the planned EOR program, water will be injected into the formation to stimulate and support reservoir pressure to sweep and move additional oil within the reservoir toward adjacent receiver wells (secondary recovery). The produced water will then be recycled and reinjected through existing surface facilities and injection pumps. Management has completed extensive engineering studies on the field to create an alternative injection pattern that focuses on maximizing oil sweep through the reservoir back to the receiver wells, where it can be ultimately recovered.
Depending on reservoir characteristics, primary recovery generally recovers approximately 10 to 20% of the original oil in place, while secondary recovery (water flooding) can increase recovery to 30% or more of the total of original oil in place. The planned EOR program will additionally utilize cutting-edge polymer gels and/or surfactants, which can potentially increase oil recovery by an additional 10 to 30% by improving sweep efficiency in the reservoir, thereby greatly enhancing the productivity and economics of the development.
Management has previously waterflooded the field successfully, however due to mechanical downhole issues, the maximum water injection rate only ever reached 450 barrels of water per day (“bwpd”), which resulted in approximately 45 barrels of oil in daily production (10% of total fluid produced). For perspective, the maximum available water to inject from the current water supply well on the property is 2,000 bwpd which, at the same assumed 10% conversion rate, would imply closer to 200 barrels of oil in daily production from this field.
“We have successfully waterflooded this field in the past, so we know that we can achieve similar if not better results with this revised recovery program. In the past, due to the highly corrosive barium within the field, we had downhole issues such as hole in tubing on the water supply well which halted our waterflooding in the middle of our work program. As such, we plan on restarting the waterflood from scratch, utilizing one of the industry-leading Schlumberger ESP (Electric Submersible Pump) units this time to allow us to bypass rod or tubing issues so we can gradually increase water injection to 2,000 bwpd and recover much higher daily oil volumes”, said Mehran Ehsan, President and CEO of Permex.
The EOR process is expected to have long term benefits to the field’s production profile. The Pittcock Field produces oil which is currently benefitting from higher WTI prices. The company anticipates announcing an update as soon as results of the secondary recovery are established.
Some of the offset operators to this property which use secondary or tertiary recovery methods include Kinder Morgan’s Katz field which produces over 4,000 barrels of oil per day through tertiary recovery.
