Texas Oil Well - Drilling Ahead in Primary Target Horizontal (Side-Track) Level

Highlights:

·     Drill bit has reached the Austin Chalk interval below the 7 inch casing shoe at its target depth of -7,303 feet true vertical depth subsea ("TVDSS")

·     Drill bit now cutting fresh ground along the planned 4,800 feet lateral (or "Horizontal Side-Track") within the Austin Chalk's primary oil target interval.

London,  5 April 2023 - Pennpetro Energy PLC (LSE:PPP), an independent oil and gas company focusing on production and development in Gonzales County, Texas, USA, notifies that drilling operations have progressed smoothly on the Whistling Straits well with the drill bit now being at a vertical target depth of -7,303 feet TVDSS and has now commenced drilling the planned 4,800 feet lateral within the Austin Chalk target interval.

The Whistling Straights well has been renamed the "Whistling Straits #5H" well (previously referred to as the "Whistling Straits #1H well) and is the first well under its recently signed Participation, Development and Option Agreement between Pennpetro's 100% owned subsidiary, Nobel Petroleum USA Inc, and Millennium PetroCapital Corporation ("Millennium") within the 250,000 acre (1,011 square kilometres) Area of Mutual Interest ("AMI") petroleum joint venture in Gonzales County, Texas.

Tom Evans, Pennpetro's CEO, commented: "I am very pleased with the progress made this week with drilling our first development well in the Peach Creek Oil Field in partnership with Millennium. We are now drilling fresh ground in the Austin Chalk horizontal side-track heading towards the primary oil target. We have high expectations for the well and I look forward to updating shareholders in the coming days as we progress towards reaching total depth and completion."

Andy Clifford, Nobel's President, said: "We are targeting the heart of an interpreted microfracture swarm within the Austin Chalk, identified by cutting-edge 3-D reprocessing and interpretation coupled with analysis of regional well results in preparation for drilling the well, best positioning the well to deliver the highest potential production from naturally-occurring fractures." 

The Gonzales County 250,000 acre (1,011 square kilometres) AMI is located about 290 miles (466 kilometres) due west of Houston and will provide PPP's Nobel with a large inventory of low risk development options in a world class oilfield.

Nobel is paying 33.33% of the cost to drill and complete this joint development well connected to the storage tanks for a net 25% working interest (18.75% net revenue interest) as well as a prospect fee which covers sunk costs relating to leasing, land, legal, 3D seismic licensing, geological and geophysical analysis.
