London, 28 March 2023 - Pennpetro Energy PLC (LSE:PPP), an independent oil and gas company focusing on production and development in Gonzales County, Texas, USA, today announces that its wholly owned subsidiary, Nobel Petroleum USA Inc. ("Nobel"), has spudded its first well under its recently signed Joint Operating Agreement with 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: "The Whistling Straits #1H well, to be drilled within the Gonzales County AMI with Millennium, is the first of hopefully many wells to be drilled in Texas under our new Joint Venture that we announced two weeks ago. We look forward to updating shareholders about all developments during this exciting time for the Company."

Andy Clifford, Nobel's President, commented: "The Whistling Straits #1H well is a sidetrack from Millennium's Chalk Talk #3H well which had targeted a deeper section of the Austin Chalk - the Austin Chalk "B" interval. The well will be completed as an open-hole completion connecting naturally occurring fractures with supplemental contribution from matrix porosity without the requirement of fracking." 

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.
