Pennpetro signs Horse Hill farm-in to Drill New Production Well

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 it has signed a binding term sheet ("Agreement") with UKOG (137/246) Ltd and Horse Hill Developments Ltd ("HHDL"), both subsidiaries of UK Oil & Gas plc (collectively "UKOG") to farm-in and drill the next infill oil production well at the Horse Hill Oil Field ("Horse Hill"), located about 2 km north of Gatwick airport.

The Agreement covers Horse Hill and its surrounding PEDL137 and PEDL246 licences ("Licences") covering an aggregate area of 142.9 km².

The Agreement's binding farm-in terms, which are subject to certain conditions as outlined below, cover the drilling of a new crestal infill well, designated Horse Hill-3 ("HH-3"), to be spudded after the completion of a Pennpetro funded high-definition 3D seismic survey. On completion of HH-3, Pennpetro will receive a 49% share of all production derived from Horse Hill-3 and future wells plus a 49% interest in the Licences. UKOG's subsidiaries will retain their current interests in all oil production from Horse Hill-1 ("HH-1") and HHDL will remain as the named Licence operator.

Tom Evans, Pennpetro's CEO, commented: "We see an excellent opportunity here for Pennpetro to participate in the next phase of developing the Horse Hill Oil Field. We look forward to moving ahead with the planned high-resolution 3D seismic survey as soon as practicable and then moving forwards to the next production well at Horse Hill."

About Horse Hill Oil Field

Following its discovery in 2014, Horse Hill was successfully production tested in the Upper Portland sandstone and underlying Kimmeridge limestone section from 2016 through to the start of long-term continuous Portland production in 2020. UKOG advise that, as of mid-March 2023, continuing oil production from HH-1 totals an aggregate of over 185,000 barrels of 35˚- 41˚ API sweet crude. Full planning and environmental consents are in place for four additional infill production wells.

A 2018 Xodus CPR for UKOG estimated a gross mid case P50 Portland oil in place ("OIP") of 30 million barrels, with a corresponding mid-case 2C recoverable Contingent Resource of 1.5 million barrels. The estimated mid case 5% recovery factor being stated as in accord with other analogous fields in the Weald Basin. It should be noted that the total HH-1 Portland production to date potentially leaves around 1.36 million barrels of the estimated mid-case recoverable Portland resource available to infill drilling and remaining HH-1 production.

In addition to the 132,000 barrels of 35-36˚ API Portland continuous production, approximately 53,000 barrels of 41˚ API sweet crude were produced from multiple zones within the Kimmeridge limestones during production testing, before being shut in to allow for longer term Portland production. In 2015 a Schlumberger report calculated an estimated mean OIP of 8.262 billion barrels lying within the entire Kimmeridge section underlying the Licences. Note: OIP should not be construed as either recoverable Contingent resources or Reserves. The Kimmeridge therefore remains a potentially viable secondary production target at Horse Hill.

About UKOG

UKOG, listed on AIM, is a forward-thinking energy company transitioning from oil and gas into the hydrogen energy space. Its portfolio includes the development of 40 billion cu feet of recoverable gas at Loxley, the UK onshore's largest remaining tested gas resource, stable oil production from Horse Hill and Horndean, plus the 305 km² Resan Licence in SE Turkey where the latest well targeting the shallow Pinarova structure, located beneath a recently discovered active surface oil seep, is expected to spud shortly. In May 2022 it announced its intention to build an integrated hydrogen hub, centred around the UK's largest planned underground salt cavern hydrogen storage facility, all strategically located in Southern England at Portland port in Dorset. It is a member of the Solent Hydrogen Cluster and is actively engaged with government on the future design and operating model of hydrogen storage.
