Multiple drilling targets identified by 3D seismic data

Rose Petroleum plc (AIM: ROSE), the AIM quoted natural resources business, is pleased to announce it has now completed the initial structural interpretation of the 3D seismic data it acquired over its Gunnison Valley Unit ("GVU") which is part of its larger lease holding in the Paradox Basin, Utah, U.S.A. ("Paradox acreage").

The Company is delighted to confirm that key geological structures targeted by 3D seismic have been found to be present across the acquisition area, and following the analysis of the data, multiple drilling targets have been identified.

The structural interpretation, which is an ongoing process, has to date identified 53 well locations in the Cane Creek reservoir zone alone, within the 20 square miles of the GVU lease holding covered by the 3D seismic data. The initial internal resource estimates are consistent with the report prepared by our independent resource analysts, Ryder Scott, in their April 2014 report for the Grand Main leasehold area (85 square miles), which includes the GVU acreage. This report suggests that for the 20 square mile area covered by the 3D, the gross resource potential is as follows:

· Mean unrisked undiscovered Original Hydrocarbon in Place of 450 million barrels of oil equivalent (mmboe), and

· A mean unrisked Prospective Recoverable Resource of 32.5mmboe.

The Chance of Success ("COS") for the Cane Creek reservoir zone was estimated by Ryder Scott at 56%, in their April 2014 report, representing a relatively low risk prospect.

A further 65 square miles of Rose's Grand Main leasehold area and 48 square miles of its Emery Main leasehold area contains additional prospectivity in the Cane Creek reservoir zone and the other Paradox Formation clastic intervals.

Rose's leases are located directly north of the acreage originally held by Fidelity Exploration and Production Co ("Fidelity"), then a subsidiary of MDU Resources Group (NYSE: MDU), and was the lead operator in the development of the Cane Creek Field and adjoining holdings. In 2013, Fidelity produced nearly 1.0 MMBO from the Cane Creek Field from 14 wells. Cumulatively, through January 2017, the field, now owned by Kirkwood Resources, has produced 7.9 MMBO and 5.7 BCFG from 36 wells according to the State of Utah.

Assessment work will now continue to refine the Cane Creek reservoir zone resource potential, high grade first development well locations, and to evaluate additional prospective areas within the Paradox Formation. To elaborate, the Paradox Formation is made up of approximately 24 clastic zones, of which the Cane Creek reservoir zone is the primary producing zone of the basin to date. Additional clastics, above and below the Cane Creek zone, as listed in the Ryder Scott report, are also thought to be prospective. It is these zones, which we will be reviewing in detail within the seismic acquisition area to potentially confirm further resources in addition to those referred to above, which are only within the Cane Creek Reservoir zone.

The Company is now progressing the Application for Permit to Drill (APD) process for the highest priority drill target locations, with a view to drilling the first well on the Paradox acreage in the second half of 2018. The Company is fully funded for these permitting activities.

As previously announced, the Company plans to exhibit the structural interpretation at the upcoming NAPE Summit, in Houston, U.S.A. on 6-9 February at Booth #2367, to focus its efforts to identify partners and investors for its future drilling activities on the Paradox acreage. NAPE is the pre-eminent summit for the oil and gas industry and a prime marketplace for the buying, selling and trading of prospects and producing properties.

Matthew Idiens, CEO, commented: "The initial results from the 3D seismic acquisition are a watershed moment for the Company, with the identification of multiple highly prospective, relatively low risk drill targets with a COS of 56%, on our Paradox Basin acreage. We believe this area represents a highly attractive drilling proposition, supported by excellent quality data that exhibits multiple drilling targets analogous to the structures of previously successful wells, to the south of our acreage.

"The seismic acquisition, which was completed within time and under budget, has delivered on all its key objectives, and the Company is now ready to move forward to the permitting and drilling of the Company's first Paradox wells.

"Negotiations with potential investors and partners to fund the drilling programme are ongoing, and the Board will prioritise options, including joint venture and farm-in arrangements, to ensure that any dilution to existing shareholders is kept to an absolute minimum, while still realising the full value of the project. We will keep the market fully updated on what promises to be a very exciting period ahead for the Company."

Glossary

Undiscovered Original Hydrocarbon in Place: is that quantity of petroleum (oil & gas), which is estimated, on a given date, to potentially be contained in undiscovered accumulations.

Prospective Recoverable Resource: are those quantities of petroleum, which are estimated, on a given date, to be potentially recoverable from undiscovered accumulations by applications of future projects. Prospective Resources have both an associated chance of discovery and chance of Development

Chance of Success: Ryder Scott estimated the Chance of Success (COS) for each zone in each prospect area. In the context of the assessment of an unconventional shale play such as the Paradox Clastics, the COS is intended to represent the total probability that the essential elements of such a play are present in each zone in each prospect area. The COS estimated for each block is based on our assessment of five independent risk factors which are defined as follows:

Presence: The probability that target units of the prospective formation are present in the area being evaluated

Organics: The probability that the target units of the prospective formation will contain sufficient organic material of appropriate kerogen type to provide for the generation of hydrocarbons

Maturity: The probability that the organic material contained in the target units of the prospective formation has sufficient thermal maturity to allow for the conversion of kerogen to oil & gas

Producibility: The probability that there are sufficient intervals within the target units of the prospective formations of sufficiently brittle composition and that the regional stress field is such that the application of completion techniques may provide for movement of hydrocarbons in the reservoir to a wellbore at significant rates.

Continuity: The probability that the other risk factors are favourable over a sufficient lateral area to allow for potential development of the target units of the prospective formations.

The COS does not include the likelihood that a development project in the area evaluated will be economically viable or, if viable, the likelihood that development occurs.

Notes to editors

Rose Petroleum plc (http://rosepetroleum.com) is a North America-focused oil and gas company whose primary asset is approximately 90,000 net acres in the prolific oil and gas producing Paradox Basin in Utah, U.S.A., where it is earning into a 75% working interest. Using high-quality data gathered in a 3D seismic survey completed in October 2017, the Company has identified drilling locations in naturally fractured areas of the Paradox clastics formation with the intention of commencing a drilling programme in H2 2018, once necessary permits and funding have been secured.

The Company's established management is supported by an expert technical team with extensive experience of the basin, where current operations nearby have proven successful, with significant initial production rates and low decline rates, offering strong economics even in the present oil price environment.

The Company's strategy is to grow both organically and through acquisition, identifying additional hydrocarbon assets, conventional or unconventional, that would benefit from the Company's fast-acting, entrepreneurial approach.
