Andrew Benitz, CEO of Jersey Oil & Gas, commented:

"We are very pleased to provide the key findings of the independent Competent Person's Report, which confirm Technically Recoverable Oil Resource Volumes of 94.7 MMstb. Together with JOG's 18% share of the Verbier discovery, this gives a total of nearly 100MMstb net to JOG and provides a contingent resource valuation (NPV10) of nearly US$1 billion net to JOG for Buchan, the J2 discovery, Buchan Andrew and the Company's share of Verbier in the adjacent licence. This independent valuation supports the significant value proposition for developing the base case discovered volumes that JOG owns within its core Greater Buchan Area assets."

Dear Sirs

Competent Person's Report on Licence P2498 (Blocks 20/5a & 21/1a), Greater Buchan Area, UKCS

Jersey Oil & Gas plc (JOG) has engaged Rockflow Resources Ltd (Rockflow) to assess certain oil and gas interests licensed by JOG. These assets include the previously produced Buchan Devonian oil field, the J2 (well 20/05a-10Y) Sgiath and Buchan Andrew oil discoveries and the Capri Prospect. The Effective Date of this assessment is 30(th) September 2019.

JOG is listed on the AIM Market of the London Stock Exchange.

The assessment was undertaken by a team of Rockflow professional petroleum engineers and geoscientists based on data supplied by JOG. Rockflow has relied on the completeness and accuracy of the data supplied by JOG. The data comprised details of licence interests, seismic and well data, technical interpretations, reports and presentations. Rockflow has exercised due diligence and independent analysis where appropriate on all technical information supplied by JOG. Rockflow is not aware of any omission which may materially affect the conclusions of this CPR.

No site visits were undertaken. Rockflow are not in a position to comment on any aspect of health, safety or environment of the assets.

The Resources reported in this document are in accordance with the definitions of the Petroleum Resources Management System (PRMS) approved and updated in June 2018 by the Society of Petroleum Engineers (SPE), the World Petroleum Council (WPC), the American Association of Petroleum Geologists (AAPG), the Society of Petroleum Evaluation Engineers (SPEE), the Society of Exploration Geophysicists (SEG), the Society of Petrophysicists and Well Log Analysts (SPWLA) and the European Association of Geoscientists & Engineers (EAGE).

There are numerous uncertainties inherent in the estimation of reserves and resources. The process of estimating resource volumes is a subjective assessment and cannot be measured directly in an exact way. Estimates carried out by third parties may differ from the estimates presented here. The accuracy of any estimate is subject to the quantity and quality of available data, as well as the geological and engineering interpretation. Results from drilling, testing and production that post-date the preparation of this report may lead to revisions, some, or all, of which may be material. As a result, estimates are often different from the quantities of oil and gas actually recovered, and the timing and cost of those volumes that are recovered may differ from that assumed.

Reserves are those volumes of petroleum that may be recovered by the application of development projects to known accumulations from a given date under defined conditions. Reserves must be discovered, recoverable, commercial and remaining. Reserve estimates of the recoverable oil as of a given date (the Effective Date) may be assigned to certain categories as 1P (Proved), 2P (Proved plus Probable), and 3P (Proved plus Probable plus Possible) Reserves. Reserves may be further divided into various sub-classes, based on the project maturity, development status or production status. All categories of Reserves have been subjected to an Economic Limit Test (pre-tax and before any depreciation allowance) prior to any Net Present Value (NPV) analysis.

Contingent Resources are those volumes of petroleum that may recovered by the application of potential development projects which are subject to one or more contingencies. Contingent Resources may be assigned to a property where there may be, for example, no viable means of production, or to a property where a certain technology is under development, or where a property may be marginally economic under current assumptions, or where an external condition must be satisfied. Contingent Resources can be categorised as Low (1C), Mid (2C) and High (3C) estimates. Contingent Resources may be further divided into various sub-classes, based on the project maturity and/or economic status.

By their very nature, Contingent Resources are less certain to be produced than Reserves, due to technical and/or commercial uncertainties. There is no certainty that any part of the Contingent Resources will be developed.

Prospective Resources are those volumes of petroleum that may recovered from undiscovered accumulations by potential future development projects. Prospective Resources have both an associated Geological Chance of Success (GCoS) that estimates the likelihood of the presence of hydrocarbons, as well as a Chance of Development (CoD). Prospective Resources can be categorised as Low (1U), Mid (2U) and High (3U) estimates, and can be further sub-divided into various sub-classes.

There is no certainty that any part of the Prospective Resources will be developed. If a prospect is drilled, and demonstrates the presence of hydrocarbons, it may then be re-classified as Contingent Resources. The property would then need to be reassessed as to its status and chance of development before any decision can be made as to the likelihood of a potential development project, and whether such a development would be economically and technically viable.

Volumes of oil are quoted in this report at stock tank conditions. Volumes of natural gas quoted herein are volumes of sales gas, after an allowance for fuel gas and process shrinkage. Standard conditions are 60 Fahrenheit and 14.696 psia.

It should be noted that any NPV calculation carried out by Rockflow is not an estimate of the market value of the property. Any such market evaluation would have to consider the risks to the potentially recoverable volumes, any potential for further upside, and geo-political risk, and the state of the market at the time, as well as other factors. Rockflow has not considered any of these risks in assessing the NPV of the properties listed herein.

Notes:

1. The CoD (Chance of Development) indicates the probability that the full field development will be undertaken.

2. Net attributable is based on JOG working interest of 100% (Buchan Devonian field and Buchan Andrew discovery) and 97% (J2 Sgiath)

3. There is a single project currently proposed which will jointly develop the Buchan Devonian field, the Buchan Andrew discovery and the J2 Sgiath discovery.

4. The Buchan Area project is currently in the "Concept Select" phase. The Contingent Resources would be classified as "Development Pending" under SPE-PRMS 2018 definitions.

5. The total is a probabilistic sum of the contributing assets as development is to be through a single project. This is consistent with SPE-PRMS recommendations on aggregation (PRMS section 4.2.5).

6. The Total Contingent Resources (All sub-classes) include all Technically Recoverable Resource Volumes, without any economic cut off applied.

7. The Contingent Resources (Development Pending) have passed an Economic Limit Test, with mid oil-price assumptions.

8. The Contingent Resources (Unclarified) have not passed an economic limit test with the proposed project, but may be recoverable via additional projects.

9. The Contingent Resources (Unclarified) are the difference between the Technically Recoverable Volumes and the Contingent Resources (Development Pending), and results in "low" estimates which are greater than the "high" estimates.

10. The valuation has been based on the Contingent Resources (Development Pending), only.

Notes:

1. The NPV valuation should not be considered as an estimate for the market value of the property.

2. Net attributable is based on JOG working interest of 100% (Buchan Devonian field and Buchan Andrew discovery) and 97% (J2 Sgiath).

   3.   The valuation is a post-tax valuation. 

4. This valuation includes tariff income from the tie-back of the Verbier field, in which JOG has a working interest of 18%.

5. The production profile for the Verbier field has been received from the operator (Equinor) through JOG. The resource volumes (22.9 MMstb of oil and 11.4 bcf of gas) for Verbier have not been independently assessed by Rockflow.

6. There is a single project currently proposed which will jointly develop the Buchan Devonian field, the Buchan Andrew discovery and the J2 Sgiath discovery.

7. The Buchan Area project is currently in the "Concept Select" phase. The Contingent Resources would be classified as "Development Pending" under SPE-PRMS 2018 definitions.

8. The total is a probabilistic sum of the contributing assets as development is to be through a single project. This is consistent with SPE-PRMS recommendations on aggregation (PRMS section 4.2.5).
