Tax-efficient exploration on the NCS
In 2005, Norway introduced a groundbreaking new tax initiative, where it started to directly compensate oil and gas companies for exploration activity. Since this time, the Norwegian government has provided a rebate in the following year equal to 78% of the capex spent in the previous year on exploration drilling. Exploration wells effectively became 78% cheaper to drill overnight and resulted in an immediate increase in exploration activity that has continued to today. In recent years, lower activity in the mature Norwegian North Sea has been partly offset by increased activity in the more frontier Norwegian Sea and Barents. The prize on offer is the potential for more material discoveries with exploration running but at the cost of limited infrastructure access and higher well costs.

Post-discovery, the Norwegian fiscal regime allows for capital allowances resulting from almost all E&P investment activities, in addition to uplift (an additional tax shelter), to be deductible against tax. Norwegian E&P companies are taxed at 78% on profits; hence, this is a substantial boost for companies that can offset investments in developments and operations against profits from production.
In addition to relatively low post-tax exploration costs, the maturity of the NCS and data coverage provide for relatively high exploration success rates, but against a fall in mean discovery size as basin creaming curves evolve. The average technical success rate over the past 10 years was c 52%, but with mean discovery sizes falling below 35mmboe (excluding John Sverdrup) commercial success rates average c 31%. Increasing infrastructure density and the recent rise in commodity prices ensure that the minimum threshold for commerciality continues to fall.

Taking into consideration data post-Johan Sverdrup, (2011–2017), and applying historical average actual data for chance of technical success (48%), mean discovery size (31mmboe) and average post-tax exploration well cost of $12.3m (gross cost $55.9m), this would imply that a technical finding cost of c 0.83$/boe should be achievable. Assuming the same mean volume for a commercial success, at a historical success rate of 31%, this would imply a finding cost of $1.3/boe. This is broadly in line with Faroe’s historical finding cost for commercial discoveries of c $1/boe.

We look at historical technical finding costs (post-tax) across the three major NCS offshore areas in Exhibit 20. Technical finding costs in the Barents are low, due to a combination of relatively high historical technical success rates and the discovery of Johan Castberg (c 500mmboe), which positively skews mean discovery size. However, while we do not have historical data on commercial success rates by offshore area, we would expect commercial success rates to be relatively low compared to the North Sea in the Barents, due to the lack of available infrastructure and the need for discoveries to justify standalone development.

Seven further E&A wells in H218 and 2019
Faroe commenced an E&A drilling programme in late 2017 and to date has achieved significant successes with the Iris/Hades discoveries and the appraisal of nearby Fogelberg. Iris/Hades discovered gas condensate across two separate reservoirs estimated to hold combined gross 2C resources of 210mmboe. Meanwhile, the appraisal of Fogelberg has resulted in a preliminary gross resource range estimate of 40–90mmboe and the company is now preparing to carry out development planning studies for a subsea tie-back to Åsgard B in H2 2018. Six further exploration wells, together with an appraisal well in Iris/Hades, are committed for H2 2018 and H1 2019, with further targets being matured for potential addition to the current programme.

Iris and Hades: 2018 discoveries
Iris and Hades, originally known as Aerosmith and Zappa, sit across the PL644 and PL644B licences in the Halten Terrace area of the Norwegian Sea and to the north of Njord. Faroe holds a 20% WI in the licences, which are operated by OMV (30%) and partnered by Equinor (40%) and Spirit (10%). The prospects were identified in PL644 by Faroe and the JV subsequently applied for and was awarded PL644B as an extension in APA 2015. The Iris/Hades exploration well, 6506/11-10, targeted the Cretaceous Lange in Hades and the underlying Jurassic Garn in Iris and completed drilling in April 2018. The reservoirs are high pressure/high temperature (HPHT) and gas condensate was encountered in both prospects with pressure data indicating separate accumulations. The Garn reservoir in Iris is 218m thick and of moderate-to-excellent quality, while the Lange sandstones in Hades are of moderate-to-good quality. OMV assigns a combined gross resource of 48-245mmboe to Iris/Hades, of which c 25% is condensate. At this point in time, we assume a mid-case volume based on figures released by the NPD/OMV at 147mmboe for Iris-Hades in our valuation. However we note that Faroe Petroleum is internally holding a higher resource range of 63mmboe (1C), 210mmboe 2C and 322mmboe. An appraisal well is planned for H1 2019 to confirm the 2C estimates and will target the crest of the structure to the south of the discovery well. Key to the success of the well will be the extent to which the good quality Garn reservoir is distributed across the structure.
We believe there are three possible development scenarios for Iris/Hades. These include:
■
Tieback to Asgard: a low production plateau solution with low up-front capex that utilises multiple subsea tiebacks to Asgard, taking advantage of available gas processing capacity.
■
Standalone development: likely a large fixed or floating platform that is directly connected to the Polerled wet gas pipeline. This will be a high upfront capex cost solution but with high plateau production rate.
■
Asgard interconnector to Polarled: a development solution that will utilise/expand gas processing capacity at Asgard. Iris/Hades subsea wells would be tied back to Asgard and the platform modified in order to receive/process higher volumes of wet gas. Partly processed gas would then be exported via an interconnector to the Polarled wet gas pipeline. We see this as a solution that may allow a high plateau production but at lower cost than a standalone development.
Given the uncertainty with regard to development solution for Iris/Hades ahead of further appraisal, we conservatively assume a tie-back to Asgard similar to Fogelberg in our base case valuation. We limit plateau production to 25kboed gross from 2024, which is substantially lower than the 100kboed gross Faroe management thinks may be achievable under a standalone/interconnector development case. We will reassess valuation of Iris/Hades post-appraisal.
Fogelberg
Fogelberg is also an HPHT discovery that sits in the Halten Terrace area and to the east of Iris/Hades. Faroe holds 15%WI in the PL433 licence, operated by Spirit Energy. The discovery well, 6506/9-2 S, was drilled in 2010 and encountered gas condensate in the Jurassic Garn and Ile reservoirs. The well was drilled high on the structure and did not observe a fluid contact, so the original volumetric range was quite wide at 19–116mmboe. An appraisal well with a sidetrack was drilled, and a DST carried out in 2018, with a view to narrowing this range in reserve estimates and to provide additional information for development planning. The appraisal well, 6506/9-4S, was drilled downdip of the original well and established better reservoir quality reservoir and a deeper gas water contact than previously modelled. The well was subsequently sidetracked as 6506/9-4A and successfully tested at a maximum constrained and stable rate of 21mmscfd and 547bpd condensate (ie 4,047boepd), with no depletion seen over the 24-hour flow period. Faroe has estimated a preliminary resource range of 40–90mmboe on the basis of the new well data; however, this will be updated once the data has been incorporated into the reservoir model. The company is preparing to start development planning studies in H218 on tying Fogelberg back to Åsgard B, 18km to the south. Capacity has been booked in the Asgard transport system (ATS) for 2021–2023.

Rungne and Brasse East: Targeting additional resources for Brasse
Rungne (40%WI) and Brasse East (50%WI) are both operated by Faroe and will be drilled back to back from September 2018, with the potential to add further resources to the existing net 2P reserves of 30.7mmboe (NPD 34.6mmboe) in the planned Brasse development, also operated by the company and one of the largest finds on the NCS in 2016 and 2017. The region is a prolific hydrocarbon-producing area: the majority of the fields and discoveries in the area produce from the Brent Group reservoirs and the exploration success rate has been 67% over the past decade. Rungne is located 35km to the NW of Brasse, close to the Oseberg, Veslefrikk and Huldra fields, which have produced over 3bnboe between them. The prospect is analogous to the Oseberg field, where the reservoir is thick with high net to gross sands and good permeability and is estimated to hold c 70–100mmboe gross recoverable resources. Faroe has identified an AVO anomaly that conforms to the mapped structure and is considered to have a high chance of success. Brasse East is targeting gross 13mmboe, but if successful will also de-risk the Brasse Extension, which would likely then be brought forward for drilling in 2019.
Agar/Plantain: Return to UKCS
Agar Plantain is an exploration and appraisal well located in the UK sector of the North Sea and is Faroe’s first well in UK waters since 2013. The company farmed into a 25% interest on the sole risk drilling activity and a 12.5% interest in the P1763 licence in August 2018, 10 days before the well was spudded by operator Azinor Catalyst. The Plantain exploration well will target Eocene Frigg sands, which were proven by the Agar discovery well, 9/14a-15A, in 2014 and by the 24/9-12S Frosk oil discovery made by AkerBP in Norway in January 2018. Faroe identified that the seismic anomaly present in Frosk continued on to Plantain and Agar. The prospect is also considered to be an analogue of the Catcher field and Cairn Energy, which holds a 20%WI in Catcher, has also farmed into Agar/Plantain. Plantain will be followed by a contingent sidetrack to appraise Agar. Agar and Plantain are estimated to hold combined mid-case prospective resources of 60mmboe, with an upside of 98mmboe.The gross well cost is estimated by Faroe to be US$15m. Agar/Plantain will require further appraisal if the well is successful and benefits from multiple potential development options, including via the Beryl Bravo platform (12km), and the Alvheim FPSO (14km).
The Pabow prospect sits in the Stord basin, and close to the producing Skirne, Jotun and Ringhorne fields. The PL 870 licence was awarded in February 2017 and Pabow is planned to be drilled in late 2018. The Equinor operated well (Faroe 20%WI), will target gross gas resources of 70 – 200 mmboe in the Lower Jurassic Statfjord and will test both a proven source and migration model and an unproven deeper gas source rock that would rely on fluid migration through fractures to accumulate in the sandstone reservoirs.
Cassidy and Bergknapp confirmed for 2019
Faroe has confirmed that it will drill exploration wells on the Cassidy and Bergknapp (formerly Yoshi) prospects in 2019; however, additional new prospectivity is under consideration to be drilled during the year, including an exploration/appraisal well in the Gomez prospect and SE Tor chalk oil discovery, and an exploration well in the Canela Prospect.
Cassidy
Cassidy is 8km north of, and on trend with, Oda and is expected to be drilled back-to-back with the Oda production wells in Q119. Faroe holds a 15% WI in the Spirit-operated prospect. The well will target the Upper Jurassic Ula reservoir in the southern compartment of a salt dome structure and there is flexibility built into the drilling programme to allow appraisal sidetracks, if required. The company estimates gross prospective resources of c 50–110 mmboe, and in the case of success Cassidy could be developed via a subsea tie-back to Ula via Oda (6km away).
Bergknapp
Faroe holds a 30%WI in the Bergknapp prospect, which will be drilled in 2019. Bergknapp sits immediately to the south of the Smørbukk South Field and is also close to the Maria development, so can be tied back to nearby infrastructure in the event of success. The Wintershall operated well will target gross resources of 30–60 mmboe in several Early to Middle Jurassic reservoirs, similar to those producing in Smørbukk South.
