UK North Sea gets shot in the arm with Glengorm

CNOOC, Total and Edison have made one of the biggest finds in the UK North Sea in recent years. The Glengorm discovery is estimated to contain recoverable resources of 250mmboe which is even bigger than Total’s recent success in the West of Shetlands at Glendronach which had 1tcf of gas (c.160mmboe). Glengorm sits on licence P2215 and in the vicinity of both the Culzean and Elgin & Franklin gas fields which could act as future hosts for Glengorm.

Glengorm is operated by CNOOC (50%) with Total (25%) and Edison (25%) as partners. The exploration well (22/21c-13) was spud on 26^th August 2018 with the Prospctor 5 jack-up rig targeting the Upper Jurrasic Fulmar and Heather formations. The HPHT prospect was challenging to drill but persistence has paid off. CNOOC tried to drill the prospect twice in 2017 but failed to do so following technical problems.

Maersk, Premier Oil and Centrica had relinquished the licence in which the field is contained back in 2014 when it was deemed too small and complex to commercialise. Glengorm has clearly exceeded all expectations with unrisked recoverable resources estimated at c.65mmboe back in 2014 (41mmbbl oil and 128bcf gas). The 2014 relinquishment report also highlights a number of prospects in the vicinity and CNOOC, Total and Edison have expectations of further prospectivity in the area for future growth.

Venture Global doubles LNG supply contract with Shell on Calcasieu Pass

On 6^th March, Venture Global announced that it had agreed to double its gas sales with Shell North America LNG from 1mtpa to 2mtpa under an amendment to the earlier gas sales agreement for LNG from Calcasieu Pass.

This brings the total committed capacity to 3mtpa with Edison having agreed 1mtpa in September 2017. The sale contracts are for 20 years and under FOB terms. The counterparties to date provide validation of the attractiveness of the project being one of the lower cost, mid-scale liquefaction projects and shows confidence in it going ahead and being able to deliver LNG in a reasonable timescale.

The Calcasieu Pass project is for 10mtpa with easy access to the sea and more than a mile of deep water frontage. It is waiting for non-FTA export approval later in 2018 following which it will look to take FID dependent on securing of further gas sales contracts. Venture Global sees first commercial operations at the end of 2021.

Nova development could face delays with Gjøa tie-back challenges

Nova (formerly Skarfjell) is planning to submit the field development plan to the Norwegian authorities in H1 2018. The selected development concept is four production wells and three injection wells from two subsea templates tied back to the Gjøa platform. Neptune which operates Gjøa has raised concerns about the potential tie-back which it has now raised with the Ministry of Petroleum.

Nova is an oil and gas field operated by Wintershall and this would make it the company’s second development in Norway after Maria. The field is estimated to contain c.100mmboe of resources with c.70% oil. In December, the Ministry ruled that field that tie-back to existing infrastructure only need to cover the direct incremental costs of the host platform and not any of the existing operational costs. This was intended to boost activity in Norway. However, Neptune claims that the tie-back could increase overall costs for Neptune as well as impact its ability to tie-back its own discoveries including Cara and 35/9-3 in the vicinity.

A response from the Ministry is now pending and the ruling could determine how the Nova development plan filing will proceed.

The Nova partners are Wintershall/DEA (35% operator/10%), Cairn (20%), Spirit Energy (20%) and Edison (15%).
