Africa Energy provides update on exploration activities
Published by Nicholas Woodroof,
Garrett Soden, Africa Energy's President and CEO, commented: "We are excited to begin an extremely active and potentially transformational period for the company. The Block 11B/12B joint venture operated by Total has embarked on an ambitious exploration programme offshore South Africa to follow-up on the large Brulpadda gas condensate and light oil discovery last year. The 2D and 3D seismic surveys are progressing well and will help us identify additional prospectivity across the block. The upcoming multi-well exploration programme will target several de-risked submarine fan prospects with substantial prospective resources."
Block 11B/12B, offshore South Africa
On 9 December 2019, Shearwater GeoServices Holding AS (Shearwater) commenced an initial 2D seismic program of 3370 linear km using the Multi-Purpose Vessel SW Cook. The goal of the 2D seismic programme is to define the lead and prospect inventory of the large under-explored area in Block 11B/12B to the east of the Paddavissie Fairway. Shearwater has completed approximately 3300 linear km to date, and the joint venture has increased the scope of the initial programme. The additional 2D seismic will focus on the highly prospective areas of interest identified with onboard fast-track processing and recently reprocessed legacy 2D seismic data.
On 29 December 2019, Petroleum Geo-Services ASA (PGS) commenced the second phase 3D seismic programme of 2200 km2 using the PGS Apollo seismic vessel. In this second phase of 3D seismic work, the joint venture plans to cover the remainder of the Paddavissie Fairway, including a vast extension to the north, to better delineate the prospects and leads identified on the previous 2D and 3D data. PGS has completed approximately 540 km2 to date.
In March and April 2019, Polarcus Limited (Polarcus) acquired 570 km2 of 3D seismic using the Polarcus Asima vessel. This first phase of 3D seismic covered the Brulpadda discovery and the Luiperd prospect. The joint venture received the preliminary, fast-track 3D results in August 2019, and the company expect to receive the fully processed Polarcus 3D seismic dataset by February 2020. Prospectivity at the main target, the Cretaceous deep marine fan sands, has been delineated well on the fast-track 3D data. The company expect to identify further prospectivity with associated Amplitude Variations with Offset (AVO) responses at the deeper targets on the fully processed 3D dataset.
In July 2019, the joint venture entered into a multi-well drilling contract with Odfjell Drilling for the Deepsea Stavanger semi-submersible rig, the same rig that drilled the Brulpadda discovery in February 2019. The rig is currently under contract drilling production wells for Aker BP in the North Sea. After the rig is released by Aker BP, it is expected to spend approximately two weeks at the Semco Maritime shipyard in Bergen, Norway for maintenance and modifications before mobilising to South Africa. According to the updated rig release schedule, the Luiperd-1 well is expected to spud in 2Q20. The joint venture plans to keep the rig on Block 11B/12B for almost a full year in order to drill up to three consecutive exploration wells.
Block 11B/12B is located in the Outeniqua Basin 175 km off the southern coast of South Africa. The block covers an area of approximately 19 000 km2 with water depths ranging from 200 to 1800 m. The Paddavissie Fairway in the southwest corner of the block includes the Brulpadda oil and gas discovery, as well as several large submarine fan prospects that have been significantly de-risked by the discovery and subsequent 3D seismic work.
Africa Energy holds 49% of the shares in Main Street 1549 Proprietary Limited, which has a 10% participating interest in Block 11B/12B. Total E&P South Africa B.V. is operator and has a 45% interest in Block 11B/12B, while Qatar Petroleum International Upstream LLC and CNR International (South Africa) Limited have 25% and 20% interests, respectively.
Block 2B, offshore South Africa
Management continues its efforts to farmout a portion of the company's interest in Block 2B in order to drill an additional exploration well in 2020. The planned well would test the up-dip extent of a rift basin oil play proven by the A-J1 oil discovery in 1988.
Block 2B is located in the Orange Basin and covers 3604 km2 off the west coast of South Africa approximately 300 km north of Cape Town with water depths ranging from 50 to 200 m.
Africa Energy holds a 90% participating interest and is the operator of Block 2B. Crown Energy AB indirectly holds the remaining 10% participating interest.
PEL 37, offshore Namibia
The PEL 37 joint venture recently received a one-year extension to the Second Renewal Exploration Period until 21 March 2021. Several operators in Namibia are planning nearby exploration wells this year that could de-risk the remaining PEL 37 prospects.
PEL 37 covers 17 295 km2 in the Walvis Basin offshore Namibia approximately 420 km south of the Angolan-Namibian border. Water depths over PEL 37 range from 400 to 1500 m.
Africa Energy holds an effective 10% interest in PEL 37. The company owns one-third of Pancontinental Namibia (Pty) Limited, which holds a 30% participating interest in PEL 37. The other joint venture partners in PEL 37 are Tullow Namibia Limited, the operator with 35% participating interest, ONGC Videsh Limited with 30% participating interest and Paragon Oil and Gas (Pty) Limited with 5% participating interest.
