South Africa: Africa Energy announces 2D and 3D seismic programs offshore South Africa
13 Nov 2019
Africa Energy has announced the award of new 2D and 3D seismic programs on Block 11B/12B offshore South Africa. The operator of Block 11B/12B, Total E&P South Africa, has contracted Shearwater GeoServices for the 2D seismic survey and Petroleum Geo-Services ('PGS') for the second phase of 3D seismic on the block. Both surveys are expected to begin in December 2019 and continue through April 2020. PDF Version.
Jan Maier, Africa Energy's VP Exploration, commented, 'The award of the 2D and 3D seismic contracts demonstrates Total's commitment to move forward quickly with the exploration and appraisal program on Block 11B/12B offshore South Africa. Following the major Brulpadda oil and gas discovery in February this year, the joint venture partners conducted a 570 sq km 3D survey with Polarcus in March and April. We have now analyzed the coring and logging data from Brulpadda and integrated the fast-track 3D data from the Polarcus survey. This data assisted us in choosing the location of the next exploration well, Luiperd-1, which is expected to spud in Q1-2020. The 3D data validated the use of seismic as a direct hydrocarbon indicator, significantly de-risking the remaining prospects on trend. The first phase of 3D data also gave us more insight into the geometry and thicknesses of the reservoir sequences, confirming the large resource potential of the Paddavissie Fairway.'
Total has contracted Shearwater to acquire an initial program of 3,650 linear kms of 2D seismic using the Multi-Purpose Vessel ('MPV') SW Cook with fast-track processing onboard. The 2D seismic program will attempt to define the lead and prospect inventory of the large under-explored area in Block 11B/12B to the east of the Paddavissie prospects.
The operator has contracted PGS to acquire 2,200 sq kms of 3D seismic using the PGS Apollo seismic vessel. In this second phase of 3D seismic work on the block, Total plans to cover the remainder of the Paddavissie Fairway to better delineate the prospects and leads identified on the previous 2D and 3D surveys.
In parallel with the new 2D and 3D seismic programs, Total remains committed to drilling up to three exploration wells on Block 11B/12B in 2020. The Luiperd-1 exploration well is expected to spud with the Odfjell Deepsea Stavanger rig in Q1-2020 and will target large prospective resources approx. 40 kms northeast of the Brulpadda discovery.
Block 11B/12B is located in the Outeniqua Basin 175 kilometers off the southern coast of South Africa. The block covers an area of approx. 19,000 sq kms with water depths ranging from 200 to 1,800 meters. The Paddavissie Fairway in the southwest corner of the block includes the Brulpadda discovery and 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 is operator and has a 45% interest in Block 11B/12B, while Qatar Petroleum and Canadian Natural Resources have 25% and 20% interests, respectively.
