OIL AND GAS The start of something Light oil and gas condensate discoveries could be a game-changer for South African oil and gas BiG If the South African gas market is to take off and thrive, significant drilling has to take place, says the new CEO of Petroleum Agency SA, Dr Phindili Masangane. A major discovery has been made at a site south-east of Mossel Bay called Brulpadda. Dr Masangane says, “The recent discovery by Total and its JV partners in Block 11B/12B (Brulpadda) is the first giant step in that direction.” Total’s first attempt to drill the Brulpadda Prospect in 2014 was suspended before reaching target due to difficulties experienced by the drilling rig in the harsh deepwater environment. After an extensive review of the challenging surface conditions, Total contracted the Odfjell Deepsea Stavanger semi-submersible rig to drill the Brulpadda-1AX re-entry well commencing in December 2018. The Brulpadda well was drilled in approximately 1 400 metres of water by the Odfjell Deepsea Stavanger semi-submersible rig. The well targeted two objectives in a deep marine fan sandstone system within combined stratigraphic/structural closure. Following the success of the main objective, the well was deepened to a final depth of 3 633 metres and was successful in the Brulpadda-deep prospect. The well encountered oil pay and a total of 57 metres of net gas condensate pay over two Middle to Lower Cretaceous high-quality reservoirs. Core samples were taken in the upper reservoir, and a comprehensive logging and sampling programme was performed over both reservoirs. The success at both the Brulpadda primary and secondary targets significantly de-risks other similar prospects on Block 11B/12B. In March and April 2019, the operator acquired 570 square kilometres of 3D seismic with the Polarcus Asima vessel. The first phase of 3D seismic covered the Brulpadda discovery and the Luiperd prospect.

OIL AND GAS at the main objective and illuminates the deep target, confirming the large resource potential of the Paddavissie Fairway. The 3D seismic also increases PASA’s confidence in the sedimentological and structural interpretation and has been integral in selecting the location for the next exploration well on Block 11B/12B, Luiperd-1. The joint venture partnership continues to analyse and integrate the fully processed 3D seismic with the analysis of the core samples and the modular formation dynamics tester (“MDT”) samples. The core indicates a high net to gross in the main objective with good intergranular porosity and permeability. The pressure, volume and temperature (“PVT”) analysis performed on the MDT samples confirmed the high liquid yield in the main gas condensate zone of the main and deep reservoirs. In July 2019, the operator of Block 11B/12B, Total, executed 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 recently mobilised to South Africa from Norway. In May 2020, the Block 11B/12B joint venture received the fasttrack 2D seismic dataset from Shearwater GeoServices Holding AS for the 7 033 linear kilometre 2D seismic programme completed earlier in the year on Block 11B/12B, where the Company holds an effective 4.9% interest. Initial interpretative work has confirmed the Kloofpadda Play Trend, which consists of several large and encouraging leads. The Block 11B/12B joint venture expects the fully processed 2D seismic dataset in late August 2020 and will then begin full prospect analysis for the eastern part of the block. In June 2020, the Block 11B/12B joint venture received the fast-track 3D seismic dataset from Petroleum Geo-Services ASA (“PGS”) for the 2 305 square kilometres 3D seismic programme completed earlier in the year on Block 11B/12B. Initial interpretive work has identified some additional leads, including a potential northern extension to the Luiperd prospect. Africa Energy holds a 4.9% effective interest in the Exploration Right for Block 11B/12B. The Company owns 49% of the shares in Main Street 1549 Proprietary Limited, which has a 10% participating interest in the block. Total as the operator holds a 45% participating interest in Block 11B/12B, while Qatar Petroleum and CNRI hold 25% and 20%, respectively. “Further development of the discovery is highly dependent on the success of this further drilling,” attests Dr Masangane. “Possible development could see condensate being piped to the PetroSA facility in Mossel Bay,” she adds, but these decisions are ultimately up to the operator, Total, and its partners. DR PHINDILE C MASANGANE PHD CHEMISTRY, MBA, BSC. (MATHEMATICS & CHEMISTRY) Dr Masangane was appointed as the CEO of the South African upstream oil and gas regulatory authority, Petroleum Agency South Africa, in May 2020. Before then, Dr Masangane was an executive at the South African state-owned energy company, CEF (SOC) Ltd, which is the holding company of PASA. Dr Masangane was responsible for clean, renewable and alternative energy projects. In partnership with private companies, she led the development of energy projects including the deal structuring, project economic modelling and financing on behalf of the CEF Group of Companies. Her responsibilities also include supporting the national government in developing energy policy and regulations for diversifying the country’s energy mix. In 2019, Dr Masangane was Head of Strategy for the CEF Group of Companies where she led the development of the Group’s long-term strategic plan, Vision 2040+ as well as the Group’s gas strategy. From 2010 to 2013, Dr Masangane was a partner and director at KPMG, responsible for the Energy Advisory Division. In this capacity, she successfully led the capital raising of $2-billion for the Zimbabwe power utility, ZESA/ZPC’s hydro and coal power plants expansion programmes. PASA has successfully attracted major explorers to South Africa and facilitated the acquisition of many new large seismic surveys and some exploratory drilling, through a period affected by legislative issues and a major oil price crash. “PASA’s challenge is to ensure that both international and local energy companies see this value proposition with South Africa and choose our country. In this low oil and gas price environment, companies are inclined to cut back on capital investments and we need to partner with them to sustain the momentum,” says Dr Masangane. ___ __ _ Dr Phindile C.
