OFFSHORE OIL EXPLORATION LAMU TO KWALE

     



“We are exploring offshore Kenya, and apparently it has the same kind of prospects as offshore Tanzania and Mozambique,” Christophe de Margerie told Dow Jones Newswires in an interview. “There might be oil too, we are not just looking for gas. We have acquired the seismic results, but until you drill, you don’t know.”BEIJING (Dow Jones)–French oil and gas major Total AS (TOT) plans to drill its first offshore East Africa exploration well early next year, hoping to emulate huge gas discoveries made by other oil majors offshore Tanzania and Mozambique, the company’s chief executive said Sunday
Onshore in Africa “we have been acquiring a lot of blocks in Kenya, have acquired part of the shares of Tullow Oil PLC (TLW.LN) in Uganda and have acquired blocks in Congo on the other side of Lake Albert, and we will be able to start exploring sooner or later in South Sudan.”
Offshore West Africa, Total will drill by end-2012 for the first time in an Ivory Coast block acquired two years ago, he noted.
Total has said it plans to grow its oil and gas output by 3% this year and 2.5% annually through 2014, assuming crude price stay around $100 a barrel.
Pancontinental Oil & Gas and its wholly owned subsidiary Afrex Limited together with partner FAR has received approval from the Kenyan Ministry of Energy and Petroleum for the farm-out of the onshore portion of Kenyan exploration area Block L6 in the Lamu Basin. Block L6 is partly onshore and partly offshore.



Block L6/L8
Under the terms of the farm-in with Milio E&P Limited and Milio International (“Milio”), Pancontinental will be fully funded through the drilling and testing of a high impact onshore exploration well in Block L6 expected to spud in H1 2015.
Pancontinental will also be fully funded through the acquisition, processing and interpretation of a regional onshore 1,000 kilometre 2D seismic survey. This is expected to confirm a number of prospects in onshore L6 as drill targets. This seismic program is expected to commence in April 2014.
Pancontinental retains a 16% interest in the onshore part of Block L6 and also preserves its 40% interest in the highly prospective offshore part of Block L6 which operator FAR has estimated to contain substantial prospective resources. FAR is also currently in discussions with parties to farm-in to drill an offshore well in Block L6.
Block L6 is well situated in relation to Kenyan coastal communities and infrastructure.
An onshore oil or gas development has the potential to contribute significantly to Kenya’s growing near-term energy needs.
Two of the main Prospects covered by 3D seismic offshore L6 are the Kifaru and Kifaru West Miocene Reef prospects, which share similar characteristics to the Sunbird Prospect currently being drilled by Pancontinental and its joint venture partners in offshore Kenya area L10A.
Barry Rushworth, CEO and Director of Pancontinental commented:
“We are very pleased that the Kenyan Ministry of Energy and Petroleum has approved the farm-out agreement announced on 4 February 2014. Pancontinental retains a healthy 16% free-carried interest onshore and additionally has the benefit of retaining its 40% interest offshore where we are also seeking a farminee for drilling. This farm-in deal secures funding for evaluating the significant potential of the onshore part of Block L6 and to help unlock the potential of the wider Lamu basin in which Pancontinental has a very large acreage position of some 20,000 square kilometres gross.
“The offshore area already has several Prospects covered by 3D seismic and ready for drilling including the large Kifaru and Kifaru West Miocene Reef Prospects. A number of other reefs have also been tentatively identified on 2D seismic.”

Overview
Blocks L17 and L18 are in the Lamu Coastal Basin, offshore south-east Kenya, covering an area of approximately 4,881 km2. They are situated in water depths varying from a few feet along the shoreline to up to around 2,625 ft in the Pemba Channel. There are several potential source rocks for the Tertiary and Cretaceous plays in the southern areas of the basin including the Permo-Triassic Karoo interval, the Middle Jurassic and high Total Organic Carbon (TOCs) are recorded within the Eocene section in the Pemba-5 well. There are oil seeps in the Lamu Basin and Pemba Island linked to a Jurassic source which implies that the structures in Blocks L17 and L18 are most likely oil bearing. The hydrocarbons are expected to have been generated in the deep Pemba trough south of Block L18 and in the Tembo Trough to the east. In January 2012, Afren completed the acquisition of 1,207 km of additional 2D seismic data targeting the deeper water portion of the blocks. Interpretation of the data has identified four new highly encouraging prospects, in addition to the previously mapped prospects in the shallow water. These prospects represent a major new play and together have increased mean prospective resources on the blocks, from 94 mmboe to 2,021 mmboe, sincethe Black Marlin acquisition. As a result Afren, in close consultation with the Ministry of Energy, completed the acquisition of 1,006 km2 3D seismic during December 2012, in lieu of the well commitment, to better understand the deep water prospectivity prior to exploration drilling. In addition, we commissioned an onshore 2D seismic survey of 120 km in September 2012 to simultaneously continue maturation of the shallow water/onshore play. This survey was completed in December 2012. Interpretation and rock property studies on the 120 km onshore 2D seismic and the1,006 km2 offshore 3D seismic are underway. The seismic data has highlighted an expansive shallow-water/onshore trend called the Mombasa High.


Outlook
Preparations are underway for the 2015 two well drilling campaign on the Mombasa High anticline which extends over 80 km from Mombasa to the Shimoni Peninsular. This giant structure sits on the western margin of the Tembo Trough which has recently been tested by BG Group on the Sunbird-1 oil discovery, Block L10A. The Sunbird-1 well encountered a 46 ft oil column in a Miocene reef and is the first oil discovery offshore Kenya. The confirmation of an oil prone petroleum system within the Tembo Trough has significantly derisked Afren’s prospects on the flanks of this basin.An airborne gravity and magnetic survey was acquired over the Mombasa High structure in Q2 2014 to allow the optimal positioning of a 250 line km 2D seismic survey which will be acquired later in the year. The seismic survey will be used to define the location of the exploration wells.
