characteristics. Gas and indications of liquids were encountered during drilling but significant hydrocarbon shows were not encountered in the target formations. Drilling operations have concluded there. Tower Resources has announced the completion of its farm-in to Block 2B, onshore Kenya. Its subsidiary, Tower Resources (Kenya), has agreed to acquire a 15% interest in the block from Lion Petroleum, a subsidiary of Taipan Resources, which holds 40% of the licence. Completion was conditional on consent from Premier Oil group, which holds 55% of the licence. Tis has now been given. In February 2014, Taipan announced a 51-101 compliant independent assessment of Block 2B, completed by Sproule International, which estimated Block 2B, located in the Anza Basin, to hold gross mean unrisked prospective resources of 1593 million barrels of oil equivalent (mmboe), based on 19 exploration leads. Activity in the Anza Basin has also
increased. In Block 9, adjacent to Block 2B, Africa Oil and its partner Marathon Oil are currently drilling the Sala-1 exploration well, which will test a large prospect in the Cretaceous Anza rift system. Te results are expected later this year and the well is targeting gross risked prospective resources of 402 mmboe. Te recently acquired 2D seismic data across Block 2B is being used to determine
the drilling location of the first potentially play-opening well, Badada-1, which is expected to spud at the end of 2014/early 2015 and will target gross mean unrisked prospective resources of 251 mmboe – estimated by Sproule International. Finally, Tullow Oil has announced that
the Shimela-1 well in the South Omo Block, onshore Ethiopia, has encountered water bearing reservoirs. Shimela-1 was drilled to test a prospect
The discovery of the Kudu gas field and anticipated oil resources could help Namibia achieve greater energy self- sufficiency and reduce its dependence on imports, according to Frost & Sullivan.
“A breakthrough in the oil and gas sector in Namibia, which is relatively underexplored, holds enormous potential for the country,” says Energy & Environmental research analyst Muneera Salie. “If these resources are proven to exist, it could result in the country becoming one of the richest in Africa in terms of GDP per capita within the next five to 10 years.”
in a north-western sub-basin of the vast Chew Bahir basin. Te frontier wildcat well encountered lacustrine and volcanic rocks including almost 100m of net sandstone reservoir within siltstones and claystones. Trace thermogenic gas shows were recorded at 1,900m. Te Exalo 205 rig drilled Shimela-1 to a final depth of 1,940m. Te rig will now be moved to drill the Gardim-1 wildcat exploration well in a completely separate sub-basin, in the south-eastern corner of the Chew Bahir basin. Angus McCoss, exploration director,
Tullow Oil, commented: “Although the Shimela well only found traces of thermogenic gas, it has provided key data to build our understanding of the north- western part of the Chew Bahir basin.” In a separate development, Africa Oil,
Tullow Oil’s partner in Blocks 10BB and 13T in Northern Kenya has issued an update stating that the Twiga-2 sidetrack encountered 62m of net oil pay. l
Vallourec lands line pipes and welding services contract in Ghana V
allourec has been selected to supply premium line pipes and welding services for the TEN ultra-deepwater
oil and gas project, operated by Tullow Oil in Ghana, and executed by a consortium of Subsea 7 and Technip. Te TEN fields (Tweneboa, Enyenra and Ntomme) lie in
the deepwater Tano block, around 60km offshore Ghana. Te reservoirs are spread over 800km2
and lie in water
depths of between 1,000 and 1,800m. Under the contract Vallourec will provide 15,000 tonnes of anti-corrosion coated pipe to Subsea 7. Te pipes will then become dedicated production flowlines using ITP’s pipe-in-pipe system. Vallourec’s subsidiary Serimax, an international welding
company, will carry out the associated welding services for the double jointing operations related to the production pipe-in-pipe and the gas export lines.

Dominique Richardot, MD of Vallourec’s Pipe and SURF activities, declared: “Vallourec’s involvement in several parts of the TEN project demonstrates our ability to generate added value for our clients through flexibility, synergies and close cooperation. By providing an important number of non-standard pipe dimensions we help Subsea 7 facilitate the pipe-in-pipe design optimisation, and thus reduce total costs. Moreover, thanks to our lean logistics, our performing welding services, as well as our strong execution team, we offer a full support to our client to efficiently conduct this offshore project in Ghana.” Vallourec is a key supplier for Subsea 7 and has maintained this position through the successful delivery of line pipe products for the BG Knarr Project in Norway. It says that this new contract for the TEN Project reinforces the existing cooperation between the two parties. l
