TAO-1 well fails to find hydrocarbons

Tangiers Petroleum Limited (Tangiers) provides the following update on the TAO-1 exploration well located in the Tarfaya Offshore Block, Morocco. The TAO-1 exploration well has intersected the shallowest and secondary objective, Assaka. Based on currently available information, no hydrocarbon shows have been encountered. A full petrophysical evaluation of the Assaka objective will be carried out at section TD. Drilling operations continue as planned towards the primary and largest objective, Trident. The TAO-1 exploration well has been designed to test Trident at its optimal location. Tangiers’ interpret that success at Trident is not co-dependent on the results from Assaka.

Tangiers releases brief TAO-1 well update

Tangiers Petroleum (Tangiers) has provided the briefest of updates on the TAO-1 exploration well offshore Morocco, operated by Portuguese explorer Galp Energia. It told investors: “No major operational issues have occurred to date and the well is expected to intersect the Assaka and Trident objectives within 60 days from spud, as previously announced.” It gave no information as to the depth or the formation currently being drilled as TAO-1 has been designated a “tight well”, which means the data is being kept under wraps. Drilling began on June 26th and is targeting a huge hydrocarbon bounty of 758mln barrels of oil equivalent, or 190mln barrels net to the AIM and ASX-listed group. The TAO-1 well is located within a proven petroleum system and is next to the Cairn Energy and Genel Cap Juby heavy oil discovery. The well is the very definition of a company-maker, particularly when you consider the Tangiers has a market capitalisation of just under UKGBP30 million. A 110-metre oil column was discovered on Cap Juby; however, the crude was of the heavy variety, which is more difficult to extract and transport. Tangiers believes, because of the geology of the area, that it has a much better chance than its neighbour of discovering lighter crude.

Galp spuds TAO-1 well in Morocco

Tangiers Petroleum (Tangiers) has announced that drilling has begun on the Galp Energia-operated TAO-1 exploration well offshore Morocco. The ‘Ralph Coffman’ jack-up rig will test up to three stacked targets: Assaka in the Upper Jurassic; the main target Trident in the Middle Jurassic and will move on to TMA if the well is deemed a success. It is expected to take around two months to intersect the first two oil horizons. Tangiers owns 25% of the Tarfaya block that’s host to the TAO well, which is targeting a huge hydrocarbon bounty of 758mln barrels of oil equivalent, or 190mln barrels net to the AIM and ASX-listed group. The TAO-1 well is located within a proven petroleum system and is next to Cairn Energy and Genel Cap Juby heavy oil discovery. TAO-1 is the very definition of a company-maker, particularly when you consider the Tangiers has a market capitalisation of just under UK£28 million. A 110-metre oil column was discovered on Cap Juby; however, the crude was of the heavy variety, which is more difficult to extract and transport.

Tangiers Petroleum prepares to spud TAO-1 well

Tangiers Petroleum (Tangiers) expects the TAO-1 exploration well offshore Morocco to spud on or around June 15th 2014. The well is targeting 190mln barrels of prospective resources, and is being drilled in area with a proven petroleum system. Tangiers expects drilling operations to cost USD73 million in total. The TAO-1 well, will be drilled by Rowan’s ‘Ralph Coffman’ jackup rig. Tangiers has a 25% stake in the TAO well, whilst GALP has 50% and Morocco’s national oil company ONHYM has 25%, though its costs are carried through the exploration phase.

'Ralph Coffman' begins mobilisation to Morocco to spud TAO-1 well

Tangiers Petroleum (Tangiers) has confirmed work will get underway on its first Moroccan exploration well in mid to late June. This follows the mobilisation of the ‘Ralph Coffman’ jack-up rig, which will target a best estimate of 758mln barrels of the black stuff. The ‘Ralph Coffman’ has been in a shipyard in Egypt since the beginning of April 2014, but Tangiers confirms that the unit has now begun mobilisation to Morocco. Tangiers has a 25% interest in the block where the TAO-1 well is being spudded. The TAO-1 well is operated by Portugal’s Galp Energia, which has a 50% interest, with the remaining stake owned by ONHYM, the state-controlled oil company. Tangiers managing director Dave Wall described TAO-1 as a “highly attractive prospect for Tangiers' shareholders”. "It is a very large structure located in shallow water within a proven play fairway and adjacent to an existing oil discovery," he said. "All the ingredients required for exploration success are present in the region, giving Tangiers, and its shareholders, a good chance of success at TAO-1."

'Ralph Coffman' on track to spud TAO-1 well in Morocco

Tangiers Petroleum Limited (Tangiers) has announced that the TAO-1 well off the Moroccan coast is on track to be spudded in June 2014, after the Moroccan National Office of Hydrocarbons and Mines provided final approval to a farm-out agreement between Tangiers and Galp Energia (Galp). Under the agreement Galp will pay Tangiers US$7.5 million for reimbursement of costs associated with the well. Galp has hired Rowan’s ‘Ralph Coffman’ jackup to drill the TAO-1 well, with the unit due to arrive in Morocco in May, following completion of its current contract in Egypt.
