'Maersk Discoverer' finished well 62 days ahead of time

At the beginning of May 2015, the crew on-board the Maersk Discoverer reached a great milestone when they finalised their latest well two months ahead of time. The well was another East Nile Delta success for BP, discovering 50 m of gas pay in high-quality Oligocene sandstones. On 5th May, Maersk Discoverer completed the deepest well ever drilled in Egypt and the longest ever drilled in the Mediterranean Sea. What makes the well an even greater success is that it was drilled in 234 days, which was a staggering 62 days ahead of BP’s AFE target, thus creating a substantial cost saving.

BP makes gas discovery with Atoll-1

BP Egypt announced today another important gas discovery in the North Damietta Offshore Concession in the East Nile Delta. The “Atoll-1” deepwater exploration well, currently being drilled using the 6th generation semi-submersible rig “Maersk Discoverer,” has reached 6,400 metres depth and penetrated approximately 50 metres of gas pay in high quality Oligocene sandstones. Expected to be the deepest well ever drilled in Egypt, the Atoll well still has another 1 kilometre to drill to test the same reservoir section found to be gas bearing in BP’s significant 2013 Salamat discovery, 15 kilometres to the south. Bob Dudley, BP Group Chief Executive, commented: “Success in Atoll further increases our confidence in the quality of the Nile Delta as a world class gas basin. This is the second significant discovery in the licence after Salamat. The estimated potential in the concession exceeds 5 trillion cubic feet (tcf) and we now have a positive starting point for the next possible major project in Egypt after BP’s West Nile Delta project.” Commenting on the discovery, Hesham Mekawi, BP North Africa Regional President said: “The Atoll discovery is a great outcome for our second well in this core exploration programme in the East Nile Delta. It demonstrates BP’s continuous efforts to help in meeting Egypt’s energy demands by exploring the potential in the offshore Nile Delta. We are proud of our commitment to unlock Egypt’s exploration potential that requires large investments to utilise using the latest drilling and seismic technologies.” Atoll-1 was drilled in 923m water depth around 80km north of Damietta city, 15km north of Salamat and only 45 km to the north west of Temsah offshore facilities. BP has 100% equity in the discovery.

DSM to provide mooring services for 'Maersk Discoverer'

Deep Sea Mooring (DSM) has won the contract to provide a comprehensive range of mooring services to Maersk Drilling for its sixth generation, semi-submersible drilling rig ‘Maersk Discoverer’. DSM will now design, engineer and install the mooring system for the advanced rig. “This is the first time we’ve worked with Maersk Drilling and the first time we’ve undertaken operations in Egypt,” comments Åge Straume, CEO of Deep Sea Mooring. “So, it’s a very significant contract for us and allows us to demonstrate how our extensive experience of installing mooring systems in the harsh environment of the North Sea can be transferred to new territories.” DSM will take the project from conception to completion – designing the complete mooring spread, defining operational procedures, mobilising and demobilising all equipment in both Norway and Egypt, pre-installing the anchors prior to rig arrival, and hooking up the rig when it arrives on location. “This is a complex assignment,” he states, “with water depths of 930m entailing high loads and a need to design a robust, high-quality and streamlined mooring solution. It’s the kind of challenge our experienced team thrive on and one we’ve successfully tackled for leading players in the energy industry, such as Statoil, in the North Sea, and Husky Energy, off the coast of Newfoundland. It’s exciting to be given the opportunity to showcase our expertise with a new client of A.P Moeller-Maersk’s standing.” In addition, Bergen-headquartered DSM will provide all base operations and personnel for the mooring and hook-up task. Once in place, ‘Maersk Discoverer’, a GustoMSC DSS 21 rig capable of drilling to 10,000m, will work the BP prospect.

Kosmos Energy's FA-1 well is plugged and abandoned

Kosmos Energy (Kosmos) has announced that the company’s FA-1 well being drilled in Morocco, in the Foum Assaka Offshore block has reached a total depth of 3,830 meters and will be plugged and abandoned after failing to encounter commercial hydrocarbons. The well, which is the first in a series of play-opening wells designed to unlock the Agadir Basin, was drilled to test the salt diapir play concept targeting the Cretaceous interval in a combined structural-stratigraphic trap. This is one of several independent play types and fairways present in the Agadir Basin. Importantly, FA-1 encountered oil and gas shows while drilling and in sidewall cores suggesting the presence of a working petroleum system. The well has also provided key seismic calibration information and the well results will now be integrated into Kosmos’ ongoing petroleum system analysis; in particular, the assessment of charge and reservoir play risks, as well as the evaluation and ranking of trap types ahead of the next tests of this petroleum system in 2015 and beyond.

Kosmos Energy spuds FA-1 well offshore Morocco

Kosmos Energy Ltd’s (Kosmos) partner in the Forum Assaka area in Morocco Fastnet Oil & Gas Plc (Fastnet) has confirmed the spudding of the FA-1 well on the 16th March 2014. The FA-1 well is being drilled by Maersk Drilling’s ‘Maersk Discoverer’ semisub rig, has a planned target depth of 4,000m and is being drilled in water depths of approximately 600m. The well is expected to take up to three months to reach its total depth and test multiple objectives. The FA-1 well is estimated by Kosmos, to contain 360 mmboe of Pmean resources in its primary deepwater Lower Cretaceous reservoir objective. Fastnet is carried through its share of the drilling costs, subject to a gross maximum well cost of US$100 million, following the previously announced farm-out to SK Innovation, retaining a 9.375% net interest in the licence.

BP discovers gas in the Salamat well in Egypt

BP Egypt today announced a significant gas discovery in the East Nile Delta. The deepwater exploration well, named Salamat, is the deepest well ever drilled in the Nile Delta. It is the first well in the North Damietta Offshore concession granted in February 2010 and operated by BP. The well was drilled using the sixth generation semi-submersible rig “Maersk Discoverer”, owned by Maersk Drilling, in water depth of 649 metres and reaching a total depth of around 7,000 metres. The wireline logs, fluid samples and pressure data confirmed the presence of gas and condensate in 38m net of Oligocene sands in Salamat. Further appraisal will be required to better define the field resources and to evaluate the options for developing the discovery. Mike Daly, Executive Vice President Exploration at BP, commented: “Success with Salamat proves hydrocarbons in the centre of a 50-km long structure. With a hydrocarbon column in excess of 180 metres, the discovery increases our confidence in the materiality of the deep Oligocene play in the East Nile Delta.” Hesham Mekawi, BP Egypt Regional President said: “The Salamat discovery is a great outcome for our first well in this core exploration programme in the East Nile Delta. It shows our commitment to meeting Egypt’s energy needs by exploring the deep potential offshore the Nile Delta. Standalone and tie-back to the nearby Temsah infrastructure development options are currently being evaluated.” The Salamat discovery is located around 75 kilometres north of Damietta city and only 35 kilometres to the North West of the Temsah offshore facilities. BP has 100% equity in the discovery.
