Tullow exits Liberia and Sierra Leone

On 30 July, Tullow published in H1 2014 results.

Within the results, Tullow stated:

"After evaluating potential options in Liberia and Sierra Leone, Tullow made the decision not to renew its licence interests and will exit its position. Tullow’s interest in LB-15 in Liberia expired in June 2014 and its interest in SL-07B-11 in Sierra Leone will expire in August 2014, following which Tullow will have no licence interests in either country"

Acreage map taken from Simba Energy for Liberia shows Tullow's acreage position in that country:

ISIS: Sectarian furies unleashed again

The recent events in Iraq is a continuation of a rift between Sunni and Shias that began over a thousand years ago

• Shias believed Ali, the son-in-law of the Prophet Muhammad should take over the leadership upon his death
• Sunnis believed the Muslim community should determine the new leadership by consensus
• Ali became the new leader, but upon his assassination in 661, war broke out between the two groups

Islamic terrorism once seemed to wear a Shi'ite face and put the US on the side of the Sunni Iraqi dictator Saddam Hussein

• In 1979 Khomeini, leader of the Iranian revolution, overthrew the pro-American Shah if Iran, Pahlavi
• Together with the Iran hostage crisis which saw 52 American diplomats and citizens held hostage between November 1979 and January 1981 made Iran an enemy of the West
• In 1983, when Shi'ite militant group Hezbollah bombed US marine barracks in Beirut (Lebanon) made the US side with Hussein
• The US also supported and trained jihadists, including Osama bin Laden, in their fight in Afghanistan against the Soviets
• Bin Laden believed that Allah had empowered him and his followers to establish a new caliphate
• The ambition became absolute Sunni authority and Sharia law over the Muslim world

Ivar Aasen crib sheet

• Contains 4 fields: Ivar Aasen, West Cable, Hanz, Asha
• PDO approved in March 2013
• Development costs relatively high
• Discovery of Asha in December 2012, and inclusion of Asha in development improves economics
• Edvard Greig and Johan Sverdrup could push cost of services market higher
• Ivar Aasen expected to receive transitional terms , whereas other fields will be taxed under new terms

Participation

• Ivar Aasen Area contains 3 licences
• Ivar Aasen/West Cable (PL001B)
• Hanz (PL028B)
• Asha (PL457)
• Field unitisation expected mid-2014
• Estimated unitised participations are: Statoil (41.15%), Det Norske (28.8%)*, Bayerngas (12.34%), Wintershall (7.08%), EON (3.54%), Spike (3.54%), Verbundnetz (3.54%)
• Note that on 25 June 2014, Det Norske increased its stake in PL457 (above unitisation does not reflect this)
• EON to receive 15% WI in PL613 (Barents) and 10% WI in licence PL676S (North Sea) + Cash
• Det Norske increases interest in PL457 from 20% to 40% WI

Reserves

• WM Commercial reserves: 149mmbbl + 181bcf
• Hanz: good reservoir – expect high RF
• West Cable: strong acquisfer support – expect high RF
• Ivar Aasen and Asha reservoir more complex, varying sand quality

 Production

• Ivar Aasen, Asha and West Cable production from 2016; Hanz in 2019
• High rates of gas production expected from some wells due to gas cap in Ivar Aasen and Hanz reservoirs
• Wells will be drilled in order that gas production can be shut off to maximize oil recovery
• Asha gas initially reinjected

Development

• Ivar Aasen, Asha, West Cable: developed using fixed platform
• 20 well slots with partial processing facilities
• Production and injection wells will be drilled using jack-up positioned next to platform to 2016/17
• Hanz will be developed using subsea tie back to Ivar Aasen platform
• Exports via Edvard Grieg facilities

Eagle Ford Shale

Intro and history

• Play in South Texas stretching into Louisiana; contributes c.10% towards US production
• Three “windows” to the play – oil, gas-condensate, dry gas; focus has been on development of the liquids section
• Eagle Ford formation not singled out until 2008 although routinely tested before then
• Initial production was gas/condensates by Petrohawk with Apache testing oil around the same time
• Big change in 2010: EOG acquired acreage in oil window, changing Eagle Ford into a liquids focused play

Well economics

• Production and reservoir quality varies greatly in Eagle Ford; EURs can range from 200mboe to > 1mmboe per well
• Drilling and completion costs: USD5.5-9.5m / well
• Early Eagle Ford wells were completed with 10-stage hydraulic fracs; now common for 15-20 stages

Infrastructure

• Ideally located to supply refineries in Corpus Christi and Houston
• Short distance to Gulf Coast refineries reduces costs and allows for more transport options (barges, pipelines, rail and trucks)
• Volume of crude, condensate and NGLs that require processing has led to the construction of several projects; trucks will continue as intermediate solution whilst projects are being completed
• Eagle Ford Crude Oil Pipeline (Enterprise Products): 350mboepd capacity with interconnections to Seaway Pipeline and the new 5mmbbl Echo Terminal in houston
• Kinder Morgan condensate pipeline: Eagle Ford to Pasadena, 300mbopepd capacity
• Koch/NuStar/Arrowhead: 200mboepd capacity
• Plains All American: Eagle Ford to Corpus Christi, 300mboepd capacity

Outlook

• Operators looking to increase resource potential through down spacing and testing additional formations

Bakken

Intro and history

• Spans western North Dakota, eastern Montana in US and parts of Saskatchewan and Manitoba in Canada
• Named after Montana farmland owner Henry Bakken
• Recoverable estimates continue to increase as more about the play is understood
• First production in 1951, after which, formation began to be mapped
• In mid-90s, Elm Coulee field discovered with significant oil accumulation in the middle Bakken member
• In mid-2000s, EOG drilled the Nelson Farms 1-24H well; demonstrated H-wells with fracture stimulation could produce high IPs
• In 2009, Continental Resources found that the Bakken and Three Forks formations were separate reservoirs and could be produced independently

Well economics

• EURs highly dependent on location: range 200 to >1,000mboe, average 450-650mboe
• Wells average USD9.5m to drill and complete, but can vary depending on length of lateral and material usage
• 10,000ft laterals and 40 fracture stages becoming common
• Implementation of pad drilling is reducing costs

Infrastructure

• c.65% oil shipped via rail; enables access to higher Gulf Coast sales prices (Light Louisiana Sweet “LLS”)
• 2012 production: >700mbopd vs. 2007 production: c.200mbopd
• Transporting to Gulf Coast has been economically more attractive than to the oil congested WTI hub at Cushing, Oklahoma
• Explosive growth meant existing inter and intra-state pipelines quickly reached capacity
• Within play, crude transported by truck
• Outside play, rail and pipeline used
• Rail (USD15-20/bbl) is more expensive than pipeline (USD8-9/bbl), but allows access to LLS pricing

Outlook

• Cost reduction
• Expand longevity of play by testing lower Three Forks
• Down spacing
• Secondary and tertiary recovery
