Songa Mercur Spuds Spuds ENI’s Ca Ngu Well

Oct 24, 2013 – Neon Energy announced the spud of the Ca Ngu-1 exploration well in Block 120 offshore Vietnam. The objective of the well is to prove the presence of hydrocarbons in Pliocene clastic and Miocene carbonate reservoirs. Block operator ENI secured the Songa Mercur (mid-water semisub) to drill the well in 885 feet of water to a target depth of around 4,900 feet. If successful, the well could de-risk the nearby Rua Bien and Ca Lang prospects. Block 120 partners consist of ENI (50%), Neon Energy (25%) and KrisEnergy (25%).

Galoc-6H Flows at Expected Rate

Oct 24, 2013 – Subsea tree installation, well clean-up and flow testing of the Galoc-6H development well have successfully been completed at the Otto Energy-operated Galoc field. Galoc-6H flowed at a stable rate of 3,800 bopd on a 56/64-inch choke with a flowing tubing pressure of ~570 psi. These results were constrained by the testing equipment onboard the Ocean Patriot (mid-water semisub). Once tied into production facilities, Otto expects normal production from the well to reach 4,000 to 6,000 bopd. The 5H and 6H wells were drilled as part of the Phase II development plan which aims to increase field production to 12,000 bopd. Phase II production is scheduled to begin in November 2013.

Total: Significant Oil Find in U.S. Gulf of Mexico

Total announces a significant oil discovery at its North Platte prospect on Garden Banks Block 959 in the deepwater Gulf of Mexico. The discovery well encountered several hundred feet of net oil pay in Lower Tertiary sands which included several high-quality intervals.

Total estimates this discovery can have a potential of several hundred million barrels of oil. Further appraisal will be needed to confirm its size and commerciality.

“The North Platte discovery represents another example of Total’s bold exploration strategy targeting large exploration opportunities. It also demonstrates the efficiency of our alliance with Cobalt signed in 2009,” said Marc Blaizot, Total’s Senior Vice President Exploration.

Total is in a strategic alliance with Cobalt International Energy to explore for oil in the Deepwater Gulf of Mexico. The North Platte discovery is the first Lower Tertiary Wilcox formation well drilled by the Alliance. The results of the well confirm the northern extension of the Wilcox formation and the presence of liquid hydrocarbons. Therefore, this validates the major potential of this new exploration area of the Gulf of Mexico in which Total holds a substantial acreage position with several follow-on prospects.

North Platte is located in a water depth of approximately 4,400 feet (1,340 m) and was drilled to a total depth of approximately 34,500 feet (10,520 m).  Total holds a 40% interest in the North Platte discovery along with Cobalt (60%, operator).

Total Selects AGR’s RMR for Exploration Offshore Australia

TOTAL E&P Australia (Total) has signed up to use AGR’s Riserless Mud Recovery (RMR®) system.  The contract is for two exploration wells to be drilled over the next year in the Browse Basin off North West Australia.

Bernt Eikemo, AGR’s Vice President of the Enhanced Drilling Solutions (EDS) division (Asia Pacific), said: “AGR is delighted to be part of Total’s drilling team during the forthcoming exploration campaign. We hope that this is the start of a long, successful relationship with Total E&P Australia.”

He added: “Our previous experiences with several operators in the Browse Basin and the North West Shelf have shown that unconsolidated sand formations become much more benign when drilled with RMR® using a proper mud system.”

RMR® has been used by Total on several other projects internationally but this is the first time that the operator has used the system in Australia.

The main reason for using RMR® on these wells is to be able to drill through the unconsolidated sands of the Grebe Formation. It is renowned for stuck-pipe problems when drilling riserless using seawater and sweeps.

RMR® (system example attached) enables the use of weighted, engineered mud in the top-hole section. All mud and cuttings are returned to the rig with no discharge to the seabed. The top-hole section can be drilled more safely, quickly and with less impact on the environment.

RMR®, together with its sister technology the Cutting Transportation System (CTS™), has been deployed on more than 500 wells worldwide to date.

West Callisto Drills for Total Offshore Myanmar

http://d3n6f555sx1wcx.cloudfront.net/wp-content/uploads/2012/05/West-Callisto-Drills-for-Total-Offshore-Myanmar.jpg

Total recently started drilling operations offshore Myanmar at the Yadana field, using Seadrill’s jack-up rig, West Callisto.

According to the Seadrill’s Fleet Status Report for May, Total has hired the rig on a three-month contract. The contract, expiring in mid-July, will bring approximately $12 million to Seadrill.

Total operates the Yadana field (31.2%). Located on offshore Blocks M5 and M6, this field produces gas that is delivered mainly to PTT (the Thai state-owned company) to be used in Thai power plants.

The Yadana field also supplies the domestic market via a land pipeline and, since June 2010, via a sub-sea pipeline built and operated by Myanmar’s state-owned company MOGE.

Following the completion of drilling operations in Myanmar, the rig will leave south-east Asia in which it has been operating since 2010. West Callisto will move to Middle East to commence drilling operations offshore Saudi Arabia under a three-year contract with Saudi Aramco. The drilling program is scheduled to start in September 2012

Argentina’s shale potential at risk

April 14, 2012 10:27 pm by Jude Webber

Any hostile moves on YPF, the Spanish-controlled oil company, by the pro-nationalisation government in Buenos Aires could have implications that go way beyond the companies and investors at the heart of this bitter tug-of-war.

Why? Because Argentina is sitting on what geologists and energy experts widely agree is one of the world’s most attractive reserves of unconventional gas and oil – known as shale – which are trapped deep in the bedrock below ground.

Shale is potentially a very big deal indeed. It turned the US from energy importer to exporter – something that Argentina, which spent $9bn importing fuel last year, ought to take note of.

Argentina has about a third of the US shale reserves, but they are less deep (which makes them cheaper and easier to access), seams are two to three times thicker than in the US and, for now at least, Argentine shale is concentrated in the Vaca Muerta (Dead Cow) formation, rather than being spread out across the country.

So all other things being equal, shale producers should be brushing up their Spanish and heading south. Several big players – including ExxonMobil, Total and Apache – and smaller companies already have. But it is YPF which has the biggest acreage, and it estimates that as much as $250bn will be needed to develop a viable shale industry over the next decade.

No one’s pockets are that deep, so partnerships are the way to go. Except that regulatory concerns are raising red flags before investors’ eyes now.

YPF has been publicly criticised, stripped of a string of concessions after being accused of underinvestment and now the government is analysing how to give the Argentine state a bigger role in the company – something that, according to some proposals circulating in the government, could translate into the expropriation of as much as 50.01 per cent of the company.YPF is currently controlled by Repsol of Spain, which has 57.43 per cent, and 25.46 per cent is in the hands of the Eskenazi family’s Petersen Group. Just over 17 per cent is traded on stock markets.

So enthusiasm among potential new players in the shale sector – where some were prepared to invest as much as $10,000 to $12,000 per hectare, according to industry sources – is screeching to a halt. “This is damaging shale (prospects), of course,” Alieto Guadagni, a former energy secretary, told beyondbrics.

The government has been berating YPF for what it perceives as a failure to invest enough, yet the concerns its nationalization dream are raising risks reducing investor appetite – which is perverse. And if concerns over contracts were not enough to dampen investors’ spirits, the prospect of partnering with a state that likes fast results and dislikes repatriation of dividends may give pause for thought.

What is worse is that the shale prospects represent energy that Argentina badly needs. Underinvestment in the sector, analysts and industry players say, is the direct result of a regulatory regime that keeps prices in Argentina well below the international market.

As Guadagni put it, Argentina pays domestic gas producers some $2.8 per million British Thermal Units, yet shells out some $11 per million BTU for gas from Bolivia (produced, ironically, by Repsol YPF), and some $17 for liquefied natural gas to plug its huge energy deficit.

Meanwhile, the cost to Argentines for their domestic gas is about 50 US cents per million BTU of gas, and drivers of vehicles that run on compressed natural gas pay around $1.

“The big question is whether these plans for YPF will improve or worsen Argentina’s prospects for recovering its energy self-sufficiency,” Guadagni said.

Argentina had a $3bn energy surplus in 2006. This year, Guadagni reckons the deficit will be $6bn to $7bn, ballooning to $12bn in 2013. Argentina’s policy of cheap domestic energy to stoke demand and economic growth worked well after the country’s default of nearly $100bn in 2001. But it isn’t working now.
