BPZ Energy,an independent oil and gas exploration and production company, announced that the hull tower for the CX-15 platform was successfully floated off the transport vessel, uprighted and ballasted. Subsequently, the topside facility was also successfully mated to the hull tower.
The CX-15 platform is now anchored at the West Corvina field location, one mile south of the existing CX-11 platform.
Welding and other miscellaneous activities are underway and will take approximately two weeks. The Petrex-28 drilling rig, which has been inspected and accepted for work, will then be mobilized to the CX-15 platform. It is expected that the necessary environmental permit required to conduct drilling operations from the CX-15 platform will be received from the Peruvian authorities before the drilling rig is mobilized. The Company expects to spud the first well of the CX-15 drilling campaign in late October.
The CX-15 platform was safely completed and successfully delivered to BPZ Energy at Wison Offshore & Marine’s Nantong, China, fabrication facility in a record 11 months from contract signature and without a single lost time incident. Wison’s scope included the engineering, procurement and construction of the facility’s 2,500 ton Buoyant Tower hull and 1,500 ton topsides facility. This project represents not only the first use of the design, but also the first implementation of Wison’s integrated international delivery model including members from the company’s three operation centers Inc. located in Shanghai and Nantong, China, and Houston, Texas, USA.
The Buoyant Tower hull for the facility was designed and engineered through a joint venture between Wison affiliate, Horton Wison Deepwater, and GMC Limited and consists of four, ring-stiffened connected cylindrical tubes or “cells” with one central suction pile. Each cell measures 8.4 meters in diameter and 60.1 meters long, with a total hull length, including suction pile, of 69.9 meters. This design, which is similar to proven cell spar technology, was a key enabler for the project due to the fact that it will not require a derrick barge for installation as it is located in a region with minimal resident offshore construction vessels.
Drilling of the first well in the long-awaited exploration of Cuba‘s offshore oilfields has gone slower than expected, but should be completed by mid-May, according to reports.
Reuters quoted sources close to the project as saying drillers had encountered harder rock beneath the sea bed than expected, which combined with other minor problems, had slowed progress.
When drilling began on 1 February Spanish oil giant Repsol YPF said drilling of the deep-water well was anticipated to take about 60 days to complete.
A Repsol spokesman could not confirm on Friday the projected mid-May completion date, when contacted by Reuters.
This well, which is in 1706 metres of water off the communist-run island’s north-west coast, is the first of five currently planned, Cuban officials say.
Cuba has said it could have 20 billion barrels in its offshore fields. It needs the oil to end its dependence on Venezuela, which ships it 114,000 barrels a day.
Cancer-stricken Venezuelan President Hugo Chavez is Cuba’s top ally, but island leaders worry that the oil flow could stop if he dies or loses his bid for re-election later this year, Reuters reported.
The US Geological Survey estimated Cuba may have 5 billion barrels of oil and 10 trillion cubic feet of natural gas offshore, but its study covered only part of the Cuban zone.
Reuters cited various unnamed sources as saying Repsol had been encouraged by its findings thus far, but the company has said results will not be known until the well is finished and studies are conducted.
Oil experts say it will take three years or more to bring the Cuban oil on line, if enough is found to justify production, according to Reuters.
After Repsol completes its well, it will hand the Scarabeo 9 drilling rig over to Malaysia’s state-owned Petronas and its Russian partner Gazprom Neft for a second well.
Then it will go back to Repsol, which has a consortium with Norway’s Statoil and ONGC Videsh, a unit of India’s ONGC, for another well, Reuters reported.
The massive Chinese-built rig, which is more than 32 kilometres offshore but visible from Havana, is being leased from owner Saipem, a unit of Italian oil company Eni.
Due to the longstanding US trade embargo against Cuba, no American oil companies are involved in the project.
Repsol drilled a well in Cuban waters in 2004 and found oil, but said it was not commercially viable. Technological limitations imposed by the embargo made it difficult to find another rig for work in Cuba, industry sources have said.
The project has raised environmental concerns in the US, particularly in Florida, which is 145 kilometres north of Cuba and fears its shores could be damaged if there is an accident similar to the BP oil spill in the Gulf of Mexico in 2010.
The Ministry of Commerce, People’s Republic of China, has granted consent to British Petroleum (BP), for an exploration drilling in the South China Sea in partnership with CNOOC, China Daily reveals today.
BP and the block operator CNOOC signed a deal for the exploration at the 43/11 deepwater block in South China Sea in January last year, but the agreement was subject to the Government’s approval.
This is BP’s second project in the deep waters of South China Sea after it had bought a stake in the Block 42/05 from Devon Energy China Ltd., in September 2010.
Asked when the exploration drilling would begin, BP China President Chen Liming told Reuters: “When we start depends on many factors, such as whether the drilling rig is ready. We hope to start drilling there by the end of the year.”
BP has been operating in China since the early 1970s and has business activities which include offshore gas production, chemical joint ventures, LPG import and marketing, oil product and lubricant retailing, chemicals joint ventures manufacturing ,technology licensing etc. According to China Daily, the British oil giant has so far invested more than USD 5 billion into China.

Chevron Corporation said that an extensive search and rescue effort continues for two contractors who remain missing after a fire aboard the K.S. Endeavor, a drilling rig offshore Nigeria operated by FODE Drilling Nigeria Limited.
“While Chevron s highest priority remains the rescue of the missing contractors, the company continues to devote the necessary resources to resolve the rig incident in a responsible and timely manner.” said Chevron in a press release.
As previously reported, the K.S. Endeavor was drilling a natural gas exploration well for Chevron Nigeria Limited (CNL). The well is located in the Funiwa Field approximately six miles (10 kilometers) offshore and in approximately 40 feet (12 meters) of water.
Chevron reported that 152 workers on the rig and an associated barge were safely evacuated. They are now onshore and have been given medical examinations. Two remain hospitalized due to minor burns, while others are being held for further observation. .
While a full investigation is still underway, Chevron said initial indications point to the possible failure of surface equipment during drilling operations that led to a loss of well control. The well continues to burn and the rig has partially collapsed. At this time, the company cannot estimate how long the fire will continue.
Chevron has contracted with and is mobilizing the Transocean rig Baltic to commence drilling a relief well. Chevron said the time required to complete the relief well is uncertain, but could extend for some period. Chevron is deploying additional drilling experts and well control specialists to Nigeria to assist with well control efforts and the relief drilling process.
A small sheen is visible in close proximity to the well, which the company continues to evaluate. The sheen is estimated at approximately 13 barrels. Production from Chevron s North Apoi platform remains shut in since it is situated in close proximity to the incident. Total production from the platform was approximately 2,000 barrels per day.
CNL owns a 40 percent interest in the well and the Nigerian National Petroleum Corporation has a 60 percent interest.

(Reuters) – An oil drilling rig with 67 crew on board capsized and sank off the Russian Far East island of Sakhalin when it ran into a storm while being towed, and 51 of the crew were unaccounted for, Russian news agencies reported on Sunday.
Fourteen crew members were rescued alive from the ‘Kolskaya’ jack-up rig, operated by Russian exploration company Arktikmorneftegazrazvedka, two bodies were recovered and the rest of the crew were missing.
“According to reports from the scene of the rescue operation, the Kolskaya platform has sunk completely,” the local head of the Emergencies Ministry, Taimuraz Kasayev, told a news briefing in Yuzhno-Sakhalinsk.
Agencies quoted officials as saying the rig capsized at about 0200 GMT on Sunday around 200 km (125 miles) off the coast of Sakhalin as it was being towed from the eastern peninsula of Kamchatka.
It appeared that the vessel had not been doing drilling work, so no oil spill was likely. The rig’s destination was not immediately clear.
While less serious that BP’s Macondo disaster, when a blowout caused oil to spew for months into the Gulf of Mexico, the fatal accident will deal a blow to Russia‘s efforts to step up offshore oil and gas exploration.
Russia has two major offshore projects that are already producing oil off Sakhalin – Sakhalin-1, operated by Exxonmobil and Sakhalin-2, in which state-controlled gas export monopoly Gazprom has a controlling stake.
State-controlled Rosneft this year reached a major deal with Exxon to explore for oil and gas in the Arctic Kara Sea.
