BP has announced the start of gas production from the Atoll Phase One project offshore Egypt. The project, in the North Damietta concession in the East Nile Delta, was delivered seven months ahead of schedule and 33% below the initial cost estimate.

The project is now producing 350 million cu ft/day of gas and 10,000 bbl/day of condensate. Gas production from the field is directed to Egypt’s national grid.

In other news, BP also announced two new exploration discoveries in the North Sea. The discoveries are Capercaillie, in Block 29/4e in the Central North Sea, and Achmelvich, in Block 206/9b West of Shetland. BP is 100% owner of Capercaillie, and the Achmelvich well partnership comprises BP (operator, 52.6%), Shell (28%) and Chevron (19.4%).

The Capercaillie well was drilled to a total depth of 3,750 m and encountered light oil and gas-condensate in Paleocene and Cretaceous-age reservoirs. The well data is under evaluation. Options are expected to be considered for a possible tieback development to existing infrastructure.

The Achmelvich well was drilled to a total depth of 2,395 m and encountered oil in Mesozoic-age reservoirs. Evaluation and interpretation of the well results is ongoing to assess future options.

Shell strikes significant oil find with Whale well in GOM

Shell has announced one of its largest US Gulf of Mexico exploration finds in the past decade from the Whale deepwater well. The well encountered more than 1,400 net ft (427 m) of oil-bearing pay. Evaluation of the discovery is ongoing, and appraisal drilling is under way to further delineate the discovery and define development options.

Whale is operated by Shell (60%) and co-owned by Chevron (40%). It was discovered in the Alaminos Canyon Block 772, adjacent to the Shell-operated Silvertip field.

In other news, Shell recently won several exploration blocks in Mexico’s Deepwater Round 2.4. The National Hydrocarbons Commission (CNH) awarded Shell four exploration blocks on its own, one with its partner Pemex and four with its partner Qatar Petroleum. Shell will be the operator of all nine blocks.

CNH awarded 19 of the 29 blocks that were offered. “We commend Mexico on a historical, successful bid round; for Shell, today’s win marks a competitive, deepwater entry in Mexico,” said Andy Brown, Upstream Director, Shell. “The proximity and technical similarity of this opportunity to our leading position in the US Gulf of Mexico will allow us to benefit from and build upon decades of experience, complementing our position in the region.”

Frigstad Offshore designs semi for ‘all water drilling’

By Eva Vigh, Editorial Coordinator

Frigstad Offshore has launched a project to build a new-generation, harsh-environment semisubmersible that the company says will be suitable for “all water drilling,” from 350 ft to 14,000 ft of water depth, “which would be the deepest currently rated in the world,” CEO Dag Frigstad said.

The Frigstad D90 AWD design, developed by affiliate Frigstad Engineering, is the third generation in the Frigstad D90 series, featuring two main drill floors that are independent of each other. Multiple tasks, such as drilling and casing makeup, can be carried out simultaneously and independently. “The focus is not on ultra-deepwater but on ultra-efficiency… We wanted to design a versatile unit that an oil company can take on for a long-term contract that can be used for all the relevant programs that they have,” Mr Frigstad said.

The rig design incorporates a hybrid power solution that runs on both a power-generation system and batteries, which helps to stabilize power consumption.   

The hybrid power solution will significantly reduce fuel usage and emissions, which makes the rig ideal for the European market, where environmental regulations are particularly stringent. “We’ve gone through the highest environmental accreditation we can with low emissions and using the least amount of fuel that we can,” Mr Frigstad said, adding that West Africa, the Gulf of Mexico and Brazil are also potential markets.

The company is also designing the rig so that it can be easily adapted for higher levels of robotics in the future, particularly on the drill floor. “Our ultimate goal as a rig designer is to be able to build a rig that can operate without people,” Mr Frigstad said. “This will not happen immediately, but it’s something that we have as a mission, and it’s being incorporated into the design.”

The Frigstad D90 design has been used to build three drilling rigs since 2006. The first-generation D90 design, the Scarabeo 9, was delivered to Saipem in 2011 and has since operated in Cuba, West Africa and the Black Sea.

Frigstad Group ordered the second-generation D90 rigs, the Bluewhale 1 and the Bluewhale 2, jointly with Chinese investors in 2012 before withdrawing from the investment in late 2016. The first of these units, the Bluewhale 1, recently completed its first drilling campaign in the South China Sea.

A tender for the new-design rig has been initiated with shipyards, possibly for two units initially and with various equipment options, according to Mr Frigstad.
