UK Continental Shelf at a crossroads

Alexander G. Kemp

The UK Continental Shelf (UKCS) is at a crossroads in its long-term evolution, as recent measures of activity present a mixed picture. Production has been falling at a brisk pace, reaching 1.45 MMboed in 2013. This is far below the peak of 4.5 MMboed in 1999. This is due to several factors, particularly the natural and inevitable decline in output from mature fields, the falling, average size of new field discoveries and development, and the fall in production efficiency. Production efficiency is the ratio of output to the maximum attainable rate, taking into account the need for regular maintenance. This ratio has fallen from 81% in 2004 to 61% in 2012, and reflects the substantial increase in downtime from technical problems in producing facilities. This problem is present in very old, and not-so-old, platforms.

Chevron in 2015: A few insights

Ben Bloys

As I sit down to consider 2015, Chevron’s upstream portfolio is poised for continued growth through projects around the world. Our resource base is large and diverse, providing us flexibility to react to market conditions. We have a strong balance sheet and the capacity to fund attractive growth opportunities—even in times of lower crude prices.

2015: More politically friendly, but less economically secure

John T. Rynd

Like every year, 2015 will bring its share of surprises and unpredictable events. A year ago, the politics of the mid-term elections dominated much of the energy-related discussion. Notice I said “discussion,” because decisions were hard to come by, with a divided Congress and White House.

Role of class in deepwater regulatory compliance evolves with industry needs

Bret Montaruli, Luiz Feijo

As activity accelerates, regulatory compliance in the deepwater Gulf of Mexico touches more and more of the supply chain. Increased emphasis is being placed on the certification of new technologies not deployed previously in the region.

North American outlook: Prosperity in the U.S. market continues

Kurt Abraham, Robert Curran, Mauro Nogarin

Despite a variety of interfering factors, U.S. activity remains at a high level, aided by the industry’s technical and efficiency gains. Canada continues to slowly rebound on the strength of oil activity, while Mexico remains at a lower level.     

Regional report: West Africa

Laura White, Arran Waterman

Identification of potential pre-salt basins and improved deepwater technologies leads to targeted licensing rounds, as several countries strive to participate and boost activity in these frontier plays.

Energy, security and understanding the human terrain of West Africa
