50-YEAR ANNIVERSARY - The history of offshore -- Predicting its own growth and exceeding it - While three-fourths of the earth's surface is covered by water, the offshore petroleum industry has made its way from modest beginnings in the Gulf of Mexico to a vibrant, necessary industry, with a presence on practically every continental shelf and in every ocean of the world, excluding Antarctica. Ever since the first issue of Offshore Magazine in April 1954 -- A half-century ago this year -- The magazine's editorial and advertising content has reflected the absolute certainty with which the industry has predicted its own growth, and then has exceeded it.
GULF OF MEXICO - Forecasters expect more caution in GoM drilling - In 2004, operators will be more cautious in what they drill, and they will work to build up reserves in areas where production is already onstream.
GULF OF MEXICO - 2003 yields 17 deepwater GoM discoveries - Independents and supermajors drilled, and the hydrocarbons showed up -- In 17 discoveries in the deepwater Gulf of Mexico.
GULF OF MEXICO - Gulf of Mexico 'trouble time' creates major drilling expenses - Hole problem incidents, or "trouble time," have consumed 24-27% of Gulf of Mexico operators' drilling budgets from 1993 to 2002. This proportion brackets the general "authorization for expenditure fudge factor" of 25% many drilling engineers use when preparing well plans.
GULF OF MEXICO - Turnkey drilling model bucks decline trend - Rig counts in the Gulf of Mexico may have dipped from last year's rates, but turnkey operator Applied Drilling Technology Inc. isn't reflecting that drop.
MANAGEMENT & ECONOMICS - Online bidding solves some problems as it creates others - The goals seem sound -- Increase transparency, level the playing field, make bidding on projects more competitive -- But the trend toward online bidding has some contractors worried that operators don't see the whole picture.
GEOLOGY & GEOPHYSICS - Ekofisk seafloor seismic test proves the concept - In the fall of 2002, ConocoPhillips installed and tested a new seafloor seismic technology over the Ekofisk field using a prototype system developed by Input-Output. The objective was to verify that reliable full wave field seismic data could be recorded over the field.
GEOLOGY & GEOPHYSICS - Regional salt provinces evaluation aids future exploration - Each province in the Gulf of Mexico exhibits a unique salt inflation-deflation history that differs from adjacent provinces. As a result, each province has a unique a set of predictable structural styles, trap-types, and deep chrono-stratigraphic objectives. Therefore, drilling targets beyond 25,000 ft will vary from one province to the next. This article outlines criteria for high-grading areas in the Gulf of Mexico based on timing of canopy emplacement, salt system type, and salt-sediment balance.
PRODUCTION - UK's first abandoned oilfield restored to active service - Production has resumed at Ardmore in the central North Sea, 11 years after the taps were switched off. This is the first attempted resurrection of an abandoned field in the UK sector, using an entirely different production system. If successful, operator Tuscan Energy will have taken reservoir revival to a new level.
DRILLING & COMPLETION - Deepwater isolation, shallow-water flow hazards test cement in Marco Polo - Cement integrity achieved in the Gulf of Mexico Marco Polo development in Green Canyon block 608 is putting innovative slurry systems on the map of sought-after technologies for deepwater plays.
BEYOND THE HORIZON - Storm clouds gather - The storm clouds that were already gathering over the oil and gas contracting industry have darkened somewhat. There can't be many industries where clients are so wealthy and contractors so poor.
