LONDON – Britain’s Oil & Gas Authority (OGA) is making more satellite and subsurface data available to support bids for the UK’s forthcoming 30th Offshore Licensing Round.
The focus on more mature areas of the UK continental shelf (UKCS), some of which were last offered for licensing over 40 years ago. The OGA claims it will be the shelf’s most significant offshore round in recent decades.
Newly released data includes:
• UKCS-wide multi-satellite gravity data (supplied by Getech)
• Around 1,000 wells with joined digital well logs (sourced by CGG and the OGA)
• Core analysis, formation pressure, and geothermal databases (from CGG)
• A report on the Upper Jurassic Sequence Stratigraphy and Sandstone Play Fairways of the Late Jurassic Humber Group of the UK Central Graben (from Geostrat)
• The first of a set of regional geological maps from the OGA’s regional geological mapping project, conducted by Lloyd’s Register, covering the central North Sea and Moray Firth areas**
• Formerly proprietary reports, provided by Shell and ExxonMobil, covering regional and subsurface aspects of the central North Sea, including individual operators’ experiences in low-cost well and completion design.
Gunther Newcombe, OGA’s Operations Director, said: “We want to help make the UK as attractive as possible to explore for oil and gas...
“The delivery of the first set of regional geological maps is a key milestone in what is a three-year project to deliver a consistent set of geological maps for the whole of the UKCS.”
All of the data packages can be accessed through the online maps on the OGA website which include an area of interest outline for each of the products, or via the OGA’s Open Data site.
The 30th Offshore Licensing Round should be announced later this year.
** The regional geological mapping project benefited from additional data sources used to help inform final maps and/or derive interpreted products, and include the21st Century Exploration Road Map initiative (21CXRM), PGS’ North Sea Digital Atlas, research data from Aberdeen University, and other products available via the British Geological Survey’s Offshore Geoindex.
Schlumberger, TGS, and BP provided additional seismic and well data for use within the project while Common Data Access supported the data delivery.
