LONDON – Britain’s Oil and Gas Authority (OGA) has published daily production figures from UK offshore wells that have ceased production, some having been in service for more than 40 years.
The OGA expects the data to interest reservoir engineers investigating undeveloped hydrocarbons or potential offshore carbon capture and storage (CCS) sites. It provides insights into daily values for oil, gas, and water, and pressures and temperatures at wellheads and bottom holes.
It should also allow companies to identify differences between separate sections of a field, allowing them to estimate areas that could still be sufficiently productive to warrant a potential redevelopment.
Owners of UK fields that have ceased production since 2018 must provide the data: to date, the OGA has published information from over 20 fields and 140 wells.
Currently the UK’s longest-producing field is Viking B in the southern North Sea, which was onstream from 1973 to 2015.
