Fugro has teamed up with Ikon Science to offer the market such a solution, a combined wellsite geohazard analysis and pore pressure prediction service, in a single integrated project. This is a partnership that will provide industry with efficiencies in time, cost and data consistency and significantly improved technical quality to reduce risk.
This integrated workflow approach will be particularly useful for wells in shelf to deepwater where data is limited and drilling is expensive.
Wellsite geohazard problems in many basins around the world are often pressure-related and regularly observed along the entire length of a wellbore, from subsea to the prospect. In the shallow section, before the first pressure containment string is installed, they manifest as shallow gas or shallow water flows, and in the deeper overburden, as drilling kicks and losses.
The integrated service will see the sharing of all input data and analyses, including the high resolution seismic data that forms the basis of Fugro’s work and petrophysical logs that much of Ikon’s work depends on. Ikon will make use of Fugro’s detailed seismic interpretation and analysis of shallow section conditions to enable a more complete and accurate study of pore pressure. In turn, Fugro’s wellsite geohazard analysis will benefit from better quality log interpretation, providing refinement and enhancement of the geohazard interpretation.
As Steve O’Connor, Global Lead for GeoPressure at Ikon Science explains “One of the key benefits resulting from this new integrated service is the ability to provide a continuous unbroken set of pressure profiles from seabed to total depth.”
“The integrated workflow brings together multiple aspects of sub-surface geoscience and provides a better assessment of shallow section geohazards, many of which are pressure related," adds Richard Salisbury, Senior Consultant from Fugro GeoConsulting. "This approach will be particularly useful for wells in shelf to deepwater where data is limited and drilling is expensive.”
The offshore industry spends $60 billion a year on drilling oil and gas wells and an estimated 10%, or $6 billion, is lost on geological, geotechnical and pressure related problems.
