Exploration is a key area of Operators’ technology spend, as its applications offer a competitive advantage to Operators in finding new hydrocarbon resources.
Mature fields remain subject to obligations under MER UK such as shooting new seismic (4D) and improving reservoir characterisation.
Advances in seismic acquisition in previous years (high-definition broadband and ocean bottom nodes) are now complemented by the latest seismic processing and reprocessing techniques, which are awaiting more widespread application.
In addition, latest software including applications of machine learning are proving useful to increase accuracy and chance of success, reducing cycle-time and costs.
Seismic & Exploration technologies
Operators’ technology focus is increasingly on processing (and reprocessing) and subsurface modelling to increase value from acquired data to drive time and cost efficiencies
Interest in Exploration technologies is concentrated within a subset of Operators aligned to basin strategies and opportunities
7 Operators carry at least 5 Exploration technologies in their current Plans
Like in other technology areas, Operators focus primarily on deployable technologies, i.e. in Early Commercialisation or Proven stages
However, more than in other areas, Operators participate directly in the development or adaptation of over 50% of the Exploration technologies in their Plans
Readiness definitions: Early Development (TRL 1-4), Late Development/Pilot (TRL 5-7), Early commercialisation (TRL 8), Proven (TRL 9)
Fewer operators reporting high-definition broadband or OBN acquisition this year as these have become business as usual. Focus remains on continuously improving acquisition approaches (sampling density, frequency spectrum) resulting in enhanced imaging such as deeper imaging or fracture visualisation.
Advances in newer technologies such as DAS VSP continues along with ongoing efforts in cost reductions of acquiring time-lapse 4D seismic surveys. Autonomous node technology to potentially reduce cost and acquire data in spatially constrained environments.
