Cost Transformation 2

Maintenance Modularization and Well Performance Optimization

Cost Transformation 2 (CTR 2)
Technology Readiness Level 0

The Gorm field operation has a particular urgency in providing innovation to delay Cessation of Production (CoP). The DUC Gorm Late Life project has identified the main opportunities to reduce the Unit Technical Cost (UTC) by improved maintenance scheduling, reduced well maintenance cost, and rebalancing of infrastructure portfolio.

The opportunity identified by the DHRTC is to support the DUC by adapting best practices from the manufacturing industry to the operation and maintenance discipline, significantly reducing technical uncertainty associated with activities with greatest impact on schedule stability.

DHRTC Hypothesis

The main goal is to obtain extension of commercial field life by 5 years by a 40% reduction in base case OPEX. This will be achieved by optimized operational management and enhanced well health control / treatments resulting in reduced oil production loss, reduced water production as well as improved water injection. Secondary benefits will be enhanced reservoir sweep.

Main hypothesis:
Modularization of maintenance practices to identify “best of breed” and enable further improvements.

Supporting hypotheses:

  • Deterministic and probabilistic characterization of mission critical deterioration mechanisms for systems and structures.
  • A priori causal models for diagnostic of all critical deviations from intended performance of systems and processes to enable predictive maintenance and machine learning.
  • Optimization of facility uptime and reservoir sweep by combining mitigation of root causes with deployment of digital oil field methodologies.

The Transformation of Asset Cost group is subdivided into 4 work packages:

Expected Key Deliverables at TRL 3

  • Cost reduction by 4D maintenance planning
  • Skjold pilot test
  • Well intervention planning tool 
  • Establish test facilities and validate scale and corrosion mitigation techniques

Technology Readiness Level

The Technology Readiness Level (TRL) scale is used to measure the maturity of a project. All technologies are evaluated on the same basis of Comparison, which provides a better overall picture. The first step on the scale is research still in the idea phase while step 7 is where the idea has matured into applicable technology.
