Cost Transformation 2

Enhanced Well Chemistry and Integrity (CTR2)

The objective of the Enhanced Well Chemistry and Integrity programme is extension of commercial field life by reduction of well related OPEX and downtime. This will be achieved by enhanced methods for corrosion and scale prediction and mitigation. Also, all methods will be integrated into a probabilistic risk management predictive tool for planning of well interventions.

This program consists of four specific research areas related to well integrity and flow assurance. The areas of inorganic scaling, corrosion and reservoir souring are interrelated in the well. While they all may provide independent enhancements, we also envision that all will contribute to an improved understanding and qualitative and quantitative input to the fourth pillar, namely probabilistic risk management. Probabilistic risk management aims at making predictions about the impact that the three flow assurance problems, inorganic scaling, corrosion and reservoir souring, may have on well failure. Also, using this in maintenance planning could lead to increased efficiency, lower cost, and less lost production of oil.

The four areas contribute to the verification of the overarching hypotheses of the program. Read more about the research areas by clicking the links below:

DHRTC Hypotheses

The three main hypotheses in this programme are:

  • Well OPEX can be reduced through proactive intervention activities by applying a probabilistic risk management predictive tool
  • Risk uncertainties can be reduced by introducing state-of-the-art models of corrosion, scaling and souring mechanisms
  • Well uptime can be increased through activities to mitigate corrosion and scaling, thus increasing well integrity

Pertaining to these  are five key prototypes:

  • Probabilistic risk management tool for well intervention
  • Improved Prediction of Soft Scale Formation and UDC in vertical well section
  • In-well Corrosion Prediction and Mitigation
  • Reservoir Souring: prediction and mitigation
  • Improved Prediction of Barium and Strontium Scale Formation

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.
