Software-Driven Monitoring Approach Optimizes Well Integrity, Reduces Costs
The authors of this paper describe a software technology that balances calculated well-integrity risk with the associated financial impact for an entire integrity-surveillance program.
In the complete paper, the authors introduce a model that provides risk-based financial optimization for surveillance programs. The model balances risk with financial investment to provide the asset owner with several optimization scenarios (at low risk and low investment) and ensures that surveys are not overdone. The example used to explain the model is one involving well-integrity surveillance. This example allows the oil operator to obtain a return on past investment made into collecting historical well-integrity data.
Several different kinds of well-integrity surveys are common in the industry, including the following:
- Wellhead-integrity surveys use pressure to investigate the functionality and pressure-sealing integrity of the wellhead tree valves.
