Fibre optic monitoring and finite element analysis of well integrity in methane hydrate reservoirs
Well integrity is crucial for sustainable hydrocarbon production from oil and gas reservoirs. The number of new wells can be minimized by maintaining the integrity of existing wells. Also, oil and gas leakage due to compromised well integrity can be curtailed through proactive well integrity …

Well Integrity Mapping Using Hybrid Model Based on Physics of Failure and Data-Driven Methods
… of H2S in high pressure and high temperature wells with pressures greater than 15,000 psi or temperatures of 350 °F can lead to strength reduction of casing strings and advance the time to failure. Casing strings also get damaged during drilling. The objective of this study is to develop a …

Enhanced oil recovery simulation study for Citronelle field, Alabama
… fractures that affects flood performance, as well as operational issues - down-hole pumps, well integrity, and difficulties with data collection due to the mixing of "power oil" with produced oil - which will need thorough consideration.

Reactive MgO and Self-healing Microcapsules for Enhanced Well Cement Performance
… cement sheath plays a crucial role in ensuring well integrity by providing adequate zonal isolation, stabilizing the formation, and protecting the casing from corrosion. A majority of well integrity problems originate from oil well cement shrinkage and shrinkage-induced cracking, as well as …

Real-time monitoring of cement sheath integrity under high-angle HPHT wellbore conditions.
The lengthy time span over which the cemented well needs to retain its integrity is a massive challenge today. The cement plugs in abandoned wells, in conjunction with the annular cement sheath, need to prevent leakages well beyond the life of the wellbore. The results of a recent engineering study …

Characterizing the Behavior of Smart Oil Well Cement for Enhancing the Monitoring of Cement Sheath Integrity
Oil well cementing is one of the most important and yet complex steps of a drilling project. One of the challenges in maintaining the well integrity is in monitoring the performance of oil well cement (OWC) used in the construction of the well. Recent oil well failures have clearly identified the …

Evaluation, Prediction, and Monitoring of Methane Emission from Oil and Gas Development
… negatively correlated with the distance to O&G well in one of our study regions, but such correlation was confounded by topographic variation. Furthermore, dissolved sulfate concentration was negatively correlated with methane concentration and with distance to coal mine, and these correlations …
