Treatment evaluation at the laboratory level was conducted to determine the effectiveness of two fluid recipes: acid- and chelating-based, to remediate formation damage caused by high-density barite (BaSO4...

... and recovery. Sanding evaluations are commonly calibrated against either surface sand observations, hole fill events, hold up points or rock mechanical simulations. Although advanced geomechanical and petrophysical analyses can identify the likely sand producing intervals, in the absence of direct...

... Abstract Pulsed neutron logging can be used for evaluating shallow gas hazards before initiating new infill drilling projects. The evaluation can be performed in existing platform through completed wells; however, the use of conventional pulsed neutron tools in old wells with multiple casing...

... and reliability of these tools for open hole formation evaluation and geosteering has propelled an entire sequence of highly complex and highly deviated wells with enormous improvements in productivity from existing fields. You would be hard pressed to find any wells, particularly in the offshore domain, that do...

... provides a methodology for assessing estimation algorithms and a scenario for deploying machine learning techniques to reliably forecast the condensate RVP for a production facility. Several RVP prediction approaches are used to evaluate the accuracy and field optimization prospects. Machine learning...

... Abstract Evaluation of the annular barrier is an integral part of well construction, integrity, and reentry scope. The current industry practice is to run sonic and ultrasonic tools to evaluate the barrier quality across a single string. However, many wells require the evaluation of the barrier...

...Caprock Integrity Evaluation Abstract One of the efforts to reduce the impact of climate change is by reducing carbon dioxide (CO 2 ) emission through carbon capture and storage (CCS) operation. As part of CCS feasibility study, geomechanical risk analysis is conducted on the field...
