Wireline logging helps gather important information concerning underground formations. In the oil and gas sector, wireline logging, especially, contributes to capturing data within the subsurface structures, even the unconventional resources like oil shale, tight sands and coalbed methane. Even though wireline logging assists in capturing subsurface data, it still faces restrictions, particularly within unconventional resources. These…

The oil and gas industry relies on well logging to provide vital data about geological formations and fluid properties. It also provides information about the overall characteristics of the well. Well logging is expensive due to the complexity of equipment, the data acquisition and the time needed for detailed measurements. Optimizing costs in well logging is a key goal…

As oil and gas operations become increasingly complex and more automated, the industry continues to grapple with one ongoing challenge: making sure that personnel at all levels-from rig crews to control room operators-have the situational awareness and technical competence to operate safely. Risk, cost, and field conditions limit real-world training opportunities. This is why high-fidelity…

During the drilling of oil and gas wells, casing and cementing are two vital operations that maintain the integrity and safety of the well throughout its productive life. The two processes work together to mitigate the risks of fluid migration, wellbore collapse, and groundwater contamination. The article analyzes the importance, techniques, challenges and technical innovations associated with casing and…

When discussing segments of the global energy infrastructure that focus on oil transportation, one should keep in mind the movement of crude oil and the operation of transport and consumer distribution services that cover refined petroleum products. With that said, the movement of oil by means of a pipeline, train, or truck constitutes a transport…

In the deepwater environments, well intervention is important for sustaining the production and the performance of offshore oil and gas wells. Operators deal with perplexing well integrity challenges as exploration moves into deep waters over 1500 meters. Maintaining production and managing mature fields is also an important component. Deepwater well intervention requires specialized tools, vessels,…

The development of deep and complex reservoirs has become increasingly challenging as operators move toward tighter formations, HPHT environments, and depleted zones. These wells require precise pressure control in both drilling and intervention phases. Two technologies have proven particularly valuable in addressing these challenges: Managed Pressure Drilling for dynamic BHP control during well construction and snubbing…

The landscape of energy production has always been subject to changes, and on the frontline of change has been the evolution of shale gas drilling. What was once a truly ground-breaking technique has matured into a sophisticated engineering discipline. Innovations driving modern shale drilling operations are not just boosting efficiency and output but crucially addressing…

The wellbore stability is vital because it contributes to the safety, efficacy, and economic viability of the drilling efforts in the oil and gas sector. Wellbore instability is dangerous because it can result in the wellbore collapsing, becoming stuck, or losing fluid. All of these consequences are costly and time-consuming to rectify. Wellbore stability analysis enables the…
