The control of well formation pressures safely and predictably is important in drilling operations. Although the BOP serves as a barrier, true pressure control happens at the surface-through the choke manifold system. The choke manifold system enables the operator to control annular pressure and influx behavior while maintaining bottom-hole pressure stability during kick circulation. Understanding how…
For a long period of time, oil drilling has been the backbone of the world’s energy supply, continuing to evolve as the dependency on value chains of oil has increased. In the early days, oil drilling relied on purely mechanical systems, however, with reservoirs becoming more complex and standards becoming more holistic, more value has been…
Tight gas reservoirs are one of the biggest frontiers in energy production today. These enormous resources are locked into rock formations of very low permeability, and their extraction is quite a technically challenging task. For drilling engineers and well site leaders, this complexity means primarily one thing: well control. Most conventional methods fail in meeting…
Well intervention in the oil and gas sector entails performing maintenance, repair and enhancement activities. Two common methods for well intervention are wireline and coiled tubing. Each option is different and has distinctive advantages, so it is important to understand their differences and common applications to optimize for specific well intervention tasks. What is Wireline for Well Intervention Wireline…
Operations involving workover and well intervention help aid the oil and gas industry by helping sustain, fix, and improve wells. Optimizing well productivity, preventing damage, and maintaining the safety of people and tools involved requires the use of a hierarchy of approaches and technologies. A major element in both workover and intervention activities is well control, which…
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…
