There have been remarkable changes within the oil industry over the past century. At the centre of this transformation are onshore oil rigs. Onshore oil rigs have maintained their wooden derricks while continuing to drive the global energy market while modernising to more automated, safe, efficient, and cost-effective drilling platforms. This article considers the history…
In the process of oil drilling, oil rig equipment is not only the basic tool for realizing drilling operations, but also the core element for ensuring the safety and efficiency of operations. As the exploration and development of oil and gas resources gradually advance into deeper and more complex strata, the requirements for the accuracy, reliability…
Logging is an indispensable technology in oil and gas exploration and production. Through downhole measurements, the obtained logging data can assist engineers in assessing formation properties, determining oil and gas reserves, selecting drilling routes and optimizing development strategies. However, the quality of logging data directly affects the accuracy of decision-making, and further influences the development…
The oil and gas sector has reached a point where the effective handling of data has transformed from being a competitive edge to becoming a main operational requirement. The industry produces daily large amounts of data that are complex, high-speed, and difficult to handle coming from various sources such as seismic surveys, drilling logs, real-time…
In today’s environment, there is growing pressure on oil and gas operators to realize more recovery, cut down non-productive time, and extend the life of their existing assets. As production from mature fields continues to dominate, workover operations have become a key lever to help sustain well performance. Yet choosing the right approach-especially from among the…
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…
