The decision between these methods affects well integrity, production potential, and operational safety. This comparison highlights the distinctions, benefits and considerations associated with underbalanced and overbalanced drilling. Understanding Underbalanced and Overbalanced Drilling Underbalanced Drilling…

In the oil and gas industry, drilling operations often take place in challenging geological formations. Air drilling is one technique commonly used to overcome such challenges, especially when dealing with rock formations that are either too unstable for conventional drilling fluids or too permeable, causing loss of drilling fluids. History of Air Drilling in Oil and Gas…

In contemporary oil and gas drilling operations, technology is essential for maximizing efficiency, safety, and productivity. Among the various tools and systems employed, mud logging stands out as a critical component of the drilling process. Mud logging monitors well conditions during drilling, offering vital data that supports decision-making and ensures peak performance throughout the operation. This…

Underbalanced drilling has become increasingly valuable in both offshore and onshore settings due to its benefits in preventing formation damage, reducing drilling fluid loss, increasing production rates, etc. However, the applications, challenges, and advantages of UBD drilling differ significantly between offshore and onshore drilling environments. Here’s an in-depth analysis of how underbalanced drilling functions in these two settings and what operators…

In reservoir engineering, understanding the physical properties and mechanical behavior of subsurface formations is crucial for optimizing oil and gas production. Geomechanics, the study of how geological formations respond to stresses, pressures, and deformations, has become a vital discipline in reservoir engineering. By applying geomechanical principles, engineers can gain insights into how rocks and fluids interact…

The global demand for energy continues to rise, necessitating innovative solutions to maximize oil recovery from existing reservoirs. Microbial Enhanced Oil Recovery (MEOR) emerges as a promising technology that leverages the power of microorganisms to enhance oil production. By introducing specific microorganisms into oil reservoirs, MEOR can significantly boost oil recovery, making it a valuable tool for…

Well completion in oil and gas is a critical process that prepares a well for production. Among the most common completion types are open-hole and cased-hole completions, both suited to specific well conditions and project goals. Choosing the right method is essential, as it affects not only the efficiency and longevity of the well but also…

Pipelines play a critical role in transporting crude oil, natural gas, and refined products over long distances.
