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…

The oil and gas industry has always been one of the most complex, high-risk sectors in the world. Traditionally, new engineers, operators, and technicians relied on classroom lectures, manuals, and hands-on field exercises. Whereas these methods have some merit, they often have significant limitations in scalability, repeatability, and safety. Increasingly over the past few years,…

Oil and gas industry operation needs hands-on experience, but real-world drilling is risky and costly. That is where the drilling rig simulator comes in: a safe, controlled virtual environment that replicates actual rig operations, which allows trainees to develop practical skills, respond to emergencies, and gain confidence before going to work on a real oil…

Geothermal drilling is gaining attention in the oil and gas industry, even though it is primarily considered part of the renewable energy sector. Geothermal energy is seen as a potential ally for traditional oil and gas operations. Due to technological improvements and the oil and gas industry’s incessant quest for new energy sources to enhance operational…

Casing while drilling (CWD) combines drilling and casing installation in one operation, drilling while simultaneously installing casing, a technique used in the oil and gas sector, and has a huge potential impact on wellbore construction, especially in difficult drilling and formation environments. What is Casing While Drilling Casing while drilling combines the operations of drilling…

Safe and economic storage and transportation of oil and gas is the backbone of the global energy market. From the production location to the refinery and end-user, every operation in the supply chain must be regulated with care to prevent accidents, harm to the environment, and operational delay. Advances in technology, regulatory policies, and innovative…

An oil rig installation is one of the most technically demanding operations in the energy industry. Not only does it require advanced engineering skills, but also precise coordination between different disciplines—from civil and mechanical engineering to safety management and logistics. Each oil rig installation, whether offshore or onshore, is a major investment that directly affects the…
