Offshore exploration is one of the most technically demanding fields in the global energy chain. As oil and gas development continues to move towards ultra-deep waters, choosing between a drilling ship and an offshore drilling platform (such as a semi-submersible or jack-up platform) is a core capital expenditure (CAPEX) decision that directly determines the safety…
Shale oil drilling has become one of the most significant changes in the global energy field during the last few decades. I mean, the pace of its expansion has kind of reshaped energy markets worldwide, and it also pushed oil and gas companies to change their strategies, fairly quickly. Still, shale oil drilling is not a…
Resistivity logging is critical in oil and gas exploration, as it gives helpful clues about what’s going on underground and what fluids may be sitting there. It’s also one of the most commonly used well logging techniques, so geologists and petroleum engineers can use it to spot likely hydrocarbon reservoirs, judge formation properties, and then…
Passing the well intervention test for an IWCF Level 3 (Driller) or Level 4 (Supervisor) qualification is difficult indeed. For a person who runs a training center or oilfield service company, this is an obvious statement. The thing is that the failure rate of practical exams is quite high. The main difficulty here is that traditional classroom training…
Nuclear Magnetic Resonance (NMR) logging is a key technology in the oil and gas industry. It breaks away from the limitations of traditional tools that rely on the rock matrix, directly interacting with hydrogen protons in the fluid, thereby providing geologists with more accurate data on total porosity, permeability, fluid type, and reservoir characteristics.However, in…
Today, well intervention using coiled tubing (CT) is a necessary element in any field development. Coiled tubing units provide operators with cost-effective tools for live-well intervention without the necessity to kill the formation. At the same time, this efficiency is accompanied by the reality that is very hard to underestimate: coiled tubing operations represent one of…
Managed Pressure Drilling (MPD) has emerged as a transformative method in modern drilling processes, especially for improving well control. In increasingly complex geological settings, such as deepwater, high-pressure high-temperature (HPHT), or depleted formations, conventional well control strategies often face limitations. MPD tackles these problems by allowing a dynamic control of the annular pressure profile while drilling, which reduces risk and increases operational efficiency….
Imagine a well as a long, intricate straw reaching deep underground to tap into a reservoir of oil and gas. Over time, this straw can become clogged, damaged, or simply less effective at drawing fluids. A well workover is akin to taking that straw out, giving it a thorough inspection and fix-up, and then putting…
Coiled tubing drilling (CTD) in oil drilling is a versatile and efficient method for drilling and completing wells. It uses a continuous length of small-diameter steel pipe that is injected into the wellbore to drill or complete the well. CTD is a cost-effective and environmentally friendly alternative to conventional drilling methods, and it is becoming increasingly popular…
Pipeline transportation of heavy crude oil is a big deal within the global energy world, because it lets the transfer of high viscosity petroleum from production sites towards refineries, and also to export terminals. Now compared with light crude, heavy crude oil is usually denser, more sluggish, and it often carries more sulfur and a few other unwanted…
