Multilateral wells are able to tap into the whole reservoir, as well as the surface area they occupy, which is very beneficial. However, the upside of the multilateral system translates into a downside quickly: well intervention and workover operations are, in terms of difficulty and risk, much more complex than in the case of common or single-lateral…
During the entire life cycle of an oil and gas well, Well Intervention (well repair/underground intervention operations) is a crucial step for restoring production capacity, extending well life, and addressing wellbore issues. However, this stage is also one of the scenarios with high incidence of non-productive time (NPT). As well conditions become more complex and operation…
In oilfields or geological research institutes, this phrase often marks the beginning of a journey of underground exploration. Well logging data, hailed as “the geologist’s eyes,” is the most crucial bridge connecting drilling engineering and reservoir understanding. One of the fundamental methods in the oil and gas industry is the interpretation of well logging data….
Shale oil drilling and conventional drilling are essentially different from each other in their technical and operational models, although both are aimed at crude oil production. These differences will be reflected in all stages of the project lifecycle, i.e., well design, cost structure, risk exposure, and workforce requirements. It is therefore vital for operators and service companies…
Coiled tubing operations are characterized by strict tolerances, constantly changing well conditions, and very little margin for error. With the increasing size, length, and complexity of wells, operational risks cannot be regarded as technical issues—they will influence safety, cost control, and project delivery in a direct manner. Using a coiled tubing simulator gives one the opportunity…
Operator training is an essential factor in the oil and gas industry when it comes to safety, production stability, and incident prevention. The more complicated the operating systems, the greater the need for training simulators with zero tolerance for errors—these are no longer optional tools but rather essential systems. On the other hand, the effectiveness…
With the continuous increase in the production of shale gas and shale oil, the drilling operations are more complicated in terms of engineering challenges than those in the case of conventional formations. The aforementioned difficulties arise due to the inherent characteristics of shale formations, i.e., low porosity, low permeability, high anisotropy, and giving with respect…
In the modern shipping environment, one of the biggest challenges faced by ships during navigation is the decision-making process in adverse sea conditions. Factors such as strong winds, large waves, complex ocean currents, and low visibility all combine to significantly increase the risks of misjudgment and accidents. Numerous maritime accident investigations have shown that human…
Training has always been one of the most important bases for safe, efficient drilling operations in the oil and gas industry. As drilling projects are getting highly sophisticated and the demands on safety keep going up, the pressure is on management to ensure that personnel understand processes, the behavior of equipment, and operational risks at…
In Navigation, port operations and navigation in complex waters, Navigation Errors have always been one of the important causes of ship collisions, stranding and yaw accidents. Although modern ships widely use advanced navigation devices such as GPS, ECDIS and radar, accident statistics show that technological progress has not completely eliminated navigation risks at both the…
