In oil and gas drilling operations, well control has always been the core aspect of safety management. Although the well control theory, operation norms, and equipment system are already quite mature, from the global accident statistics and review results, major accidents such as well surges and well blowouts still occur repeatedly. A common issue that…
Human mistake remains the top factor that leads to incidents, production losses, and unplanned downtime in oil and gas operations, together with other contributors, among them technical failures. Even though automation and control systems have greatly developed, human critical thinking is still the main factor in daily operational performance, mostly under time pressure and complex…
In the oil and gas production system, pipeline transportation is a crucial link that connects upstream production with downstream processing, storage, transportation, and end-users. Compared to drilling and well completion operations, pipeline transportation often has longer operation cycles and a wider coverage area. In case of an accident, the impact lasts longer and the economic…
As the oil and gas industry increasingly demands safety, efficiency and standardization, traditional training methods (classroom lectures, video demonstrations, on-site shadowing) have become increasingly unable to meet the actual operational needs in high-risk and complex situations. Against this backdrop, VR (virtual reality) training is becoming an important tool for oil and gas enterprises to enhance personnel…
Cost reduction has now become a pressing urgency in the shale gas drilling industry, driven by volatile gas prices, increased capital discipline, and rising operational complexities. But it is not only for digital technology today. It is primarily for integrating technologies with drilling workflows. Achievable goals for cost reduction while drilling shale through the reduction of drilling…
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…
