The oil and gas industry depends on different types of drilling rigs to access underground hydrocarbon resources. Among the most important categories, you will find land rigs and offshore rigs. Even if both do the same main job, meaning drilling wells for oil and natural gas production, they still diverge pretty clearly in their operating environments, design,…
Drilling fluid pressure management is one of the most important things that really affects drilling performance, wellbore stability, and operational safety, during oil and gas work. People usually talk about two major drilling approaches for controlling formation pressure. One is underbalanced drilling(UBD). The other is overbalanced drilling(OBD). The key difference between them is the relationship…
In the oil and gas industry, well workover refers to the maintenance, repair or remedial operations carried out on existing oil and gas wells to restore, maintain or enhance production, and ensure the integrity of the wellbore. Well workover operations may involve repairing or replacing downhole equipment, cleaning the wellbore, modifying the well completion, increasing production, and…
Oilfield operations involve complex equipment, hazardous materials, high-pressure systems and some really tough job sites. From drilling sites and production facilities to offshore platforms, unexpected emergencies can pop up any time. The right emergency response training, helps oilfield people know the knowledge, skills, and that calm confidence they need to handle incidents fast, lower risks,…
Offshore platforms are among the most advanced engineering structures used in the energy industry; They are built out in oceans and seas across the globe, and these facilities act as a working base for exploring, drilling, producing and processing oil and natural gas resources that sit underneath the seabed. Compared with onshore sites, offshore platforms…
The training for underground logging personnel is not merely about teaching them how to use logging tools; it also requires them to master the logging principles, operate the equipment in accordance with the norms, accurately interpret the data, and be able to make correct judgments in emergencies. For oil and gas companies, these capabilities cannot…
Drilling safety has always been one of the top priorities in the petroleum industry. Even when we’re talking about oil and gas exploration, mining, or geothermal drilling, workers deal with a lot of hazards, like high-pressure gear, heavy machinery, toxic vapors, and other risks. Traditional drilling work often leans strongly on manual watching and decision-making;…
Oil recovery from reservoirs is a complex process influenced by various factors. Generally, only a portion of the total oil present in a reservoir can be extracted using primary recovery methods, typically ranging from 5% to 30%. This leaves a significant amount of oil untapped. However, through the application of advanced techniques such as Enhanced…
Drilling technology has kept evolving to push operational efficiency, safety, and wellbore quality forward. In rotary drilling operations, two main drilling drive systems show up over and over, the Top Drive system and the Kelly Drive system. While Kelly Drive tech has been around for decades and it still works well in many jobs, Top…
Deepwater drilling operations at depths exceeding 3000 meters are regarded as one of the most challenging and colossal projects in the oil and gas industry. Conducted under extremely high static water pressure at the seabed and near-freezing seawater temperatures, there can be no room for any human error. And the core defense line to ensure the…
