Oil drilling rig welded pipe life has been estimated by simple integration of the Paris law, as well as by more complex simulation of fatigue crack growth, using the extended Finite Element Method (xFEM). Probability of failure is then taken as the ratio of the number of cycles for a ...
It depends on separating the variation in data into components (Sktani et al., 2018). The coefficient of determination (R2), the adjusted coefficient of determination (Adj. R2), the predicted coefficient of determination (Predicted R2), and the adequate precision, are used to describe the ...
Orientation: A professional One-stop supplier of oil and gas drilling equipment. Mission: To provide high quality products and services for the oil and energy industry. Values: Take responsibility and work hard,with seizing the day Vision: To serve more than 80% of oi...
As a fleet of machines in the considered company covers more than 1000 loaders/trucks/drilling machines, the importance of this approach is serious from a practical point of view. We believe that it could be also an inspiration for other researchers working with industrial data. Keywords: ...
Understanding Crude Oil Crude oil is typically obtained through drilling, where it is usually found alongside other resources, such as natural gas (which is lighter and therefore sits above the crude oil) and saline water (which is denser and sinks below). After its extraction, crude oil is ...
1.Modular and virtual manufacturing technologies are adopted in design, so that the structure of products is optimized and components are highly standardized, generalized and seriated. 2.Key structural elements are subject to finite element analysis to ensure stable performance and hi...
The exploitation of casing steel pipes used in oil and gas drilling rigs typically involves a corrosive atmosphere, high pressures and elevated...
Stainless steel pipe is a kind of hollow long round steel, which is widely used in industrial transmission pipelines such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instruments and mechanical structural components. ...
The steel materials of PDC Drill Bit is AISI 4145H alloy structural steel . AISI 4145H alloy structural steel: This is a steel specifically used for oil drilling tools, especially for the manufacture of heavy-duty drill pipes. AISI 4145H steel has good wear resistance...
Of the possible mechanisms responsible for casing collapse, the disturbance in local field stress around a wellbore, usually initiated during the drilling process is the most common cause. Subsurface rock formations often do not exist in conditions that are static and stable over long periods of ...
