The application of artificial intelligence (AI) has become inevitable in the petroleum industry.
In drilling and completion engineering, AI is regarded as a transformative technology that …

Wellbore trajectory design is a nonlinear and constrained mathematical optimization
problem that is used to build a cost-efficient, safe, and easily reachable trajectory. True …

The process of drilling a borehole is very complex, involving surface and downhole drilling
systems, which interact with the drilling fluid and the surrounding rocks. Modeling and …

Summary A “push-the-bit” rotary steering system (RSS) is one kind of advanced steering
technology widely used in the drilling of extended-reach wells and horizontal wells …

Directional well trajectory planning, which includes the optimization of the drilling site
location and the trajectory between the drilling site to the completion interval, plays an …

In the design of a shale-gas cluster horizontal well, it is necessary to consider the bypass of
the fracturing influence domains of existing wells and the interference between fracturing …

In shale gas mining, the inter-fracture interference effect will significantly occur if the actual
well deviates from the planned trajectory. To reduce production loss, operators want to get …

This paper serves to provide a technical overview of the Real-Time Drilling (RTD) analytics
system currently developed and deployed. It also serves to share practices used in …

In the horizontal drilling process, when the actual trajectory deviates from the planned
trajectory, it is necessary to take corrective action. The target point is difficult to determine …

Conventional directional well trajectory is designed to connect the wellhead and target point
or section with multiple engineering objectives including deflecting capacity, torsional …
