Increasing the global demand for natural resources directs the oil industries to explore in
geologically challenging structures and offshore reserves. Oil industries are always …

Downhole abnormal incidents during oil and gas drilling cause costly delays, and may also
potentially lead to dangerous scenarios. Different incidents will cause changes to different …

Mode confusion is an automated system behaving differently than expected and the
operator not being aware of (or not properly understanding) what the system is doing. Mode …

In oil and gas drilling, corrosion or tensile stress can give small holes in the drillstring, which
can cause leakage and prevent sufficient flow of drilling fluid. If such washout remains …

Early diagnosis of incidents that could delay or endanger a drilling operation for oil or gas is
essential to limit field development costs. Warnings about downhole incidents should come …

Detection of early signs of stuck pipe incidents is crucial because of the enormous costs of
recovering from the incidents. Previous studies have leaned significantly toward a physics …

Stuck pipe events continue to be a major cause of non-productive time (NPT) in well
construction operations. Considerable efforts have been made in the past to construct …

Managed pressure drilling (MPD) has a promising prospect in complicated formation where
drilling faults always happen. Automatical drilling fault classification is one of the key issues …

We describe the validation of a software solution that automatically detects changes in
downhole drilling conditions. Based on early warnings provided by the system, the drilling …

Automation consists of the use of control systems to control processes, reducing the need for
human intervention. There has been considerable progress made in automating key tasks …
