...Causative factors of blowout accidents in H₂S oil and gas wells Abstract Blowout is one of the most serious accidents in the drilling process of hydrogen sulfide (H 2 S) oil and gas wells, often accompanied by the leakage of H 2 S and other toxic gases, which easily causes...

... is beginning to explore extreme environments, where oil and gas reserves are plentiful, but in regions so inhospitable that humans cannot conduct and operate the drilling process on-site. A solution to this is to make use of autonomous robotic drilling systems. The use of robotics in any industry presents...

... How can technology help us? Is it time to look at the drilling process itself and the way we manage it? Are we using real-time drilling process data when it has its highest value? The rest of the paper will explore the possibilities for step change improvements in the way we control the drilling...

... in the reservoir. However, even on these high-tech wells the drilling process itself is still controlled mainly using traditional surface acquired data such as hook load, ROP, RPM etc. The transmission and utilization of downhole drilling process data in addition to the surface logging data offer a not yet fully...
