Drilling system and method

TL;DR: In this paper, a system and method for controlling formation pressures during drilling of a subterranean formation utilizing a selectively fluid backpressure system in which fluid is pumped down the drilling fluid return system in response to detected borehole pressures.

TL;DR: In this article, an expandable tubular sleeve having utility for lining a downhole tubular member includes a tubular body having a portion that is predisposed to initiate expansion thereof under the application of internal fluid pressure.

TL;DR: In this paper, a method and apparatus for detecting a kick in a wellbore using acoustic transducers is presented, which includes an acoustic transducer and kick detection circuitry coupled to the acoustic transceiver.

TL;DR: In this paper, a method and apparatus for orchestrating multiple fractures at multiple well locations in a region by flowing well treatment fluid from a centralized well-treatment fluid center is disclosed that includes the steps of configuring a well treatment fluids center for fracturing multiple wells, inducing a fracture at a first well location, measuring effects of stress fields from the first fracture, determining a time delay based in part upon the measured stress effects, inducing another fracture after the time delay at a second location based on the measured effects, and measuring the stress effects from the second fracture.

TL;DR: In this article, an automated method and system for recognizing a well control event including determining a state of drilling operations is presented. But this method is limited to a single well and cannot be used for all of the well control events.

TL;DR: In this paper, a system and method for controlling formation pressures during drilling of a subterranean formation utilizing a selectively fluid backpressure system in which fluid is pumped down the drilling fluid return system in response to detected borehole pressures.

TL;DR: In this paper, the authors present a process control optimization system for oilfield hydrocarbon production using intelligent software objects which exhibit automatic adaptive optimization behavior, which can be used to automatically manage hydrocarbons production in accordance with one or more production management goals.

TL;DR: In this article, a system for drilling a subsea well (30) from a rig (20) through a sub-sea wellhead below the rig(20) includes a wellhead stack (37) which is mounted on the subsea surface wellhead.
