Abstract: System and method for controlling drilling rig operations where a control system coupled to a drilling rig obtains performance information during drilling of a well. Using the performance information obtained during drilling of the well, historical data regarding performance information relating to wells previously drilled, and a well plan, the control system can predict the time required to complete drilling of one or more subsequent portions of the well and the cost associated with the time. The control system can compare the cost associated with the time to a target value. If the difference between the cost associated with the time and the target value exceeds a threshold, then the control system can generate an updated drilling path and control information can be sent to drill the well according to said updated drilling path.

Abstract: An apparatus for obtaining fluids via a well includes an outer tubing disposed in the well and set at a shallow reservoir comprising a first fluid, and an inner tubing disposed concentrically within the outer tubing and set at a deeper reservoir further downhole than the shallow reservoir. The deeper reservoir has a second fluid, where a first packer is disposed between the outer tubing and an external tubing and disposed above the shallow reservoir, and a second packer is disposed between the outer tubing and the inner tubing and disposed above the deeper reservoir. The second packer blocks an annulus through which the first fluid is extracted via the outer tubing. The first fluid is obtained from the shallow reservoir and the second fluid is obtained from the deeper reservoir by drilling via the well.

Abstract: A method for optimizing a wireless sensor network for monitoring hydrogen production from fire flooding involves training a machine learning model to generate an estimate of communication performance of each of a multitude of sensors. The sensors are a component of the wireless sensor network disposed in a sub-surface hydrogen reservoir, with each of the multitude of sensors configured to obtain measurements of environmental variables of the hydrogen reservoir. The method further involves minimizing a cardinality of the multitude of sensors, using the machine learning model.
