Abstract: An apparatus and method for communicatively connecting a control workstation with wellsite equipment. The apparatus may include a data communication hub communicatively connected with fluid control equipment of a well construction system for constructing a well at an oil/gas wellsite, and a control workstation communicatively connected with tubular handling and rotation equipment of the well construction system. The control workstation may be communicatively connected with the data communication hub and with the fluid control equipment via the data communication hub.

Abstract: This disclosure is generally drawn to systems, devices, apparatus, and/or methods related to choke systems for drilling environments. Specifically, the disclosed systems, devices, apparatus, and/or methods relate to choke calibration, position, and time display systems for drilling environments. In some examples, a choke display for providing choke status, position, time, and/or calibration information is provided, in some examples, an apparatus may include a circuit board having a right side and a left side, a first set of sensors disposed adjacent the right side of the circuit board, a second set of sensors disposed adjacent the left side of the circuit board, and a display portion configured to display a first mode and/or a second mode based on an actuation of the first set of sensors and an actuation of the second set of sensors.

Abstract: A vibrating screen separator. The vibrating screen separator may be operated in a linear, an elliptical, or in a transition from elliptical to linear modes of operation. In the linear mode of operation, the screen separator moves along a reciprocating straight line path, and, in the elliptical mode of operation, the screen separator moves along an elliptical path. In the transitionary mode of operation, the screen separator is transitioned from movement along the elliptical path to movement along the linear path.

Abstract: A borehole includes a tubular member, a sealing member for sealing an annulus between the tubular member and the borehole, a pump for pumping fluidic materials into the tubular member, and an automatic choke for controllably releasing pressurized fluidic materials out of the annulus. A system and method monitor the operating pressure within the tubular member and compare the actual operating pressure with a desired operating pressure. The difference between the actual and desired operating pressure is then processed to control the operation of the automatic choke to thereby controllably bleed pressurized fluidic materials out of the annulus thereby creating back pressure within the borehole.
