Abstract: An apparatus, system, and method for the simultaneous remote control and monitoring of multiple wells. A main housing houses a plurality of hydraulic controls sets, each set of hydraulic controls corresponding to the fluid control valves of a well being controlled by the system. The controls are controlled by a programmable logic controller via solenoids. A control station housing houses a control station with separate touch screens for each well being controlled. The user can open and close the fluid control valves of each well using the corresponding touch screen. The touch screen also displays data for each well that is collected by a series of sensors throughout the well. The system can be pre-programmed with pre-approved valve sequences and/or safety alerts that are triggered based on the data collected by the sensors.

Abstract: A sand separation system for continuous sand disposal is disclosed. It includes a sand catching vessel to receive a multi-phase fluid stream (e.g., oil and gas production) containing settleable solids such as sand. A siphoning conduit connected to the vessel's lower end facilitates for continuous sand disposal. Continuous sand disposal is an operational improvement over conventional batch sand disposal systems. The separation system may feature a control valve on the siphon conduit to regulate sand flow and a water inlet to inject water into the sand collecting vessel. This continuous sand disposal design improves operational efficiency by avoiding separator downtime caused by batch removal of accumulated sand.
