A method and apparatus for managing separation between vehicles. A closest point of approach between a first vehicle traveling along a first path and a second vehicle traveling along a second path is predicted. A number of compensation commands for altering the first path of the first vehicle are generated using the closest point of approach and a desired level of separation between the first vehicle and the second vehicle. The number of compensation commands is integrated with a number of control commands for the first vehicle to form a final number of control commands configured to maneuver the first vehicle to substantially maintain the desired level of separation between the first vehicle and the second vehicle. A response of the first vehicle to the final number of control commands is a desired response.

An automated closed loop flowback and separation system that allows automated control and remote operation of a flowback operation from a safe distance without any fluid or gas release to the atmosphere. Four-phase separation tanks allow the transport gas, well bore cuttings, produced oil, and produced water to be automatically separated and transported through process piping for reuse or sale, eliminating the need for auxiliary equipment. Flow measurement instruments, pressure transmitters, and level transmitters work in conjunction with an automated blast choke to send data to a programmable logic controller for use in calculating the erosion status of the choke restriction and adjusting the choke to compensate. The programmable logic controller works with a touch-screen or similar human-machine interface to allow remote monitoring and control or automated control of the system. The automated blast choke can vary the choke restriction opening based on the pressure differential and flow rate conditions.

A fluid separation system is provided for separating wellbore fluids into production fluids and non-production fluids. The system includes a separator adapted for transmitting mechanical power between a drive motor and at least one pump. The separator includes one or more separation units, such as hydrocyclone separators. A drive train traversing the separator is interfaced with drive elements, such as a submergible electric motor, and driven elements such as an injection or production pump. Wellbore fluids are channeled through the separator in either a push-through or pull-through manner. Production fluids are then transferred from the separator to the production pump for removal from the well. Non-production fluids are transmitted from the separator either to the injection pump for reinjection into a subterranean discharge zone, or directly into the discharge zone from the separator. The drive train elements traversing the separator are supported by antifriction bearings in interface plates on either end of the separator. The ability to transmit mechanical power through the separator facilitates assembly of pumping system components in various configurations as well as piping fluid communication paths between the pumping system components.

Permeable polymeric monolithic materials are prepared in a column casing. In one embodiment, the permeable polymeric monolithic materials are polymerized while pressure is applied through a piston having a smooth piston head in contact with the polymerization mixture. The pressure eliminates wall effect and changes the structure in the column. Similarly, some columns that have a tendency to swell in the presence of aqueous solutions and pressurized while the solution is applied to prevent swelling and wall effect. This procedure also changes the structure in the column. The size of the separation effective openings can be controlled by the amount of the pressure and pores eliminated. Uniformity in the direction flow is improved by controlling polymerization with radiation rather than with conducted heat.
