Workover Operations

The Well Services BOP provides independent pressure control over the well. The well services BOP is a specific item of equipment installed when the client wishes to focus on well service operations without using any of the standard rig equipment, viz. a viz. the rig BOPs. It is usually combined with the auxiliary-pumping console.

The Auxiliary Pumping Panel represents a pumping unit specifically for Workover operations. The console can control two duplex or triplex pumps and these are configured via the Instructor Station. The console allows simultaneous operations of the drilling simulator and the Workover simulator.

The full size Wellhead and Christmas Tree is manufactured in Steel and provides a physical representation of a 20" casing Head Housing, 13-5/8" casing spool, 9-5/8" casing spool and Tubing spool. All spools have two outlets. The tubing spool offering connection to the "A" annulus has two isolating wing valves. The Tubing Spool is bolted to a McEvoy style Y-block Christmas Tree with Master, Swab and two wing valves. A Dual Completion Wellhead is also available.

The full size Surface Operations Choke Manifold is provided in a land or deck style. This offers a variation from the Rig Manifolds which, are provided in vertical arrangement. The Workover manifold provides a connection from the rig pump (and/or optional auxiliary pumps) to the annulus and tubing. This allows both forward and reverse circulation. Downstream of the three chokes are connections to the Mud Gas Separator and the flare. Fluid returns going to the Mud Gas Separator are returned to the active system where returns directed to the flare are lost.

Where classroom space is limited and full size equipment could not be installed, or where budgets are limited, the Workover Mimic Panel is suitable. The design is based around a 1m x 1m mimic panel fascia mounted onto a 1.8m high stand with a screen-print fascia of the Workover manifold, Wellhead and Christmas Tree.
