The MCS mud tank is capable of holding 1,000 gal. (3,785 L) of drill mud and can operate with a minimum of 200
gal. (757 L) of drill mud. A 3-in. (76 mm) drain plug is located at the rear of the holding tank under the shaker
discharge chute. A sand trap at the bottom of the tank collects sand from the drill mud.
The triplex mud pump is capable of operating at 450 gpm (1,703 Lpm) at 500 psi (3,447 kPa). The mud pump
hydraulics are powered by the MCS engine or the WWDR through the remote hydraulic connection. Discharge
and suction hoses are 20 feet (6 m), a sufficient length to run the MCS trailer from any location around the
WWDR.
MCS FEATURES
The MCS is mounted on a portable six-wheel trailer with a front drop-leg jack. The MCS trailer is equipped with
standard army hitching equipment in relation to the MCS weight, allowing the MCS to be towed by the WWDR.
The trailers axle vents were extended to allow the chassis to ford 20 in. (51 cm) of water at speeds of at least 5
mph (8 km/h).
The MCS contains a double screen shaker system, desanding cone system, mud pump, pickup pump, and Deutz
255-hp diesel engine.
The shaker system is capable of removing cuttings from drill mud through the use of shaker screens. The top
screen is a 4 ft x 5 ft (1 m x 2 m), standard hook-style 100-mesh screen. The bottom screen is a 4 ft x 5 ft
(1 m x 2 m), 10-mesh screen.
The mixing system contains a high-shear/low-pressure mixing hopper and also comes with a hydraulic-powered
centrifugal-to-pressure feed pump.
There are four manually-operated leveling jacks, two on each side of the MCS trailer, to stabilize the vehicle
without the risk of reduced capacity or failure.
The MCS catwalk system serves as a safety feature for personnel and runs the functional length of the MCS.
The MCS is equipped with tiedowns for rail, air, or ocean transport.
The MCS trailer is equipped with electric break-away system.
The MCS trailer has four LED flood/work lights to provide sufficient lighting to maintain drilling operations at night.
The flood/work lights are equipped with debris guards and are telescoping and perimeter-mounted near the center
between the front and rear of the trailer.
The mud pan is used to channel used mud from the drill hole to the sand guzzler. The mud pan serves as a
reservoir through which the mud pump draws the used mud and cuttings before they are passed through hoses to
the MCS.
The engine is a Deutz, water-cooled, 255-hp diesel engine. The engine operates on JP-8 or DF-2 diesel fuel and
is supplied by a 35 gallon (132 L) fuel tank. The engine is clearly labeled JP-8/DF-2 Diesel in 1-in. (25 mm) high
letters.
The sand guzzler pickup pump is a completely submersible, hydraulically-powered pump, capable of operating at
up to 2,900 rpm. Four hoses connect the pickup pump to the MCS. Two of the hoses are used for hydraulic
pressure, one serves as the hydraulic case drain, and the fourth hose is used to discharge mud back to the MCS
tank.
PAC CAPABILITIES
The PAC is capable of enhancing the WWDR on-board air compressor by adding an additional 1,170 cfm/350 psi
(33 cmm/2,413 kPa) to the drill rod string, lifting drill cuttings to the bore hole surface, and/or assisting in
developing the water well when the drilling is completed.
The IR-HR2.5 compressor is an oil-flooded, rotary, screw-type air compressor capable of providing 1,170 cfm/350
psi (33 cmm/2,413 kPa) and the required cfm (cmm) needed to reach Total Depth (TD) when tied into the WWDR
compressor.
