    Description

    SAFE, EFFICIENT CONTROL WITH REDUCED COST 

    Drilling high-pressure, high-temperature wells for oil and gas is often risky and complicated; temperature fluctuations combined with the pressures associated with deep hole drilling result in severe axial and tangential stresses at the borehole wall. Drilling mud is heated by a combination of pressure and mechanical friction and this heat can increase with the drilling action, altering the basic rheology of the drilling fluid. Hot drilling mud also affects the service life and accuracy of in-hole measuring devices that incorporate seal assemblies that can adversely react with high temperatures.

    The TUNDRA Offshore Mud Cooler provides effective control of drilling fluid temperatures considerably reducing the risks involved in such operations. It lowers operating costs by helping to extend elastomer service life and improves drilling mud condition while making it possible to decrease additives by stabilizing the rheological properties of the drilling fluid. Drilling efficiency is also increased by the use of mud coolers, resulting in greater endurance and accuracy for in-hole measuring devices and allows such tools to operate at greater depths. Health and injury risks to rig personnel are reduced by lowered drilling fluid temperature.

    TUNDRA Offshore Mud Cooler Design

    The TUNDRA Offshore Mud Cooler incorporates single or dual high-quality plate heat exchangers designed to ASME pressure vessel standards. These heat exchangers can be operated independently with a single parallel system or in series with a dual pack modular system with communal flow manifold.

    Plate heat exchanger technology (predominantly used in offshore applications) is used by running seawater and mud through adjacent plates that are connected and sealed to contain individually. Both fluids are controlled through a self contained mud/water manifold.
