Relative to the use of drilling fluids within the oil & gas/CBM industry, the use of drilling fluids within the horizontal directional drilling (“HDD”) & water well industry, is new. Until the 1980’s, drillers in HDD, water well drilling started to consider the use of basic drilling fluids. However，couple the evolution of drilling fluids with the escalating cost of waste management and disposal, the economic practicality of utilizing drilling fluids, is dependent on the ability to recover and recycle.
At before, there are a variety of methods to control solids to build up, such as natural sedimentation, simply discarding of the used drilling fluid, dilution of the drilling fluid with water etc. However, these methods have been proven to become uneconomical as the market expectations.
Today, the most effective method available for solids control is mechanical treatment---recycling system, which have become not only necessary, but financially advantageous.
When rig is more than 60T, packaged mud recycling system is an invaluable.
How to select proper recycling system to match our rig and mud pump?
Generally speaking, a mud system should be no smaller than 120% of the mud pump capacity, but no larger than 150% of the mud pump capacity.
