There are several different types of drilling muds used for different drilling conditions, mainly divided into 3 types, the water based mud, oil based mud and SBM. The mostly used ones are WBM and OBM.

For deep well drillings, the OBM is most common solution. Considering it’s components, the oil based mud is more expensive than water based mud, that’s why as much as mud should be recovered from the waste. Meanwhile, the OBM is more harmful to the environment if the cuttings from drillings are not well treated before discharge. As leading manufacturer and solution provider, GN Solids Control has designed and supplied to many different end users with its professional solution for drilling cuttings treatment. For oil base mud cuttings, recently, another new set of such system was successfully use in CNPC, one of the 3 largest oil companies in China, both their engineers and operators are giving good comments.

cuttings treatment system

This system includes:

1. GNCD930 vertical cuttings dryer, which is specially designed for treating the oil based cuttings, it is like a washing machine. By using screen baskets of different mesh sizes per cuttings condition, and after the vertical cuttings dryer, the oil on cutting could be reduced to below 0.5%.

2. The second treating machine is a high speed decanter centrifuge. In this project, the end user chose GNLW363CG-VFD, a 14 inch diameter bowl decanter centrifuge, with variable speed up to 3200RPM. It is used for further treatment of drilling fluid discharged from the vertical cuttings dryer.

3. Transferring equipment. For transferring the drilling cuttings, GN has different suggestions based on customers’ jobsite layout and cuttings location. Normally, if the cuttings treatment system is alongside the rig and used for treating the cuttings direct from solids control system, screw conveyor is good choice to collect cuttings from shaker and transfer to hopper of vertical cuttings dryer. If the wed cuttings are from a pit or pond, we recommend GNSP vacuum pump.
