In nowadays, a complete oil and gas drilling rig should be equipped at least 2 mud systems: One called solids control system for drilling fluids treatment; another system called the pitless mud system for drill cuttings treatment.
Many clients are wondering, if the pitless mud system for drill cuttings system can replace the shaker tank system or not?
Firstly, we have a draft idea about the 2 mud systems.
Solids Control system for drilling fluids treatment
Complete solids control system can be composed of 4-stage solids control equipment or 5 stage solids control separation process.
The 1rst stage solids control equipment: shale shaker. It is used to remove the coarse particles from the drilling fluids.
The 2nd stage solids control equipment: Desander, it utilizes 10’’ hydrocyclone cones to remove particles above 47 microns.
The 3rd stage solids control equipment: Desilter, it utilizes 4’’ hydrocyclone cones to remove particles above 27 microns.
The 4th stage solids separation equipment: Decanter centrifuge. It utilizes centrifugal force to remove the fine solids to 2 ~ 5 micron. Middle speed decanter centrifuge is normally used this stage to recovery the barite.
The 4 stages solids control equipment composed of 4 stage separation. Another separation is for vacuum degasser. It is used after shale shaker and before desander desilter.
Clients chose the suitable separation machine per rig condition.
As the mud pit is forbidden in China at the rig site, pitless mud system for drill cuttings treatment are more and more equiped.
1) High G drying shaker, it is normally used to treat water base drill cuttings.
2) Vertical cuttings dryer. It is used to treat oil base drill cuttings.
3) High speed decanter centrifuge will be used after high G drying shaker or vertical cuttings dryer to separate the fine solids
4) Dewatering unit. If there are many ultra fine solids cannot be removed by centrifuge directly. Dewatering unit for chemical dosing will be used.

GN Solids Control (with a separate US brand and company, GN Solids America) is a leading manufacturer for drilling waste treatment system. GN brand drilling waste management equipment and system are sold to over 60 countries and regions worldwide, including USA, Canada, Argentina, Brazil, Chill, Egypt, Algeria, Libya, Saudi Arabic, Iran, Iraq, Nigeria, Turkey, India, Indonesia, etc…
GN drilling waste treatment system are suitable to treat the drilling cuttings with rigs or in the waste mud pit.
Below is a general idea of the treatment for oily waste from drilling rigs or from oil refine industry.
Step 1: Oily sludge mixing tank, 1 ea
The oil waste from mud pit goes to the tank and it is mixed with chemicals. There is mud agitators equipped to the tank to stirring the oil waste with chemicals. The chemical is used to make the oil comes out from the waste. The oil, waste and solids are easy to layering after settle down. Solids from the tank goes to shaker for treatment.Liquid goes to oil water separator.
Step 2: High G drying shale shaker 1 ea and Decanter centrifuge 1 ea. This step is for mechanical separation.
A 4-panel high G drying shaker is used in this step. The shaker is used to remove coarse particles from the oil waste. The liquid will be further separated by the 1# decanter centrifuge. Solids phase from shale shaker goes to TDU for further dry. Liquid phase from 1# decanter centrifuge goes to dewatering unit and then separated by high speed centrifuge.
Step 3: Dewatering unit and a high speed Decanter centrifuge 2# for remove the fine solids
Flocculants from dewatering unit is mixed with the liquid from 1# decanter centrifuge. And then the mixture of chemical and liquid goes to centrifuge 2# for treatment. Solids from 2# decanter centrifuge goes to TDU. The Fluids from 2# centrifuge is mixture of oil, water and small content of ultra fine solids, they can go to oil water separator.
