OBM Drilling Waste Management Total Solution
2016-01-13 11:37:54

Oil based mud poisonousness is mostly decided by the arene in the diesel. The higher content percentage of arene in diesel, the more serious of the poisonousness. To reduce the poisonousness of the OBM to environment, non-poisonous OBM is under research, but the cost of the new technology base oil is very high. Most of the drilling company will choose the traditional method to treat the OBM drilling waste.

GN Solids Control is professional equipment & solution provider of OBM drilling waste management. In the past 3 years, we have over 20 sets drilling waste management working in domestic market and overseas market. As per feedback from client, the working performance is much accepted, the poisonous drilling waste turned into recycling material without environmental pollution.

GN OBM drilling waste management total solution including below items:

1) Vertical cuttings dryer

The vertical cuttings dryer will treat the drilling waste discharged from shale shaker via screw conveyor transportation.

After treated by vertical cuttings dryer, the solids discharged from vertical dryer will be move to solidification unit / thermal desorption unit for final treatment.

After treated by vertical cuttings dryer, the liquid discharged from vertical dryer will be lead to centrifuge to separate the fine solids, lower down the mud weight.

2) Waste management decanter centrifuge

The liquid mud discharged from vertical cuttings dryer will be sent to centrifuge via mud transfer unit with mud agitator.

After treated by centrifuge, the solids discharged from centrifuge will be move to solidification unit / thermal desorption unit for final treatment.

After treated by centrifuge, the liquids mud discharged from centrifuge will flow back to mud tank system for reuse for drilling.

3) Solidification unit

Solidification unit is used to mix the mud solids waste with agent ( like cement, lime etc.) to fix the mud stay in a form of stable, no leakage, no flow ability, no harmful to surrounding environment. It can be used for OBM drilling waste and also WBM drilling waste if the client no needs to recycle the base oil.

4) Thermal Desorption unit Thermal desorption unit is replacement for solidification unit. The client can choose one for different target. TDU can recycle the base oil for sell, or reuse for drilling base mud. Compared with Solidification unit, TDU operation cost is much higher.
