GN Solids Control solids liquid separation decanter centrifuge have been working for oil drilling many years. The stable working performance and reliable life time win good reputation for GN Solids Control. And now we just published three phase  centrifuge for solids, water and oil three phase separation.

3-Phase-Decanter-Centrifuge

14-inch-decanter-centrifuge

Except for decanter centrifuge and three phase centrifuge, GN main market is still in drilling waste management and solids control equipment.

GN drilling waste management equipment including: vertical cuttings dryer, waste centrifuge, solidification unit, fixation unit, thermal desorption unit, etc. Drilling Waste management equipment is used to treat the solids mixture discharged from shaker, recover valuable drilling fluids for reuse and reduce the waste need to be treated in following stages.

For water based mud, client normal choose High G drying shaker, decanter centrifuge and solidification unit. After treatment of solidification unit, the solids can be buried in cement ponds as final step. For oil based mud, client need to use vertical cuttings dryer, decanter centrifuge, thermal desorption unit. Thermal desorption unit can get cuttings solids with oil below 0.3%, this standard can meet the requirement of most country’s government protection policy. Compared with water based mud, OBM cuttings treatment cost is much higher both in equipment expense and operation cost.

GN Solids Control equipment including: shale shaker, mud cleaner, shaker screens, desander, desilter, decanter centrifuges, mud agitator, centrifugal pump, screw pump, mud tanks etc. GN Solids Control mud system can form a close loop mud circulation with drilling rig and mud pumps. After the mud ready for drilling, the mud pump will suck from the mud system and feeding for drilling rig. The mud from drilling rig flowline will go back to mud tank system for cleaning, adjusting and go back to mud pump. The mud tank system generally include four stage mud treatment and will remove particles in different size by different stage, shale shaker stage, desander stage, desilter stage and decanter centrifuge stage. Two phase separation centrifuge is mostly used in solids control system, very few clients choose three phase centrifuge.

GN Solids Control is the first China drilling waste management equipment company who can offer total solution  equipment for drilling waste management Service Company.

2015.10.23 GN total solution for drilling waste management

Regarding Oil based mud drilling cuttings, the total solution of drilling waste management including below steps:

Step 1: Vertical cuttings dryer. Use this VG dryer to treat the drilling cuttings, recover the valuable oil based mud. The OOC after treatment can be 3%-5%.

Step 2: Thermal Desorption Unit. After VG dryer, the solids can go to TDU for non-hazardous final treatment. After TDU, the water, oil and solids can be separated in accepted degree which comply with most of country’s government policy on environmental protection

Step 3: Decanter Centrifuge. After VG dryer, the liquid part (drilling fluids) can go to centrifuge to remove the fine solids and go back to active mud tank for reuse. Some client let the liquid part discharged from VG dryer go back to active mud tank system directly. This is also OK.

Drilling waste management and zero discharge is a getting much popular recent years. It is important to get zero discharge on drilling waste management.  Many EPC company wanna source professional equipment and professional personnel on the potential projects with large profit.  The the drilling waste market capacity can reach 17 billion before 2018, it is said.

GN Solids Control is leading manufacturer for  drilling waste management equipment & solids control equipment; after some years experience accumulation, GN Solids Control can offer professional solution on drilling waste management and can answer the question most of the people faced with ” How to achieve zero discharge on drilling waste management “. This chapter will give a comprehensive knowledge of drilling waste (OBM & WBM) from three parts as below. And tell people how to achieve zero discharge on drilling waste management in Part 3.

  1.  Source of drilling waste
  2. Necessary drilling waste management equipment
  3. Treating process of drilling waste and How to achieve Zero discharge of drilling waste

Part 1: Source of drilling waste

Source 1: Drilling waste from oil based mud drilling operations. The assessment is yet to be conducted

Souce 2: Refinery waste: Most of it is waste water, sludge, and the usual refineries waste ingredients. The refinery waste will be first recovered from large ponds and for those ponds to be remediated to original status where we will plant them with trees.

Source 3: Storage tank sludge: The tanks are yet to be calculated in terms of number and storage capacity. However, they are estimated to exceed the 50 tanks mark.

Source 4: Oil pits (there are many oil pits and waste management service company are trying to do land remediation to original state which means they will treat the crude to get it back to its crude status, soil back to soil and water to be recovered):

Oil pit case from Iraq drilling waste management market:

  • There are over 120 oil pits to be treated.
  • More than 60% are emptied from crude and what is left is sludge and soil to be treated.
  • Average sizes are 100 miters in length, 70 miters in width and 5 miters in depth.
  • We will be dealing with all of them, the ones that have sludge and soil left and the ones that are still filled with crude.
  • The base of all pits is earthen. No concrete nothing else but earthen.
  • Our task is to treat all pits and remediate the land to original status where we will plant them with trees.
