The drilling fluids with the cuttings from the well are discharged to a rig shale shaker where the cuttings are separated from the drilling fluid. The separation step does not completely remove drilling fluid from the cuttings, some drilling fluid and additives remain on the drill cuttings.

Then such drilling cuttings with drilling fluids will be dropped into a GN drilling waste system, through physical way to separate the usable drilling fluids with unusable drilling cuttings. For example, hi-G shale shaker to separate larger drilling cuttings, then verti-cutting dryer to separate drilling cuttings with oil less than 5%.The usable drilling fluids are treated by decanter centrifuge, then clean drilling fluids and water will back to rig again.

The cuttings separated by verti-cutting dryer with less than 5% oil can not be drain off directly, it may pollute the environment. We must use chemical way to continue the treatment.

Drilling cuttings treatment method:

Thermal desorption, re-injection, incineration and solidification.These methods have been applied in the site, they may have their own advantages and disadvantages.

Thermal desorption:

use of the patented Porcupine Processor to remove all water and oil, leaving a residual total petroleum hydrocarbon on cuttings of less than 1%.

Re-injection :

GN solids control is in a process of design and manufacture vertical cutting dryer, we will get it into production in several months.

drilling cutting management

drilling cutting management

The first step in managing drilling wastes is to separate the solid cuttings from the liquid drilling mud. Once solid and liquid drilling wastes have been separated, companies can use a variety of technologies and practices to manage the wastes. For some applications, drilling wastes are solidified or stabilized prior to their ultimate management practice. The management technologies and practices can be grouped into three major categories: waste minimization, recycle/reuse, and disposal.

GN solids control equipments can make the first step of solids control, to clean the drilling mud and reuse for drilling rig.

If the solids collected by the shale shakers are still coated with so much mud that they are unsuitable for the next reuse or disposal step or if the used mud is valuable enough to collect as much of it as possible, the solids can be further treated with drying shakers utilizing high gravitational separation, vertical or horizontal rotary cuttings dryers, screw-type squeeze presses, or centrifuges. The cuttings dryers recover additional mud and produce dry, powdery cuttings.

Our equipments can do a series job for drilling cuttings management, firstly we use high G shaker to dry the drilling cuttings and recycle a small part of the drilling fluids for re-use. Most of the drilling cuttings are dried and transferred to vertical cutting dryer by screw conveyor. The dry the drilling cutting is, the better performance can reach by the cutting dryer.

After processed by vertical cutting dryer, the large solids are separated out, and sent to Cement Plant or brickyard or used for construction industry. The separated fluids are pumped by screw pump to a high speed centrifuge for further process. Finally the clean mud can be re-used for drilling rig or re-used to make new mud.

Following is the ways can reuse the drilling waste.

We are looking for Drilling Cuttings Screw Conveyors partner,since we are solids control system manufacturer.When designing a total mud system,we need to integrate drilling cuttings screw conveyors.

  1. Drilling Cuttings Screw Conveyors (Augers)

1 x ±24ft screw type cutting conveyor fitted with independent electrical motor and with sensor capable to stop the engine if any alien body is engaged into the screw.

Conveyor should be calculated to absorb overflow of cuttings when drilling 26” or 17” hole (1000gpm flow rate).

1 x ±36ft screw type cutting conveyor as above.Which are used before the drilling mud shale shakers.

We only work with manufacturer for drilling type cuttings converor,if you are interested,please send your info. to info@gnsolidscontrol.com.
