In February 2019, GN Solids Control began the manufacturing of its first automatic mud tank cleaning system for a customer in America, a significant moment for China manufacturer of solids control equipment in oil and gas drilling.

Mud tanks cleaning has been a tedious and labor intensive work. Whenever a drilling rig changes to a new kind of mud, or there is too much deposition of expensive barite on the bottom of mud tank, cleaning work has to be performed. Workers with heavy equipment need to come into the refined space of a mud tank to clean mud residuals with high pressure chemical solution spray, exposing themselves to the dangerous environment.

GN Solids Control’s automatic tank cleaning system can bring this high risky high cost work to an end.

Using its mature sub systems, GN Solids Control’s automatic tank cleaning system can automatically finish mud tank cleaning work.

Chemical solution is prepared in the dosing tank with dosing pump. An automatic mixer will add chemical solution automatically to the buffer tank.

Buffer tank provides chemical solutions to booster pump, which pressurizes the solution and send it to automatic tank cleaner.

Automatic tank cleaner scans the inside of mud tank at preset scanning patter, hitting each and every spot of mud tank inner shell to kick out mud contaminant. It takes about 15 minutes to finish a complete scanning cycle.

A powerful suction pump will collect dirty solution, including deposited barite, from the bottom of mud tank, and transfer it to clarifier.

Specially designed clarifier set the solids in the liquid very quickly. While solids accumulated at the special shaped bottom of clarifier being pumped out by a membrane pump, clear solution on top of the clarifier will overflow to the buffer tank, being ready for the next cleaning cycle.

Automatic tank cleaning system by GN Solids Control features:

  • High efficiency. A mud tank can be cleaned in a matte of hours
  • Fully automatic: no operator interference is necessary
  • Much less risky: human entrance into dangerous environment is minimized;
  • Much less costly: only one operator is needed and human cost is cut tremendously.

In the oil and gas drilling, mud tanks need regular cleaning for many reasons. Some of them are:

  1. Using the mud tank for mud of different properties
  2. Making the mud tank ready for new drilling tasks
  3. Getting rid of the deposit on tank bottom
  4. Maintaining the effective volume of mud tanks
  5. Increasing tank efficiency

Most of the tank cleaning job is done manually. Workers needs to get into the restricted space to clean the mud tank using high pressure spray. This is a tedious and dangerous process as the workers have very limited movement in a limited space, where temperature is usually extreme, no air circulation, existence of dangerous gas (inflammable, explosive, corrosive, etc.), exposing the worker to a very dangerous and labor demanding environment, a big challenge to HSE regulation practioners.

Automatic tank cleaning systems will effectively eliminate the problems for such job.

In general such system will have a cleaning machine positions in the mud tank, which connects with high pressure chemical solutions dosed for the particular cleaning job (usually surfactant). The cleaning machine will spray high pressure solution in a special cleaning pattern, so that the mud tanks can be cleaned properly.

Centrifugal pumps will send pressurized chemical solution to the cleaning machine located in the mud tank. The cleaning machine will apply high pressurized solution to the tank surface to “rush” mud residual out. Vacuum pump transfers the sludge to the post processing equipment such as desilter, and inclined plate clarifier, to separate the solids. The solutions will be transferred back to buffer tank and be reused, forming a closed loop cleaning system.

The advantages of such system are:

  1. Greatly increase cleaning efficiency, usually four hour is required to clean one tank around 6,000m3
  2. Usually a 30-40% reduction of confined entry to mud tank;
  3. And 1/3 less of waste solids generated

GN Solids Control manufactures GNTC-30B closed loop automatic cleaning system. In addition to the above features, this system also carries the following advantages:

  • The whole system is integrated into a compact package, with everything included in it;
  • Mature: major sub-systems such as inclined plate clarifier, centrifugal pumps, vacuum pumps are from GN Solids Control, demonstrating reliable outstanding performance;
  • Flexible: this system can be configured with many other features. It can be customized with the addition of agitator for the addition of chemical to accommodate needs for the cleaning of different muds (water based, oil based, etc.), heating systems for the extreme weather conditions, and so on;
  • The complete package can be loaded on a truck (temporary or permanently) to perform mud cleaning jobs in different locations, which can greatly improve the profitability of the service provider using such system;
  • Automation options available. Automation packages can be added to the system to achieve advanced cleaning capabilities including closed loop pressure control, customized recipes for different tank sizes and shapes, and a more precisely defined scanning & cleaning pattern.

Recycle the drilling mud that lubricate the drilling bits.

The drilling mud solids control system is for filter away danger solids phase that contain in the drilling mud and reuse the needed solid phase.  The task is to keep drilling fluids in stable performance status.  There are several machinery that will need to perform the tasks.

The result of consist performance of drilling mud is avoid the blocking and damage of the oil and gas channel. It reduce the well drilling torque and friction drag and reduce the pressure oscillation of the annular air suction.  It also increase the velocity of the well drilling, extend life of the drill bit, reduce wear of the equipment.

drilling mud system

There are  five steps of filtering process that require five solids control machinery that will do  filter screening, degassing the mud, desanding the mud, desilting the mud, centrifuge force separation and demand of weighting up mud. The consist work flow between every solids control equipment use in the whole system is very important.   Level one to five level of output of the mud should be matched each other and the interval of separation size should be appropriate and have a certain overlap.  The result of the smaller solids which are not filter by the upper can be filter in the next controlled level.

With the development of well drilling technology, mud mixing system plays an important role in drilling operation. The various kinds of solids control systems function at the same time. Regardless the different kind of the solids control system, it’s basic function will not changed. It is depend on organic combination of mechanical removal equipments, drilling fluid mud tanks and other auxiliary equipments to accomplish the basic function:  Recycle the drilling mud that lubricate the drilling bits

Not long ago, GN solids control finished the manufacture for several units de-sanding product used for bored piling job. These de-sanding units usually are separately for the customer received from Saudi Arabia, Singapore, Myanmar and a China domestic client. Besides the bored piling assignments, this small footprint along with cost effective machine can also be traditionally used in TBM and HARD DISK DRIVE projects.

GN’s de-sanding device is a composition unit such as the primary shale shaker and cyclone unit with 2 development solids separation function. The significant principle of GN De-sanding unit is as follow:
1 ) A Pit pump will certainly suck the drilling body fluids from the mud pit and also transfer to the de-sanding product shale shaker for coarse hues separation. Please note that the opening pump is an extra system which the customer can choose to have from GN solids conrol or obtain locally.
2 . The liquefied goes through the mesh display screen of 20/40 mesh will probably temporally stored in the below located mud catching fish tank waiting to be transferred to often the cyclone unit for further separating.
3. The self-contained centrifugal pump transfers the water mud to the de-sander/de-silter cyclone for finer solids parting. After separated by the cyclone units, the clean liquefied would overflow to any where customer prefer.
bored pile desander
GN’s de-sanding unit is classified because 200GPM, 500GPM and 1000GPM with different model as GNMS-200D, GNMS-500D and GNMS-1000D.

About consideration of cost conserving and flexibility, this de-sanding system is not equipped with mud storage space tank. The operator might get the mud tank in your area and connect with GN’s de-sanding unit easily with pipe. The operator even can obtain a separate skid mounted airliner mud mixer to connect having mud tank to amalgamated a complete mud recycling program. Thus the user could get a new self-contained mud system which may be used for horizontal directional going which will request for both soil recycling and mud mixing.
Considerably better solution for your piling job mud recycling, for more information, make sure you no hesitate to contact along with GN Solids Control.
