The client is local drilling client for HDD project. The client is providing water well drilling contract to government companies, government oil drilling companies etc. Last year in Feb, 2015, the client bought two sets mud cleaning system. Each set mud system only with one mud recycling tank, mounting with one set shale shaker & one set mud cleaner.

Recently, the client is requiring one more compact mud system for water well drilling, 500gpm system with two tanks. One shaker tank is with shale shaker and mud cleaner, one mud mixing tank with agitators or centrifugal pumps.


Simple introduction of GN 500gpm mud system as below.

One shale shaker mud tank system including: one set shale shaker, one set mud cleaner, two sets centrifugal pumps. The shale shaker is GN patent 3 panel shale shaker, which have over 5 years jobsite experience. The shaker can work well in different hard conditions. The mud cleaner is GN 3 panel mud cleaner with GN compact design, down deck shaker and desilter cones. Another tank is mud mixing tank with mud agitators, mud guns and mud hopper for chemical mixing.

Except for this mud system, GN drilling waste management equipment is also very popular in the world.

Waste management centrifuge: GN decanter centrifuge is working after replacing USA brand centrifuges. The centrifuge can work for solids control, waste management, waste water treatment ect.  In solids control application, 2500rpm is generally used for mud weight cutting, and 1800rpm to 2000rpm is generally used for barite recovery.  In drilling waste management, 2500rpm to 3000rpm is generally used for removal the fine solids. In waste water treatment, higher speed centrifuge is required after chemical enhancement.

Vertical cuttings dryer is also called VG dryer, VG dryer can treat the drilling cuttings discharged from shale shaker, the OOC after VG dryer can reduce to about 3% to 5%, and the dry solids can be collected by cuttings skips and transport by trucks to a cuttings center for final treatment.

GN high G shaker for water based mud drilling cuttings treatment, have two models for choose. One model is only High G shaker without beneath tank.  In this case, the operator should design one cement pit or separate mud tank to hold the liquid part after High G shaker.  The other model is High G shaker with beneath tank for fast use.

After High G shaker, high speed and variable speed centrifuge will be used for fine solids separation. GN Solids Control design decanter centrifuge with height adjustable skid for convenient use.

Recently, we have one drilling waste management service customer who buys 1 sets high G shaker with beneath tank and 1 set variable speed centrifuge with high skid. The detailed technical specifications as below:

1) High G shaker with beneath tank: The shaker is GNZS594HGE-LD shaker with 4 panel shaker screen (composite material frame screen and steel frame screen both available). The drying time should be longer than 2 panel or 3 panel shaker, and the performance should be much better. The shaker with hopper type feeding, total height is much lower than weir type feeding or box type feeding, match better with drilling cuttings treatment job.

GN Centrifugal pumps with star-delta starting control panel are widely used in different jobsites in oil & gas field. The centrifugal pump can used for mixing bentonite, transferring drilling mud in solids control system, charging mud pump and working instead of mud pump is some special cases.

gn centrifugal pump for mixing bentonite

1) The pump control panel

For small pump with below 22kw motor, generally direct starter is OK.

For bigger pump with motor between 30kw to 75kw, star-delta starter is necessary. These kinds of starter will lead to high prompt start current and then the current will go down to normal degree after normal operation.

For larger pump with above 55kw motor, soft starter is recommended for easier operation. These kinds of starter current will arise smoothly and no need much bigger generation to match.

2) Centrifugal Pump quality

Welcome to contact GN solids control if you are interested to apply for our distributors in Venezuela. GN solids control is a young but fast developing company and we are solids control specialist in China. We have exported many sets of drilling mud cleaning and recycling system to South American regions, for example, Brazil, Colombia, Venezuela, Argentina, Ecuador, etc.

solids control system in Venezuela

solids control system in Venezuela

Perhaps the most important thing to know about Venezuela is that it is an oil exporting country, the fifth largest in the world, with the largest reserves of conventional oil (light and heavy crude) in the western hemisphere and the largest reserves of non-conventional oil (extra-heavy crude) in the world.

GN manufacture complete line solids control equipments for the drilling rig( shale shaker, desander, desilter, mud cleaner, vacuum degasser, decanting centrifuge, mud pump, poor boy degasser, mud gun, mud agitator, mud mixer,mud tank), and we can provide a complete solution on drilling waste management( high G dryer, decanter centrifuge, screw pump, vertical cutting dryer, mud tank, etc). As government policy is more and more strict on environment related on drilling, our equipments are more and more important recently.

All of the foregoing sets the stage for showing just how extremely important the country’s conflict over oil is. At the most overt level, the conflict between the Chávez government and the oil industry is one about who controls PDVSA. Beyond that, the specific issues that control is being fought over have to do with the company’s efficiency, its internationalization program, its outsourcing and subcontracting practices, OPEC membership, and special oil contracts.

PDVSA, State owned company in Venezuela

PDVSA has a production capacity, including the strategic associations and operating agreements, of 4 million barrels per day (600,000 m³). Officials say production is around 3.3 million barrels per day (520,000 m3/d) although most secondary sources such as OPEC and the EIA put Venezuela’s output at least 500,000 barrels per day (79,000 m3/d) lower.

Mud recycling system is important in hdd boring,  how mud travels in hdd no dig system, is always a problem people may ask. And then, we concern what GN Solids Control can supply, and who all over the world have chosen GN.

How mud travels in hdd no dig system

The mud is born clean, it was mixed by bentonite and some chemical mixtures, then stored by a tank. Ready to go to the hdd no dig system. Then it was pumped to the pipe and to boring the hole, later it was bring back by the pipe to a storage tank with all the hdd no dig mud recycling systemcuttings rocks and sands.
The mud recycling is needed now, the drilling mud with sands and drilling cuttings are pumped to the system, then the cleaned mud return to the pipe.
The mud recycling is usually including shale shaker, mud cleaner, or desander and desilter instead, sometimes decanter centrifuge is also needed. The drilling mud flow through the shale shaker, desander cones, desilter cones, then the decanting centrifuge.

All units within the range use two processes when cleaning mud to ensure the drilling fluid can be recycled and used to the efficiency of the first time it is pumped down the hole.

The first process is with the use of a shaker screen. When the mud is drawn from the hole it is first discharged onto a fine mesh, which constantly moves from side to side spreading the mixture across it. This allow the drilling fluid to fall through whilst larger items such as rocks and cutting remain on the mesh until they are shaken off its bottom edge and removed from the system.
