Not only for drilling application( oil & gas drilling, HDD, geothermal, CBM, water well drilling), GN equipments can be also used for mining slurry separation, dredging slurry management, piling and tunneling.

Dredging and Dewatering equipments

Dredging and Dewatering equipments

GN dredging and dewatering equipments are designed to feed slurry directly from the dredge. GN dredging slurry separation system separates solids from dredging slurry through a three phase system.

In addition, the solids that are removed are dewatered to a stackable “press filter” state, which can be readily moved with front end loader, conveyor and/or dump trucks. The effluent is pumped off by a centrifugal pump.

The separation process is continuous and operates completely mechanically without any chemical enhancement. The dredging slurry separation system is designed as a three phase separation system, 1st separation is shale shaker, 2nd separation is desander, 3rd separation is desilter. Sometimes as the client’s requirement, we only design 2 phase shale shaker and desander. The desander and desilter are made into separate mud cleaner with large screen area.

The mud cleaning system produced by GN solids control is widely used for horizontal directional drilling , water welling drilling ,coal bed methane, geothermal hole and mining diamond core drilling , it is used to separate the drill cuttings from the mud, so that the clean mud can be re-circulated to continue the drilling process.

As the Geothermal drilling usually close or inside the downtown, this requires the mud system to be compact with less footprint and user friendly with less noisy. Also Geothermal well drilling sometimes require high capacity performance for deep wells. Below is the jobsite photo of mud cleaning system for geothermal drilling, which is produced and commissioning by GN solids control.

Like water well drilling, mud rotary drilling is also the desired method for installing geothermal loops. As the bit penetrates the soil, it creates smaller fragmented pieces that are called drill cuttings. The mud carries these cuttings to surface to create an open hole from the top down to the bottom. The drill cuttings are collected into a mud pan or settling pit on surface and then the mud is re-circulated to continue the drilling process.

MI-SWACO CD-250 centrifuge is designed for the purpose to solve a problem that there is no proper model centrifuge for small drilling process application with a compact dimension, for example, HDD, diamond core drilling for mining. It should meet 3 important points: 1 high separation efficiency, 2 tight space, 3 economic solution. GNLW220 centrifuge is designed for the similar purpose.

Directional drilling (DD) is seen as a marriage of conventional road boring and the directional drilling of oil wells.

It is also known as directional boring, horizontal drilling, slant drilling, or deviated drilling, is a method of trenchless technology that involves drilling a non-vertical well or borehole. It can be broken down into three main groups: Oilfield Directional Drilling, Utility Installation Directional Drilling (or H.D.D. or Horizontal Directional Drilling) Directional boring, and in-seam directional drilling to extract coal bed methane.

directional drilling machine

Many directional boring machines also use a drilling fluid or slurry called mud. Other machines use foam or air, or both. The drilling fluid or mud is composed of bentonite clay and water with additives for enhancing performance. The higher-pressure jet of fluid is used in soft ground to cut through the soil. The cuttings then get suspended in the fluid. As more fluid is pumped down into the hole, the cuttings are brought back up to surface where they settle in a pit or are removed mechanically.
GN solids control equipments are used to handle the drilling mud with cuttings, to separate the big cutting out of the drilling fluids, so that the mud can be used for drilling again.

For oilfield directional drilling, we provide a complete solids control system, including 4-class cleaning of mud, shale shaker – desander – desilter – centrifuge, sometimes vacuum degasser is applied.

Directional boring has evolved steadily over the last 20 years and is now the preferred method on many installations due to its low cost and low impact on surroundings.

GN solids control will ship a complete directional boring mud recycling system to Brazil for application. The directional boring equipments we produce including HDD mud system, shale shaker, mini mud cleaner, desander, mixing pump, jet mud mixer, etc.

Directional boring, commonly called horizontal directional drilling or HDD, is a method of installing underground pipes and conduits along a prescribed bore path from the surface, with minimal impact to the surrounding area.

GN direction boring equipments application

The process is used for installing telecommunications & power cable conduits, water lines, sewer lines, gas lines, oil lines, product pipelines and environmental remediation casings. It is used for crossing waterways, roadways, shore approaches, congested areas, environmentally sensitive areas and any area where other methods are more expensive.

They have been used in Australia, Indonesia, Brazil, France, Singapore, application including HDD, diamond drilling, water well drilling. Our directional boring equipments have been showed in Australia no-dig show, and it is approved by many HDD operators. We will take another set of HDD mud cleaning system in CIPPE ( world’s largest oil show) held in Beijing, if you want to check its performance, pls visit us in CIPPE.

There’s a lot to consider when purchasing or leasing a horizontal directional drill — features, durability, support, training and overall value. But one area often overlooked is the potential resale value of the unit.
Too often contractors will overlook the potential value of the machine after its useful life in their operation is over. In addition, as more contractors utilize leasing as an acquisition strategy, resale value becomes a more important component in the purchase decision.

Vermeer has distributor everywhere in the world, you can get good after-sales service from them easily.

For HDD(Horizontal Directional Drilling),People sometimes uses Truck mounted drilling mud system for recycling drilling mud while drilling.The trenchless drilling mud system is usually very portable with small treating capacity,but very convenient for moving.

Inquiry for truck mounted drilling mud system shaker.

Truckmounted mud system

Truckmounted mud system

I’m assembling a drilling support vehicle (truck with mud system)  here and plan to install a mud shale shaker on the truck. This is for geothermal drilling. The advice I am getting from our polymer specialist is that for our typical geologies here in UK ( clays and shales ) the cuttings can be removed – if using a fine enough screen - directly by the shale shaker. ( i.e. the polymer ecapsulates the cuttings and we do not plan to use a de-sanding(desander) or de-silting (desilter) cyclones above the shaker ).
For the truck mounted mud system a shale shaker is being proposed to us with a high capacity is fitted with 5 screens. So although our flow is only 40 m3/hr ( 170 GPM) but the shaker nominal treating capacity  is 3 or 4 times higher.
This approach interests me but I think that the shale shaker which may be proposed to me will be more than my budget. I am interested in your equipment for truck mounted drilling mud system and I would be most grateful if you would advise me of: Continue reading »
