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.

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.

GN new designed BEM mini mud cleaner, it is special for small handling capacity mud system, such as HDD(horizontal directional drilling), water well drilling, desanding unit and small workover rig mud tank system.

GN BEM mini mud cleaner GNPJ752 Features:

1 with 2 panel shaker screens at API 60~80 mesh size, total screen area 1.35m2

2 vibration motion: BEM( balanced elliptical motion), which is the lastest technology, BEM shaker’s treating effect is better than traditional linear motion shaker.

3 With 4” desilter cone to separate 20 microns solids, cone qty is optional, 4pcs, 6pcs, 8pcs, 12pcs, depends on the handling capacity you required.

Or with 10” desander cone to separate 75 microns solids, cone qty is optional, 1pc or 2pcs, depends on treating capacity.

4 2ea Italy Oli vibration motor 0.7HP

5 Pretentioned shaker screens are locked by wedge, which is very convenient to replace shaker screen
