For earth surface engineering,  the contractor no need to consider about combustible gas or explosive gas, like HDD no-dig engineering, piling engineering, tunneling engineering, waterway dredging engineering. But for deep drilling engineering, like oil & gas drilling, Coal bed methane drilling, shale gas drilling, all the motor and control panel should be ex-proof standard. The standard should also separately as per different geological conditions. Some security equipment is also necessary.

1) Mud Gas Separator ( poor boy degasser) — security equipment in solids control system for deep drilling

When gas cuttings happened to drilling fluid, the gravity and viscosity of drilling mud will be changed a lot and cannot satisfy the requirement for drilling, even lead to kick or blowout accident. The mud gas separator , made of high quality material , can be used to separate the harmful gas effectively.

GN Solids Control can supply the best quality mud gas separator with other solids control equipment, like shale shaker, decanter centrifuge, mud cleaner etc.

See the photo on the right, it is a mud circulation system with mud gas separator, in oil drilling solids control system, the 1st phase cleaning equipments of mud circulation system is shale shaker, which is fed the mud from high pressure manifold, the mud gas separator is fed mud from the chock manifold. When much of harmful gas is found during drilling, they close the valve to stop feeding the shale shaker, and open the valve to feed to mud gas separator, and use hundreds of exhaust pipe to transfer the harmful gas from mud gas separator to a place far from well head, and use flare ignition device to burn it. Mud gas separator is not a part of solids control system, GN can manufacture both of them, so we put them together for your convenience.

Mud circulation system is also called mud cleaning system, mud recycling system, solids control system, Usually if a mud circulation system with mud gas separator, it is usually oil & gas drilling or geothermal, it can not be HDD or water well drilling. Mud gas separator is horizontally installed on the skid with the chock manifold on it together, it is easy for transportation.

The poor boy degasser model in stock:



 Main body diameter




 Inlet pipe


 Mud Output pipe


 Gas discharge pipe






How poor boy degasser work to be anti-H2S?

( harmful gas , including but not limit to H2S)

1st way: The main material of the poor boy degasser body is 16Mn(Q345A), which is low alloy, high strength steel.

2nd way: By 3 layers of Marine Anti-Corrosion Zinc Rich Expoxy Paint:

(1). Sand Blast Treatment before painting.

(2). Two pack Epoxy zinc

(3). Two Pack Epoxy hi-build containing anticorrosive pigmentstwice.

(4). Surface pigmented with high quality light fast  PU pigments

To buy poor boy degasser in stock, welcome to contact GN solids control.

GN has 6 units of flare igniters in stock, they are widely used for oil & gas drilling operations, usually works together with GN own designed mud gas separator. The flare igniters are used for connecting to the gas discharge line of mud gas separator, and fire the dangerous gas from the drilling mud like H2S. GN manufacture the flare igniter according to API &ISO standard, which meet most of the oil industry applications.

The upper part of the flare igniter is stainless steel, and it is designed for rain proof , water proof in the oilfield. The major components for the electrics are from famous brand like Siemens or Schneider. The power of the electric can be directly from industry normal power, or users can charge the battery and take the unit for remote areas application. GN flare igniter is with remote control, and PLC is optional available for less manpower notice for continually and automatically working.

Gas buster also called poor boy degasser or mud gas separator, which is used for oil and gas drilling. The description on oilfield glossary is “A simple separator vessel used to remove free or entrained gas from fluids circulated in the wellbore, such as mud used during drilling operations. The gas buster typically comprises a vessel containing a series of baffles with a liquid exit on the bottom and a gas-vent line at the top of the vessel”.

Gas Buster

is an important equipment to prevent well kick during drilling, so the production process should be strictly controlled. The process control including the following aspects:

1 Surface preparation


Before all paint actions will be taken the surface to be coated must be clean and free from contamination. Sharp edges shall be rounded or smoothed to radius 2 mm. Hard surface layers shall be removed by grinding before blasting. All welds shall be fully sealed.

Abrasive Blast Cleaning:

As abrasive steel grit or copper slag can be used. If oxidation has occurred between blasting and application of paint, the surface should be reblasted to the specified visual standard.

Surface defects revealed by the blast cleaning process, should be ground, filled, or treated in the appropriate manner.

2 Painting
