Coal Bed Methane (CBM) is natural gas contained primarily (about 90% -100%) of methane (CH4) found in coal seams. Methane is also the major component in petroleum natural gas (about 70% – 90%) that is widely used today. CBM is generated from the microbiological process or thermal process in the coal seam and recognized as one of the cleanest fossil fuels. Indonesia has one of the largest CBM reserves in the world with a potential 453 trillion cubic feet (“Tcf”), more than double the country’s natural gas reserves. The South Sumatra Basin, the largest CBM basin in Indonesia, is estimated to contain in-place resources of approximately 183 Tcf; and the Kutai Basin, the third largest CBM basin in Indonesia, is estimated to contain in-place resources of approximately 80 Tcf (SPE, 2004).

GN has exported many sets of mud tank system to Indonesia for CBM project. The technique to exploit CBM is different with that applied to the fossil natural gas, while both share the common in terms of marketing and utilization. Simply, CBM is exploited by drilling shallow wells into coal seams, dewatering the seams, extracting the methane from the seams and finally compressing the methane.

When design the CBM mud tank system, you should consider the following points:

1 shale shaker inlet method, usually the CBM well is lower than oil drilling well, maybe they will not use overhead manifold, but they have a mud pit and a submersible slurry pump to shale shaker.

2 fine particles, CBM drilling may contain much fine particles, most of clients will use high speed centrifuge.

3 Mud tank height, it should be a little lower than oil well drilling mud tank system.

GN solids control has designed and exported many sets of 1000HP land rig solids control system to worldwide clients for oilfield drilling, we have many existing design for their different requirement. Several clients called it “mud handling system”, “mud tank system”.

GN 1000HP land rig solids control system is including the following equipments:

1 Linear motion shale shaker or BEM shaker 2 sets, they can be made of dual tandem shaker

2 vacuum degasser with 1200gpm or 1600gpm treating capacity

1000HP land rig solids control system

1000HP land rig solids control system

3 Linear motion or BEM mud cleaner with 55KW centrifugal pump

4 high speed decanter centrifuge 1 set or middle speed decanter centrifuge 1 set, depends on budget

5 Twin Jet mixing unit with 2pcs mixing pump, max mixing rate can reach 200kg/min if they work at the same time

6 poor boy degasser with 1000gpm flow rate

7 Flare ignition device

8 Mud tanks: including shaker tank, settling tank, suction tank & reserve tank, water tank, fire tank, pill tank, trip tank, etc.

9 A complete set of electric control system, explosion proof grade IP56, other electric specs and explosion proof class are available.

Once we get the rig layout, we can arrange for the layout of mud tank system and submit process flow drawing and layout drawing of the solids control system. Our design may take the following aspects into consideration.

1 waste solids discharge: we will try our best to simple the solids discharge operation, and save land area of solids discharge, sometimes a screw conveyor is applied to keep the mud system in compact structure and convenience solids discharge.

2 transportation convenience:

 All the handrail and walkway are foldable and can be moved together with tank body, you do not need to disassembly it.

Brazil market is one of the largest market of oilfield drilling rig equipments, both for onshore and offshore drilling. We are always applying the exploration of Brazil market for our solids control equipments.

A news about “drilling in Brazil”:

The U.S. is going to lend billions of dollars to Brazil’s state-owned oil company, to finance exploration of the huge offshore discovery in Brazil’s Tupi oil field in the Santos Basin near Rio de Janeiro. Brazil’s planning minister confirmed that White House National Security Adviser James Jones met this month with Brazilian officials to talk about the loan.

We try to promote our new designed shale shaker and drilling fluids decanter centrifuge to Brazil. And develop a sole representative in Brazil to have some spare parts and equipments in stock, once they are needed, they can be provided to the client directly, we have bad experience to ship our goods to South America, it is too far and the air freight charge is too expensive. So to store some spares are the best way to solve the problem of after-sale service.

GN solids control sold the following drilling rig equipments in Brazil

1 oil & gas drilling solids control equipments

Such as shale shaker, desander, desilter, mud cleaner, decanter centrifuge, centrifugal pump, screw pump, mud mixer, mud agitator,etc.

2 design and manufacture Complete line of drilling rig mud tank system

3 After-sale service and spare parts

Such as shaker screens ( both for our own shaker and other brand shaker, Derrick shaker, NOV Brandt shale shaker, MI-Swaco shaker, Fluids system, KEM-TRON shaker, etc)

Union: hammer union and Pneumatic union

Hydrocyclone: Derrick 4” cone, GN 8” PU cyclone, 10”, 12” 100% PU hydrocyclone available
