LNCO is involved in the field of supplying consumable equipment for Oil & Gas Drilling Industries.
1: Oil and Gas Drilling Equipment
 
1.1: Well Head Equipment
1.2: Down Hole Equipment
 
1.1.1: Well Head Equipment and Rig Drilling Tools
 
Oil and gas drilling rig equipment such as: Crown Block، Derrick، Subbase، Draw works، Rotary Table، Mud Pumps، Power Generator، Blow Out Prevention (BOP) ،Commy Unit،Travelling Block ،Top Drive and Kelly.

1.1.2: Well Head Equipment ( X- Mass Tree )

After the oil  and gas wells are closed, for controlling and  exploits the well, number of equipment are used directly on the Top of the well ( X – Mass Tree ) or around the well with connection to the well head ( X- Mass Tree ).  
(X-Mass Tree) components:
  • Base Flanges
  • Side Valves
  • Bottom Main Valve
  • Top Main Valve
  • Surface Safety Valve

1.2: Downhole Equipment: 
Downhole Drilling equipment used in the oil and gas wells are as follow: Drill Bits,Drill Pipes, Heavy weight  Drill pipes ,Drill collar ,Jar Pipes , Stabilizers, casings, Pup Joints, Tubings,Liner, and PDM.
Our company is more involved in supplying those Downhole equipment which are consumable as follows:

1: Drills Bits

Drill bits are divided into different categories:
1.2.1.1: Drag Bits
1.2.1.2:Diamond Bits
These Bits Sizes are available from  to  Inch as follow:
PCD: Polly Crystalline Diamond
TSP: Thermally stable Polly Crystalline

Rock Bit tri-cone Rock Bit Rock Bit
  •  TCI(Tungsten Carbide Insert Tooth Bottom Bits): these bits sizes usually available from  to 30 inch.

1.2.2:Casing Types

Casing Types are classified according to Table 2
Table2:Specifications and Nominal Sizes

 

Casings are available in various degrees according to Table3 ,API standard
Table3: specifications of casing grades

 There are some Casings and Liners in below pictures:

                 Casing                                

Casings are used to prevent fragile formation whenever we are drilling formation. Liner is a kind of casing that doesn’t com to the surface. Liner hang in intermediate casing and suspend by a set of packer and slips to liner hanger 
1.2.3: Tubing

These pipes are used after the wells are drilled and the tubes are used to fill the well to use the oil layer.These tubes have a smaller diameter than liners.
Bottom of the Tubings are installed into the oil layer in the ground and tubing sizes are usually about 1 – 2 7/8 Inch, and depend on well physical parameters these tubings are perforated. The perforated type used for transmission fluids into tubings.

1.2.4: Liner Hanger      
                                                                           

Aliner hanger is a device used in oil fields to hang liners within and oil well  So that oil can be pumped out of the well, a liner is used to create a vacuum. Liners can be installed mechanically or hydraulically, depending on the well. Setting a hanger is a crucial part of the process of "completion" which is the preparation of an oil well for drilling. These tools is available in size of 7,5 and 4 1/2 inches.

1.2.5: Drilling Pipes:

Drill Pipe, is hollow, thin-walled, steel or aluminum alloy piping that is used on drilling rigs. It is hollow to allow drilling fluid to be pumped down the hole through the bit and back up the annulus and these are most useful equipment in drilling operations is drilling pipes that its amount and sizes is vital. It is used in different sizes as,,5,inch ,and with considering oil well profile position.

1.2.6: Heavy Weight Drill Pipe

Heavy Weight Drill Pipe. (HWDP) may be used to make the transition between the drill collars and drill pipe. The function of the HWDP is to provide a flexible transition between the drill collars and the drill pipe. This helps to reduce the number of fatigue failures seen directly above the BHA.It is available in following sizes: 2 7/8,3,3 1/2,5, 6 1/2.

1.2.7: Motor Turbine Drill and Positive Displacement Mud (PDM)

The positive displacement motor (PDM) has been used in directional drilling now for several years and is a key component in bottom hole drilling assemblies. These downhole drilling motors, coupled with Measurements While Drilling (MWD) tools and proper stabilization allow directional wells to be drilled with one bottom hole assembly, eliminating costly multiple drill string tripping, which in the past was necessary for surveying, hole corrections, and stabilized assemblies.

		1.2.8  :Jar Drill Pipe 
 Mechanical device used downhole to deliver an impact load to another downhole component, especially when that component is stuck.
There are two primary types, hydraulic and mechanical jars. While their respective designs are quite different, their operation is similar. There are available from 3 1/2 to 8 1/2 inch with high grade steel.
Hydraulic Jar Pipe
1.2.9:Drill Collar:

drill collar is a large-diameter, heavy pipe used in oil drilling that fits around the drill string and puts weight on the drill bitand it’s is the most widely used equipment after drilling pipes which have a very important role in well drilling, Because of high weight, It increases weight and drilling speed. These are available is sizes of:,,nch  and should be available on the rig.
