9m ft Inner Tubes Fiber glass & aluminium barrel Coring Tools Used for Oil Coring


Horizontal coring tools

The tool coring in the horizontal well, in order to prevent the inner cylinder rotation, the rotating assembly and the drill throat specially designed radial righting bearings to ensure that the coring tool double cylinder single action, the outer drum on the drum-shaped straight edge stability Stabilizer is conducive to stability, to minimize the scraping of the shaft wall and the friction from the drill. The maximum curvature through the wellbore is 48°/100M.

Oil Core Barrel:


1. 9m ft. Inner Tubes Fiber glass & aluminium barrel

  • Core barrel- 6 3/4” x 4”, inner tubes- O.D-4 3/4”, I.D-4 1/4”
  • Core barrel- 5 1/2” x 3 1/4”, inner tubes- O.D-4”, I.D-3 1/2”

    2. Coring tool with TSS

7 1/8” Core Barrel size that’s mean 4” size of core.


Fiberglass Inner Tubes

Fiberglass inner tubes provide low friction core entry and are suitable for all applications including soft or fractured formations or even hard and abrasive formations. Fiberglass inner barrels do not react with chemicals and should be used in high H2S applications. They facilitate ease of cutting when processing the core into one meter lengths and require no special saw blades or lubricating waxes. They can be used in wells with static temperatures as high as 302°F (150°C). And with these tubes as well as aluminum inner tubes, one-way pressure relief valves can be installed for venting gas from the inner tube to the annulus of the core barrel as the core is being pulled to surface. 

The PosiCloseTM system (patented) is designed to maximize core recovery in soft, unconsolidated formations. Unrestricted entry eliminates jamming from premature catcher-core contact. The catcher system fully closes to ensure complete retention throughout retrieval

LEFT. At the surface, SPP (stand pipe pressure) while coring. MIDDLE. Ball is dropped from surface when coring run is complete. Clear surface indication that catcher system is unlocked and ready. Hydraulic pressure increases and lifts inner sleeve to expose core to catchers.

RIGHT. Clear indication at surface when catcher is activated by stroking upper sub. Internal lower mechanism forces clam shells to shut, cut and seal-off core.

LEFT. Inner sleeve provides smooth, unrestricted bore for core entering the inner tube, which prevents jamming from premature contact with both core catchers. MIDDLE. Inner sleeve lifted after ball drop from surface, system ready to engage core. RIGHT. Clam shell catcher closes fully to cut and retain core, actuated by upward movement of the drillstring. If clam shells do not cut core, the conventional spring
core catcher catches core in the standard method.
