Definitions

  • the present invention relates to a method of and apparatus for evaluating lost circulation materials.
  • the drilling mud is fed into the larger aperture of an open-ended wedge-shaped slot in a test cell until a sealing plug is formed in the slot by the lost circulation material, pressure then being applied to at least one of the walls of the wedge-shaped slot, the pressure tending to close the slot, the pressure then being removed from the wall or walls and further mud being fed into the larger aperture of the wedge-shaped slot to determine whether the previously formed sealing plug is still providing an effective seal.
  • this pressure is gradually removed and gas pressure is applied to the rear of beam 15 via pressure inlet port 24.
  • the gas pressure is applied via valve 44 in control panel 43 from the gas cylinder, the valves 42 and 49 in control panel 43 being closed.
  • the gas pressure is increased to predetermined maximum (for example lbs. per sq. in.). and maintained for a certain time (for example 30 mins.) after which it is released and the hydraulic pressure reapplied to the reservoir 13, as previously described, attempting to reach the predetermined maximum pressure.
  • the hydraulic pressure is reapplied to determine if the sealing plug remains effective after the compression which simulates induced fracture conditions.
  • test cell includes a rigid movable member having a plane surface arranged to act as said adjustable wall surface and co-extensive with the length of the slot.
  • Apparatus according to claim 2 which includes movable elements coupled to said movable member adjacent to each end thereof, and indicating means linked to said movable elements and arranged to provide an indication of the dimensions of said slot at each end thereof.
