  • Method and apparatus for reclaiming drilling fluids from undesirable solids in a drilling operation
    Patent number: 4636308
    Abstract: A method and apparatus for use in a well drilling operation where drilling fluids are used and recycled. More particularly, it relates to novel method and apparatus for reclaiming valuable drilling fluids otherwise discarded with solids.
    Type: Grant
    Filed: June 13, 1985
    Date of Patent: January 13, 1987
    Inventor: Don D. Summers
  • Method and apparatus for self-cleaning drilling mud separation system
    Patent number: 4234413
    Abstract: A vibratory separator for separating drill solids from drilling mud after return from the well bore, including a separator screen and a screen cleaning device positioned adjacent the screen. The screen cleaning device is supported by suitable means to permit filtered mud to pass freely through the device for collection below. The screen is a fine wire mesh mounted in a unique manner to the separator housing such that it vibrates during operation of the system to keep drilling solids from clogging the wire mesh and restricting the flow of drilling mud. The screen cleaning device serves to support the screen and mud thereon in addition to vibrating and wiping the screen as the device rotates due to the orbital oscillatory vibrations of the system.
