  • Patent number: 10132140
    Abstract: A method for injecting a portion of a drilling fluid waste into a well includes separating solids from the drilling fluid waste to produce a filtered drilling fluid waste. A cross-sectional dimension of at least a portion of the solids is reduced. The filtered drilling fluid waste is combined with the at least a portion of the solids that were reduced in dimension to produce a slurry. A property of the slurry is measured. The property is adjusted in response to measuring the property. The slurry is injected into the well.

  • Patent number: 10087711
    Abstract: An apparatus for selectably isolating a subterranean formation from a production string comprises a radially expandable ring located between upper and lower sleeves and retained at a position to intrude into a central passage extending therethrough. The expandable ring is permitted to radially expand into a recess upon displacement of the lower sleeve to permit a body retained thereon to move therepast. The apparatus includes a pair of inner and outer indexing rings which cooperate to permit the inner and outer indexing rings to move towards a bottom end thereof only to a fixed endwall whereafter further movement of the inner and outer indexing rings and lower sleeve is prevented.
