  • Oil-based drilling fluid recovery and reuse
    Patent number: 8997896
    Abstract: Methods and related systems are configured to treat a drilling fluid to cause water droplets to coalesce. One or more phases are thereafter separated from the treated drilling fluid. The oil and/or solids separated from the treated drilling fluid may be added to a base fluid.
    Type: Grant

  • SYSTEMS AND METHODS TO REMOVE HYDROCARBON OILS FROM CONTAMINATED DRILL CUTTINGS
    Publication number: 20140367501
    Abstract: A system for treating drill cuttings may include a first stage that receives the drill cuttings and generates a first drill cuttings slurry and a second stage that receives the first drill cuttings slurry and generates solids. The first stage may include a mixer receiving at least one additive from at least one treatment fluid supply. The mixer mixes the at least one additive with the drill cuttings to form a drill cuttings mixture and reduces the drill cuttings to a predetermined size. The first stage also includes a separator receiving the drill cutting mixture. The separator separates liquids from solids in the drill cuttings mixture to form the first drill cuttings slurry. The second stage may include a mixer that mixes a cleaning fluid from a second treatment fluid supply with the drill cuttings to form a second drill cuttings mixture. The second stage may also include a separator receiving the second drill cutting mixture.

  • POLYURETHANE ACTIVATOR-BREAKER FLUID SYSTEM
    Publication number: 20140332220
    Abstract: A combined activator-breaker fluid system is effective in oil and gas field applications to essentially simultaneously activate or deploy a shape-memory material and at least partially remove a polymeric filter cake left by a drilling mud, all in one step or trip.

  • METHOD FOR CLEANING DRILL CUTTINGS
    Publication number: 20120181085
    Abstract: One method for treating cuttings from a subsurface formation may include treating the cuttings with at least one surfactant and at least one stabilizing agent. The method may include contacting the cuttings with the stabilizing agent(s) before contacting the cuttings with the surfactant(s). Another method for treating drill cuttings includes returning the drill cuttings to a substantially water-wet condition by using at least one stabilizing agent to remove at least a portion of a hydrocarbon from the drill cuttings.
