Abstract
A process for the separation of oil from invert mud drill cuttings. Invert mud drill cuttings are supplied to a mixing chamber of a jet pump. The invert mud drill cuttings are agitated within the jet pump to effect transformation of the solids-oil matrix of the invert mud drill cuttings. Oil is then separeated from the transformed solids-oil matrix in a separator.
Claims7
A process for phase separation of invert mud drill cuttings containing a mixture of a solids-oil matrix and a water fraction, the process comprising the steps of:
- supplying the invert mud drill cuttings to a mixing chamber of a jet pump;
- agitating the invert mud drill cuttings within the mixing chamber by operation of the jet pump to effect a matrix transformation of the solids-oil matrix;
- supplying the invert mud drill cuttings containing the transformed solids-oil matrix to a separator;
- and
- separating the oil from the transformed solids-oil matrix in the separator.
