Method, system and product of ultrasonic cleaning of drill cuttings

A method of cleaning drill cuttings having drill solids and drill fluid, said method comprising:

• characterizing said drill cuttings as having:
• (i) greater than 50% fluid composition or less than 50% fluid composition,
• (ii) solids texture being greater than 1 mm or less than 1 mm, and
• (iii) solids size being greater than 0.5 inch in diameter or less than 0.5 inch in diameter;
• determining a composition of a cleaning solution based on said characterization of fluid composition, solids texture and solids size, said cleaning solution being one of:
• (iv) a first formula having 1% surfactant and 2.5% viscosity agent when said drill cuttings have over 50% drill fluid composition and said drill solids have a texture greater than 1 mm and a size less than 0.5 inch;
• (v) a second formula having 5% surfactant and 2.5% viscosity agent when said drill cuttings have over 50% drill fluid composition and said drill solids have a texture less than 1 mm and a size less than 0.5 inch;
• (vi) a third formula having 1% surfactant and 3.5% viscosity agent when said drill cuttings have over 50% drill fluid composition and said drill solids have a texture greater than 1 mm and a size greater than 0.5 inch;
• (vii) a fourth formula having 5% surfactant and 3.5% viscosity agent when said drill cuttings have over 50% drill fluid composition and said drill solids have a texture less than 1 mm and a size greater than 0.5 inch;
• (viii) a fifth formula having 5% surfactant and 2.5% viscosity agent when said drill cuttings have less than 50% drill fluid composition and said drill solids have a texture greater than 1 mm and a size less than 0.5 inch;
• (ix) a sixth formula having 9% surfactant and 2.5% viscosity agent when said drill cuttings have less than 50% drill fluid composition and said drill solids have a texture less than 1 mm and a size less than 0.5 inch;
• (x) a seventh formula having 5% surfactant and 3.5% viscosity agent when said drill cuttings have less than 50% drill fluid composition and said drill solids have a texture greater than 1 mm and a size greater than 0.5 inch;
• and
• (xi) an eighth formula having 9% surfactant and 3.5% viscosity agent when said drill cuttings have less than 50% drill fluid composition and said drill solids have a texture less than 1 mm and a size greater than 0.5 inch;
• and
• treating said drill cuttings by:
• (xii) contacting said drill cuttings with said cleaning solution having a composition as determined for a preselected treatment time;
• and
• (xiii) applying ultrasonic vibration to said cleaning solution and said drill cuttings for a preselected vibration time.
