Drilling rig with a modular wellbore strengthening material recovery system

A drilling rig with a modular wellbore strengthening material recovery system, comprising:

• a. an active drilling fluid tank system, a power supply, and an on-rig shaker connected to the power supply, for separating and containing a shaker underflow and on-rig shaker waste, and a waste containment system;
• b. a pump mounted to the drilling rig fluidly receiving an on-rig shaker effluent forming a pressurized on-rig shaker effluent, the pressurized on-rig shaker effluent having an adjustable hydraulic head;
• c. a motor for driving the pump connected to the power supply;
• d. at least one high solids capacity accelerated settling device configured to receive the pressurized on-rig shaker effluent at a constant head ranging from 20 feet to 125 feet of head, forming effluent and an accelerated settling device underflow has a capacity of from 700 gallons per minute to 2100 gallons per minute removing wellbore strengthening material;
• and
• e. a recovery shaker connected to the power supply, the recovery shaker receiving the accelerated settling device underflow, the recovery shaker comprising:
• (i) a top vibrating screen deck;
• (ii) a bottom vibrating screen deck;
• and
• (iii) a vibrating back flow pan fluidly connected between the top vibrating screen deck and the bottom vibrating screen deck, the recovery shaker separating:
• (iv) a recovered wellbore strengthening material from the top vibrating screen deck flowed into the active drilling fluid tank system, wherein the recovered wellbore strengthening material comprises particles with a diameter from 0.01 inches to 0.75 inches;
• 1. a top screen filtrate from the top vibrating screen deck flowed through the vibrating back flow pan to the bottom vibrating screen deck;
• 2. a bottom screen effluent from the bottom vibrating screen deck recycled to the active drilling fluid tank system;
• and
• 3. a waste transferred to the waste containment system.
