Mud chemical delivery system and method
A silo, a chemical delivery system, and a method. The silo includes a housing and a vessel positioned within the housing and configured to contain a mud chemical. The vessel includes a discharge port and a discharge valve that controls discharge of the mud chemical through the discharge port. The discharge port is configured to connect to a skid by placing the silo on the skid, and the silo has a plurality of configurations for different types of mud chemicals.
1. A method for delivering a chemical to a drilling rig, comprising:
lowering a silo onto a base of a skid;
opening a discharge port of the silo using an actuator of the skid;
providing a plurality of discharge paths
selecting a discharge path for a mud chemical contained within the silo based on a type of the mud chemical;
delivering the mud chemical from the discharge port into the selected discharge path of the skid; and
directing the mud chemical from the selected discharge path to a mud mixing system and a drilling rig.
2. The method of claim 1 , further comprising acquiring data related to the mud chemical from an identifier of the silo using a reader of the skid, wherein:
the skid comprises a pneumatic discharge line, a conveyor, and a liquid discharge conduit;
selecting the discharge path comprises selecting the pneumatic discharge line when the data represents that the mud chemical is powdered, selecting the conveyor when the data represents that the mud chemical is coarse, and selecting the liquid discharge conduit when the data represents that the mud chemical is liquid; and
delivering the mud chemical from the discharge port into the discharge path comprises configuring the skid to direct the chemical to the pneumatic discharge line, the conveyor, or the liquid discharge conduit based on the data acquired from the identifier.
3. The method of claim 1 , further comprising adjusting a feed rate of the mud chemical using a valve actuator of the skid, in response to a mud property of mud in the mixing system.
4. The method of claim 1 , wherein the silo contains a mud chemical, a discharge port, and a discharge valve that controls discharge of the mud chemical through the discharge port, wherein the discharge port is configured to connect to a skid by placing the silo on the skid, and wherein the silo may contain different types of mud chemicals.
5. The method of claim 4 , wherein the silo further comprises an expansion system that adjusts to a change of gas volume inside a vessel when the silo is sealed and an air escape valve that is in communication with the vessel.
