1.Overview
The Model HSHD-821 Rig Laboratory is a drilling fluid analysis kit designed to serve as a work station where wellsite personnel can carry out the usual standard drilling fluid checks.
The standard 821 Rig Laboratory includes testing equipment to test drilling fluids for weight, marsh funnel viscosity, filtrate volume, pH value, sand content, and chloride ion concentration. The equipment for the 821 Rig Laboratory is contained in a durable, compact stainless steel cabinet.
The 821 Rig Laboratory is designed to give the drilling fluid engineer convenient access to all testing equipment, and the cabinet and equipment are built for long life and easy maintenance under field conditions.
The standard drilling fluid tests included in the Rig Laboratory are described individually. The discussion of each test includes a description of the equipment, a detailed testing procedure, and information concerning the care and maintenance of the equipment. The Rig Laboratory should be mounted on a wall, or placed on some surface, so that the cabinet is approximately level and the work table at a convenient height when standing in front of the cabinet.
