At the top is basic information about drilling hardwareâthe drill string, mud flow, bit data, and solids control equipmentâand cuttings retrieval. On the left are mud prop- erties and on the right is mud volume analy- s.s. At the bottom is information about sup p ies and mud on hand pertinent to drilling
Â¾ Mud should posses properties that help evaluate these properties Drilling mud Â¾ Fresh water gives a pressure gradient of 0.433 psi/ft Â¾ Normal formation pressure gradient is 0.465 psi/ft Â¾ Fresh water can not control formation pressure Â¾ Solids are added to increase water density to control pressure Types of drilling mud Water base mud Â¾ Consists of: â¢ Liquid water, continuous phase â¢ Reactive solids, for viscosity and yield point â¢ Inert solids, for density â¢ Chemical additives, to control properties Reactive solids
