Introduction The drilling fluid is related either directly or indirectly to almost every drilling problem. This is not to say that the drilling fluid is the cause or solution of all drilling problems, but it is a tool that can often be used to alleviate a problem situation. Many have thought that a magic additive would solve all of their problems and that the drilling fluid could somehow make up for poor drilling practices. This is simply not the case. It is a part of the drilling process and...

Relatonship Of Mud Properties To Functions

Yield Point Same Bending Capacity

In order to design and maintain a mud to perform a given function, it is necessary to measure the mud properties which control its ability to perform that function. For this reason, measurements are normally made on a variety of mud properties. Considerable research has been done to design tests and to correlate these tests with the functions of a mud. Normally, the functions of a mud are carried out downhole under conditions not easily duplicated in a mud test. Over the years, attempts have...

Functions of a There are a number of functions of a drilling fluid. The more basic of Drilling Fluid these are listed below 2. Carry cuttings and sloughings to the surface 4. Cool and lubricate bit and drill string In addition to these functions, there are several other functions with which the drilling fluid should not interfere Functions of a Clearly, these lists of functions indicate the complex nature of the Drilling Fluid Clearly, these lists of functions indicate the complex nature of the...
