The principal factors governing the selection of type (or types) of drilling fluids (mud) to be used on a particular well are: The characteristics and properties of the formation to be drilled The quality and source of the water to be used in building the fluid The ecological and environmental considerations Continuous-Phase Classification. Drilling fluids …
Various properties of the drilling fluids are measured as an indication of the performance of the mud in the hole. Methods for measurement of these properties are stated in API RP 13B “Recommended Practice on Standard Procedure for Testing Drilling Fluids” (Check Also WBM Testing Procedure – OBM Testing Procedure). These procedures are revised and …
Drilling muds are designed to facilitate drilling operations and provide proper cuttings transport. They are not necessarily conducive to efficient mud displacement, logging, or completion operations. Therefore, it is often necessary to condition the mud (i.e., to modify mud properties). Before placing cement (Cementing in drilling) in the wellbore, two mud characteristics can be changed—density …
Yield Point in drilling mud is defined as the measure of the fluid’s initial flow resistance or the calculation of a value required to move the fluid in terms of shear stress. It can also be stated that the yield point is equivalent to the force of attraction between the particles of fluid colliding with …
OBM oil-based mud requires special chemical additives to ensure that the emulsion is extremely stable and can withstand conditions of high temperature and contaminants. Oil mud products must be dispersible in the external oil phase. We believe you might also like this article (Baroid Drilling fluids). The major OBM oil-based mud chemical additives that will …
The term bentonite in drilling mud fluids was derived from the location of the first commercial deposit in the United States. In 1897, Knight reported that since 1888 William Taylor of Rock Creek, Wyoming, had been selling a “peculiar clay” found in the Fort Benton shale of Cretaceous age. Knight proposed the name “taylorite.” On …

In California, barite was first used in a well being redrilled with cable tools in 1923. According to the report, the density of the mud was raised to 90 lb/ft3 (1.44 g/cm3 ) to control the gas inflow and to stop caving. Here in this article, we will discuss the major knowledge that drilling engineers …
There are a lot of Water Based Drilling Fluid systems that are used in drilling oil and gas wells. In this article we will talk about the following fluid systems: Spud Mud Spud mud is a simple Bentonite (Gel) mud system that is used when spudding a well to drill the top-hole section. Surface formations …
Mud Engineers & drilling engineers need to have quick drilling fluid calculations equations to help them while they are on the rig. In this article, we will have a simple guide for the most used equations for drilling mud preparations, system, displacement, volumes, etc. Density and Specific Gravity Calculations For mud The density of a …
