Understanding Solid Analysis in Unweighted Drilling Fluids Unweighted drilling fluids, such as heavy brine or water, are commonly used in drilling operations. As the fluid circulates through the wellbore, it picks up drilling cuttings, which are referred to as solids. These solids are typically removed by equipment like shale shakers. However, smaller particles may not…
When drilling engineers talk about mud rheology, one model always comes up: the Bingham Plastic Model. It’s simple, useful, and has guided hydraulics calculations for decades. But there are two ways to determine its key parameters — and depending on which way you choose, you may get different answers. Let’s unpack this. Step 1: The…
If you’ve ever worked with drilling fluids, you’ve probably heard — or even used — the shortcut: Plastic Viscosity ( PV ) = θ 600 − θ 300 But have you ever asked: why? Where does this come from? Is it just a field trick, or is there solid fluid mechanics behind it. In this…
Emulsifiers in Oil-Based Mud: A Comprehensive Explanation: Emulsifiers are surfactants (surface-active agents) composed of molecules with a hydrophilic (water-attracting) head and a hydrophobic (oil-attracting) tail. They stabilize mixtures of immiscible liquids, such as oil and water, by reducing interfacial tension and preventing separation. Emulsion is a major part in an oil-based drilling fluid. An emulsion…
Rheology is the study of the flow and deformation of matter, particularly fluids. In the context of drilling fluids (commonly referred to as “mud”), rheology is crucial because it influences the efficiency and safety of drilling operations. Drilling fluids are complex mixtures that can include water, oil, clay, polymers, and various additives. Their rheological properties…

The canvas element is a powerful tool for creating graphics and interactive visual elements directly in a web browser. It is a container for drawing graphics using JavaScript. Unlike traditional image elements, the canvas element is dynamic, allowing developers to draw, manipulate, and animate content programmatically. Key Features of HTML Canvas Drawing Shapes: You can…
