Bentonite drilling mud is the most common typereferred to as gel. When being pumped, this
is a very thin and free flowing fluid. When pumping is stopped, the static fluid builds a gel
structure that resists flow. It is known as a viscosity controller.used

In this lab, there were two primary objectives. The first objective was to recognize the effects of
lime, salt, and gypsum treatment on a drilling fluid. The secondary objective was to measure
alkalinity of a mud with a pH meter and tes

Executive Summary:
The purpose of this experiment was to better understand different properties of drilling fluid and
how they relate to drilling. In this experiment, we measured fluid density of different substances
using a mud balance. We also compared

The primary objective of this lab was to learn how to analyze the chemical content of a drilling
mud by using routine field tests. In order to do this, my group obtained a drilling mud with an
unknown contaminant. To do this, we collect

Executive Summary:
In this experiment, our main objective was to measure the sand content of a mud sample. To do this, my group
used a retort system and a sand content kit. Another objective was to simulate the buildup of a filter cake in a
