ABSTRACT

The density of any fluid is directly related to the amount
and average specific gravity of the solids in the system. The starting point of
pressure control is the control of mud density. The weight of a column of mud
in the hole necessary to balance formation pressure is the reference point from
which all pressure control calculations are based. The required weight of the
mud column establishes the density of the mud for any specific case (EXXON
COMPANY, 1996).

INTRODUCTION

The purpose of this experiment is to find the density or weight of a
particular volume of mud. A mud balance is used. The balance is made in a way
that the fixed volume cup at one end of the beam is balanced by a fixed counter
weight at thr opposite end.

Procedures

1.
Place the mud balance on a
leveled surface.

2.
Fill up the clean, dry cup to
the brim with the test fluid

3.
Place the lid on the cup and
set it with a gentle twisting motion. Be sure the mud is expelled through the
hole in the cup to make sure the cup isfull and without air space or gas.

4.
Cover the top of the hole with
your finger and clean the surface of all mud . then dry the entire balance.

5.
Place the balance on the edge
of the knife and move the rider along the outside of the arm till both the arm
and cup are balanced as shiwn by the bibble.
