The Density of a mud is the weight per unit volume expressed either in pounds per gallon or pounds per cubic foot. The density of the mud is important in order to maintain both the hydrostatic pressure as well as the pressure exerted by the static mud column the hydrostatic pressure is maintained in order to prevent a kick or ultimately a blow out. The mud weight is a function of both the density and the depth of the mud. This weight (mud weight) is what will determine, with conjunction with the depth, the pressure that will be exerted on the formation while drilling this experiment will be carried out using a mud balance (4 scale metal mud balance) The ranges of the scale are:
Procedures (Sample 1)
READINGS (DENSITY) PPG S.G Lb/ft3 Psi/1000ft SAMPLE 1 8.7 1.04 65455SAMPLE 2 8.81.0666460
After the experiment has been carried out, and the following results has been obtained for the experiment to determine the density we discovered that sample 1 (mixture of bentonite) our mud had a lower density than sample 2 which is a mixture of the mud and barite. This is because barite is a weighing agent that is used to increase the weight of mud, therefore the sample 2 is to have a higher density as sample 1 because of the presence of barite.
In conclusion, the mud density test is a very important test that is carried out to determine the density of mud, from this experiment we also observed that the density of sample 2 (mixture of barite bentonite and water) has a heavier density that sample 1 (mixture of bentonite and water) because of the presence of barite which acts as a weighing agent and it increses the density.
