Sand Content - Mud Testing

This is a simple test designed to measure the level of particles in the mud of greater that 200 mesh or 75 microns.

Mud additives are generally of smaller particle size, unless specialised materials…

Alkalinity (Pf, Mf & Pm) – Water Based Mud Testing

Test to determine nature and source of alkalinity in the mud and give an indication of mud condition. Correct interpretation of the results will highlight Carbonate / Bicarbonate contamination of mud…

API Fluid Loss - Water Based Mud Testing

API Fluid Loss - Water Based Mud Testing

The API fluid loss test is used only with Water Based Muds. The test is used to determine the static filtration characteristics of the mud and the need for treatment with fluid loss additives.

Fluid…

High Temperature / High Pressure Test (HTHP) - Mud Testing

The HTHP test is used mainly with Oil Based Mud although it may be used with water based mud under certain circumstances such as in high temperature wells or wells which exhibit a high risk of…

Solids Content - Mud Testing

Important test for determination of the drilled solids content of the mud and therefore for identification of requirements for dilution and / or changes to solids removal equipment set-up.

In the…

Total Hardness – Water Based Mud Testing

The total hardness test gives an indication of the level of soluble Calcium and Magnesium ions present in the mud.

Such ions are considered detrimental since, under conditions of high pH (>11.5),…

Calcium Hardness – Water Based Mud Testing

The Calcium test gives an indication of the level of soluble Calcium ions present in the mud.

Such ions are considered detrimental since, under conditions of high pH (>11.5), they may render…

Mud Gradient - Mud Testing

Mud weight is of the utmost importance to the safety of the drilling operation. The mud gradient must be controlled at the programmed value or at the value determined by the Drilling Supervisor, to…

Methylene Blue Test (MBT) – Water Based Mud Testing

The MBT is a rather crude chromatographic measure of the active clay content in water based muds. The MBT value must be controlled below the maximum value specified in the drilling fluids programme.…

Chlorides – Water Based Mud Testing

This test may be used for determination of Chloride content in both fresh and salt water muds.

The Chloride level must be maintained at the level specified in the drilling fluids programme.

Reporting…

Funnel Viscosity - Mud Testing

The main use of this test is to indicate trends, and signal changes, in fluid viscosity during the drilling operation.Funnel viscosity values are dependent both on fluid type and temperature,…

Mud Testing

A system of good laboratory practices and housekeeping shall be adopted to ensure accurate determination of mud chemistry and that safety is maintained.

All glassware shall be kept clean and washed…

Rheology - Mud Testing

Rheology is a fundamental mud property determining circulating pressures, suspension capabilities and carrying capacity. It must be checked regularly and controlled very carefully to ensure it is…

pH – Water Based Mud Testing

pH control is important with all water based mud systems to ensure proper functioning of chemical additives and to limit the potential for corrosion.

pH must be maintained within the range specified…
