Drilling Fluid: Testing Testing and mud cleaning may have put into a section of it own. Drilling fluids  properties are continually  being altered throughout the drilling process. Monitoring these changes allows for the proper corrective action. Formation fluids, solids or gases often invade the well bore and alter the Rheological properties or chemical balance of the system. Other individual measurements of chemical properties are also necessary to monitor a well in its completion and production phases to prevent corrosion or degradation of the well’s producing ability. Rheological properties, fluid loss characteristics, and density are perhaps three of the most important drilling fluid properties.  The derrick man will constantly monitor two of the most important fluid property. The weight and the viscosity both will give an early warning signal of pending changes. Other checks he will possibly do are the sand content and the PH  all are within the scope of the derrick man all are easy to do, taking very little time. By keeping a time record it will soon become apparent there is a change taking place. The derrick man will often be the first to see a change. As the whether he understand what is happening is a different story. A good drilling fluid engineer will work with the derrick man training him to recognize potential problems. Many potential hazards can be sorted out if recognized in the early stages Many company manufacture testing equipment under many names however as with all things involved within the drilling industry they all do the same job. Due to the lack of responses from manufacture the equipment being explained will generalize. Any company involve in the manufacturing of such testing equipment and would like to see their name, equipment and company reputation up in lights, viewed by 1000's of Mud engineer, students, potential work force and the professional drilling community world wide.
