Drilling Mud density or specific gravity is the most significant measurement required and no reliable visual estimate exists. The mud density or specific gravity must be accurately measured in order to successfully drill a well hole. The most accurate measurement of mud density is made by using the Mud Balance. Viscosity is the resistance to flow offered by a fluid. The term is loosely applied as the flow properties of drilling mud. The relative viscosity‚ or the cuttings carrying ability of the

Mud weight otherwise known as drilling fluid density is a very important property of the drilling fluid which must be determined regularly during the drilling process. It is defined as the weight per unit volume of the drilling fluid or drilling mud usually expressed in units of g/cm3 or more conveniently lb/gal. Drilling fluid density or mud weight must be measured at regular intervals of the drilling process because as different formations are encountered during the drilling process‚ different

Through common practise of Centrifugal pump operating characteristics is it possible to determine the optimum conditions of particular conditions. The results of typical characteristics are expressed on this work in terms of pump discharge pressure‚ pump efficiency‚ and power demand at various pump speeds of verses pump discharge.

Mud volcanoes at Berca The mud volcanoes are situated within the area of Berca village‚ Buzau county‚ on the left bank of the Berca river. They develop in the Berca depression in several places‚ known by such names as (from south to north): “La Fierbatori”‚ “Paclele Mari”‚ “Paclele Mici”‚ “Beciu”. Access road is the Buzau-Brasov highway; at a crossroads in Satuc (a small town situated 20 km far from Buzau‚ which can be also reached by railroad) ‚ a modernized byroad leads afer 2 km to the village

Reliability Issues – Centrifugal Slurry Pumps Introduction Pumps were probably the first machine ever developed‚ and are now the second most common machine in use around the world‚ out-numbered only by the electric motor. The very earliest type of pump is now known as a water wheel‚ Persian wheel or “noria”‚ consisting of a wheel of buckets that rotates to pick up water from a stream and dump it into a trough. Another early pump was the “Archimedean screw”‚ similar to the modern screw conveyor
