Automatic evaluation and adjustment of drilling fluid properties and compositions during MPD operations and its cost-benefit analysis

Master's thesis in Industrial economicsIn this thesis a differential pressure system "Dual DP", originated at the University of Stavanger, is employed to test differential pressure of a fluid flow. From this, several properties of the fluid can be calculated including the density and viscosity. In addition, the Fann® 35 rheometer’s diversity gets a review, to see if there are ways to get more accurate results of the dial readings. Several spring sensitivities are applied
