  • Simulating the control of solids in drilling fluids, and application to determining the size of cuttings
    Patent number: 6665636
    Abstract: The present invention relates to a method of modelling a circuit travelled by a drilling mud during drilling, the circuit including both the well and the surface equipment, in particular solid separation devices, in which method, for each time sequence, there are calculated the mass concentration of each liquid and solid species present in the mud, the total flow rate, and the grain size distribution of each solid species downstream from each item of equipment. The invention also provides inversion of the above method to estimate the size of the cuttings on the basis of the measured efficiency of solid separation devices.
