Mud Products Inventory Form

In order to mix the mud for the drilling of a well it is necessary to maintain sufficient stock levels at the rigsite. It is vital that stock levels are regularly monitoring through frequent inventory…

Downhole Density Measurements

Mud density will decrease with increasing temperature, and increase with increasing pressure. Theoretical models similar to those mentioned in SPE Paper 11118 predict that temperature is the major…

This article presents some tips for running drilling fluid systems.

PV and YP

For optimum hydraulic parameters the values of PV and YP should be as low as hole cleaning efficiency and suspension of…

Hydraulics Optimization - Hole Cleaning

To optimize hydraulics and achieve sufficent hole cleaning the following guidelines should be adhered to:
