Testing in a Flow Loop Abstract The equivalent circulation density reduction tool (ECDRT) is designed to counter the increased fluid pressure in the annulus caused by friction loss and cuttings load by reducing...

... history of fluid circulation and drilling operations can be captured. A chart has been provided in Figure 9 which may be used if a rough estimate of likely supercharging levels is required. The simulation results show that high drilling fluid circulation rates and/or narrow BHA-formation clearances...

... supercharging effect. These laboratory experiments suggest that the filtration rate depends on the mudcake shear stress, which equates essentially, for a given bottom-hole assembly (BHA) and wellbore configuration, to the circulation rate; the properties of the mud and hence the mud type, its rheology...
