Drilling fluid types PetroWiki

In addition to being safe and economical for the application, a DIF should be compatible with the reservoir’s native fluids to avoid causing precipitation of salts or production of emulsions. A suitable nondamaging fluid should establish a filter cake on the face of the formation, but should not penetrate too far into the formation pore pattern.

Laboratory Development and Application of a Synthetic Oil ...

A successful OB/SBM filter cake treatment must break the mud's interfacial rheological properties, act as a demulsifier to break the waterinoil emulsion, and break the filter cake's bond with the wellbore wall. A synthetic oil/surfactantbased fluid system has been developed to cleanup OB and SB mud filter cakes.

Mud is designed to deposit thin, low permeability filter cake to limit the invasion. Problems occur if a thick filter cake is formed; tight hole conditions, poor log quality, stuck pipe, lost circulation and formation damage. In highly permeable formations with large bore throats, whole mud may invade the formation, depending on mud solids size;
