Oil Soluble Plugging Drilling Fluid is a superior plugging agent used to bridge and seal permeable formations in oil base mud systems. It is used to reduce the HTHP FL in the oil based mud. It helps to promote emulsification of the reverse emulsion and improve emulsion's stability, particularly used in deep wells with high temperature. Bridging and sealing permeable formations reduces the differential-pressure sticking tendencies which can cause high torque and drag or stuck pipe. The product is particularly useful for preventing differentially-stuck pipe when drilling depleted zones where high differential pressures exist. For added flexibility, RXSOL fiber is available in fine (original), medium and coarse grades so that the optimum particle size can be selected to bridge the pores and pore throats of permeable formations. RXSOL fiber additions have minimal effect on mud properties.

Application

RXSOL Oil Soluble  Plugging  which can be used for leakage control by  plugging in drilling, completion and workover, especially in sandstone formation of high permeability. The grain size and softening point can be selected in the period of manufacturing according to the formation pore and temperature. Generally is added into the killing fluid to play a role of anti-leakage. 

• RXSOL Oil Soluble Plugging is a superior bridging agent, field-proven to be highly effective when drilling high-permeability/ high-porosity zones with high differential pressures. Each grind size has a specially selected particle size distribution optimized to seal a wide range of formations.
   
• RXSOL Oil Soluble Plugging is designed to bridge and seal permeable formations, reducing the possibility of stuck pipe, controlling lost circulation and providing filtration control. It is compatible with water-, oil- and synthetic-base mud systems.
