The usage of Pneumatic fluid in drilling and enhanced oil recovery

One methods of drilling in some fields, the use of fluids is Pneumatic. Drilling conditions such as pressure, flow, torque and foam When editing the drill string out of the well has a special role to control problems. The main reason for choosing this type of fluid, increasing drilling speed and reducing the final cost, reduce formation damage during drilling and lost. And in enhanced oil recovery, due to the high mobility ratio between oil and gas in the reservoir, flooding the gas has a low swipe efficiency. Flowing foam in porous media trapped the gas or gas stream for the continuous or discontinuous phase. In this paper, how to monitor and verify the flow of gas drilling and surface active agent are discussed in porous media and laboratory and field results obtained from flooding with foam mentioned, Which is a useful resource for engineers and researchers interested in flowing foam in porous media. And provides the area for waterflood projects with foam
