... changes due to injected blend ratios during underbalanced drilling is highlighted. Using the relationship between inflow and bottomhole pressure changes, optimum wellbore lengths as well as reservoir evaluation could be achieved during underbalanced drilling. Introduction The application of underbalanced...

The intentional flow of reservoir fluids into the wellbore, caused by the drawdown gradient during underbalanced drilling, naturally prevents well damage that results from drilling fluid and solid invasion. Field data and simulation results show that this phenomenon improves the skin and well conductivity, kh...
