Abstract
A method for determining the downhole flow regime in a horizontal well borehole traversing a subterranean formation. A first gas holdup value within the borehole is measured using a fluid density tool. A second gas holdup value within the borehole is measured using a fullbore gas-holdup tool. The downhole flow regime is then determined as a function of the first gas holdup value and the second gas holdup value. A downhole flow regime comprised of dispersed bubble flow is indicated where the first gas holdup value is approximately equal to the second gas holdup value. A downhole flow regime comprised of annular flow is indicated where the first gas holdup value is substantially greater than the second gas holdup value and the velocity of the gas phase is substantially greater than the liquid phase. A downhole flow regime comprised of stratified flow is indicated where the first gas holdup value is less than or greater than the second gas holdup value.
