CALCULATING THE FLOW RATE OF A HORIZONTAL OPEN HOLE WELL

Based on literature survey on formulas for calculating flow rates, the authors conclude that the problem of calculating the flow rates of horizontal wells currently remains relevant. However, the emphasis is on reproducing the geometry of streamlines in gas flow as accurately as possible and insuffi...
