... for the ESS well in the F1 field. Another aspect of the different completions is the variation in friction pressure between completion types such as ESS screens and EGP. The friction pressures in an ESS completion are lower than a typical EGP, standalone screen or slotted liner completion. This gives a very...

... to choke back the flow at the heel. This in effect chokes back production and it is still difficult to achieve the correct inflow without downhole flow and pressure measurements. After water breakthrough, options involve downhole flow control and water shut off treatments. egp 3 egp production...
