The water rates are approximately double those achieved when compared to the same stage of pressure drawdown
for the previous pilot configuration of Glenaras 10L and 12L.
Portland oil has continued to be produced at over 220 barrels a day, through a modest pressure drawdown
The flow rate was restricted with limited pressure drawdown
and each zone was shut-in for an extended period to establish a significant radius of investigation for each test, and neither gave any indication of depletion or significant barriers within the reservoir.
"During the fourth quarter we began testing pressure management techniques designed to maximize oil production by managing bottom hole pressure drawdown
rate," Maranto said.
The most important stages are mainly the pressure drawdown
stage and pressure buildup stage.
A change in initial pressure condition and bottom-hole pressure is applied in order to consider the effect of fluid compressibility while the pressure drawdown
is the same as previous model.
The general form of material balance deconvolution is provided for the pressure drawdown
case in terms of the material balance time function and the rate-normalized pressure drop function.
Or, program the controller to pull the screw back a fraction of an inch before screw rotation to accomplish the same pressure drawdown
. Then start screw rotate.
The high flow rates and relatively low pressure drawdown
of this well demonstrate excellent productivity, and the data confirms we are connected to a large reservoir.
These tools are designed to respond to formation-behavior-induced mechanical disturbance, such as an applied stress or a pressure drawdown
in the wellbore.
The Pilot is performing strongly and demonstrating excellent water rates given this early stage of pressure drawdown
, with the five wells already flowing at water rates in excess of 4,200 BWPD in aggregate.
