    摘要: Methods and system for incorporating downhole and surface data with models and adjustment algorithms to back allocate flow rates of commingled zones. The models include fluid flow in the reservoir and wellbore, pressure drop across a choke, and fluid flow in the well completion. The models are coupled with an algorithm for comparing the results from the individual commingled zones to the total cumulative commingled volume and adjusting at least one predicted rate so that they match the measured flow rate over a specified time period. One method utilizes a reassignment factor for the adjustment of the predicted rates. These comparisons and allocation adjustments can be accomplished even when the frequency of the commingled flow rate and cumulative measurements, and the frequency of the predicted rates from the model differ from each other and the specified time period.

    摘要: A method of completing a well involving remediating a condition of screen-out that has taken place along a zone of interest. The method includes forming a wellbore, and lining at least a lower portion of the wellbore with a string of production casing and placing a valve along the production casing, wherein the valve creates a removable barrier to fluid flow within the bore. The barrier is removed by moving the valve in the event of a screen-out. This overcomes the barrier to fluid flow, thereby exposing ports along the production casing to the subsurface formation at or below the valve. Additional pumping takes place to pump the slurry through the exposed ports, thereby remediating the condition of screen-out.
