Paper presented at the SPE Latin American and Caribbean Petroleum Engineering Conference, July 27–31, 2020
Paper Number: SPE-199075-MS
... Cementing in two stages was recommended as an option to isolate the lower section exhibiting abnormal pressure first and then perform the second stage cementing with new conditions to isolate the upper section having lost circulation. Finally, the operator decided to use a conventional cement...

... to Pdp {500) plus Pr {1,000), or 1,500 psi. Since tne mud weight will not change during the first circulation, utilizing the driller's method, the 11 500 psi will also be the final circulating pressure {Fcp) Thus, under initial circulation conditions, the well can be controlled without exceeding...

..., the Drillpipe Pressure should be maintained at the Final Circulating Pressure (FCP) for the rest of the circulation. However, during this period, the Final Circulating Pressure gives a more stable value thus it is better to go back to the traditional method and control the choke just by maintaining the FCP...

... horizontal kill sheet at a circulation rate of 40 spm. In the case of vertical step-down (case 1) it is assumed that the final circulating pressure (FCP) will be achieved when the heavy mud filled the drill string and reached the bit after 2,614 strokes (step 2-b). The average shut-in drill pipe pressure...

... and the bit pressure drop all increase resulting in a decrease in circulating drillpipe pressure. This Final Circulating Pressure is calculated by multiplying the kill rate pressure by the ratio of the kill mud density to the old mud density. Since the kill rate pressure is the pressure loss in the entire...
