Popis: Summary Two key benefits of downhole-gauge (DHG)-data analysis are identifying and minimizing the root causes of any failures that might occur during gravel packing and calibrating or verifying friction-pressure data for gravel-placement simulations. Although downhole pressure and temperature gauges are used often in openhole gravel packing, and expertise in analyzing the data certainly exists in companies that routinely use DHGs, to our knowledge, there is no publication that comprehensively discusses the method of analysis. DHG-data analysis, in general, requires more information than the gauge data themselves. This includes logs, wellbore schematic, pumping schedule, fluid properties, return-flow measurements, daily rig reports, and data relevant to displacements. The objective of this paper is to provide guidelines for DHG-data analysis to completion engineers, who are not routinely involved and thus are not experts in such analysis, by detailing the factors that must be kept in mind, offering a method, and demonstrating this method with several examples.
