SINGLE POINT AND FIBER OPTIC TEMPERATURE MEASUREMENT FOR CORRECTION OF A GAS COLUMN WEIGHT IN A WELL

摘要

Fluid column weight correction using discrete point and fiber optic temperature measurement. A method for determining pressure at a distal end of a fluid column in a well includes the steps of: dividing the fluid column into multiple segments; determining a temperature of each segment; and determining a pressure and density for each segment. Another method includes the steps of : determining the temperature of each segment by measuring a temperature in the well near a proximal end of the fluid column, and using the measured temperature in conjunction with a thermal wellbore model to generate a temperature profile of the fluid column. Another method includes the steps of: causing a pressure change in the fluid column; recording multiple pressure measurements during the pressure change; and generating a temperature profile of the fluid column for each of the pressure measurements.
