Patent ID: 8813554

Claim:
A method of estimating one or more volumes of one or more components of a fluid in a sample chamber of a downhole tool, the method comprising: obtaining a sample chamber volume measurement; obtaining a flowline volume measurement; obtaining a supplemental volume measurement; drawing the fluid into the sample chamber until the sample chamber is substantially full; measuring a characteristic of the fluid in the sample chamber at a first time to obtain a first characteristic measurement; adding a supplemental volume corresponding to the supplemental volume measurement to over-pressurize the sample chamber after measuring the characteristic at the first time; measuring the characteristic of the fluid in the sample chamber at a second time to obtain a second characteristic measurement, the second time being after the sample chamber is over-pressurized; and calculating a first volume of a first component of the one or more components of the fluid based on the first characteristic measurement, the second characteristic measurement, the sample chamber volume measurement, the flowline volume measurement and the supplemental volume measurement.
