Title: Method for spectrometrically measuring isotopic gas and apparatus thereof
Inventor: IKEGAMI EIJI
IPC: G01N21/35
Filed: 1996-10-02
Abstract: A correction curve is prepared by plotting 12CO2 concentrations and 13CO2/12CO2 concentration ratios which are determined on the basis of a calibration curve and 13CO2 and 12CO2 absorbances of gaseous samples having the same 13O2/12CO2 concentration ratio but known different 12CO2 concentrations. A gaseous test sample containing 13CO2 and 12CO2 as component gases is introduced into a cell, and spectrometrically measured. A 12CO2 concentration of the gaseous test sample is determined by way of the spectrometric measurement. A concentration ratio correction value is obtained on the basis of the correction curve and the 12CO2 concentration of the gaseous test sample thus determined. A measured 13CO2/12CO2 concentration ratio is divided by the concentration ratio correction value thus obtained for correction of the 13CO2/12CO2 concentration ratio. Thus, the measurement accuracy of the concentration ratios of the component gases can be improved.

Title: Downhole fluid separation system
Inventor: BOWERS BILL E
IPC: B01D17/12
Filed: 1997-07-16
Abstract: A downhole fluid separation system comprises a fluid separator having a fluid inlet, a first fluid outlet, and a second fluid outlet, with a sensing device for sensing at least one parameter of a first component of a fluid mixture introduced into the fluid inlet of the fluid separator. The ratio of the first component to a second component of the fluid mixture is adjusted as such fluid mixture is introduced into the fluid inlet of the fluid separator in response to a signal provided by the sensing means. By adjusting the component ratio before the fluid is introduced into the fluid separator in response to a signal from a downhole sensing device, acceptable separation efficiency can be achieved over a broad range of fluid component ratios for a given fluid separator.
