US Patent:

6912898, Jul 5, 2005
Filed:

Jul 8, 2003
Appl. No.:

10/614850
Inventors:

Christopher Jones - Houston TX, US
Jon Burger - Houston TX, US
Patrick Jacobs - Houston TX, US
Richard J. Drozd - Houston TX, US
Assignee:

Halliburton Energy Services, Inc. - Houston TX
International Classification:

E21B049/00
US Classification:

7315211
Abstract:

A method for measuring the infiltration of coring fluid into a core sample taken from a formation comprises a) providing a coring fluid containing cesium in a first concentration, b) using the coring fluid and a coring means to generate the core sample, c) determining the concentration of cesium present in the core sample; and d) comparing the core sample cesium concentration to the first concentration. A further preferred step comprises using the comparison in step d) to calculate the degree of infiltration of the coring fluid into the core sample.

US Patent:

6967322, Nov 22, 2005
Filed:

Mar 1, 2004
Appl. No.:

10/790287
Inventors:

Christopher Jones - Houston TX, US
Zvi Sofer - Houston TX, US
Richard J. Drozd - Katy TX, US
Assignee:

Halliburton Energy Services, Inc. - Houston TX
International Classification:

G01N021/35
US Classification:

2502691, 250343, 250345
Abstract:

Method and apparatus for providing real-time data indicative of the isotopic composition of formation fluids during drilling. The method includes the steps of: (a) providing a reference fluid having a known isotopic composition in a reference cell; (b) capturing a sample of formation; (c) providing at least one laser beam; (e) passing a beam through the reference fluid, measuring the reference-measurement beam before and after it passes through the reference fluid; (f) and passing a beam through the sample, measuring the beam before and after it passes through the sample, and calculating a first isotope concentration from those measurements. The measurements can provide information relating to the carbon isotopic composition of individual compounds in hydrocarbon gas mixtures, with the individual compounds including methane, ethane, propane, iso- or normal butane, or iso- or normal pentane.

US Patent:

7438128, Oct 21, 2008
Filed:

May 4, 2005
Appl. No.:

11/122159
Inventors:

Richard J. Drozd - Katy TX, US
Louis W. Elrod - Houston TX, US
Patrick Jacobs - Shenandoah TX, US
Assignee:

Halliburton Energy Services, Inc. - Duncan OK
International Classification:

E21B 47/00
E21B 47/10
US Classification:

1662541, 16625007, 166264, 7315219, 7315222, 7315223, 7315227, 175 50, 702 9
Abstract:

A method for identifying annular gas sources in a wellbore is disclosed. In one embodiment, the method comprises providing a set of parameters, wherein the set of parameters corresponds to depths in the wellbore. In addition, the method comprises analyzing annular gas in the wellbore to provide isotopic data of the annular gas. The method further comprises correlating the isotopic data to the set of parameters to identify the annular gas source.
