20130311096, Nov 21, 2013

Filed:

May 21, 2012

Appl. No.:

13/476658

Inventors:

Carl Thomas Greer - Houston TX, US
Rodney Hayes Neumann - The Woodlands TX, US

International Classification:

G01N 30/00
G06F 19/00
E21B 21/08

US Classification:

702 9, 175 48

Abstract:

A new approach to measuring the gases present in the drilling fluid, or “mud”, while drilling oil and gas wells and analyzing the mud at the well surface. The method replaces inconsistent legacy measurements which mix the formation gases with air arbitrarily and report inconsequential values called “units, Equivalent Methane in Air.” This method instead expresses gas values in terms of Volume of Gas Per Volume of Mud, producing values of universal meaning that everyone can standardize upon. The method further improves gas measurement by expressing gas content using the several energy values of the gases. The resulting standard is a summation measurement of the energy of all gas components present, not limited to Methane. The end result is a gas concentration value that is made universally consistent across many logs made at different times in any location or formation.

Appl. No.:

7/003353

Carl T. Greer - Houston TX

International Classification:

E21B 4700

US Classification:

73155

Abstract:

A continuously adjusted calculated annulus drilling fluid lag time while drilling oil and gas wells and analyzing the drilling mud at the well surface for formation gas, fluids and rock in order to accurately index the release of the formation gas, fluids and rock released by the drill bit with the depth at which they were released. The method obtains such analyses by using a computer and pumping pressure to accurately track the drilling mud time lag and automatically adjusts for variations in the annulus flow rate to correlate the recorded data with its originating depth.
