Patent number: 10215737Abstract: A method for preparing a sample for analysis includes separating a gas sample into at least one component sample in a separation unit. The output of the at least one component sample from the separation unit is detected, for example, using a thermal conductivity detector. A hydrocarbon in the component sample is combusted in a combustion unit to generate a combustion product. The at least one component sample is collected in a sample collector and supplied to an analysis unit. In some embodiments, the analysis unit may be used to determine an isotopic ratio of the at least one component sample.Type: GrantFiled: April 12, 2016Date of Patent: February 26, 2019Assignee: WEATHERFORD SWITZERLAND TRADING AND DEVELOPMENT GMBHInventors: Dennis D. Coleman, John Boettcher, Gavin Atlas Steele, IV

Patent number: 9146224Abstract: A canister for measuring the natural gas content of rock cores which (1) has an inner core-containment bag made of non-permeable plastic which can be flash evacuated, collapsing around the core and thus minimizing the amount of air present and improving the quality of the gas analyses and (2) which prevents the released gas from reacting with the outer canister. A procedure for using gas-sampling bags to periodically collect the gas released from the core so that (1) the volume of released gas can be measured at a later date using more convenient and precise laboratory methods, (2) the gas can be readily transported and stored, and (3) the gas can be easily submitted for analysis.Type: GrantFiled: September 3, 2013Date of Patent: September 29, 2015Assignee: Isotech Laboratories, Inc.Inventors: Dennis D.

Patent number: 7223602Abstract: The invention provides a method of online and on-site tracer generation for tagging natural gas stored in underground storage fields wherein feedstock is drawn from a feedstock source. The feedstock undergoes initial analysis to determine hydrocarbon levels. The feedstock then undergoes reaction to produce tracers such as ethylene, propylene, acetylene hydrogen and carbon monoxide. The feedstock is then analyzed to determine post reaction tracer concentration. The feedstock including generated tracers is then introduced back into the feedstock stream. Tracer levels in the pre-reaction or initial analysis of feedstock are compared with tracer levels in the post-reaction feedstock and the rate of flow of feedstock through the system is adjusted to achieve a predetermined level of tracer concentration. The level of tracer concentration will then be used to identify the particular natural gas charge in a storage field.Type: GrantFiled: September 4, 2002Date of Patent: May 29, 2007Inventors: Dennis D.
