Patent number: 10241010Abstract: Methods and apparatus for the collection, transportation, and analysis of gas samples which may be required in various scientific, environmental, and natural resource contexts is provided. An isolating container for removing a component from a fluid sample includes a body defining a sampling chamber having a first end and a second end; a first valve assembly coupled to the first end; a reactant material positioned within the sampling chamber for reacting with the component; and a second valve assembly coupled to the second end, wherein the fluid sample enters the sampling chamber through the first valve assembly and exits through the second valve assembly.Type: GrantFiled: April 1, 2015Date of Patent: March 26, 2019Assignee: Weatherford Technology Holdings, LLCInventors: Todd M. Coleman, Corben C. Rice, Dennis D. Coleman

Patent number: 9983103Abstract: A gas sample extraction assembly for controllably accessing gas in a gas sample container includes a coupler body having a coupler bore and a coupler end for engaging the gas sample container; an upper member having an upper member bore; a biasing member disposed between the upper member and the coupler body; and a stem having a first portion coupled to the upper member bore and a second portion disposed in the coupler bore, the stem being movable relative to the coupler body between a first axial position and a second axial position, wherein the biasing member is configured to bias the stem in the first axial position.Type: GrantFiled: February 25, 2014Date of Patent: May 29, 2018Assignee: Isotech Laboratories, Inc.Inventors: Dennis D. Coleman, Todd M. Coleman

Patent number: 9321052Abstract: A container for collecting water samples to determine dissolved gas includes a flask-type pouch with a spout. A removable cap and valve install on the spout. The valve includes an adapter that fits with an O-ring or other seal inside the mouth of the spout. The valve includes a valve element, which can be a one-way, self-closing type of valve, that fits with an O-ring or other seal inside the end of the adapter. A cap of the container fits over the adapter and affixes to the spout to hold the valve on the spout. In use, the cap can be removed so that the valve element and adapter can be removed for filling the pouch. Otherwise, the cap can remain in place so filling can be performed through the valve element. A tamper-evident ring on the cap may be provided to ensure the integrity of the sample contained in the flask.Type: GrantFiled: May 16, 2014Date of Patent: April 26, 2016Assignee: Weatherford/Lamb, Inc.Inventors: Todd M. Coleman, Gavin A. Steele

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.
