Filed:

Apr 30, 2004

Appl. No.:

10/836996

Inventors:

Michael Shammai - Houston TX, US
Robert Gordon - The Woodlands TX, US
Francisco Galvan Sanchez - Houston TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

G01N 23/00
E21B 49/08

US Classification:

7315228, 7315214, 7315223

Abstract:

The present invention provides a downhole sample tank and a plurality of micro sample chambers. The micro sample chambers can have at least one window for introduction of visible, near-infrared (NIR), mid-infrared (MIR) and other electromagnetic energy into the tank for samples collected in the micro sample chamber downhole from an earth boring or well bore. The window is made of sapphire or another material capable of allowing electromagnetic energy to pass through the window. The entire micro sample chamber can be made of sapphire or another material capable of allowing electromagnetic energy to pass another material enabling visual inspection or analysis of the sample inside the micro sample chamber. The micro sample chamber enables immediate testing of the sample on location at the surface to determine the quality of the sample in the main sample tank or to enable comprehensive testing of the sample.

Assignee:

International Classification:

E21B 49/08

US Classification:

166264, 166162, 7386435, 7386462

Abstract:

A method and apparatus store energy in an energy storage medium located in an energy storage chamber. As a sampling tool descends into the borehole, the energy storage medium is pressurized with hydrostatic pressure. A sample is collected in a sample chamber by pumping formation fluid into the sample chamber against hydrostatic pressure. The energy storage medium applies the energy stored in the energy storage medium to the sample through a pressure communication member. A pressure multiplier member increases the pressure applied on the sample by the energy storage medium through the pressure communication member to keep pressure on the sample. A biasing water pressure is applied to the sample at the surface so that the energy storage chamber can be removed from the sample chamber.

Abstract:

The present invention provides an apparatus and method for continuously monitoring the integrity of a pressurized well bore fluid sample collected downhole in an earth boring or well bore. The CDR continuous by measures the temperature and pressure for the down hole sample. Near infrared, mid infrared and visible light analysis is also performed on the small amount of sample to provide an on site analysis of sample properties and contamination level. The onsite analysis comprises determination of gas oil ratio, API gravity and various other parameters which can be estimated by a trained neural network or chemometric equation a flexural mechanical resonator is also provided to measure fluid density and viscosity from which additional parameters can be estimated by a trained neural network or chemometric equation. The sample tank is overpressured or supercharged to obviate adverse pressure drop or other effects of diverting a small sample to the CDR.
