A sample tank for receiving and storing sampled connate fluid from a subterranean geological formation. The sample tank includes a piston coaxially disposed within the tank. The piston can be disposed close to the end of the tank where the sampled fluid is introduced into the tank and urged along the length of the tank as sampled fluid is added to the tank. The piston includes an agitator for mixing the fluid and keeping particulates suspended within the fluid. The agitator includes a magnetic member, and is rotated by applying a varying electromagnetic field to the member.

Magnetic stirrer

The present invention provides a sample tank having a window for introduction of electromagnetic energy into the sample tank for analyzing a formation fluid sample down hole or at the surface without disturbing the sample. Near infrared, mid infrared and visible light analysis is performed on the sample to provide a downhole in situ or surface 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 pressurized to obviate adverse pressure drop or other effects of diverting a small sample.

Method and apparatus for an advanced optical analyzer

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.
