Abstract
An apparatus includes a sample compartment. The apparatus further includes an inlet port through which the sampled reservoir fluid may be introduced into the sample compartment. The apparatus further includes a concentrating object that can be placed within the sample compartment. The concentrating object includes an outer surface and an inner surface recessed from the outer surface. The inner surface is receptive to adsorbing the selected portion of the sampled reservoir fluid.

An apparatus for acquiring and concentrating a selected portion of a sampled reservoir fluid, the apparatus comprising:
- a sample compartment;
- an inlet port through which the sampled reservoir fluid may be introduced into the sample compartment;
- a concentrating object that can be placed within the sample compartment, the concentrating object comprising:
- an outer surface;
- and
- an inner surface recessed from the outer surface, the inner surface being receptive to adsorbing the selected portion of the sampled reservoir fluid;
- a member to hold the concentrating object in place in the sample compartment;
- the member to release the concentrating object so that it can move within the sample compartment as the sample compartment is filled.
A method for acquiring and concentrating a selected portion of a sampled reservoir fluid, the method comprising:
- inserting a concentrating object into a sample compartment;
- securing the concentrating object in a secured position in the sample compartment;
- inserting the sample compartment into a downhole tool;
- lowering the downhole tool into a well bore;
- receiving a sample of fluid from the reservoir into the sample compartment, the reservoir having a reservoir temperature and a reservoir pressure;
- releasing the concentrating object from the secured position so that it can move within the sample compartment as the sample compartment receives the sample of fluid from the reservoir;
- retrieving the downhole tool from the well bore;
- removing the sample compartment from the downhole tool;
- raising the sample compartment to substantially the reservoir temperature;
- transferring the sample from the sample compartment;
- removing the concentrating object from the sample compartment;
- heating the concentrating object to desorb any of the selected portion that the concentrating object adsorbed from the sample;
- passing an inert gas over the heated concentrating object;
- and
- measuring the concentration of the selected portion.
An apparatus for acquiring and concentrating a selected portion of a sampled reservoir fluid, the apparatus comprising:
- a probe to extend and engage a formation exposed in a well bore;
- a pump coupled to the probe for pumping fluid from the formation;
- a sample compartment coupled to the pump to receive at least a portion of the fluid pumped from the formation through the probe;
- a concentrating object placed within the sample compartment, the concentrating object comprising:
- an outer surface;
- and
- an inner surface recessed from the outer surface, the inner surface being receptive to adsorbing the selected portion of the sampled reservoir fluid;
- a member to hold the concentrating object in place in the sample compartment;
- the member to release the concentrating object so that it can move within the sample compartment as the sample compartment is filled.
