Abstract
Apparatus and methods for collecting a downhole sample are provided. The method may include introducing a flowable sealant to a borehole wall portion, modifying a formation system mobility using the flowable sealant, and receiving the downhole sample using a sample receiving port positioned proximate the borehole wall portion. An apparatus includes a formation sampling member having a sample receiving port for receiving the downhole sample, and an inhibitor that includes one or more of an activator and an injector.
Claims23
A method for collecting a downhole sample comprising:
- introducing a flowable sealant to a borehole wall portion through a sample receiving port;
- modifying a formation system mobility using the flowable sealant;
- and
- receiving the downhole sample using the sample receiving port positioned proximate the borehole wall portion.
A method for collecting a downhole sample comprising:
- contacting a borehole wall portion using a sampling tool that includes a sample receiving port for receiving the downhole sample;
- introducing a flowable sealant through the sample receiving port to a borehole wall portion proximate the sample receiving port;
- and
- receiving the downhole sample by flowing the downhole sample through the sample receiving port.
An apparatus for collecting a downhole sample comprising:
- a formation sampling member having a sample receiving port for receiving the downhole sample;
- and
- an inhibitor configured to introduce a flowable sealant to a borehole wall portion, the inhibitor including the sample receiving port for flowing the flowable sealant therethrough and one or more of an activator and an injector.
