Appeal No. 2003-0533
Application No. 09/511,183
an independent validation sample chamber,
having a substantially smaller capacity than
the sample chamber, that will be safer and
easier to heat and recombine separated sample
components on the surface for validating the
quality of the sample at the well site.
Independent claim 1 is drawn to a sample module for use in a
downhole tool to obtain fluid from a subsurface formation
penetrated by a wellbore, comprising, inter alia, a sample
chamber carried by the module, a validation chamber carried by
the module, with the validation chamber being smaller than the
same chamber and independently removable from the sample module.
Independent claim 13 sets forth an apparatus for obtaining
fluid from a subsurface formation penetrated by a wellbore,
comprising, inter alia, a probe assembly, a pump assembly, a
sample chamber, and a validation chamber smaller than the sample
chamber and independently removable from the apparatus.
Independent claim 22 addresses a method for obtaining fluid
from a subsurface formation penetrated by a wellbore, comprising,
inter alia, delivering a sample of formation fluid moved into an
apparatus to a sample chamber for collection therein, delivering
a representative sample of formation fluid to a validation
