Claim 10:
11. A method for measuring an asphaltene precipitation comprising:
disposing a fluid sampling tool into a wellbore at a first depth, wherein the fluid sampling tool comprises:
a probe section comprising:
one or more probes that are extendable from and attached to the probe section;
at least two stabilizers that are extendable from and attached to the probe section; and
a housing disposed in the probe section that includes a bi directional piston pump of 100 cc of capacity and a capability to operate up to 20000 psi below hydrostatic pressure;

pressing the one or more probes into a surface of the wellbore;
drawing a reservoir fluid from the wellbore through the one or more probes;
placing the reservoir fluid into the housing;
isolating the housing of the fluid sampling tool with at least three shut in valves, wherein the isolated housing has at least one pressure gauge;
depressurizing the housing with the bi directional piston pump; and
measuring the asphaltene precipitation of the reservoir fluid within the housing.
