Pressure-corrected density of a fluid

A method of determining a density of a fluid in a formation, the method comprising:

• measuring a first fluid density value of a fluid sample at a first pressure;
• altering the first pressure to a second pressure different than the first pressure;
• measuring a second fluid density value of the fluid sample at the second pressure;
• and
• at least one of extrapolating and interpolating a third fluid density value at a third pressure based, at least in part, on the first fluid density value at the first pressure and the second fluid density value at the second pressure;
• wherein the third pressure is different than the first pressure and the second pressure.

An apparatus for determining a density of a fluid in a formation, the apparatus comprising:

• a fluid chamber adapted to at least temporarily hold a fluid sample;
• one or more pressure regulator to regulate a pressure applied to the fluid sample between a first pressure and a second pressure, the first pressure being different than the second pressure;
• one or more pressure gauge to measure the pressure applied to the fluid sample;
• one or more density sensor to measure the density of the fluid sample at the first pressure and the second pressure;
• and
• one or more signal processor to determine a density of the fluid sample at a third pressure via at least one of an extrapolation technique and an interpolation technique, the third pressure being different than the first pressure and the second pressure.
