Abstract
Systems and methods for subterranean formation testing. A method may include: lowering a formation testing tool into a subterranean formation, wherein the formation testing tool may include memory, a pump, a formation probe, at least two sample chambers, wherein the at least two sample chambers may include probes to measure pressure and temperature; extracting a fluid from the subterranean formation with the pump and the formation probe; flowing the fluid into the at least two sample chambers with the pump; storing pressure and temperature data of the fluid in the memory; and removing the at least two sample chambers from the formation testing tool.
Claims19
A method comprising:
- lowering a formation testing tool into a subterranean formation, wherein the formation testing tool comprises memory, a pump, a formation probe, at least two sample chambers, wherein the at least two sample chambers comprise probes to measure pressure and temperature and wherein the at least two sample chambers comprise a cushioned sample chamber comprising a nitrogen section and a fluid sample section, and an un-cushioned sample chamber comprising a fluid sample section;
- extracting a fluid from the subterranean formation with the pump and the formation probe;
- flowing the fluid into the at least two sample chambers with the pump;
- storing pressure and temperature data of the fluid in the memory;
- and
- removing the at least two sample chambers from the formation testing tool.
A method comprising:
- lowering a formation testing tool into a subterranean formation, wherein the formation testing tool comprises memory, a pump, a formation probe, an un-cushioned sample chamber, and a cushioned sample chamber, wherein the un-cushioned sample chamber and the cushioned sample chamber each comprise probes to measure pressure and temperature;
- wherein the cushioned sample chamber further comprises a piston;
- extracting a fluid from the subterranean formation with the pump and the formation probe;
- flowing the fluid into the un-cushioned sample chamber and the cushioned sample chamber with the pump;
- storing pressure and temperature data of the fluid in the memory;
- removing the un-cushioned sample chamber and the cushioned sample chamber from the formation testing tool;
- transporting the un-cushioned sample chamber and the cushioned sample chamber to a lab;
- determining fluid properties of the fluid at a downhole pressure and temperature;
- and
- comparing the fluid properties from the un-cushioned sample chamber to the cushioned sample chamber to provide quality control of the fluid.
A formation testing tool comprising:
- a pump;
- a formation probe;
- at least two sample chambers, wherein the at least two sample chambers comprise a cushioned sample chamber comprising a nitrogen section and a fluid sample section, and an un-cushioned sample chamber comprising a fluid sample section;
- a pressure sensor to measure pressure in the sample chamber;
- a temperature sensor to measure temperature in the sample chamber;
- and
- a memory to record measurements from the pressure sensor and the temperature sensor.
A method comprising:
- lowering a formation testing tool into a subterranean formation, wherein the formation testing tool comprises memory, a pump, a formation probe, at least two sample chambers, wherein the at least two sample chambers comprise probes to measure pressure and temperature and wherein the at least two sample chambers comprise a cushioned sample chamber comprising a nitrogen section and a fluid sample section;
- extracting a fluid from the subterranean formation with the pump and the formation probe;
- flowing the fluid into the at least two sample chambers with the pump;
- storing pressure and temperature data of the fluid in the memory;
- determining fluid properties of the fluid utilizing a pressure, volume and temperature of the nitrogen;
- and
- removing the at least two sample chambers from the formation testing tool.
