Patent ID: 8146660

Claim:
A method of collecting a single phase fluid sample from a well extending below a surface of the earth, the method comprising: running a fluid sampler into the well on a coiled tubing string by deploying a continuous pipe string from a coiled tubing reel, the fluid sampler including a longitudinally extending central passageway defining a charging chamber, a metering fluid chamber and a sample fluid chamber; actuating the fluid sampler to establish fluid communication between the sample fluid chamber and an exterior of the fluid sampler; obtaining a fluid sample from the well in the sample fluid chamber at a controlled rate by metering a fluid through a restriction in the metering fluid chamber; increasing fluid pressure in the coiled tubing string using a pressure source located above the surface of the earth to pressurize fluid in the charging chamber; pressurizing the fluid sample in response to increasing fluid pressure in the charging chamber; and retrieving the coiled tubing and the fluid sampler containing the fluid sample from the well.
