Abstract
A system and method facilitates the analysis and sampling of well fluid. A sampling and data collection device is used to detect well fluid properties in situ at a flowline installation. In an exemplary embodiment, the sampling and data collection device comprises a sample collection system having a probe adapted to selectively insert into and selectively retract from the flowline to collect a fluid sample, and a sensor system to determine PVT data in situ at the location where the probe is inserted into the flowline.
Claims24
A subsea system for collecting fluid samples and data, comprising:
- a sampling and data collection device that may be coupled to a flowline at a flowline installation, the sampling and data collection device comprising:
- a sample collection system having a probe adapted to selectively insert into and selectively retract from a flowline to collect a fluid sample;
- and
- a sensor system to determine pressure/volume/temperature (PVT) data in situ at the location of the flowline installation where the probe is inserted into the flowline.
A method of collecting information on fluids in a fluid flowline at a subsea location, comprising:
- engaging a sampling and data collection device with a flowline at a desired flowline location wherein the sampling and data collection device is capable of selectively inserting a probe into and selectively retracting the probe from the flowline;
- determining PVT properties of a flowline fluid in situ at the desired flowline location via the sampling and data collection device;
- and
- obtaining a flowline fluid sample at the desired flowline location via the sampling and data collection device.
A system for collecting fluid samples and data, comprising:
- a subsea sampling and data collection device coupleable to a subsea flowline, the subsea sampling and data collection device comprising:
- a probe assembly selectively extendable into contact with a flowline fluid within the flowline;
- an enrichment and PVT assembly to enrich a flowline fluid and to determine PVT properties of the flowline fluid in situ;
- and
- a sample collection assembly to collect a sample of flowline fluid for subsequent analysis.
A method, comprising:
- moving a sampling and data collection device to a subsea location proximate a flowline;
- inserting a probe of the sampling and data collection device into the flowline for exposure to a fluid flowing in the flowline;
- determining a property of the fluid in situ;
- and
- withdrawing a sample of the fluid from the flowline for further analysis.
