Abstract
A method and apparatus for sampling fluids from an undersea wellbore comprising a self-propelled underwater vehicle and a collection and storage device; so that samples may be recovered directly from the wellbore and subsequently analyzed to determine the characteristics of the oil produced from separate wells.
Claims27
A method for sampling a fluid produced from a wellbore, the method comprising:
- providing a vehicle having a drive means for moving the vehicle, a collecting device for collecting a sample of fluid, and a storage facility for the collected sample of fluid, said collecting device and said storage facility being connected to said vehicle;
- using the collecting device to collect a sample of the fluid from a subsea structure at a first location;
- storing the sample in said storage facility of said vehicle;
- and
- carrying the sample to a second location which is different from said first location.
A sampling device for collecting samples of fluid produced from a subsea wellbore, the sampling device having a drive means for moving the sampling device, a collecting device for collecting a sample of fluid and a storage container for holding the collected fluid, wherein the drive means comprises a remotely operated vehicle.
A method for sampling a fluid produced from a plurality of wellbores, comprising the steps of:
- using an underwater vehicle to receive a plurality of fluid samples from respective ones of said plurality of wellbores and to store said plurality of fluid samples in a plurality of respective containers;
- transporting said plurality of containers to an operating station for testing.
A system for sampling wellbore-produced fluids, said system comprising:
- a plurality of wellbores located underwater;
- an operating station, which is at a location separate from said plurality of wellbores, said operating station having a capability to receive and test samples of fluid;
- a collection vehicle which is configured to collect separate samples of fluid from one of said plurality of wellbores and transport said separate samples to said operating station.
