Abstract

Systems and methods for collecting samples of production fluid from a wellbore are disclosed. In one example, a method for collecting samples of production fluid from a wellbore includes providing a fluid collector configured to selectively divert production fluid from a production flow line downstream of the wellbore to at least one sample container, and a controller configured to communicate with a computing device located remote from the fluid collector, and instructing the fluid collector to divert samples of production fluid to the at least one sample container according to a first sample collection schedule. The method also includes, during the first sample collection schedule, instructing the fluid collector, via the computing device located remote from the fluid collector, to divert samples of production fluid to the at least one sample container according to a second sample collection schedule.

Dependent claims

A method for collecting samples of production fluid from a wellbore, the method comprising:

providing a fluid collector configured to selectively divert the production fluid from a production flow line downstream of the wellbore to at least one of a plurality of sample containers on a carousel, and a controller comprising a processor, a memory, and a communication module configured to communicate with a computing device located remote from the fluid collector;
instructing the fluid collector to divert multiple samples of the production fluid to at least one of the sample containers according to a first sample collection schedule;
during the first sample collection schedule, instructing the fluid collector, via the computing device located remote from the fluid collector, to divert multiple samples of the production fluid to at least another one of the sample containers on the carousel, and changing the first sample collection schedule to a second sample collection schedule, the second sample collection schedule being different than the first collection schedule;
and
collecting the sample containers from the carousel for analysis.

providing a fluid collector configured to selectively divert the production fluid from a production flow line downstream of the wellbore to at least one of a plurality of sample containers on a carousel, and a controller comprising a processor, a memory, and a communication module configured to communicate with a computing device;
instructing the fluid collector to divert multiple samples of the production fluid to the at least one of the sample containers according to a first sample collection schedule;
monitoring one or more sensors to collect data associated with at least one of:
a location of the fluid collector;
a pressure of the production fluid;
a flow rate of the production fluid;
a pressure of a pneumatic actuation system associated with the fluid collector;
an ambient temperature;
and a level of a power supply configured to supply electrical power to the controller;
transmitting at least a portion of the collected data to the computing device, wherein the controller is configured to change the first sample collection schedule in response to the data transmitted and divert a sample of the production fluid to another one of the sample containers on the carousel upon changing the first sample collection schedule;
and
collecting the sample containers from the carousel for analysis.
