Abstract

A modular hydrocarbon production system for depleting wells that uses a dual blowcase system for enabling uninterrupted continuous production from wells that have a lower wellhead pressure that the export pipeline. The system can be advantageously enhanced with additional separators, blowcases and gas compressors for maximising production as the wellhead pressure drops with time. The use of a novel control system for ensuring a continuous flow to export avoids batch processing of wellbore fluids.

Dependent claims

A hydrocarbon production system comprising:

at least one inlet separator comprising a fluid inlet, a gas outlet and a liquid outlet;
an inlet flow line which is configured to be connected to one or more hydrocarbon producing wells and which extends to the fluid inlet of the inlet separator;
a plurality of blowcases each comprising a liquid inlet, a liquid outlet, a high-pressure gas inlet and a pressure equalization outlet;
at least one gas compression system;
a liquid export line;
a drain line associated with each blowcase, each drain line being provided with a drain valve, the drain lines extending from the liquid outlet of the associated blowcase to the liquid export line;
a gas supply line associated with each blowcase, each gas supply line having a gas supply valve, each gas supply lines extending from the gas compression system to the high pressure gas inlet of the associated blowcase;
a liquid supply line associated with each blowcase, each liquid supply line having a liquid supply valve, which extends from the liquid outlet of the inlet separator to the liquid inlet of the associated blowcase;
an equalization line associated with each blowcase, each equalization line having an equalization valve, which extends from the equalization outlet of the associated blowcase to the gas outlet of the inlet separator;
a valve controller that controls operation of the drain valves, the gas supply valves, the liquid supply valves, and the equalization valves, the valve controller being configured to control the valves so that at least one blowcase is in a fill state in which the associated liquid supply valve, and the associated equalization valve are open while the associated drain valve and associated gas supply valve are closed, and at least one blowcase is in a drain state in which the associated liquid supply valve, and the associated equalization valve are closed whilst the associated drain valve and the associated gas supply valve are open.
