Abstract (en)

[origin: US2015075772A1] There is provided a system for effecting production of formation fluids from a subterranean formation. The system includes a gas anchor for mitigating gas lock. Sealing engagement of the gas anchor against the wellbore tubular is effected without use of a conventional packer, which would otherwise be susceptible to receiving debris deposited from the formation fluid, which thereby results in the packer, as well as the gas anchor, becoming vulnerable to becoming stuck within the wellbore tubular.
