Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
31 words
A separator as in claim 1, where the open ring ends are closed and one end of the ring receives the crude and the other end discharges the oil and gas.
Claim 2
Dependent Claim
22 words
A separator as in claim 1, including an infrastructure which is rigidly connected to the wellhead, the ring-shaped separator surrounding the wellhead.
Claim 3
Dependent Claim
33 words

Claim 5
Dependent Claim
14 words
A separator as in claim 1, where the ring consists of cylindrical juxtaposed sections.
Claim 6
Dependent Claim
94 words
A separator as in claim 1, where the housing consists of an assembly of tubular sheaths connected around a head of a well to form a continuous tubular envelope, one of the sheaths including a manhole for access to the interior of the envelope, the ring separator having ends that terminate adjacent the manhole, securement means fixed to the upper portion of the housing, a collar screwed to the head of the well, arms articulated from the collar to the securement means, and a separator supporting means attached to the base of the wellhead.
Claim 7
Dependent Claim
94 words
A compact separator for separating gas and oil from crude received from a wellhead comprising; a housing with an opening for receiving the crude, a closed curved channel means in the form of an open ring connected to the opening for creating a centrifugal force with the flowing crude to encourage separation of gas and oil and output means for separately removing the oil and gas, whereby the open ring ends are closed and one end of the ring receives the crude and the other end discharges the oil and gas through separate conduits.
Claim 8
Dependent Claim
