## Abstract

A method and apparatus for separating of gas from liquids in a wellbore, the apparatus enabling the receiving of wellbore fluids into two or more production separation chambers, operating in parallel. The apparatus further enabling the receiving of production separation chamber fluids into a production pipe through a thief jet port disposed in a lower chamber beneath the production separation chambers. The apparatus further enabling extraction of bottom hole gas fluids in the wellbore from under the two or more production separation chambers and disposing the gas fluids back into the wellbore above the two or more production separation chambers.

## Claims

### Claim 1

An apparatus for feeding gas-containing well production fluids into a downhole gas separator system, the apparatus comprising:
a feed cylinder assembly separated vertically into an upper chamber and a lower chamber; a collecting tube extending into the upper chamber and the lower chamber;
wherein the upper and lower chambers are partially isolated from each other by an annular ring, disposed between an outer wall of the feed cylinder assembly and the collecting tube, whereby a partial barrier is formed to control the vertical flow between the upper chamber and the lower chamber;
an upper opening in the upper chamber connecting the feed cylinder assembly to the downhole gas separator system;
a lower opening in the lower chamber configured to connect the feed cylinder assembly to a supply of the gas-containing well production fluids;
an upper orifice in the collecting tube disposed in the upper chamber; and
a plurality of orifices in the collecting tube disposed in the lower chamber, wherein each of the plurality of orifices is smaller than the orifice in the collecting tube disposed in the upper chamber;
wherein the collecting tube is configured to pass a flow of the gas-containing well production fluids from the supply of the gas-containing well production fluids, into the plurality of orifices, through the upper orifice, and through the upper opening to the downhole gas separator system.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the downhole gas separator system includes a pressure loss cylinder, and wherein the upper opening in the upper chamber connects the feed cylinder assembly to the pressure loss cylinder.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein tube stubs are disposed in the annular ring, and wherein the upper chamber and the lower chamber are connected through the tubes stubs.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the plurality of orifices in the collecting tube disposed in the lower chamber are sized and configured to filter particulates from the gas-containing well production fluids.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the collecting tube is attached to a block that is attached to a production tube, whereby direct flow from the collecting tube into the production tube is prevented.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein the feed cylinder assembly is distinct from the downhole gas separator system.

### Claim 7 (depends on 1)

The apparatus of claim 1, wherein the upper chamber and the lower chamber are positioned below the downhole gas separator system.

### Claim 8

An apparatus for feeding well production fluids into a downhole gas separator system, the apparatus comprising:
a feed cylinder assembly separated vertically into an upper chamber and a lower chamber; a collecting tube extending into the upper chamber and the lower chamber;
wherein the upper and lower chambers are partially isolated from each other by an annular ring, disposed between an outer wall of the feed cylinder assembly and the collecting tube, whereby a partial barrier is formed to control the vertical flow between the upper chamber and the lower chamber;
an opening in the upper chamber connecting the feed cylinder assembly to the downhole gas separator system;
a lower opening in the lower chamber configured to connect the feed cylinder assembly to a supply of the well production fluids;
an orifice in the collecting tube disposed in the upper chamber;
a plurality of orifices in the collecting tube disposed in the lower chamber, wherein each of the plurality of orifices is smaller than the orifice in the collecting tube disposed in the upper chamber; and
tube stubs disposed in the annular ring connecting the lower chamber and the upper chamber.

### Claim 9

An apparatus for feeding well production fluids into a downhole gas separator system, the apparatus comprising:
a feed cylinder assembly separated vertically into an upper chamber and a lower chamber; a collecting tube extending into the upper chamber and the lower chamber;
wherein the upper and lower chambers are partially isolated from each other by an annular ring, disposed between an outer wall of the feed cylinder assembly and the collecting tube, whereby a partial barrier is formed to control the vertical flow between the upper chamber and the lower chamber;
an upper opening in the upper chamber connecting the feed cylinder assembly to the downhole gas separator system;
a lower opening in the lower chamber configured to connect the feed cylinder assembly to a supply of the well production fluids;
an upper orifice in the collecting tube disposed in the upper chamber; and
a plurality of orifices in the collecting tube disposed in the lower chamber, wherein each of the plurality of orifices is sized and configured to filter out particulate material from the well production fluids.
