Abstract

Embodiments of a forged flange lubricator and systems incorporating the same are described. In an embodiment, the forged flange lubricator may include a main body configured to receive fluid raised by a plunger lift assembly from a well. Additionally, the lubricator may include a port in the main body configured to conduct fluid as it is received by the main body, wherein the main body and the port are a unitary structure devoid of applied junctions.

Claims (35)

1. An apparatus, comprising:

a main body configured to receive fluid from a well;

a first flange on the main body;

a second flange on the main body;

a first port in the main body associated with the first flange;

a second port in the main body associated with the second flange; and

a third port in the main body;

wherein the main body, the first flange, the second flange, and the first and second ports, are a unitary structure devoid of applied junctions, and

wherein at least one of the first and second flanges is located on a side wall of the main body.

2. The apparatus of claim 1 , wherein at least one of the first or second flanges further comprises fixation points that are configured to receive a fastener to thereby fasten a peripheral component to the flange.

3. The apparatus of claim 2 , wherein at least one of the first or second flanges further comprises a groove for receiving a sealing member, the sealing member configured to form a seal between the flange and the peripheral component.

4. The apparatus of claim 1 , wherein the first flange is configured to interface with a wellhead.

5. The apparatus of claim 1 , further comprising a support structure disposed around the first port and the second port for strengthening a region of the main body surrounding the port.

6. The apparatus of claim 1 , further comprising a third flange on the main body, wherein the third flange and the main body form a unitary structure devoid of applied junctions.

7. The apparatus of claim 1 , wherein the third port further comprises a sensor port configured to receive a sensor device.

8. The apparatus of claim 7 , further comprising a plurality of sensor ports, each sensor port and the main body forming a unitary structure devoid of applied junctions.

9. The apparatus of claim 1 , further comprising a plunger catcher assembly configured to catch and release a plunger as it is received by the main body.

10. The apparatus of claim 9 , wherein the plunger catcher assembly further comprises a spring.

11. The apparatus of claim 10 , wherein the spring is a progressive rate spring assembly.

12. The apparatus of claim 9 , wherein the plunger catcher assembly is housed, at least in part, in a removable extension coupled to the main body.

13. A system, comprising:

a well assembly comprising a well bottom, a wellhead, and a well pipe;

a plunger lift assembly configured to lift fluid from the well;

a bumper assembly disposed proximate to the well bottom and configured to catch the plunger lift assembly; and

a lubricator disposed proximate to the wellhead, the lubricator comprising:

a main body configured to receive fluid raised by the plunger lift assembly from the well assembly;

a first flange on the main body including one or more fixation points;

a second flange on the main body including one or more fixation points a first port in the main body associated with the first flange for receiving fluid from a well;

a second port in the main body associated with the second flange for conducting fluid into or out of the main body; and

a third port in the main body;

wherein the main body, the first flange, the second flange, and the first and second ports, are a unitary structure devoid of applied junctions, and

wherein at least one of the first and second flanges is located on a side wall of the main body.

14. The system of claim 13 , wherein the first or second flange is configured for receiving a mating flange of a peripheral component to interface with the lubricator.

15. The system of claim 13 , wherein the first flange is configured to interface with the wellhead.

16. The system of claim 13 further comprising a third flange on the main body, wherein the third flange and the main body form a unitary structure devoid of applied junctions.
