Abstract

A stripper device for a wellhead defining the terminus of an aliphatic hydrocarbon production well. The stripper device includes a lubricator assembly having a lubricator pipe in communication with the wellhead and a dipper assembly traversing within the lubricator pipe and the well. A controller assembly provides instructions in a computer readable format to regulate the collection of liquid aliphatic hydrocarbons from the well with the dipper assembly. The stripper device includes a recovery assembly having a pivot element coupled to a lubricator pipe and to the wellhead. The pivot element renders the lubricator pipe to communicate with the wellhead in a first position and renders the lubricator pipe apart from the wellhead in a second position to expose the wellhead free of obstructions including those from the lubricator assembly.

Claims

1. A stripper device for a wellhead, the wellhead defining a terminus of an aliphatic hydrocarbon well, the aliphatic hydrocarbon well operating as a stripper well, the stripper device for extracting aliphatic hydrocarbons from the aliphatic hydrocarbon well, the stripper device comprising:

a lubricator assembly,

the lubricator assembly including a lubricator pipe in communication with the wellbore, a wireline, and at least one dipper assembly for collecting liquid aliphatic hydrocarbons in a dipper body and coupled to the wireline, the at least one dipper assembly for traversing within the lubricator pipe and the well when the lubricator pipe is in a first position for operation with the wellhead; and

a retrieval mounting portion,

the retrieval mounting portion including a neck and a tapered rim, the retrieval mounting portion at a first end coupled to and extending away from one end of the dipper body, the retrieval mounting portion further configured at a second end to fixedly receive a retrieval tool, wherein the retrieval mounting portion couples with a driver collar in the lubricator to actuate a pivotable flap below the dipper body via linear movement of the driver collar and the retrieval mounting portion.

2. The stripper device according to claim 1 wherein the retrieval mounting portion includes a receiving pin for receiving a removable fishing neck assembly thereon, the fishing neck assembly configured to mate with the retrieval tool.

3. The stripper device according to claim 1 wherein the retrieval mounting portion defines an integrated fishing neck for receiving the retrieval tool thereon.

4. The stripper device according to claim 1 wherein the retrieval mounting portion includes a wireline tool modular interface, and wherein the wireline tool modular interface releasably couples the retrieval mounting portion to the dipper body of the at least one dipper assembly.

5. The stripper device according to claim 1 wherein the wireline tool modular interface threadedly couples to one end of the dipper body.

6. The stripper device according to claim 1 wherein the retrieval mounting portion includes a wireline tool modular interface, and wherein the wireline tool modular interface couples the retrieval mounting portion to the dipper body of the at least one dipper assembly, the retrieval mounting portion and the dipper body are one integral piece.

7. The stripper device according to claim 1 wherein the retrieval mounting portion includes at least one tapered latch.

8. The stripper device according to claim 7 wherein the retrieval mounting portion includes a mounting portion retrieval neck, and wherein the at least one tapered latch and the mounting portion retrieval neck collectively receive the retrieval tool.

9. A dipper assembly and a stripper device, the stripper device coupled to a wellhead of a production well, the dipper assembly collecting aliphatic hydrocarbons from the production well, the dipper assembly comprising:

a dipper body; and

a removable striker unit threadably coupled to a bottom surface of the dipper body,

the striker unit including a collar enclosing an opening formed on the bottom surface of the dipper body and a collection valve,

the collection valve including a striker stem, near one end of the striker stem is disposed a compensator disposed to urge against the collar,

the striker stem is rendered between a fill position and a draw position to selectively seal liquid aliphatic hydrocarbons in the dipper body,

wherein the retrieval mounting portion couples with a driver collar in the stripper device to actuate a pivotable flap below the dipper body via linear movement of the driver collar and the retrieval mounting portion.

10. The dipper assembly according to claim 9 further comprising dipper ports defined by the dipper body, the dipper ports forming any of alphanumeric and geometric configurations on the dipper body.

11. The dipper assembly according to claim 9 further comprising a retrieval mounting portion disposed on another end of the dipper body relative to the striker unit.

12. The dipper assembly according to claim 11 wherein the retrieval mounting portion includes a receiving pin for receiving a removable fishing neck assembly thereon, the fishing neck assembly for receiving a retrieval tool.

13. The dipper assembly according to claim 11 wherein the retrieval mounting portion includes a wireline tool modular interface, and wherein the wireline tool modular interface releasably couples the retrieval mounting portion to the dipper body of the dipper assembly.

14. The dipper assembly according to claim 9, wherein the collar defines a plurality of recessed passageways that facilitate flow of the liquid aliphatic hydrocarbons when the striker stem is rendered in the draw position.

15. A dipper assembly and a stripper device, the stripper device coupled to a wellhead of a production well, the dipper assembly collecting aliphatic hydrocarbons from the production well, the dipper assembly comprising:

a dipper body;

a retrieval mounting portion disposed on and extending away from one end of the dipper body,

the retrieval mounting portion including a neck, a tapered rim and a receiving pin,

the receiving pin at one end of the retrieval mounting portion and configured to interface with a fishing neck assembly,

the fishing neck assembly coupled to a wireline and the wireline coupled to a control module,

the fishing neck assembly further configured to couple with a driver collar in the stripper device, and when the fishing neck couples with the driver collar, the driver collar actuates a pivotable flap through a rod via linear movement of the dipper assembly,

the control module including at least one processor, and

the at least one processor implementing a program rendered in a computer readable format for positioning the dipper assembly within the production well and for correcting position of the dipper assembly with respect to the aliphatic hydrocarbons in the production well with the wireline coupled to the dipper body at the fishing neck assembly and for;

a removable striker unit disposed on a bottom surface of the dipper body,

the striker unit including a collar enclosing an opening formed on the bottom surface of the dipper body and a collection valve extending from the collar,

the collection valve including a striker stem,

near one end of the striker stem is disposed a compensator disposed to urge against the collar; and

the removable striker unit further configured to engage the pivotable flap when the pivotable flap is actuated by the driver collar when the fishing neck assembly moves the driver collar linearly.

16. The dipper assembly according to claim 15 further comprising a sensor for identifying a fluid boundary.

17. The dipper assembly according to claim 15 wherein the retrieval mounting portion includes a plurality of receiving pins, each receiving pin for receiving its own fishing neck assembly.
