Definitions

  • natural gas indicates any gas occurring in nature in a porous and permeable underground formation.
  • methane is a dominant component of natural gas although hydrogen sulfide, carbon dioxide and other gases may comprise the bulk of a natural gas.
  • the history of production of a typical natural gas well is basically follows. Upon initial production of a gas bearing reservoir, the formation pressure is sufficient to move gases existing in the formation as well as liquids existing in the formation into the wellbore.
  • the formation pressure is also sufficient to move the downhole gaseous and liquid components through a production string to the surface. As fluids are produced from the formation, the formation pressure decreases. After production has continued for some time. gas wells typically begin to produce a detectable quantity of water which is known to be liquid in the formation and which is normally saline. At the onset of salt water production, the wellhead pressure begins to drop at a fairly rapid rate which is merely a manifestation of the weight of liquids in the production string since the formation pressure continues to decline at a rate which can be predicted from the quantity of formation fluids produced. Sooner or later, the formation pressure adjacent the wellbore declines to a value which is insufficient to deliver a sufficient gas volume through the production string to produce or unload liquid components therein.
  • these liquid components accumulate in the production string until the weight of the liquid column substantially balances the formation pressure adjacent the borehole whereupon the well dies.
  • the accumulation of formation liquids in the production string is typically attributable to a low linear velocity of fluids in the production string. It is generally believed that formation fluids must flow upwardly through a conventional sized tubing string at about 5-10 feet/second in order to propel liquid droplets up wardly through the tubing string against the effect of gravity.
  • the gas volume delivered through the tubing string drops and the linear velocity of gas through the production string declines until liquids begin to accumulate in the production string.
  • This primary objective is accomplished by positioning a gas jet compressor in the production string with the low pressure inlet in communication with the gas bearing formation. Relatively high pressure natural gas is continuously delivered to the power fluid inlet of the compressor. The mixture of the produced formation fluids and the power fluid is continuously withdrawn from the high pressure outlet of the compressor and delivered to the production string. It is known in the prior art to utilize jet eductors or ejectors in conjunction with petroleum producing wells, as shown in U.S. Pat. No. 2,061,865; Journal of Petroleum Technology, April, 1966, pages 419-23; Power and Fluids, Fall 1954, article entitled Gas Jet Compressors; World Oil, Feb.
  • the publications in the Journal of Petroleum Technology, Power and Fluids, and World Oil basically disclose the incorporation of gas jet compressors as surface equipment in gas producing wells utilizing high pressure natural gas as the power fluid.
  • the Southwestern Petroleum Short Course paper discloses a downhole jet pump for moving liquids upwardly through a producing string utilizing high pressure liquid as the power fluid.
  • this invention comprises the method of substantially continuously producing natural gas at the surface from a well providing a first fluid passage affording communication between an underground formation which gives up both natural gas and a liquid wherein the formation flowing pressure and/or volume is insufficient to continuously flow the gas and liquid through the first passage to the surface, and a second fluid passage extending from a source of natural gas at a second pressure greater than the formation flowing pressure to the formation, the method comprising the steps of (1) continuously delivering natural gas from the source to a power fluid inlet of a gas jet compressor located adjacent the formation; (2) continuously withdrawing natural gas and liquid from the formation and directing the same into a low pressure inlet side of the compressor, a high pressure outlet side of the compressor being in communication with the first passage; (3) continuously withdrawing a mixture of the gases of steps (1) and (2) and the liquid of step (2) from the compressor at a pressure intermediate the formation flowing pressure and the power fluid inlet pressure and at a volume sufficient to overcome the effect of gravity on liquid droplets; (4) continuously passing the mixture upwardly through the first passage to the surface;

  • a latch actuator 90 Surrounding the stinger 86 and axially movable therealong is a latch actuator 90 having a collar 92 on the lower end thereof captivated to the collar 84.
  • relative downwardly movement of the latch actuator 90 causes the latch elements 80 to bear against the wedging surface 76 and expand outwardly into load bearing engagement with the latching shoulder 38.
  • Relative downward movement of the stinger 86 causes the wedging surface 76 to retreat from the latch elements 80 allowing the same to retract out of engagement with the latching shoulder 38 thereby freeing the tool 40 for movement inside the landing nipple 36.
  • the latch actuator 90 comprises a shoulder 94 thereon.

  • the shoulders 88, 94 allow manipulation of the tool 40 to land and retrieve the same from the nipple 36 in basically the same fashion as an Otis Type N Mandrel.
  • the tool 40 is a wireline tool which is placed in and retrieved from the tubing string 26 in accordance with known techniques. It will be apparent to those skilled in the art that the tool 40 may be incorporated as a section of the tubing string 26. This may be advantageous when completing a well through small size strings, e.g., a 2 /8 inch casing string and a 1V2 inch tubing string.

  • the tool 40 is installed in the production string 26 at a stage of exploitation of the formation 16 when the formation flowing pressure and/or volume is insufficient to continuously produce all liquids appearing in the tubing string 26 to the surface. As previously discussed, this typically occurs after the formation 16 has been produced for a substantial length of time and the flowing pressure thereof declined substantially.
  • the well may load up and die as a result of hydrocarbon liquids occurring in the production string 26 even though the pressure in the formation is substantial.
  • the tool 40 is typically installed when the well begins to load up and die.

The pressure drop in the flow line 112 and the annulus 34 is probably on the order of 1-2 psi and is accordingly negligible.

  • Approximately 1,000 MCFD at 40 psia passes through the pup joint 70 into the production string 26. This quantity of gas passes through the production string 26 and the flow line 98 into the free water knockout 100.

  • the effect of the tool 40 is two-fold.
  • a linear velocity on the order of 5-10 feet/- second is widely believed necessary to elevate liquid droplets in the production string 26 to the surface.
