Plunger Lift Testing the Two Piece PlungerThere are many instances where using this plunger results in gas production increases. However in some cases, it appears to have a lesser effect.

2 Mule ShoeDavid Simpson

Vortex Tool Vortex DX ToolsA review of this emerging technology that has shown considerable promise in lowering the critical rate required for a free-flowing well to unload liquids.

3 Vortex Flow, LLCBrad Fehn

Vortex Tool Vortex FlowThe Vortex Flow tools are a breakthrough in fluid dynamics and create a more efficient flow pattern of fluids through a piping conduit.

III. Case Studies Chair: Norm Hein, Tony Podio1 Compressco

Ted D. Garner

Wellhead Compression Case Histories- Wellhead Compression/ Lower Wilcox-Lobo Trend in South TexasThis paper presents case histories of wells under various operating conditions, and the benefits of wellhead compression in preventing liquid loading.

2 ConocoPhillilpsLarry Harms

Wellhead Compression Case History: Unloading Tight Gas Wells with Wellhead CompressionThis will show details from recent experiences we have had with substantial increases in rate (over 300 MCFD per well) and reserves (200-1000 MMCFD added per well).

3 BPJess Babbitt Gordon Gates

Practical Learning Practical Learning from Operating LP Gas WellsThis presentation is intended to point out many practical learning’s in the operation, completion, and drilling of low-pressure gas wells.

4 PolyFlow, Inc.Jay Wright

Polymer Tubing Reinforced Polymer Tubing to Enhance Liquid Lifting of Gas Wells Cur-rently Loading With Water A summary of suitable and unsuitable well operating parameters will be detailed to assist in proper well selection for this technology.



5 Kinder MorgenRebecca J. Larkin

Tubing Design Innovative Tubing String Design Improves Flow ProfileCandidate selection, design criteria and tubing hardware employed, installation procedure, and ac-tual well performance are described.

6 Dyna-Coil Dave Smith

Capillary Lift Case Histories of Capillary Lift Enhances Gas Production in 1000s of wells in the USAThis paper presents the case histories of several thousand wells that have been completed with capillary tubing for the purpose of lifting fluids via down hole sur-factant injection.

IV. Automation / Modeling Chair: Dave Christmas, Cleon Dunham1 BP Gas Well Automation How BP approached remote automated gas well deliquification

Case history of trending samples of gas wells with varying degree of liquid loading problem and con-trol solution will be presented and discussed. Also diagnostic and analysis technique to identify equipment failure and improper operating practices will also be presented.

2 Shell International EPPaul verBeek

Controlled Production Controlled Production fromUnstable Liquid Loaded Gas Wells

3 ConocoPhillipsLarry Harms

Integrated Model Better Results Through Integrated Production ModelingThis presentation will include the integrated production modeling (IPM) tools available to show why results are not always what we think they should be when we don't look at the whole system (facili-ties, wellbore, reservoir).

4 Dyna-CoilDave Smith

Two-Phase Flow Model Method of Selecting Well Candidates for Dewatering Using an Empirically Modified 2 Phase Flow Computer ModelThe method of enhancing gas production by optimally placing a foaming agent in a well via capillary tube has been now proven successful in over 5,000 wells in the USA.
