Session 23 Dec 2nd 2020 Identifying Holes in Tubing on Sucker Rod Lifted Wells
Session 23: When an operating Sucker Rod lifted well is found to have no production to surface, then a recommended practice is to shoot a fluid level down the casing annulus and also shoot a fluid level down the tubing. Analysis of the acquired acoustic data is used to determine such things as: If there is a hole in the tubing. Show ineffective pump operation with tubing shots acquired at uniform time intervals, where “pumping up” the tubing occurs too slowly. Require additional tubing back-pressure, since tubing liquid was unloaded from too much gas produced through the pump and up the tubing. Down tubing fluid levels is an effective troubleshooting technique. Fluid level shots, in conjunction with high speed tubing pressure data and dynamometer test provides the operator with enhanced troubleshooting capability to identify a hole in the tubing. A sudden drop in production in a sucker rod pumped well may be caused by the HIT.
Session 22 Nov 11th 2020 Motor Power-Current-Voltage Measurements and Analysis
Session 22: High‐frequency motor power‐current‐voltage measurements are used to analyze the electrical and mechanical performance of pumping units. TAM Software in receives and analyzes the data to determine power usage, power generation, pumping unit balance, gear box upstroke and downstroke torques, motor loadings, and power line loss. Power line loss is an analysis performed to analyze the power line loss between the electrical system and the pumping unit motor. The counter‐weight movement for gear box balance is determined easily without use or knowledge of the pumping unit dimensions.
Session 21 Oct 14th 2020 Over Travel Occurs on Up and Down Stroke: Benefits of High Speed and Resolution Data Acquisition
Session 21: The surface dynamometer card down or up slope from left to right defines an "Over travel Card" or an “Under travel Card”. Rod stretch creates the under travel cards. Pumping fast or high plunger velocities created by the sudden release of load creates over travel cards. Pump sudden load changes and resulting velocity changes occurring along the sucker rod string away from the beginning of the up stroke or the beginning of the down stroke cause an increase in equipment down hole failures. The sudden load and velocity change results in rod on tubing contact, increased rod on tubing wear, and impact loads. Often delayed closing or delayed opening of the standing or traveling valve occurs during sucker rod pumping of gassy unconventional wells. High speed and high resolution data will be used to identify how the pump is performing and to clearly analyze the severity of sudden impact loads.
Session 20 Sept 30 2020 Sucker Rod Pumping System Design - QRod 3.1
Session 20: QRod is the most widely used Sucker Rod Pumping design program. This program displays results in any system of units and uses a damped wave equation to accurately predict the surface and pump dynamometer loads, gearbox torque and pump capacity, with minimum input. QRod’s objective is to help the beam pumping system designer implement state of the art design technology without getting buried with details. Changing parameters such as tubing anchor, stroke length, stroke rate, or pump diameter is immediately seen in # #oilgas dynamically updated plots. Patterson equation in Pump Slippage Calculator allows specifying pump clearance to determine the pump slippage, pump efficiency and to predict the net pump displacement. This and other QRod features will be discussed during the presentation.
Session 19 Sept 23 2020 Conventional and Bypass Plunger Performance: Advantages of Tracking a Plunger
Session 19: Plunger Lift operations can be difficult to optimize due to lack of knowledge of tubing pressure, casing pressure, bottomhole pressure, liquid accumulation in the tubing and location of the plunger. Knowing the plunger position in the tubing helps the operator to understand the operation of the plunger system in order to optimize the removal of liquids and gas from the well.Plunger Lift operations can be difficult to optimize due to lack of knowledge of tubing pressure, casing pressure, bottomhole pressure, liquid accumulation in the tubing and location of the plunger.

Session 18 Sept 16 2020 Downhole Gas Separators
Session 18: Many Sucker Rod Lifted wells having gas interference operate with less than 30% liquid pump fillage. Often, the main cause of inefficient operations is either NO downhole gas separator or one that is inefficient. To identify gas interference as the cause of this problem, obtain an acoustic liquid level test which indicates a high gaseous liquid column above the pump intake and analysis of the dynamometer data will indicates incomplete pump fillage. To correct your pump's gas interference problem, install a gas separator below the pump. Correct design results in complete pump fillage, if sufficient liquid inflow into the wellbore is available.
Session 17 Sept 9 2020 TAM Software Dynamometer Features and Navigation
Session 17: Learn the TAM Software Dynamometer features. During this session, we navigate the TAM Dynamometer buttons and features, and demonstrate the "hidden" tools are resources available for dynamometer data analysis. If you are new to the TAM software, or interested in a TAM navigation overview, please join us for this session.
Session 16 Sept 2 2020 The Three Main Causes of Incomplete Pump Fillage
Session 16: Incomplete pump fillage is often associated erroneously with a “pumped-off well”, meaning that the pump displacement exceeds the production capacity of the reservoir, ignoring the fact that there are two other causes of partial liquid fillage: gas interference and the presence of a flow restriction or excessive pressure drop at the pump intake. The result of a misdiagnosis is to incorrectly set the mode of operation of pump-off controllers, variable speed drives or timers thereby loosing significant amounts of production. This Ask (((ECHOMETER))) presentation describes the three causes of incomplete pump fillage, presents several sets of field data for the various cases, discusses how to combine dynamometer and fluid level records to correctly identify the source of the problem and presents recommendations for possible solutions.
Session 15 Aug 26 2020 TAM Software Liquid Level Features and Navigation

Practical application of the analysis information covered in past Ask Echometer sessions will be demonstrated. Presented by Lynn Rowlan, Tony Podio, Carrie-Anne Taylor and Gustavo Fernandez.
Session 8 July 8 2020 Troubleshoot and Analyze Sucker Rod Wells Using Reference Load Lines and Pressure Annotations
Session 8 Pump cards have three load reference lines 1) Zero Load line, 2) Fluid Load line from Fluid Level, Fo, calculated using the pump intake pressure determined from an acoustic Fluid Level measurement, and 3) Maximum Fluid Load, Fo max, line calculated by setting the pump intake pressure equal to zero. Certain downhole pump problems can be recognized based on the location of the pump card loads with respect to the three load reference lines. When there is no apparent pump action the load value of the flat pump card can be used to determine if there is 1) a shallow rod part, 2) a deep rod part or traveling valve, TV, is stuck open, 3) Tubing is dry of well fluids, 4) the standing valve, SV, is stuck open or 5) the SV is stuck closed with no fluid is entering the pump. Typical pump card loads plot near zero load line on the down stroke and the loads plot near Fo from Fluid Level load line on the upstroke. Presented by Lynn Rowlan.
