Webinar: Oil Well Dynamometer Card Analysis
Author: Ed Chesny
Pumpjacks are a common part of the driving landscape in oil producing regions of this country, but have you ever wondered about what is going on underground? Or how an industry professional knows if the equipment downhole is working as it should or supposed to? The tools connected to that pumpjack are going up and down, but are they functioning as expected? On the downhole end of the pumping string is a precision tools commonly known as a bottom hole pump.
This Live Webinar course introduces the basic tools used to diagnose how this oil well sucker rod pump can be analyzed to evaluate the system condition and performance without the cost of pulling it out of the hole.
These diagnostic tools conduct what is known as oil well dynamometer testing that can evaluate performance. The information gained from these tools can be quite valuable for it can be used to modify or adjust how a well is being pumped to increase productivity, avoid equipment damage, minimize production downtime, eliminate the need for repair work, and/or extend pump life.
The data points generated are used to create and plot charts or diagrams which can be interpreted to determine the downhole pump and pumping system condition.
This webinar will place an emphasize on:
- How the dynamometer tools gather data.
- What a dynamometer survey can tell the analyst about the pumping system tested.
- The surface measured load change and acceleration as described on a load vs. displacement card.
- The downhole card developed using interpretations of the surface measurements by means of wave and elasticity equations.
- Learning what the basic card shapes look like, reasons for shape created, and what it can mean to the analyst.
- Diagnosing the effects of the most common operational problems with rod pumping systems:
- Gas Interference
- Solid – Sand Other Trash
- Incomplete Pump Fillage
- Over Pumping
- Pump Hitting
- Exposure to the complex card shapes possible when interpreting downhole pumping conditions.
This Live Webinar course is intended to provide you with the following specific knowledge and skills:
- Learn how dynamometer testing tools function to evaluate and optimize crude oil pumping equipment as it lifts products to surface from a subsurface reservoir.
- Provide historical background on the creation of dynamometer testing equipment, how they have evolved over time and how the equipment manufacturers are continually working to improve them.
- Learn how the dynamometer tests evaluate parts of the rod pumping system to measure & enhance performance of the process.
- Learn how the dynamometer measurement process produces downhole pump cards which can be interpreted to establish the condition of the bottomhole pump.
- Learn how the surface card measurements are recorded from the polish rod of a pumping unit.
- Learn how the downhole pump card is calculated to interpret the movement of the pump plunger.
- Learn the produced card relates to downhole pump and valve movements as well as pump chamber fill.
- Learn how the card can be used to ascertain the mechanical condition of the pump, pump fillage, and the valve system function.
- Learn how a card pattern can be useful in finding other subsurface mechanical problems with friction or tubing anchoring.
- Learn how the card can be used to see how reservoir gas can and does interfere with the pumping process.
- Learn how many different operating problems are displayed and can be detected from card analysis before incurring the cost of pulling a well.
