Dynamometer Testing

There has not been introduced to the oil industry a more powerful or important diagonstic tool in the past 100 years than the modern dyanmometer survey.

To those that understand the science and application of the "dyno" comes the assurance that their optimization and diagostnic needs can be met in a cost effective and elegant manner.

To those who do not understand the underpinnings of dyno technology comes the frustration of operating producing wells in a never ending process of trial and error, guesstimating, and tail chasing.

Presented here is an overview of the dyno fundamentals and some of the "science" that hopefully sheds light on the often misunderstood "how, when, where, why" of the dynamometer process.

How does it work?

Dyno Basics

VET

Totally Electronic Test

Multiple surface dynamometer traces in the stabilized pumping modeare digitized and stored electronically. A single representative trace is used in conjunction with a seriesof valve checks to calculate and report the following.Standard quantitative rod loads (peak, SV,TV, etc.),pump fillage, pump slippage, net plunger travel, gross& net pump displacements, pump efficiency, intakepressure, fluid level, MGDA Rod Stress, polished rodhorsepower, downhole transform (finite differencemethod) and acceleration factor. Also reported:Additional trace after a short downtime (downcard),casing & tubing pressure, flowline temperature, andcoded comments as warranted. Significant data can be summarized in action reports in multi well projects sothat candidates for production enhancement and cost savings can be quickly isolated. Action reports can begenerated electronically via Dynoeze (our free Dynamometer Processor) or submitted by conventionalmeans (paper). .

Mini Vet

Is an abbreviated version of the VET with a single normal trace and qualitative loads.Missing from the VET: Net plunger travel, intakepressure, fluid level, rod stress, PRH, down holetransform, and pretest traces. Includes line temps andpressures if requested. Mini VET's also integrate withDynoeze.

• Up to 28 action, safety, production, and maintenance reports and work lists are an integral part of the above services. These customizable reports are typically generated at the end of each project or at the end of themonth (when there is more than one project) to ensureproblem wells and opportunities for improvement are clearly identified and communicated to responsibleparties. Examples: High fluid level wells with over20% pump slippage, bad polished rods, out of balance units, less than 20% pump fillage for the last 3 months,hydrogen sulfide detected, and so on.

• The TET runs on a PC. Client based Dynoeze software allows full and free access to field data. Over 100 coded comments communicate previously ignored field conditions. Includes built-in database reports, dyno-viewer, e-mail communicator, electronic orderingand delivery, autospotter, and several other features.Requires 32-bit operating system. Please refer to TETapplication notes and other documentation for additional details (available at http://anatesco.com ).

Micro Vet

Consists or a single surface dynamometer trace reported 24 to a page with pumpfillage. Includes a summary of fillage, stroke speed &length. Valve checks not included. Includes line tempsand pressures if requested. Can also be viewed in Dynoeze.

PET

Production Efficiency Test

Same as theVET (above) except a clamp style transducer is used instead of a load cell. The PET has proven useful whenthe “Dyno” is to be used as a production “gauge” asseveral traces are averaged to obtain a more representative fillage value, which translates to a morereliable pump displacement rate.
