DYNAMOMETER TEST

Anatesco has spent over 30 years running Dynamometer tests and developing our own accurate analysis of an oil well pumping system, while using computerized mobile testing vehicles. With this mobility, test results are generated on site in a matter of minutes. We understand the importance of establishing the overall system efficiencies of any well that is being produced, so each Dynamometer test we run includes:

A Dynamometer test is extremely useful when there is a problem with the pumping system, from production to rod problems to balancing issues. This type of testing is also effective before or after the purchase of a lease or group of wells to determine the problems and or the potential of each well.

SONIC FLUID LEVEL TEST

This test is used to determine the distance to the liquid level in the casing annulus of a well. A pressure pulse is generated from the fluid level equipment (compact gas gun) attached to the surface casing annulus valve. The pressure pulse travels down the casing annulus and records collars, the liquid level and other obstructions. A microphone in the compact gas gun sends the recorded collar pulses back to a strip chart recorder, which displays them on a strip of paper. The recorded strip chart shows the number of tubing collars from the surface to the liquid level and hence the depth of the liquid level can be determined.

TORQUE ANALYSIS

This test consists of an API torque calculation of the following at each 3 degrees of crank rotation:

Also included are plots of:

The Torque Analysis is run to determine the current balance of a pumping unit and the loading on the gearbox, as well as determining the proper sizing of pumping equipment to well conditions. We believe that every producing well in the oilfield should be operated at peak performance and efficiency. That includes the balancing of the equipment to save on power costs and unnecessary equipment wear. This test has also been required from unit manufacturing companies to validate warranties. Note: The Torque Analysis "must" be run in conjunction with the Dynamometer test to determine an accurate Counter Balance Effect.

PUMP-OFF CONTROLLERS

We sell, install and repair D-Jax "Penny Pincher" Pump-Off Controllers. These controllers do not use strain gauges or any type of load cell to detect pump-off. The patented D-Jax pump-off detection is achieved by measuring pumping speed increases in milliseconds, as the well pumps down.

By eliminating the load cell strain gauge, this controller can offer producers and operators a pump-off control that is less costly to purchase, install and maintain. Also the D-Jax controller is simple to calibrate and stays calibrated.

The simplicity of this controller makes it a very "user friendly" device for field personnel to operate and maintain. Also, the "Fiber Optic" circuitry greatly reduces the chances of power surges and electrical "spikes" causing catastrophic damage to the control logic board.

The controller is designed to help reduce lifting costs and unnecessary wear on your surface and down hole equipment. A well that pumps off should only run when there is ample amount of fluid to be produced. Once the well reaches a pumped-off state, it needs to shut down. Evidence has found that a clock or a percentage timer cannot match the effectiveness of a Pump-Off controller.

PRESSURE TRANSIENT TESTING

In our continued efforts to supply our customers with the services they desire, we have the ability to run Pressure Transient Testing. This testing is performed using a completely automated computerized fluid level machine mounted in a trailer. This equipment can constantly monitor fluid level, casing pressure, gas temperature and bottom hole pressure over time. With this information you then can accurately calculate:

After analyzing the data collected you can determine, among other things, pre-fracture and post-fracture pressure build-up, draw down, injection and fall off tests. This testing is done and the information is gathered without the expensive cost of pulling the well and the lengthy downtime. After the test is completed the well then can be turned back on and put in production.
