Subject Matter Experts

From our core business of providing scientific solutions to our clients, we have developed innovative products. Some are produced internally, and some have arisen from partnerships with other research organizations. 

For example, we build lab software solutions to help manage and streamline your labs data, and environmental testing products for a variety of applications. 

  • IntelliSEM is a powerful automated particle analysis system.
  • ParticleID is  a customizable cloud hosted web application used to identify foreign particulate matter and  assist with root cause investigations. 

Other products we create count particles and help keep the air and environment safe.

RJ Lee Group is a materials analysis laboratory and consulting company which serves many different industries. We offer scientific solutions such as industrial forensics services, laboratory and testing services, litigation support, and laboratory software to many industries:

Flow Loop Evaluation of Friction Reducer Performance

Vincent B. Conrad, Ph.D.

February 21, 2017

A properly designed friction reducer (FR) system provides technical and economic performance that exceeds conventional FR systems in the oil and gas industry, particularly when using recycled produced water.  RJ Lee Group provides flow loop evaluations of friction reducer performance that are free of conflict of interest issues associated with of chemical or completion service contracts.

Controlled evaluation of friction reducers by a single, independent laboratory enables valid and accurate comparison of FR performance that is not possible when tests are completed by multiple labs whose flow loops are not designed and operated equivalently.

Figure 1. FR XYZ – 0.3 gpt – 33%FW/67%PW

Flow loop data provides a means of:

  • Comparing FRs from the same or different vendors
  • Evaluating FR performance in different water matrices
  • Evaluating the effect of other additives on FR performance
  • Minimizing FR dosage required for a specified friction reduction
  • Maximizing the volume of produced water in produced water/fresh water blended fluids

The RJ Lee Group flow loop is constructed of a progressive cavity pump and speed controller that produces flow rates ranging from 5 to 50 gpm.

Figure 2. Comparison of FR performance for Multiple Tests

The pressure drop across a section of polished stainless steel tubing in the presence and in the absence of a FR is measured to assess the magnitude of friction reduction.  The flow loop system is capable of achieving Reynold’s Numbers from approximately 25,000 to 300,000. The ability to provide FR measurements at Reynold’s Numbers exceeding 125,000 provides a more accurate simulation of field conditions than can be provided by many competitors.   Both instrument control and data logging are executed through a microcontroller and custom-developed software.  Reports include the friction reduction data and profile for each test (Figure 1) and a comparison of friction reduction for multiple test conditions (Figure 2).
