Abstract

 

Qualifying proppant performance prior to a frac job, or simply verifying proppant performance after a frac job, can add significant value to propped fracture stimulations.  Through a blend of established practices and new technology, data can be generated that will give an engineer insight into how specific proppants are designed to perform.  This is without running expensive and time consuming conductivity and permeability tests on every job.

 

A primary objective is to establish representative, reliable and reproducible data via a sample collected from a large mass.   American Petroleum Institute (API) Recommended Practices (RP)   identifies three primary tenets:  1) representative sampling from a flowing stream, 2) standardized testing with calibrated equipment, and 3) sample retention for follow-up evaluation.  Application of these practices ensures that proppant test data is valid (e.g. representative, reliable, and reproducible).  Yet, these practices alone typically quantify quality but do not qualify proppant performance.  

 

Correlation of valid well-site proppant data with published information (literature, web-sites, or fracturing simulators) enables one to identify disparities.  Any differences in part may be the result of mining anomalies, manufacturing defects, transportation abuse, and/or contamination.  These can directly impact the delivered performance of your chosen proppant.  Since proppant flow capacity or conductivity is a key measure of that performance, some empirical results have been assimilated for well-site and public data.

 

As a consumer, having information that describes the proppant at the well-site is important to deciding application and value.  By compiling historical well-site proppant data one can set a minimum threshold of required properties or specification.  This provides the opportunity to identify a greater range of proppants (e.g. substitutions) that meet reservoir, economic, and supply chain needs.

 

Lastly, new patent-pending technology is presented that enables well-site proppant sampling and evaluation before the fracturing treatment.  Having pre-frac data gives one the opportunity to make any necessary changes in fracture design and implementation to get the most from available proppant.  It also provides for a detailed inspection of the well-site delivered proppant supply.  For instance, one can isolate and sample each pneumatic trailer, monitor associated pneumatic discharge pressures, provide representative split samples for fracturing fluid compatibility testing, etc.

 

Case histories, onshore and offshore, support “qualifying proppant performance”.

Prop Tester, Inc.

Mr. Earl R. Freeman is currently Executive Vice President, PropTester Inc., headquartered in Cypress, Texas.  He has more than 28 years of experience in the oilfield service & supply sector in the areas of research, product development, engineering, operations, sales, and management.


Prior to joining PropTester, Mr. Freeman was Sales & Marketing Manager, Oilfield Technology Group, Borden Chemical, Inc (BCI), and he was responsible for sales in North America and International markets during his tenure.  Mr. Freeman began his career with the Western Company of North America (WCNA) in the late 1970s, spent 15 years with BJ Services (BJS), and a total of 9 years with BCI.  Notably, while at the Western Company, Mr. Freeman helped to assemble a proppant testing laboratory, which contributed with other proppant supply chain companies to the eventual development of API recommended practices (e.g. API RP 56).


Mr. Freeman earned a B.S. in Biology from the University of Texas at Arlington.  He is an active member of the Society of Petroleum Engineers (SPE), the American Chemical Society (ACS), and the Permian Basin Petroleum Association (PBPA).  Mr. Freeman was elected to SPE distinguished membership in 2004 after nearly three decades of service to the petroleum industry, the SPE organization, and its governing body, the SPE International board of directors. He is currently an active member of the SPE Public Service Award committee.


Mr. Freeman is an author of several SPE papers on fracturing & cementing and two United States patents on well stimulation. He also serves on the Technical Advisory Board of the   Energy Literacy Project based in Golden, Colorado.
