American Oil and Gas Reporter – February 1997 – This is an excellent article written by J. L. Prouty of the AOGR about the Stren Maximizer Down Hole Gas Separator. It is informative and clearly written, explaining what the Maximizer does and what it can save an operator/producer. If you have questions about how to stop gas locking and pounding in your well and/or how to increase the pumping efficiency without breaking the bank, this is one you should read.

Sand Analysis Report – R00114-1 (78 KB)

Sand Analysis Report – R00317-1 – This report shows a typical analysis with a very narrow particle distribution. (The grains are within a fairly close range.) Stren’s custom tailored product line is one of the few products on the market that allows maximum life with enhanced durability in these situations. Variable pore size devices typically have an extremely short life. Interesting illustration.

Sand Analysis Report – R011005-1 – This third example of a sand analysis report shows a much broader range of particles, though the damaging fraction is still in the the 50 – 250 micron range. Note the nodular (rounded) particles in the illustration. Though they are round in this sample, they become jagged and very abrasive when crushed between the barrel and the plunger or in an ESP application.
