New method accurately analyzes PHPA's in muds - OSTI.GOV

A recently introduced test method provides an accurate, quantitative measure of partially hydrolyzed polyacrylamides (PHPA's) used as clay encapsulators in drilling fluids. A field procedure has been developed that doesn't have the operator-centered inconsistencies that affect the previously used method.

METHOD AIDS CALCULATION OF PHPA DEPLETION RATES

One method involves maintaining approximately 1.5 lb/bbl PHPA (by filtrate analysis) in the drilling fluid and increasing this level only in response to upward movements in the PHPA variation curve.

A quantitative determination of phosphonate phosphorus in

A new method is described for the quantitative determination of naturally occurring aminophosphonates. Samples are treated sequentially with hydrochloric acid and alkaline phosphatase to convert esters to inorganic phosphate without destruction of phosphonates. The difference between inorganic phosphate and total phosphorus is then a measure of phosphonate phosphorus.
