10407 Compatibility of Tetrakis (Hydroxymethyl) Phosphonium Sulfate (THPS) and Ammonium Bisulfate (ABS)

Product Number: 51300-10407-SG
ISBN: 10407 2010 CP
Author: Jennifer Moore, Vic Keasler and Brian Bennett
Publication Date: 2010
$20.00

In this paper the compatibility of the biocide tetrakis(hydroxymethyl) phosphonium sulfate (THPS) and the oxygen scavenger ammonium bisulfite (ABS) were explored.  Performance testing of both the biocide in the presence of the oxygen scavenger and the oxygen scavenger in the presence of biocide are reported.

Secondary oil production involves the injection of water into the reservoir, generally known as water flooding, to increase the reservoir pressure to its initial levels, to maximize the oil recovery out of the ground. The injected water flows through the formation to flush the oil from the formation into the production system. Injection systems are the portion of the field that is responsible for injecting the water into the formation. Source of water may be lake, river or sea water.

Tetrakis(hydroxymethyl)-phosphonium Sulfate (THPS) is a very common active ingredient in oil and gas biocides. While product labels provide broad guidelines application dosing the lowest effective dose of THPS is difficult to determine. Site water chemistry and bacteria biology variability will affect the dose need to achieve the desired level of bacteria population control. For these reasons biocide dose response studies are commonly conducted on solutions containing bacteria to determine the effect of treatments before application.
