Nevertheless, the scope of the more tips here function was not prolonged to the feasible dynamic effects on the sand strength reduction and sand failure. Determine one exhibits the SEM images and EDAX scans of the two cores prior to fluid injection and saturation. The SEM images show that each rock cores are composed of well-sorted, subrounded quartz minerals. The EDAX scans validate this mineralogical description as evidenced by the higher traces of Si and O2, which are the significant factors in quartz mineral . The injection and saturating fluid was well prepared by diluting a amount of various salts in deionized drinking water. The salts utilized and their concentrations are provided in Desk 1. The brine was filtered through a forty five um filter paper just before each use. The use of filtered brine ensured no extraneous fines had been released to the cores the brine also served to stabilize any clay minerals that may well currently be present in the cores. A stock of 5% phosphonate scale inhibitor answer was prepared by diluting 12.50 g of the SI in 250 mL of brine. Right away after removing the two cores from the brine in stage 1, every was set in a individual Hassler-type main holder which was then hooked up to a independent core flood rig. The cores have been saturated individually by flowing brine through them for 6 h at a circulation price of 1 mL/min. Low flow charge ensured that the interstitial velocity of circulation was laminar ample to preserve fines from clay minerals stabilized even though extended saturation time ensured that the cores ended up totally saturated. The porosities of the two cores have been measured utilizing lithium tracer technique. The method for employing this porosity measurement strategy can be identified in other places in the literature . Lithium is an inert metallic the use of lithium tracer strategy therefore ensured that there was no interaction—physical or chemical—between the cores and the lithium answer. The permeabilities of the two cores had been also calculated employing flow prices of 1, four, three, two, and one mL/min in sequence. Effluent samples were collected from each circulation program in the course of the maximum circulation price regime and their grain dimension distributions ended up measured using Malvern Mastersizer 2000. Once more, minimal circulation price was utilised in purchase to eliminate any attainable large movement-fee outcomes. The coreholders™ inlet and outlet valves had been then shut down and the cores remaining right away to enable for a for a longer time interaction time between the main and SI. Brine was continuously injected into the second core”overnight. The scale inhibitor was then flushed out of Main A using the filtered brine at a circulation price of .25 mL/min. Effluent samples ended up gathered from inhibitor flowback from Main A and brine injection from Core B. The grain dimensions distributions of the effluent samples ended up measured making use of Malvern Mastersizer 2000. This was an indication that the brine 1000413-72-8 had no detrimental actual physical or chemical consequences on the grain cloth that could have induced the deterioration of grain-tograin binding and subsequent grain release and physical appearance in the brine effluents.
