Application of scale inhibitors in oil and gas production is aimed at mitigating scale blockage during production. Many experimental, mathematical, and numerical simulation modeling works have been carried out to evaluate behavior, performance, and interaction of the scale inhibitor chemicals within porous media in relation to their efficiency in solving scale problem. However, the mechanisms underpinning scale inhibitors performance are not well published. Some research works have shown theoretically that not all scale inhibitors pumped into the formation adsorb onto the formation rock. Some of the inhibitors may adsorb on produced loose sand grains or colloidal fine sand particles which float and flow within the pore spaces along with the scale inhibitor mostly in unconsolidated reservoirs This paper provides a review of research work on the effect of produced loose sand or colloidal fine particles flow on polyphosphonates and polyphosphinopolymer scale inhibitors performances during crude production.

“…With respect to many reports that the use of scale inhibitor squeeze chemicals is a common and efficient method of dealing with scaling problems in oilwells, the criteria for potential scale inhibitor squeeze treatment necessitates retention of a greater percentage of the squeezed inhibitor on the adsorbent either through adsorption or precipitation and steady rate release above minimum inhibitor concentration (MIC) for a long period of time (Ghosh et al, 2012). Retention of a greater percentage of the squeezed inhibitor for a long period of time will require a reliable squeeze plan to be performed.…”

Scale inhibitors are deployed as preventive and rejuvenation operation in oil and gas industry when production operations are under threat or menace of scale blockage. The application of scale inhibitors is carried out through a method known as squeezing. In general, the squeeze process is governed by inhibitor-rock interaction which is described by adsorption/desorption isotherm. Most reservoirs produce loose sand grains or fine sand which float and flow within the pore spaces along with the squeezed scale inhibitors. Hypothetical reports have shown that not all scale inhibitors pumped into the formation adsorb onto the formation rock. A number of factors (irreversible adsorption, pH changes, competing ions, concentration and temperature) have been considered to affect the adsorption and return profile of these scale inhibitors. This review work examines the performances of most common scale inhibitors used in the oil and gas production activities, theoretical application in reservoirs and how loose fine sand grains affect the adsorption and desorption characteristics of squeezed scale inhibitors. Additionally, presented were overviews of previous reports on fine sand production and migration of fine sands through formation pores in reservoirs.

The inhibition efficiency of polycarboxylic acid will decrease due to the weak acidity of carboxyl group in high Ca 2+ geothermal circulating water. To solve this problem, we synthesized a novel carboxyl terpolymer (MA-AEO-7/SMAS/MA) with adipate polyoxyethylene ether maleate monoester (MA-AEO-7), sodium methacrylate sulfonate (SMAS) and maleic acid (MA). Its inhibition efficiency and mechanism were investigated at high Ca 2+ . The results indicated that the inhibition efficiency of MA-AEO-7/SMAS/MA was 96.84% for CaCO 3 at the monomeric ratio of 0.5:1:1 and a dosage of 12 mg L À1 . The X-ray diffraction and scanning electron microscope results of CaCO 3 scale showed that the presence of MA-AEO-7/SMAS/MA converted CaCO 3 calcite to vaterite with smaller particle size. The molecular dynamics and density functional theory calculations indicated that the increased solubility of MA-AEO-7/SMAS/MA and the carboxylic acidity in MA-AEO-7/SMAS/MA enhanced the Ca 2+ chelating properties. The electrostatic repulsion between the sulfonic acid groups made MA-AEO-7/SMAS/MA exhibit good dispersion properties. These findings explained why the inhibition efficiency of MA-AEO-7/SMAS/MA remained above 80% at Ca 2+ concentration of 1500 mg L À1 , exceeding the 30%-50% of the three commercial scale inhibitors.This study provides practical insight for the development of scale inhibitors suitable for high Ca 2+ geothermal circulating water.
