“…When cement slurry samples with different amounts of Nano-silica were observed, the results showed that as the percentage of Nano-silica in the cement slurry increased, the fluid loss decreased (Thakkar et al, 2020). This was in agreement with later research by (Makwana et al, 2021) who in addition, included higher yield stress as an advantage of Nano silica addition to cement.…”

“…It also reduced the dimensions of the pores present and hence contributed to the reduction in permeability. Similar findings were reported by (Makwana et al, 2021;Nie et al, 2022;Thakkar et al, 2020). Mercury Intrusion Porosimetry (MIP) tests by (Ghafoori et al, 2020) showed that for mortars containing 6% Nano silica, the void volume proportion of gel pores and micropores increased in comparison with those of the control, and there was an overall reduction in the capillary macro pores.…”

“…Addition of Nano silica was reported to increase the compressive strength of cement (Makwana et al, 2021;Moslemi et al, 2014;Nie et al, 2022;Thakkar et al, 2020;Wang et al, 2020) . Research (Rzepka & Kȩdzierski, 2020) found that early compressive strength amounting to 3.5 MPa was achieved by slurries after times between approximately 7 h and 14 h. After 28 days of hydration, the compressive strength of the hardened cement stones had very high values up to 50 MPa (Rzepka & Kȩdzierski, 2020).…”

Purpose: This research was intended to evaluate Nano silica as an additive to improve the sulphate resistance of cement used in geothermal wells. Design/ Methodology/ Approach: Sulphate resistance was determined by measuring the longitudinal change in cement cube specimens that were cured in sodium sulphate solution for 21 days. Cube specimens with varied concentrations of Nano silica (0%, 0.3%, 0.6%, 0.9% and 1.2%) were used in the study. Five separate solutions were maintained at 23℃, 40℃, 65℃, 70℃ and 80℃ for 21 days. Final length measurements were taken and compared as a percentage of initial length measurements. Findings: Beyond 65℃, the sulphate resistance of cement improved for each percentage concentration of Nano silica replacement. Control specimens with 0% Nano silica had the most inferior performance at all temperatures. Higher concentrations of 1.2% and 0.6% Nano silica replacement gave the most resistance between 23℃ and 65℃. A lower concentration of 0.3% proved more suitable between 65℃ and 80℃. Research limitation: The results of the experiment indicate performance in low-temperature geothermal wells. Practical implications: The application of this additive can improve the durability and strength of the cement, reducing the potential for degradation due to exposure to sulphates. This can lead to a longer lifespan of the geothermal well, reducing maintenance costs and increasing its overall efficiency. Social implications: Improved cement designs that create longer-lasting cement sheaths can be developed from this research, thereby fostering geothermal energy development. The option to replace certain volumes of cement with Nano silica contributes to a reduction of the carbon footprint by minimising the demand for, and therefore the production of cement. Originality/ Value/ Novelty: Previous research that tested cement at high temperatures analysed mechanical resistance. This research examined the sulphate resistance of cement at high temperatures.

“…In recent years, nanomaterials have received extensive attention in the oilfields − due to the characteristics of small size, large specific surface area, wide sources, and low cost. After surface modification, the functional headgroups can be introduced onto the surface of nanoparticles, endowing nanoparticles with great application potentials in the oilfields, such as reducing injection pressure, enhancing oil recovery (EOR), and imbibition. − Especially in the imbibition process, some studies reported that the main factor of nanomaterial imbibition is the wettability reversal caused by nanoparticles.…”

Nanomaterials have been widely used in oilfields and have attracted more attention. At present, the introduction of nanofluids plays an important role in the imbibition of low-permeability reservoirs. However, the interfacial activity of nanofluids is usually low. There are few studies on the effect of ultralow interfacial tension (IFT) on nanofluid imbibition. In this work, nanofluids with ultralow oil–water IFT of 10–3 mN/m were screened. The core huff–puff imbibition and static imbibition experiments were carried out to study the role of ultralow IFT in imbibition recovery. The experimental results show that ultralow IFT can make the static imbibition of nanofluids reach equilibrium more quickly, but its performance in improving imbibition recovery is limited. The hydrogen nuclear magnetic resonance (HNMR) result illustrates the oil migration process of a huff–puff imbibition. Compared with the injection and production stages, the imbibition in the shut-in stage has a higher contribution to oil recovery. It is found that nanofluids with ultralow IFT have stronger wetting reversal ability at the initial stage by comparing the oil/water/solid three-phase contact angles of different systems. Finally, under the condition that the wetting reversal ability is almost the same, the ultralow IFT reduces the capillary effect and is not conducive to the process of imbibition.

This work used aqueous solution free radical polymerization to create polymers of 2‐acrylamide‐2‐methylpropane sulfonic acid, itaconic acid, and allyl polyoxyethylene ether as a high‐temperature resistant retarder (APMS/IA/APEG, from now on referred to as AIA). Gel permeation chromatography, fourier transform infrared (FTIR), proton nuclear magnetic resonance (1HNMR), and thermo‐gravimetric analysis (TG) were used to characterize their molecular structure and characteristics. Tests were conducted on the thickening time, rheological characteristics, and compressive strength of AIA in cement slurries. The cement slurry thickened for 276 min at 180°C during the test, and the cement stone's 24‐h compressive strength was consistently more than 20 MPa. The hydration products were analyzed using x‐ray diffractometer and scanning electron microscopy methods, which were then coupled with molecular dynamics simulations to elucidate the AIA retarding mechanism. When AIA is added to a cement slurry, it forms a chelate structure with Ca2+ and a strong adsorption layer on the surfaces of the cement particles. This stops the cement from hydrating. The AIA side chain, APEG, can wrap the active group in AIA at low temperatures. AIA exposes more adsorption groups because of the APEG chains stretching at higher temperatures. AIA can, therefore, be used for deep well operations at high temperatures.
