“…This polymer was assayed as LCM. [49] The product was fully characterized chemically, physically and thermally and its water swelling and sealing capacity was assayed. It was interesting to observe that this new hydrogel showed a percentage hydration of 1700 % after 4 hours of hydration acquiring a maximum hydration of 2300 % at 168 h. In order to use it as LCM, sand bed test as well as High Pressure and high temperature (HPHT) cell assays, were done, showing that this material was a good application for this aim.…”

Many new achievement developments for different industries have their origin in the basic science. Within the last years, this trend is gaining much attention since the interaction between both fields (scientific and industry) is increasing. This article presents some rational materials chemical modifications that were developed by the basic science and were, then, transferred to the productive sector. Conducting hydrophobic coatings for aerospace applications, hydrogels for the oil & gas industry as well as polymers for removal of heavy metal were some of the topics approached in the lab to solve industrial problems. Many times, nature is a great source of inspiration to produce new materials. In this sense, superhydrophobicity and superhydrophilicity (concepts closely related to our everyday life) were the bioinspiration for the development of membranes. These membranes were able to separate hydrocarbons and water, which found application in the treatment of subterranean water for oil & gas industry.

“…In the search of new materials with high hydrophilicity, a new hydrogel was obtained from acrylamide crosslinked with 1,3‐divinyltetramethyldisiloxane using as initiator system ammonium persulfate (APS) and N , N , N′ , N′ ‐tetramethyl ethylenediamine (TEMED) (Figure 6). This polymer was assayed as LCM [49] …”

“…10−13 Besides, another problem that gel can address is lost circulation (LC), which is a common issue during drilling operations. 14 Lost circulation is prone to happen in formations including pore throats, induced or natural fractures, and caverns. 15 Events such as a blowout may take place in severe situations.…”

The nanocomposite gel system has been successfully applied as a water shutoff agent to enhance oil recovery (EOR) or for plugging to control lost circulation events. In this study, the silica/polyacrylamide nanocomposite was synthesized via in situ free radical polymerization of acrylamide (AM) monomers in the presence of silica nanoparticles. The composite was cross-linked with polyethylenimine to prepare a high-strength hydrogel. The viscosity test was conducted to determine the gelation time of the gel. Rheological measurements and sand pack breakthrough pressure tests were carried out to measure the gel strength. Attenuated total reflectance-Fourier transform infrared (ATR-FTIR) and scanning electron microscopy (SEM) tests were adopted to characterize the structure and morphology of the gel. The results show that compared to polyacrylamide (PAM) gel, the gelation time of the nanocomposite gel will decrease with increasing gel elasticity modulus, and the breakthrough pressure of the nanocomposite gel is 29.82 MPa, which increased by 65%. As shown in the ATR-FTIR test, this can be attributed to the presence of multiple hydrogen bonds for the PAM molecule with both silica and quartz sand particles. In the composite gel, hydrogen bonding mainly forms between the O atoms of PAM and the H atom on the surface of silica, enhancing gel strength and elasticity modulus with more cross-linking density and less porosity. Moreover, H bonding between additional −NH 2 of PAM and quartz sand particles helps improve gel plugging pressure. However, in the silica and PAM mixture gel, the H bonding of silica occupies −NH 2 of PAM, which became unavailable to attach on the sand surface, reducing the breakthrough pressure by 30%, although it can enhance the rheological strength. This study suggests that in situ composite of silica in PAM can not only greatly improve gel rheological strength but also help maintain the strong adhesion of PAM molecules onto quartz sand, resulting in better plugging performance in the sand reservoir.
