Special Issue Information

Dear Colleagues,

The exponential growth of the world's population has led to a higher demand for fossil fuels to meet energy needs. In this regard, nanotechnology is becoming a key player in incorporating advances that lead to an increase in productivity and reserves of crude oil and gas. Recent applications under field conditions have proven that nanoparticles and nanofluids can inhibit/remediate different formation damage mechanisms, increase well productivity, and enhance the oil and gas recovery. Therefore, the main objective of this Special Issue is to provide the last advances and applications under an industrially relevant environment of nanotechnology-based solutions focused on productivity improvement and enhanced oil recovery (EOR) to face the current challenges of the oil and gas industry.

The main objective of this Special Issue is to provide novel, original, and high-quality articles as powerful tools for readers of Nanomaterials, the scientific community, and members of the oil and gas industry. Original research and review articles are welcome for this issue.

Topics that will be considered for this Special Issue include but are not limited to the following:

  • EOR
  • EGR (enhanced gas recovery)
  • Formation damage
  • IOR (improved oil recovery) and well productivity
  • Unconventional resources
  • Surface and/or Interface phenomena
  • Microfluidic
  • Nanofluids/nanoparticles

Development of Nanofluids for the Inhibition of Formation Damage Caused by Fines Migration: Effect of the Interaction of Quaternary Amine (CTAB) and MgO Nanoparticles

Fines migration is a common problem in the oil and gas industry that causes a decrease in productivity. In this sense, the main objective of this study is to develop nanocomposites based on the interaction of quaternary amine (hexadecyltrimethylammonium bromide—CTAB) and MgO to enhance the capacity of retention of fine particles in the porous medium. MgO nanoparticles were synthesized by the sol–gel method using Mg(NO3)2·6H2O as a precursor. Nanoparticles were characterized by dynamic light scattering (DLS), the point of zero charge (pHpzc), thermogravimetric analysis, and Fourier transform infrared spectroscopy (FT-IR). Different nanoparticle sizes of 11.4, 42.8, and 86.2 nm were obtained, which were used for preparing two system nanofluids. These systems were evaluated in the inhibition of fines migration: in the system I MgO nanoparticles were dispersed in a CTAB-containing aqueous solution, and system II consists of a nanocomposite of CTAB adsorbed onto MgO nanoparticles. The fines retention tests were performed using Ottawa sand 20/40 packed beds and fine particles suspensions at concentrations of 0.2% in a mass fraction in deionized water. Individual and combined effects of nanoparticles and CTAB were evaluated in different treatment dosages. The analysis of the interactions between the CTAB and the MgO nanoparticles was carried out through batch-mode adsorption and desorption tests. The best treatment in the system I was selected according to the fines retention capacity and optimized through a simplex-centroid mixture design for mass fractions from 0.0% to 2.0% of both CTAB and MgO nanoparticles. This statistical analysis shows that the optimal concentration of these components is reached for a mass fraction of 0.73% of MgO nanoparticles and 0.74% in mass fraction of CTAB, where the retention capacity of the porous medium increases from 0.02 to 0.39 mg·L−1. Based on the experimental results, the nanofluids combining both components showed higher retention of fines than the systems treated only with CTAB or with MgO nanoparticles, with efficiencies up to 400% higher in the system I and higher up to 600% in the system II. To evaluate the best performance treatment under reservoir conditions, there were developed core flooding tests at fixed overburden pressure of 34.5 MPa, pore pressure at 6.9 MPa and system temperature at 93 °C. Obtaining critical rate increases in 142.8%, and 144.4% for water and oil flow in the presence of the nanofluid. In this sense, this work offers a new alternative for the injection of nanocomposites as a treatment for the problem of fines migration to optimize the productivity of oil and gas wells. Full article
