“…The filter cake obtained from the HPHT filter press was examined with a MIRA3 (TESCAN) field emission scanning electron microscope (FESEM) equipped with a Schottky Field Emission electron gun in order to image the cluster of nanocomposites on the surface of the filter cake. 46 The filter cake, acting as a substrate, was completely dried. Because the ZnO nanoparticles present on its surface were nonconductive, they required gold coating for almost 1 min to provide a conducting surface necessary to interact with the bombarding electron beam to obtain a high-quality image.…”

For the successful cementing operation of petroleum wells, the design of cement slurry plays a crucial role. Cement slurry must address the requirements of higher compressive strength; lower fluid loss; durability; and high-pressure, high-temperature (HPHT) challenges. A large number of chemical additives in cement slurry affects the required rheological properties; therefore, the development of multifunctional additives is desirable. In the present study, this problem has been addressed with the use of a single polymeric nanocomposite additive to address multiple requirements. A novel tetrapolymer nanocomposite (TPN) was synthesized in the laboratory by in situ polymerization in the presence of zinc oxide nanoparticles. Four monomers, namely acrylamide, 2-acrylamido-2-methylpropanesulfonic acid, vinyl phosphonic acid, and N-[3-(dimethylamino)propyl] methacrylamide, were selected for the in situ polymerization reaction. The synthesized product was characterized using 1H NMR, FTIR, and TGA techniques. Laboratory-synthesized TPN was mixed in varying concentrations in the cement slurry as an additive. The performance of the enhanced cement slurry was then evaluated by performing compressive strength analysis and a filtration test using an ultrasonic cement analyzer and an HPHT filter press, respectively. These experimental analyses show that the addition of the TPN improved the compressive strength of the cement slurry and, at the same time, abbreviated the fluid loss, which is desired for efficient cementing operation. With the addition of 1.0% by weight of cement (BWOC) of TPN, the compressive strength increased by ∼136% compared with base cement. Additionally, this small dosage also reduced HPHT fluid loss by ∼67%. This experimental investigation shows that the novel TPN additive is capable of improving the efficacy of oil-well cement slurry at high-temperature conditions without compromising on thickening time because the additive also improved the waiting-on-cement time for HPHT conditions.

“…Thus, we aimed for thin and impermeable mud cakes that can prevent mud filtration and do not incur wellbore instability problems. 114 The large deposits of mud additives on the wellbore wall could trigger wellbore issues, leading to high workover and drilling time. The mud-cake thickness slightly increases to 0.44 in.…”

Toward Improvement of Water-Based Drilling Mud via Zirconia Nanoparticle/API Bentonite Material

Enhanced rheological and mud-filtrate loss characteristics of drilling muds are key to a successful drilling operation. Zirconium dioxide (ZrO2)/clay material (ZCNC) was synthesized using ultrasonication and characterized via scanning electron microscopy (SEM), X-ray diffraction, and Fourier-transform infrared spectroscopy. Moreover, the zeta potential of pristine zirconia and ZCNC was evaluated in distilled water to examine the stability of the colloidal material. Zeta potential measurements revealed that adding ZCNC to conventional water-based mud (WBM) exhibited a zeta potential similar to bentonite with very minute changes. Moreover, SEM revealed that zirconia nanoparticles formed a uniform layer on the bentonite surface. For the WBM, rheology and American Petroleum Institute (API) mud-filtrate loss are generally controlled using polymers, and these properties could also be improved by adding a minute concentration of synthesized ZCNC. Incorporating nanoparticles into the bentonite layer might augment the colloidal behavior of drilling mud and improve the rheological properties. The yield point was enhanced after adding 0.3 wt % of ZCNC. The gel strength improved by 60% after adding 0.6 wt % of ZCNC to a conventional WBM. A gradual increase in the ZCNC concentration to 0.6 wt % reduced the API mud-filtrate loss volume and minimized the mud-cake thickness. These characteristics could be attributed to coating bentonite layers with zirconia nanoparticles and plugging interparticle pore spaces in the mud system.

Surfactant flooding is a prolific enhanced oil recovery technique. It alters the rock fluid interfacial interactions between reservoir fluids and rocks. However, a pair of impeding factors often limit the economic viability of the process and need to be optimized. The first is the surfactant loss on the adsorbent surface due to adsorption making it a potential environmental problem. The second is the Critical Micelle Concentration (CMC) which governs the amount of surfactant pumped. This study aimed to minimize the surfactant loss and the CMC, thereby optimizing the flooding efficiency and reducing the environmental concerns for nanoparticle applications. To achieve this, Silicon Carbide nanoparticles (SCN) were employed as additives to the surfactant solution. It was observed that the use of SCN reduces the surfactant adsorption by as much as 44 % and the critical micelle concentration by 14 %. The studies also observed that the concentration of SCN required to get these results is dramatically (more than 25 times) lower than previously reported literature on other nanoparticles. To adsorption isotherm studies provide an insight into the type of adsorption taking place. The adsorption isotherm follows the Langmuir model.
