... Abstract This study investigates the effect of silica nanoparticles with different functional groups and sizes on CO 2 foam stabilization in synthetic seawater by analyzing both bulk-scale and bubble-scale behavior. The primary objective is to evaluate the surface characteristics of silica...

... techniques. These case studies demonstrate how the application of these techniques has resulted in tangible reductions in NPT, allowing previously problematic wells to be drilled more efficiently and safely. A key component of wellbore strengthening fluids is the incorporation of nanoparticles, which have...

... Abstract This paper presents the results acquired during first laboratory-scale chemical flooding evaluation for a giant waterflooded oilfield in Kazakhstan. A carefully-designed chemical flood recipe involves the injection of a mixture of surfactant and alkali/nanoparticles followed by polymer...

... charged assembled polyelectrolyte-complex (PEC) nanoparticles as a technique for targeted and controlled release of enzyme breakers. Our previous work ( Alhajeri et al. 2021 ) showed that positively charged PEC nanoparticles using the Polyethylenimine-Dextran Sulfate system can produce stable...

... assisted by nanoparticles for EOR in a heavy oilfield is presented in this paper. The extent to which the gas EOR optimization techniques can lower gas breakthrough while boosting oil recovery was investigated through a series of numerical simulations. The aim of this study is to model foam flooding...

... ≤ 30 μm), aragonite fines (size ≤ 5 μm), and calcite nanoparticles of three different sizes (15–40, 50, and 90 nm) were used for emulsion formation in brine–oil mixtures. CaCO 3 micron-sized fines (calcite and aragonite) and calcite nanoparticles were characterized by Scanning Electron Microscope (SEM...

... Abstract The present paper describes the development of unique chemistries for plugging and sealing water producing zones and binding produced sand in unconsolidated formations. This is achieved by tuning the surface chemistry of the nanoparticles to act as either conformance sealants...

... to synthesize fresh nano-materials. Based on the small partice size of NPs' (1-100) nm, the nanomaterial's optical, thermal, chemical and structural properties differ completly from those shown by either its atoms or bulk materials. Nanoparticles and surfactants assist each other stabilize and maintain stable...

... atoms and molecules. Based on the small partition size of NPs (1-100) nm, the optical, thermal, chemical and structural properties of the nanomaterial differ completely from those shown by either its atoms or bulk materials. It is also clear that surfactants contribute to the stability of nanoparticles...
