Drilling fluid is an essential element of the drilling operations and has many functions. Some of these are wellbore cleaning, checking high formation pressures and corrosion protection, etc. This study aimed to determine the effects of multi-walled carbon nanotubes containing silisyum dioxide nanoparticles (SiO 2 NPsMWCNTs) were investigated on the rheological and filtration loss properties of Na-Bentonite water based drilling fluids (Na-WBDF).In this context SiO 2 NPs/MWCNTs was produced by chemical vapor deposition (CVD) method, characterized by X-ray Photoelectron Spectroscopy (XPS) and Scanning Electron Microscopy (SEM), and then added to Na-WBDF in different ratios (0.001 to 0.01% w/v). The rheological properties of the prepared drilling fluids such as plastic viscosity (PV), apparent viscosity (AV), yield point (YP), gel strength (10 s and 10 min) were performed by FANN viscometer, filtration loss and cake thickness were performed by American Petroleum Institute (API) liquid loss test equipment. Compared with spud drilling fluid; SiO 2 NPs/MWCNTs increased the PV value of Na-WBDF by 71.4%, AV value by 51.9%, YP value by 44%, 10 s and 10 min by 25% and 33.3% respectively, and decreased filtration loss value by 13.8%; At the same time, the value of cake thickness increased by 11%.

“…It is possible to come across some studies in the literature where nanomaterials are used as drilling mud additives. [5][6][7][8][9][10][11][12] Özkan et al, 13 stated that as a result of their studies in which they added graphene, graphene oxide and AuNPS/GO to drilling mud, both rheological and filtration properties of drilling mud were improved. In the study conducted by Özkan et al, 14 they examined the impact of functionalized zinc oxide nanoparticle material on multi-walled carbon nanotube (MWCNT) and water-based drilling mud.…”

We investigateed the effect of AgNPs@AuNPs/GO on the rheological and filtration properties of sodium-bentonite water based drilling muds (Na-bentonite WBDM) and compared the possible effects of graphene, graphene oxide (GO), and graphene oxide functionalized with gold nanoparticles (AuNPs/GO) on Na-bentonite WBDM. Graphene, AuNPs, AgNPs, GO, AuNPs/GO, and AgNPs@AuNPs/GO were initially synthesized, and subsequently subjected to scanning electron microscopy, tranmission electron microscopy, energy-dispersive X-ray analysis, reflection absoprtion infrared spectroscopy, and X-ray photoelectron spectroscopy characterization. At a rate of 0.0005% to 0.01% (w/v), synthesized and described nanoparticles were added to Na-bentonite WBDM. Rheological and filtration loss analyses of the nanomaterial-containing Na-bentonite WBDM were then performed following American Petroleum Institute Standards. According to the study’s findings, adding graphene and AgNPs/GO to drilling mud at varying rates did not have any influence on PV values when compared to spud mud; however, adding GO and AgNPs@AuNPs/GO had a positive effect of 67% and 33%. Furthermore, the addition of graphene, GO, AuNPs/GO, and AgNPs@AuNPs/GO increased the AV values by 17.6%, 44%, 18.75%, 26%, YP values; by 44.4%, 44%, 30%, 22%, 10 s values; by 55.5%, 33%, 30%, 66.6%, 10 min values; by 30.7%, 43%, 42%, 46%, filtration loss values; by 10%, 9.52%, 8.4%, 3.84%.

“…3 Therefore; It has been observed that the properties of drilling muds are improved by adding nano and micro-sized materials. [4][5][6][7][8][9][10][11][12] Özkan et al (2021), 13 when they investigated the effect of multi-walled carbon nano tube functionalized with zinc oxide nanoparticle material on water-based drilling mud, in their study, drilling mud with the addition of ZnONPs/MWCNTs; the plastic viscosity value increased by 42.8%, the apparent viscosity value increased by 31.6%, the yield point value increased by 28%, the 10 s and 10 min values increased by 22% and 25%, the cake thickness value increased by 38.9%, and the filtration loss value decreased by 13.8%. Özkan, A., in (2020); 14 investigated the possible effects of multi-walled carbon nanotubes containing gold nanoparticles by adding them to water-based drilling mud at different rates.…”

We aimed to improve the rheological properties of water based drilling muds (WBDM) by graphene, graphene oxide (GO), and graphene oxide functionalized with gold nanoparticles (AuNPs/GO) at 0.0005-0.01 (% w/v) ratios. For this purpose, AuNPs, graphene, GO, and AuNPs/GO were first synthesized, and then characterized by scanning electron microscopy, tunneling electron microscopy, energy-dispersive X-ray analysis, reflection absorption infrared spectroscopy, and X-ray photoelectron spectroscopy. Synthesized and characterized nanomaterials were added to WBDM at a rate of 0.0005% to 0.01% (w/v), and finally, rheological and filtration loss analyzes of water based drilling muds containing nanomaterials were carried out according to American Petroleum Institute Standards. By using nanomaterials to improve the properties of water based drilling mud, plastic viscosity, apparent viscosity, yield point, and gel strength (10 s and 10 min), increased by 67%, 44%, 44%, 67% and 50%, respectively, and at the same time, the filtration loss value decreased by 14%.
