“…Afolabi et al [50] evaluated the rheological properties of bentonite mud at three different concentrations (6.3 wt %, 13 wt % and 15 wt %) containing different concentrations of silica nanoparticles (0 wt %-1.5 wt %). They developed a new hyperbolic model to evaluate the rheological properties of the bentonite mud with and without silica nanoparticles.…”

Nanomaterials are engineered materials with at least one dimension in the range of 1-100 nm. Nanofluids-nanoscale colloidal suspensions containing various nanomaterials-have distinctive properties and offer unprecedented potential for various sectors such as the energy, cosmetic, aerospace and biomedical industries. Due to their unique physico-chemical properties, nanoparticles are considered as very good candidates for smart drilling fluid formulation, i.e., fluids with tailor-made rheological and filtration properties. However, due to the great risk of adapting new technologies, their application in oil and gas industry is not, to date, fully implemented. Over the last few years, several researchers have examined the use of various nanoparticles, from commercial to custom made particles, to formulate drilling fluids with enhanced properties that can withstand extreme downhole environments, particularly at high pressure and high temperature (HP/HT) conditions. This article summarizes the recent progress made on the use of nanoparticles as additives in drilling fluids in order to give such fluids optimal rheological and filtration characteristics, increase shale stability and achieve wellbore strengthening. Type, size and shape of nanoparticles, volumetric concentration, addition of different surfactants and application of an external magnetic field are factors that are critically evaluated and are discussed in this article. The results obtained from various studies show that nanoparticles have a great potential to be used as drilling fluid additives in order to overcome stern drilling problems. However, there are still challenges that should be addressed in order to take full advantage of the capabilities of such particles. Finally the paper identifies and discusses opportunities for future research.

“…A 2 2 (2-Level, 2-Factors) central composite design was used to create a statistical model to study the quadratic effects and interaction effects between the kelzan® xcd polymer and bentonite particles. MINITAB® 17 (PA, USA) statistical software was used in the design of experiment and statistical analysis of the experimental data [1] .…”

The experimental dataset in this article are for improved rheological properties and lubricity of Nigerian bentonite mud using Kelzan® xcd polymer and identifying it optimal combination. For this study, water base mud was formulated using a Nigerian bentonite and a statistical based method was used to analyze the rheological and lubricity properties of the drilling fluid, when enhanced with kelzan® xcd polymer. The significant and interaction level of these factors were closely observed on the mud properties test that were conducted. The use of response surface design was engaged to analyze the influence of bentonite quantity and the quantity of kelzan® xcd polymer on the lubricity and rheological properties of the mud. Minitab 17 (Minitab Inc. USA) was used for the response surface design. The p-values were used to determine which of the factors in the model are statistically significant, which was compared to α-level (0.05). The p-values for the quantity of kelzan® xcd polymer are 0, 0, and 0.007 for Apparent viscosity (cp), Yield point (Ib/100 ft^2), Plastic viscosity (cp) respectively. All these values are lesser than the α-level (0.05), which means that the effect of kelzan® xcd polymer is significant on the model. While the effect of Bentonite content and the interaction between Bentonite content and kelzan® xcd polymer are insignificant because their p-values are higher than the -level (0.05).

“…Decreased fluid velocity at the low side of the wall have been reported in numerous literatures to be the main cause of poor cuttings transportation with increasing hole-angle (Duan et al 2008;Ismail et al 2016;Ford et al 1990;Gavignet and Sobey 1989;Onuoha et al 2015). Gbadamosi et al (2018b), Hakim et al (2018), Elochukwu et al (2017), Afolabi et al (2017), Ismail et al (2016) and Piroozian et al (2012) all reported that the rheological and filtration properties of drilling fluids have significant contributions in determining the effectiveness of cuttings transportation. The rheological properties are often optimized to ensure that drilling fluid can function effectively and yet lessen the drilling cost.…”

Henna leaf extracts (HLE) was used to formulate henna water-based mud (HWBM) and its performance on cuttings transport efficiency (CTE) was compared with bentonite water-based mud (BWBM) and fresh water. Tests were conducted in a laboratory-scale flow-loop equipped with a 16-ft-long test section consisting of a concentric annulus outer casing (3.5-in. ID) and a static inner drill-pipe (2.4-in. OD) at hole-angles of 0°, 45°, 60°, 75° and 90° with annular fluid velocities (1.1, 1.54, 1.98 and 2.31 ft/s) using a cuttings size diameter of 1.0 mm. Experimental results showed that HWBM have better rheological and filtration properties before and after thermal aging tests than BWBM. Plastic viscosity (PV) was 7.4 cP for BWBM and 6.5 cP for HWBM. Apparent viscosity (AV) of BWBM was 12.7 cP and 13 cP for HWBM. The yield point (YP) of BWBM was 10.5 lb/100 ft 2 and 12.2 lb/100 ft 2 for HWBM, while high pressure high temperature (HPHT) filtrates volume of HWBM was increased by 70.4% from 5.4 to 9.2 ml but, that of BWBM was increased by 94.4% from 7.1 to 13.8 ml. After heating, the PV of BWBM and HWBM decreased by 6.76% and 1.54%, respectively. The YP of BWBM and HWBM was reduced by 21% and 4.1%, respectively. 45° was the most challenging hole-angle, which needs attention while preparing drilling mud. The findings reported in this study could open new areas of research, in particular HLE additive to boost the drilling industry.
