“…There are a lot of factors including the type of the drilling fluid additives, well condition, and formation properties that were encountered during the drilling operation which might cause adverse impact on the performance of the drilling fluid and the well condition. This issue is directly associated with the thermal stability of many additives, which leads to improper properties by altering the performance of the designed drilling fluid additives [3][4][5][6][7][8]. In addition, the alteration in the physical properties of the drilling additives as the particle size is directly affected by the viscosity and the packing of the solids in mud and filter cake layer [9].…”

The drilling fluid must be designed through a comprehensive process to select the right additives, and then must passed through different API standard evaluation processes to ensure the quality. However, the contamination of the drilling fluid with the drilled cuttings caused a significant alteration in the drilling fluid and sealing properties of the drilling fluid. Therefore, many studies have been conducted to identify the effect of different cuttings on the drilling fluid properties. The current work emphasized on the impact of four different cuttings (quartz sandstone, Argillaceous sandstone, Siliceous claystone, and Kaolinitic claystone). The utilized cuttings in this work were selected carefully from different sandstone types to have varied clay content ranged from 0 to 70%. The selected cuttings were prepared and then characterized in term of their mineral composition and particle size distribution. In order to accomplish the objective of this work, the base mud contains zero cutting concentration, after that, an additional four drilling fluid samples were prepared by adding the prepared cuttings in two different concentrations include 5 wt.% and 10 wt.%. Several indispensable tests were conducted to investigate the impact of the added cutting on the rheological properties, filtration performance, filter cake properties, and other primary properties such as the drilling fluid density and pH. The results exhibited that the fluctuation of fluid properties was governed by two factors, one was the cutting concertation and the other was the clay content. Filter cake thickness showed high sensitivity at the low cutting concentration while the other properties were mostly in the acceptable range. On the other hand, at higher concentration, the results fall down into two clusters: cuttings with clay content ranging from 0 to 50% (quartz sandstone cuttings, Argillaceous sandstone, and Siliceous claystone) and cuttings with clay content higher than 50% (Kaolinitic claystone) as shown in details in the result section of this work. This works highlight the important of considering the cutting impact on the drilling fluid properties which ultimately impact the whole drilling operations.

“…Therefore, it is necessary to strictly control the rheological properties of drilling fluid to avoid the increase in equivalent circulating density (ECD) and the phenomenon of pressure leakage in the drilling process. It is also important to ensure that the drilling fluid can avoid surge pressure caused by tripping, which is conducive to wellbore stability [ 10 ]. In addition to improving the rheological properties of high-temperature and high-density drilling fluids, it is also important to control their filtration loss, which contributes significantly to wellbore stability and reservoir protection.…”

The environment-friendly water-based drilling fluid system developed for the petroleum development industry cannot successfully withstand temperatures up to 180 °C, and most high temperature-resistant additives with sulfonic acid groups that have been successfully applied to water-based drilling fluid are not good for environmental protection. In order to solve the above technical problems, a non-sulfonated filtrate reducer and viscosity reducer with resistance to high temperature were prepared by using humic acid, lignin and a multifunctional monomer as raw materials. In laboratory experiments, the molecular weights of the FLO-H filtrate reducer and the VR-H viscosity reducer were 5.45 × 105 g/mol and 8.51 × 103 g/mol, respectively, and all of them showed good high-temperature resistance. The API filtration loss of the bentonite-base slurry with 3.0 wt% FLO-H was only 6.2 mL, which indicated that FLO-H had a prominent reduction in filtration loss after aging at high temperature. When the dosage of VR-H was 1.0 wt%, the plastic viscosity of the water-based drilling fluid after aging at 200 °C decreased from 71 mPa·s to 55 mPa·s, which provided excellent dispersion and dilution. The high-temperature and high-density water-based drilling fluid containing the FLO-H filtrate reducer and the VR-H viscosity reducer had good suspension stability and low filtration performance at the high temperature of 200 °C, which can meet the requirements of high-temperature deep well drilling.

“…Most of the bentonite clay deposits found in the country do not possess the rheological properties stipulated by the American Petroleum Institute (API). They have poor swelling capacity compared to the imported sodium-based bentonite clay (Agwu et al 2015;Arabi et al 2017Arabi et al , 2018Dewu et al 2011). API stipulates that the minimum viscosity requirement for usage of any bentonite clay should be 30 cP at 600 rpm (API 1993).…”

“…A lot of researches have been conducted on the improvement to Nigerian bentonite clay for oil and gas drilling operations. It was observed that the approach used did not improve the mud viscosity much except in cases where viscosifiers were added to the mud (Agwu et al 2016 ; Apugo-Nwosu et al 2011 ; Arabi et al 2017 , 2018 ; Arinkoola et al 2019 ; Falode et al 2007 ; Omole et al 1989 ). Hence, the industry still relies on imported bentonite clay.…”

In less than a decade, there have been two global meltdowns of crude oil price and the latest was caused by the spread of coronavirus disease (COVID-19) in 2020. This is expected to have a negative impact on the global economy, especially on those countries that depend more on the revenue from sales of crude oil. One of the measures that can be taken to survive this kind of situation in the future is to reduce the unit technical cost for producing a barrel of oil by using locally available materials. This research investigated a local clay sourced from Ropp in Plateau State, Nigeria, by considering its rheological characteristics and economic implications of using it for partial to total substitution of imported bentonite clay for oil and gas drilling operations. The local clay was termed as Ropp bentonite clay (RBC). Various spud mud samples were prepared by dispersing a mixture of imported bentonite clay (IBC) and RBC (0–100%) in 350 ml of water. Certain quantity (0–1 g) of polyacrylamide cellulose was added to the mud samples before rheological and physical properties were determined using the standard API procedure. An economic model was built to determine the cost implications of using any of the mud formulations at different consumption rates. The results show that IBC–RBC blend in the right proportion could save Nigeria 12 to 36% of the cost of bentonite clay used to drill wells in the country.
