Drilling fluid is an important part of rotary drilling due to its ability to divert rock chips to the surface, preventing forming fluids from entering the borehole. Typically, some chemicals and nanomaterials were used to optimize the associated properties of drilling fluids. This study focuses on the formulation of nanobiodegradable drilling fluids from wheat powder in various concentrations (0.5, 1 and 2% by weight) and particle sizes (nano-size 75, 150, 300 and 600 mm). The wheat nanobiopolymer was prepared using spherical milling techniques and characterized using SEM, FTIR, DLS, TGA and DSC. The effect of wheat was investigated by performing several experimental tests of rheological and filtration measurements under different temperature conditions of 25, 50 and 70 °C. The results obtained showed that wheat powder of all different sizes has an effect on rheological properties including plastic viscosity, yield strength and gel strength. These properties increase with increasing size and concentration of wheat particles. This effect is more dominant at higher temperatures, e.g. 50 and 70 °C. In addition, the biodegradable additive used made it possible to reduce the thickness of the filter cake by 50% from 5 to 2.5 mm using sizes of 75 and 150 mm and a concentration of 2% by weight. Due to wheat at a size of 150 mm and a concentration of 2 % by weight. the filtration rate of drilling fluid was also significantly reduced from 19.5 to 11.5 cm3.

Drilling fluid is a crucial part of the rotary drilling operation due to its functions in carrying rock cuttings to the surface and preventing formation fluids to enter the wellbore. Conventionally, several chemicals and nanomaterials were applied to optimize the related properties of the drilling fluids. This study focuses on formulating nano-biodegradable drilling fluids from wheat powder at different concentrations (0.5, 1 and 2 wt.%) and particle sizes (nano-size, 75, 150, 300 and 600 m). The nano-biopolymer of wheat was prepared using ball milling technique and characterized using SEM, FTIR, DLS, TGA and DSC. The impact of the wheat was investigated conducting several experimental tests of rheological and filtration measurements under different temperature conditions of 25, 50 and 70 °C. The obtained results showed that wheat powder at all different sizes has an impact on the rheological properties including plastic viscosity, yield point and gel strength. These properties are increased with increasing the size and concentration of the wheat particles. This effect is more dominant with higher temperature, such as 50 and 70 °C. In addition, the used biodegradable additive enabled to reduce the thickness of the filter cake by 50% from 5 to 2.5 mm using 75 and 150 m sizes and 2 wt.% concentrations. The filtration rate of the drilling fluid is also highly reduced from 19.5 to 11.5 cm3 under the influence of wheat at 150 m size and 2 wt.% concentration.

Thesis summary
The demand for oil and gas has increases, as it has the need for cost-effective means of getting them. Yet, the drilling procedure should be safe, environmentally friendly, and cost-effective. A large of issues develop during the drilling and production processes in the petroleum industry. When fluids in the borehole flow, such as drilling fluid or completion fluid, may be lost underground to the subsurface formation. Fluid loss is thus recognized as a crucial problem that happens during the majority of drilling procedures. Fluid loss becomes more essential when the difference pressure and circulation rate between the flowing fluid and the wellbore increase. Nanotechnology has the potential to offer many big advancements, notably in overcoming several obstacles in the oil and gas business, if used in drilling technology. The combination of drilling fluid techniques and nanomaterial studies has led to the discovery of the distinctive properties and role of nano-additives in drilling fluids, such as the improvement of filtration, increased removal of cuttings, reduced friction, enhanced stability of wellbore formations, and higher speed, safety, and quality of drilling operations in complex conditions. Nanomaterials have shown positive impact for the exploration of oil and gas applications in terms of speed and success rates, as well as ensuring safer drilling operations. The addition of nanomaterials, such as nanoparticles, to drilling fluids improves their rheological and filtration characteristics. The aim of this experiment is to lower the fluid by analyzing the rheological and filtration behavior by using nano sized particles in 4 different sizes such as 75,150,300,600 microns and wheat sized nano particle.

Effect of particle size of wheat on the rheological and filtration properties of the drilling fluid
The student presented his bachelor's thesis in a MS PowerPoint presentation.
The reviews of both supervisor (Dr. J. Ali) and reviewer (prof. H. Mansurbeg) were handled
by their authors. The supervisor suggested a grade A, while the reviewer pointed out some minor mistakes and suggested grade B.
In the discussion of the committee members, Dr. J. Ali asked a question whether student was measuring only plastic viscosity and what is the problem with the thick mud cake. Prof. Šráček inquired about the cost of the nanomaterial. Student answered sufficiently all of the above-mentioned questions.
In the public discussion, no question arose.
The committee agreed on an overall evaluation – grade A.
