<p>The unidealized of physical and rheological mud can occured when drilling on rock layers with high salt concentrations. It is therefore necessary to add an additive to balance the effect of the salt. The aims of this study is to see the effect of salt addition on various temperature drilling mud.</p><p>This research will use two types of mud with different oil-water ratio. The drilling mud will be divided into four compositions, ie LA, LB, LC, and LD. LA and LC compositions have an oil-water ratio of 80% oil and 20% fresh water. While LB and LD compositions have oil-water ratio of 75% oil and 25% fresh water. Then the study was conducted at various temperatures, ie 80 °F, 130 °F, 180 °F, 230 °F, 280 °F, and 330 °F. After observing of the physical properties and rheology of drilling mud, it was found that the effect of adding salt NaCl can improve the physical and rheological properties of mud such as density, viscosity, gel strengh, mud cake, and solid content. Conversely, the effect of adding NaCl salt may reduce the nature of electrical stability. While the increasing of the temperature can reduce the physical and rheological properties of mud and on the contrary the loss of water and mud cake will increase.</p>

Stable emulsions contained in oil sludge make it difficult to conduct. The physical properties of oil sludge usually vary widely and depend on the oil's own viscosity, temperature, oil-water ratio. Therefore, emulsions being dispersed systems under certain conditions have specific properties i.e. they are non-Newtonian liquids. Heavy oil and oil sludge are diluted with hydrocarbons, more often, gas condensate, which reduces the viscosity, density and other rheological parameters of high-sulfur oil.

Hydroxyethyl cellulose (HEC) is widely used in water-base drilling fluid as tackifier because of its good fluidity, stability, prop-carrying capacity, and good reservoir protection, while it has insufficient rheological property under higher temperature. In order to make use of its advantages and improve thermal stability, an innovative method that HEC was dissolved in the emulsion was proposed. Research indicated that compared with traditional water solution, the oil-water emulsion as solution could effectively improve the rheological properties and thermal stability. The oil-water ratio has an obvious effect on rheological properties. Firstly, with the decrease in the oil-water ratio, the apparent viscosity and shear stress were decreased; secondly, under constant oil-water ratio or temperature, the larger the shear rate, the lower the apparent viscosity, and the greater the shear strength; lastly under extremely low shear rate, HEC emulsion’s viscosity peaked at more than 50000 mPa·s, which can effectively solve the problem of sand carrying difficulty and being easy to form sand bed in horizontal well and high angle hole. In addition, the emulsifying stability was degradative with the increase in the oil-water ratio. The degradation was not obvious when the oil-water ratio was less than 30 : 70. On the contrary, the performance deteriorated drastically when the oil-water ratio was greater than 30 : 70. The separator liquid was more than 2 cm and was even about 1/3 when the oil-water was 50 : 50. On the basis of analysis of the experimental results, we can see that oil-water emulsion could effectively improve the rheological stability and thermal stability of HEC and the optimal oil-water ratio was 30 : 70. This study provided a new thought for application of HEC or other polymers in drilling fluid.

Stick-slip is kind of vibration which associated with drilling operation in around the bottom hole assembly (BHA) due to the small clearance between drill string & the open hole and due to the eccentric rotating of string. This research presents results of specific experimental study that was run by using two types of drilling mud (Fresh water Bentonite & Polymer), with/without Nanoparticle size materials of MgO in various ratios and computes the rheological properties of mud for each concentration [Yield point, plastic viscosity, Av, PH, filter loss (30 min), filter cake, Mud Cake Friction, Friction Factor]. These results then were used to find a clear effects of Nanoparticle drilling mud rheology on stick - slip strength by several perspectives through a special “Torque and Drag” software which simulate the torque amount expected on BHA during drilling a vertical well in different conditions using real drilling string design that usually used in Iraqi oil fields. Thus to mitigate or to prevent stick–slip and cure the sequence events that could happen to both of drilling string and the well, i.e. Bit/BHA wear, pipe sticking, borehole instability and low Rate of penetration. Our study concluded that there are good reduction in the torque from (2031lb-ft) to (1823lb-ft) using polymer mud and torque reduction from (4000lb-ft) to (3450lb-ft) using Fresh Water Bentonite, these results do not include any breaking in the satisfactory range of other mud rheology.

   The chemical additives used to enhance the properties of drilling mud cause damage to humans and the environment. Therefore, it is necessary to search for alternative additives to add them to the drilling mud. Thus, this study investigates the effects of pomegranate peel and grape seed powders as natural waste when added to un-weighted water-based mud. The test includes measurements of the rheological properties and filtration, as well as the alkanity and density of the drilling mud. The results showed a decrease in PH values ​​with an increase in the concentrations of pomegranate peel or grapeseed, and a decrease in mud density with an increase in powders of pomegranate peel and grape seed concentrations that resulted from the formation of foam. The rheological properties appeared with increasing except for the plastic viscosity. Grape seed powders reduce the filter cake thickness required to solve drilling problems caused by an increase in the mud cake thickness. From the laboratory results, it's possible to use powders of pomegranate peel and grape seed as additives to reduce plastic viscosity and filtrate volume.

The function of drilling mud is determined by the chemical composition and physical properties of the mud. Errors in controlling the physical properties of mud will cause failure which can lead to drilling problems (hole problems) and ultimately result in huge losses. Viscosity is an essential part of the rheological properties of drilling fluids. Measurement of the rheological properties of drilling fluids is important considering the effectiveness of cutting removal is a direct function of viscosity. In the petroleum engineering laboratory the determination of viscosity of drilling mud is usually done using Marsh Funnel. The research aims to compare the results of the determination of viscosity using marsh funnel and video-based viscosimeter assisted by software tracker. The sample in this study was drilling mud made from aquadest and bentonite with additives added. The experiment was carried out five times with different drilling mud compositions. Sample I made from bentonite plus 0.5 gram additive spersene. Sample II made from bentonite plus spersene aditive 1 gram, Sample III made from bentonite plus aditive CMC 0.5 gram.

Abstract Pickering emulsions have attracted extensive attention due to their good properties including easy to manufacture, high stability, and superparamagnetic response. To improve the emulsifying transportation of crude oil, a Pickering emulsion of crude oil and water stabilized by Fe3O4 nanoparticles was prepared and its rheological properties were tested in this research. It was found that the particle size of dispersion droplet polymerization group in stable crude oil Pickering emulsion is negatively correlated with solid content and water content, and the equilibrium apparent viscosity {\mu }_{\text{ap}} of emulsion follows the power law fluid equation. Besides, this kind of Pickering emulsion has higher elasticity of interface membrane, which means by adding functional particles, it obtains good dynamic stability, and thus, has a great application property in crude oil industry.
