“…The rheological and filtration properties of drilling fluids were evaluated by a Fann viscometer (Model 35, Fann Instruments Company, Houston, Texas, USA) and the dead weight filter press apparatus (Fann Instruments Company, Houston, Texas, USA) having filter paper of 9 cm diameter. The flow model of the IMME (O/W) emulsion mud was confirmed by obtaining a relation between the shear stress versus the shear rate and viscosity versus shear rate on the cartesian coordinate system with the aid of Anton Paar rheometer (Anton Paar Analytical Instrument Company, Ashland, Virginia, USA) at 85 °C (Dardir et al 2014). The resultant curves at this temperature provided a proper understanding of the flow model of the IMME (O/W) emulsion mud at temperatures relevant to wellbore and varying shear rate (Jha et al 2016).…”

Drilling muds with less environmental impact are highly desired over conventional diesel-based mud systems, especially in light of the emerging strict environmental laws. In this article, a novel oil-in-water (O/W) emulsion drilling fluid formulated with a methyl ester extracted from Indian mango seed oil was evaluated. The effect of the weight percent of different constituents of the emulsion/suspension including the oil phase, bentonite, and polyanionic cellulose polymer on the rheology and the fluid loss was examined. The methyl ester oil phase/mud system displayed superior physical, chemical, rheological and filtration properties relative to the diesel and the mango seed oil. Eco-toxicity of the methyl ester and diesel (O/W) emulsion mud systems was assessed using the acute lethal concentration test. The Indian mango methyl ester (O/W) emulsion mud displayed much less impact on fish population. Flow characteristics collected from the flow model at 85 °C suggested excellent shear thinning behavior of the Indian mango methyl ester (IMME) (O/W) emulsion mud. Moreover, the IMME (O/W) emulsion displayed strong pseudoplastic behavior, an attractive feature in a drilling mud, with increasing clay content and polymer concentration. The methyl ester mud was thermally stable over a wide range of the constituent concentrations. Furthermore, a particle size analysis revealed that engineered drilling muds targeting suspension of particles with certain size range can be formulated by changing the volume fraction of the methyl ester in the mud system.

In deep wells and ultra-deep wells drilling beside the shores, the corrosion of drilling tools in oil fields is a common phenomenon. It is presumed that drilling corrosion loss of drill pipes scrap had accounts for a significant proportion of the entire cost of drilling. The most common way to control the corrosion in oil or gas wells is by chemically corrosion inhibition methods using inhibitors, which added to reduce the total drilling costs and enhance the drilling safety. In this research, we discussed the different effects of some new prepared cationic and non-ionic surfactants based on nitrogen and oxygen atoms as corrosion inhibitors additives for water-based drilling fluids. The corrosion rates were reported, the evaluation of water-based drilling fluids studied according to API specifications through the determination of rheological and filtration properties. The obtained results revealed that these prepared compounds regard as good corrosion inhibitors for the water-based mud.

“…Such products are oil-soluble, possess low hydrophile-lipophile balance (HLB) values (2-3 units) and, thus, are considered effective emulsifiers of water-inoil emulsions that are widely used, for example, in oil and gas production (Bondarenko et al, 2015;Fink, 2013;Ibragimov et al, 2017;Mardashov and Rogachev, 2014;Minaev et al, 2014;Rogachev et al, 2011). The main methods to prepare ethanolamides comprise aminolysis of FA esters, including triacylglycerols (TAG) and ethanolamines (Adewuyi, 2014;Adewuyi et al, 2012;De Almeida et al, 2013;Kumar et al, 2015Kumar et al, , 2016Wang et al, 2016), and direct FA amidation with ethanolamines (Boshui et al, 2013;Dardir et al, 2014;Lokhande et al, 2013;Mäki-Arvela et al, 2016;Yanovsky et al, 2013). Currently, the former method finds the greatest application due to the "soft" conditions of the aminolysis process, the simplicity of the hardware design, and the availability of raw materials.…”

The effects of the duration of direct amidation of fatty acids (FA) with diethanolamine on the composition of the products obtained, their surface‐active properties, and ability to stabilize water‐in‐oil emulsions are studied using the example of tall oil distillate. A certain range of synthesis time that corresponds to the maximum content of diethanolamides in the reaction products, and, as a consequence, the highest surface‐active and emulsifying properties of the products is shown to exist. An increase in the synthesis duration time leads to a deterioration of these properties due to accumulation of the products of secondary reactions. A new mechanism of the amidation process that includes secondary transformations of diethanolamine and its condensation products with FA into 1,4‐bis(2‐hydroxyethyl)piperazine derivatives is proposed. The structures of by‐products are confirmed using high‐performance liquid chromatography‐mass spectrometry (HPLC–MS), infrared (IR), and nuclear magnetic resonance (NMR) spectroscopy methods. It is concluded that the acid value of the product as well as the amount of water released during the synthesis cannot serve as a reliable criterion for completion of the process.
