“…The calcium chloride based HDBs are the best choice for such highpressure conditions, while sodium chloride-based HDBs are employed for less severe conditions and cost-effective operations. 149,150 The region-specific utilization of HDBs demonstrates their adaptability in addressing the demanding geological and operational issues encountered in different regions of the world. The selection of the HDBs is done on the basis of conditions encountered during the drilling operations to ensure safe and efficient commencement of the drilling and completion operation.…”

Fluids for drilling and completion operations are essential components in the oil and gas industry. With the advancement of drilling technology, effective drilling fluid for harsh drilling operations is still challenging to exploit hydrocarbons. One of the prominent developments in this area is the application of high-density brines. The high-density brines have shown the capacity to tackle complicated harsh geological conditions. This review paper gives a detailed review of the properties, formulation, application, and importance of high-density brines in drilling and completion processes. The factors affecting the salient features of high-density brines, such as chemical composition, temperature, pH, and pressure, are discussed. Furthermore, the paper investigates the application of high-density brines in the oil and gas industry as drilling fluids, where they play a crucial role in wellbore stability, formation fluid control, and cuttings transport. In addition, this review highlights emerging trends and research to improve the performance of high-density brines. Finally, the review discusses current challenges and outlook, environmental concerns, economic feasibility, and compatibility with wellbore materials. The current ample review serves as beneficial literature for research scientists, engineers, and industry experts looking for a massive knowledge of high-density brines and their diverse applications.

The use of gels in oil production processes has become a regular practice in oilfield operations and is constantly developing in all oil-producing countries of the world, as evidenced by the growth of publications and patent activity on this topic. Many oil production processes, such as hydraulic fracturing, conformance control, water, and gas shutoff, cannot be imagined without the use of gel technologies. Inorganic, organic, and hybrid gels are used, as well as foams, gel-forming, and gel-dispersed systems. The possibility of a broad control of structural and mechanical properties, thermal stability, and shear resistance by introducing microscale and nanoscale additives made hydrogels and hydrocarbon-based gels indispensable tools for oil engineers.

“…The main growth of the explored mineral resource base reserves is provided by such fields [14,15]. A wide range of research is focused on studying the oil's properties from such fields, as well as the conditions peculiarities of their development and prospecting [12,[16][17][18][19]. Many works show the accumulation of hydrocarbons in collector rocks, which are presumably the results of biodegradation.…”

Thermodynamic and Experimental Substantiation of the Possibility of Formation and Extraction of Organometallic Compounds as Indicators of Deep Naphthogenesis

In this article, typomorphic associations of microelements in carbonaceous caustobioliths and oils are defined as indicators of naphthogenesis based on the analytical survey of the literature and our own research. Various approaches to the studying of crude oil genesis from the position of abiotic and complex approaches (polygenesis) are considered. Such approaches are relevant to the prospect and development of offshore oil deposits, localized at ultra-deep levels. For deep deposits, the most prominent hypothesis of oil origin is the abiogenious theory. In the foundation of that approach lays the assumption that hydrocarbons are formed mainly due to reactions of the formed mantle gases and the host rock. Key factors for these reactions to proceed are specific conditions concerning temperature, pressure, and specific catalysts. The article presents the results of thermodynamic and quantum-chemical modeling of the possibility of the organic and organometallic compound formation using the software package HSC Chemistry 6.0. Pointed out the possibility of a low molecular weight hydrocarbon formation due to the contact of ascending flows of mantle gases with cooling natural barriers. The primary synthesis proceeds with the interaction of fluid forms of H2, CO2, and H2S. The estimation of the bonding energy depending on the structure of organometallic compounds was performed using the Avogadro software package. The program used the method of bond potential energy minimization to find the most stable structure of molecules. The metals nickel and vanadium, as the main companion metals of oil, are of the most interest from the position of analysis of their form of existence in the possible formation of hydrocarbons. Vanadium’s and nickel’s accumulation in asphaltene fractions of oils, probably, is caused by complex compounds of metalloporphyrin’s formation. In addition, the high sulfur content is probably associated with polymerization of organic molecules due to the formation of di-sulphide bonds. The method of cavitation extraction of organometallic compounds from oil and complex mineral–oil raw materials has been developed for experimental confirmation of microelements the extraction capability from oil raw materials.
