These articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

  • GRAVITATIONAL-SORPTION METHOD FOR EXTRACTION OF VANADIUM-CONTAINING OIL FROM RESERVOIRS WITH THE USE OF REDOX POLYMERS   Order a copy of this article
    by Bulbul Nuranbayeva 
    Abstract: The article considers the possibility of extraction of residual oil reserves, based on the use of previously drilled wells and creation of conditions for drainage of formation fluid into production wells due to gravity forces and sorption processes of vanadium interaction in oil with injected redox polymers. The article makes a significant contribution to world science when studying the processes of extracting residual oil reserves from reservoirs and metals from liquid media, including oil. As a result of the analysis of the proposed method of extraction, the authors for the first time prove that the technology under consideration allows increasing the oil recovery factor and expand the scope of redox polymers when extracting oil from seams and associated metals. The proposed redox polymers have improved physico-chemical, oxidation-reduction and sorption-kinetic prop-erties. Their application will allow solving the actual problem of import substitution of expensive foreign products for oil production. This makes it possible to implement integrated development of such oil fields as Buzachi and others with the extraction of associated metals and to improve the quality of oil and oil products.

  • Selection of friction reducer for slickwater fracturing to achieve both fracking robustness and production maximization   Order a copy of this article
    by J. Jim Wu 
    Abstract: Fracking robustness and production maximization are the ultimate pursuits of slickwater fracturing. The former requires an all-weather applicability of slickwater, whereas the latter dictates the fluid to be non-damaging to reservoir formation. Since friction reducer (FR) is the mere indispensable component of slickwater, the requirements for fluid essentially translate to that for this FR. In this report, attempt is made to describe experimentally and comparatively the outcomes of FR screening based upon current industrial practices, which are often contradictory in nature, followed by the authors opinions and recommendations. Two commercially available FRs, with distinctive properties, were chosen for demonstration. Regarding fracking robustness, the assessments include a series of compatibility and friction flow loop examinations. The aspects of production maximization are elucidated through core flood regained perm, proppants pack elution and filtration through porous media experiments. A simplified FR selection guide is proposed with its validity corroborated by field results.
    Keywords: slickwater; hydraulic fracturing; friction reducer; fracking robustness; production maximization; brine tolerance; formation damage.

  • A technique to fight against formation damage via turbulence control for saltwater disposal   Order a copy of this article
    by J. Jim Wu, Wendy Jiang, Rixing Zhang, Nellie Chu 
    Abstract: Due to environmental concerns, operators are often required to dispose their produced saltwater into disposal i.e. SWD wells. The key challenge is that the saltwater contains varieties of damaging species with compositions varying batch-wise. In addition, the compelled turbulence during pumping worsens the situation further. As the results of constant formation damage and lack of turbulence-taming measure, SWD wells frequently experience rapid pressure escalation during operation, which is a major hurdle holding back this industry. In this report, we walk through the identification of key issues facing SWD, followed by the proposal of a prospective solution. The solution consists of primarily a real-time well stimulation via turbulence control with a non-damaging friction reducer that works essentially in all common oilfield brines. The qualification and screening of this friction reducer, as a technique to fight against formation damage via turbulence control, is described, followed by the corroboration with field results.
    Keywords: saltwater disposal; friction reducer; well stimulation; turbulence control; formation damage mitigation; SWD pressure taming.
