Abstract Operators in the unconventional arena are endeavoring to improve project economics by optimizing well count per section, landings, spacing, and completions given the conditions of commodity price, geology, and fluid characteristics. In multi-bench developments, pressure variation and phase segregation are two of the contributors affecting well performance. This paper presents multiple observations (development cases) …

Abstract The main drainage strategy in Brage-Statfjord reservoir is pressure support by water injection to produce light oil. Continuous water injection is effective in maintaining the reservoir pressure and improving the volumetric sweep efficiency. However, waterflooding can leave behind large volumes of un-swept oil, mainly in the roof/attic of the reservoir. This attic oil can …

Abstract: Reliable reservoir simulation is essential for effective reservoir management in the petroleum industry, as it enables engineers to make well-informed decisions on production strategies and resource allocation. However, accurately calibrating reservoir models to match observed field data remains a significant challenge. This difficulty primarily arises from the inherent uncertainties in key parameters such as …

Abstract In this work method to improve the efficiency of the development of shallow deposits of extra-heavy oil using cyclic team stimulation (CSS) technology together with injection of catalyst for in-situ upgrading and solvent was proposed. Oil-soluble catalyst has been developed. Efficiency of catalyst was proved in laboratory. Volume and conditions of catalyst and solvent …
