Abstract Reservoir engineers tend to define a simulation model as “complex” when they have several of the following characteristics: This paper is going to discuss the implementation steps and procedures utilized to history matching one of Abu Dhabi’s complex onshore reservoirs model. This reservoir has high levels of unknown parameters with uncertainty. Our key objective …

Abstract Due to strong non-linearities in the diffusivity equation, numerically-assisted rate-transient analysis (RTA) techniques have been suggested for analysis of multi-phase production data from multi-fractured horizontal wells (MFHWs). However, these methods are based on some limiting assumptions that cannot be generalized for three-phase flow or when relative permeability is unknown. In this study, a new …

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 …
