Abstract A compositional dynamic simulation model is fully implicitly integrated with a gas injection surface network model, to study the effects of CO2 injection into a depleted gas field. Multiple prediction scenarios are evaluated, under uncertainty, to reduce risk and improve decision making. We propose a workflow, composed of a geological sensitivity clustering step followed …

Abstract At present, the geological model of the Groningen gas field is one of the largest high-quality open data sets in the oil and gas industry. The purpose of this study is to demonstrate the possibilities of improving the Groningen model, as well as to illustrate some open questions regarding the application of geostatistics in …

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) …
