Optimizing Well Trajectory Using Sequential, Hybrid Sequential, and Fully Concurrent Method Utilizing Machine Learning: A Case Study of a Tight Limestone Reservoir

Abstract This paper describes the process and results of using machine learning to automatically determine the optimum well trajectories for a tight limestone reservoir. The study aimed to find the best trajectories to maximize gas production while following certain constraints related to safe drilling operations and surface limitations. These constraints included the available surface locations, …

Managing New Development Uncertainty with Scenarios and Multiscale Modelling: An Integrated Study of the Fogelberg Discovery

Recent hydrocarbon developments are generally characterised by high complexity and uncertainty with lower margins for error in an unpredictable financial market. This is further compounded by new oil and gas discoveries being typically smaller today, than in the past; highlighting the need for robust and fit-for-purpose reservoir models that accurately capture key uncertainties to inform …

New Approach for the Probabilistic Assessment of Organic Matter in the Source Rocks of the Bazhenov Formation for Estimation of Shale Hydrocarbons Resources

Abstract Maps of organic matter distributions are an essential part of the basin modeling process for evaluation of conventional and unconventional hydrocarbon resources. This approach has become widespread for both assessment of the initial oil and gas generation potential and final assessment of the resource base. An important step in this method is pyrolysis of …

Subsurface to Surface Network Modeling for CO2 Sequestration in a Deep Saline Aquifer

Integrating the subsurface model for CO2 sequestration with the surface facilities model is very important to ensure long term deliverability of CO2 to the subsurface formation. In this paper, A compositional dynamic reservoir model is fully implicitly integrated with wellbore and surface network model to evaluate CO2 sequestration in a deep saline aquifer, located offshore …
