An Integrated Approach to Design Completions for Horizontal Wells for Unconventional Reservoirs

Abstract

This paper presents a comprehensive and integrated workflow to design completions for a heavy oil recovery process that involves injection and production through the same well. Unlike in traditional completion design, the transient effects are particularly important to consider while analyzing the long-term performance for these types of completions to capture the effect of variations or uncertainties in reservoir and fluid flow characteristics over time. The proposed integrated workflow involves initial screening and selection of flow restricting completions that can meet the desired injection and production performance based on a detailed wellbore hydraulics modeling tool. A select few completions are then analyzed for longer term performance using a reservoir simulator that couples the flow restricting nature of completions with flow in the reservoir. The use of best-in-art wellbore hydraulics model and reservoir simulator in a staged process yields an effective way to assess and optimize the completion design for these wells in a reduced time span. The workflow disclosed here can be used to design effective completions for a broad class of cyclic liquid injection methods for heavy oil resources.

As drilling operation is progress, reservoir model is updated and coupled with simulation software to situate the good structure and provide a more realistic drilling (Chemali et al, 2014).…”
