Failure of a Multilateral Well
Application ID: 666
Multilateral wells—those with multiple legs that branch off from a single well—can produce oil efficiently because the legs can tap multiple productive zones and navigate around impermeable ones. Unfortunately, drilling engineers must often mechanically stabilize multilateral wells with a liner or casing, which can cost millions of dollars. Leaving the wellbore uncased reduces construction costs, but it runs a relatively high risk of catastrophic failure both during installation and after pumping begins.
The poroelastic simulations estimate 3D compaction related to pumping by taking subsurface fluid flow with Darcy’s law and coupling it to structural displacements with a stress-strain analysis. This model focuses on elastic displacements brought on by changing fluid pressures when pumping begins.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- either the 多孔質媒体流れモジュール, 構造力学モジュール, or 地下水流モジュール and
- either the バッテリデザインモジュール, CFDモジュール, 化学反応工学モジュール, 腐食解析モジュール, 電気化学モジュール, 電気めっきモジュール, 燃料電池&電解槽モジュール, マイクロフルイディクスモジュール, 多孔質媒体流れモジュール, or 地下水流モジュール
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the 製品仕様一覧 and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
