Reservoir Aspects of Horizontal and Multilateral Wells

Drilling and Completions Management and Information Reservoir Descriptions and Dynamics


This course includes discussion on the practical issues and reservoir parameters of horizontal well projects. The topics include formation damage, drainage areas, well spacing, well reserves, and rate calculations using steady-state and pseudo steady-state methods. The course includes several field case histories and performance analysis of horizontal wells.

Topics Include:

  • Drilling methods and costs
  • Well spacing and drainage areas
  • Recovery factors and steady-state solutions
  • Case histories: coning applications
  • Fractured horizontal wells
  • Forecasting production

Course Length

1 Day

Why Attend?

While horizontal wells are riskier and more expensive than conventional wells, the production gains may be worth it. This course teaches you when the technology justifies the risk.

Who Should Attend

This course is for reservoir, production, drilling, and completion engineers, managers, and other personnel who are interested in learning about selecting reservoirs for horizontal wells and understanding production performance of horizontal wells.

Special Requirements

Bring a calculator to class.
