Horizontal & Multilateral Well Completions
This course covers the completion of horizontal and multilateral wells. Participants study horizontal well inflow and flow behaviour, open hole and cased hole options, zonal isolation, inflow control, TAML junction levels and construction, re-entry and intervention access, and the operational practice of running and cementing long laterals.
Description
Horizontal wells expose far more reservoir than vertical wells, and multilaterals extend that reach further by branching from a single wellbore. The productivity gain is real, but so are the difficulties: long laterals do not produce evenly, zonal isolation is harder to achieve, cementing and running equipment in a long horizontal section is demanding, and every junction in a multilateral is a potential source of integrity and access problems.
This course covers the completion of both. It starts with horizontal well inflow performance, friction in the lateral and heel-to-toe effects, then covers completion options from barefoot and slotted liner to cemented and perforated, with zonal isolation using swell and mechanical packers. It covers inflow control briefly and in context, then moves to multilateral wells: the TAML junction classification, junction construction and integrity, re-entry access, and the planning of drilling and completion sequence. The course closes with running and cementing practice in long laterals and with intervention and surveillance in these wells.
A horizontal well is not a vertical well turned sideways. Inflow is distributed along a long section, friction in the lateral means drawdown varies from heel to toe, gravity segregates phases along the wellbore, and liquid accumulates in low spots of an undulating lateral. These effects influence completion design, artificial lift and the interpretation of everything measured in the well.
Zonal isolation is the second challenge. Cementing a long lateral well enough to isolate zones is difficult, and uncemented completions rely on swell or mechanical packers to divide the annulus. Without isolation, annular flow lets fluid move along the well outside the completion, which defeats inflow control and makes zonal shut-off impossible.
Multilaterals add the junction. TAML levels describe increasing degrees of mechanical support and hydraulic isolation at the junction, from an open hole split to a fully pressure-isolated cased junction. Higher levels cost more and take longer, but a junction that collapses or cannot be re-entered turns a multilateral into a single well with an expensive history. The design question is what level of junction the reservoir and the intervention plan actually require.
By the end of this training, participants will be able to:
- Explain horizontal well inflow performance and the effect of lateral friction and heel-to-toe drawdown.
- Assess phase segregation, liquid accumulation and flow behaviour in long laterals.
- Compare barefoot, slotted liner, expandable, and cemented and perforated completion options.
- Design zonal isolation using swell packers, mechanical packers and cementing.
- Apply inflow control in horizontal completions where flow distribution requires it.
- Describe the TAML junction classification and select a junction level.
- Plan multilateral drilling and completion sequence and junction construction.
- Plan re-entry and intervention access in horizontal and multilateral wells.
- Specify running, cementing and clean-up practice for long laterals.
- Plan surveillance and production logging in horizontal wells.
The course is instructor-led. Horizontal well flow behaviour is developed from first principles and applied to completion choices, with worked examples for inflow and friction effects. Multilateral junction levels, construction and re-entry are taught through drawings, procedures and field cases, including junction failures. Participants are encouraged to bring their own well designs and problems for discussion.
Organisations sending participants to this training will:
- Get horizontal completions that produce evenly along the lateral.
- Achieve reliable zonal isolation in long horizontal wells.
- Select multilateral junction levels suited to the reservoir and intervention plan.
- Reduce operational problems when running and cementing long laterals.
- Preserve intervention and re-entry access over well life.
Participants will:
- Understand how flow behaves in long horizontal wellbores.
- Be able to select and design horizontal completion options.
- Understand zonal isolation methods and their limits.
- Understand multilateral junction levels and construction.
- Be able to plan intervention and surveillance in horizontal wells.
