MULTILATERAL COMPLETION TECHNOLOGY

One well.
More reservoir.

Connect multiple reservoir targets through one well. Build the junction around the access, isolation and completion your application needs.

01 / RESERVOIR

Increase exposure.

Reach additional targets and connect undeveloped intervals through lateral wellbores.

02 / INFRASTRUCTURE

Share the well.

Use a common main bore and upper completion for multiple reservoir branches.

03 / OPERATIONS

Plan the access.

Select a junction and re-entry strategy for completion, production and future intervention.

THE TECHNOLOGY FAMILY

Choose the junction.
Design the access.

TAML levels describe multilateral junction construction. Select a level to explore the architecture and the decisions it supports.

SUPPORTED LATERAL JUNCTION

TAML 3

A cased main bore with a lateral liner mechanically connected at the junction. The completion design establishes the required access to the well branches.

Multilateral well construction overview showing branches with TAML levels 1 to 5

The TAML level describes the junction; selective access and pressure isolation depend on the selected system and well design.

SPECIALIZED DOWNHOLE HARDWARE

Whipstocks, Anchor Packers & Circulating Subs

Build the hardware scope around the operator’s well geometry and required completion outcome. Discuss production and open-hole whipstocks, retrievable whipstocks, anchor packers, standalone orienting subs and circulating subs, together with window mills, follow mills, dress mills and retrieval hooks.

Application engineering defines casing and liner interfaces, tool dimensions, connection requirements, material selection, pressure and temperature envelopes, and the manufacturing, inspection and acceptance requirements for the proposed assembly. Final specifications and qualification evidence are agreed for the selected configuration.

MECHANICAL ACCESS · VIDEO

POV — On-demand mechanical access

Surface equipment demonstration of the TAML 3 mechanical access arrangement. Illustrative footage; intervention compatibility and downhole performance require project-specific verification.

TAML-3 LITE + TEMPORARY ISOLATION

Two packages.
One completion workflow.

Construct the lateral while preserving the original bore. Then use temporary isolation to support the transition from stimulation to production equipment.

PACKAGE 01

Multilateral construction

01

Set & mill

Run the anchor-packer, whipstock and milling assembly together. Isolate the original bore and create the casing window.

02

Complete the lateral

Drill and install the lateral completion selected for reservoir and operating conditions.

03

Reconnect the main bore

Dissolve the specified temporary closures through acid treatment and restore the original flow path.

PACKAGE 02

Temporary wellbore isolation

04

Pump down & land

After the final fracturing stage, pump the dissolvable plug to its landing profile below the liner hanger.

05

Change the upper completion

Verify isolation, release the stinger and recover the treatment string. Install the required production equipment.

06

Dissolve & reconnect

Select the material for the well conditions and isolation period. Reconnect the isolated interval as the plug dissolves.

APPLICATION ENGINEERING

The right system
starts with the well.

Define the casing and liner geometry, junction location, reservoir objectives and operating envelope. Match the equipment to the required stimulation programme and future access.

  • New-well or sidetrack configuration
  • Junction support and pressure requirements
  • Completion, stimulation and sand-control interfaces
  • Re-entry, isolation and intervention strategy
