Multilaterals

Reduce total well construction costs and improve reservoir access.
Increasing reserves while minimizing investment is the focus for multilateral technology, which lets you confidently reenter existing wells. You can drill an additional lateral to increase reservoir exposure or branch more than one lateral to increase reservoir exposure and target complex reservoirs.
RapidConnect

Stable access for the life of the well.
RapidExclude

Reduce trips into the hole

RapidConnect multilateral completion system providing selective drainhole access and connectivity. Get superior junction stability and strength, improved drainage and excellent mechanical integrity with built-in lateral access. Use a simple, low-risk system with running procedures that minimize trips into the hole.

Minimize costs

RapidConnect components can be installed with the RapidAccess multilateral completion system index casing coupling (ICC) or with packer-based systems. With ICC and RapidConnect, you have a planning option for future laterals. At minimal cost, the ICC can be installed in advance for a permanent depth and orientation reference with full casing integrity until the window is milled.

Benefits

  • Reduce trips into the hole
  • Ensure stable access for the well's life
  • Get long-term stability in fragile shales, depleted reservoirs and mobile salts


The Schlumberger RapidExclude
junction is a high-strength junction for multilateral completions
RapidTieBack Quad System

Improve reservoir drainage

RapidExclude multilateral junction for solids exclusion is safe, reliable and extremely robust for full-size drilling diameters. The template and connector, effectively, are a single sand barrier with the continuous, locking rail engagement.

If individual reservoir compartment reserves are uneconomical, the RapidExclude junction using two laterals may penetrate more of the pay zone. A new plan developing a multilateral well producing from two or more compartments may be successful.

Identify risk

With risk assessment to identify the best location, RapidExclude can be used for

  • new or reentry wells
  • infill well drilling in mature assets
  • wells with different pressure regimes requiring inflow control.

Benefits

  • Improve reservoir drainage

RapidTieBack Quad System
Reliable multilateral access for maximum reservoir exposure.

Reliable multilateral access for maximum reservoir exposure

RapidTieBack nonmilling multilateral drilling and completion system lets you place closely spaced multiple junctions in the zone of interest and commingle production. Used primarily in heavy oil applications; also in many other oil and gas reservoirs.

This is an economical and reliable approach to using multilaterals for the optimization of heavy-oil reservoirs.

Increase flexibility

The premilled window and mechanically installed tieback require no steel milling, reducing the risk of equipment damage from milling debris. The multiple lateral branches can be selectively accessed.

The big bore lets you use openhole or liners in the lateral branches. The large-diameter liner sleeve allows you to pass completion tools, such as an electrical submersible pump (ESP), through the junction.



Multilateral Reentry System

Discovery MLT Multilateral Reentry System

Controlled, selective entry on coiled tubing for multilateral wells

Discovery MLT multilateral reentry system is cost-effective and operationally simple for maximizing performance of multilateral wells. The system sends a pressure signal to the surface confirming you've accessed the correct lateral.

Adjusting the suborientation, or bend, from surface and the real-time feedback to surface of window identification save a substantial amount of time. This significantly increases the chance of successful reentry on the first attempt. Only one run to the bottom of the lateral is required for confirmation.

Discovery MLT software

Using Discovery MLT software, you can display several essential parameters, such as the tool orientation relative to the lateral window. The application also monitors previous indexes and guides you through indexing cycles for accurate, real-time information downhole.

After the window is profiled, the software memorizes the window orientation and monitors the BHA orientation, facilitating the location of other windows.

You can determine job feasibility with our CoilCADE CT design and evaluation software and monitor and record real-time data with CoilCAT acquisition software.


RapidX

The RapidX multilateral system provides a simplistic approach to a TAML Level 5 multilateral solution

The RapidX is a ultra high strength junction that provides a full size-drilling diameter, through 9-5/8" casing with large size completion and intervention diameter that meets and exceeds the specifications required for TAML Level 5. The junction design is an evolution of the field proven RapidConnect and RapidExclude systems, to provide sand exclusion and hydraulic isolation at the junction without the need to manipulate a cumbersome completion into the lateral.

Improve reservoir drainage

The RapidX assures access for the life of the well and improved reservoir drainage. With a systematic quantitative risk assessment to identify the best location, the RapidX junction can be used for new or reentry wells, wells with different pressure regimes requiring inflow control or infill wells in mature assets. RapidX provides stability with a lateral exit in unstable shale, cap rock, and sand control at the junction with an exit in the reservoir. The RapidX multilateral system provides a simplistic approach to a TAML Level 5 multilateral solution.

Features

  • Internal and external hydraulic tight junction with 2500 psi rating
  • TAML level 5 junction without the need to deploy cumbersome completion in upper lateral
  • Ability to Cement, Gravel Pack, Run Expandable and Premium Screens in upper lateral
  • Simple proven system
  • Flexible Junction placement
  • Continuous locking rail
  • Available in 9-5/8" main bore x 7" lateral
  • Large diameter completion
  • Rigless, Slick Line or Coil Tubing selective reentry
  • Able to integrate Flow Control Valves and/or Pressure Gauges
  • No casing orientation required
  • Fully retrievable
  • For new and reentry wells
