SealIT Solutions · Stavanger An introduction
Single-trip water shut-off

Arrest production decline.

A highly efficient, single-trip water shut-off system, deployed on e-line — engineered for the brownfield, hard-to-reach and challenging wells where conventional WSO solutions fall short.

i. Cost effective Lower cost vs. conventional WSO.
ii. Versatile Any inclination, broad ID range.
iii. Low risk Single trip, real-time feedback.
iv. Huge upside Restored output from mature assets.

01 — Applications

Where SealIT delivers value.

Engineered for the wells where conventional water shut-off solutions fall short — from declining brownfields to demanding downhole environments.

Brownfield & hard-to-reach wells

Maximise production from mature assets.

Reach the wells where every additional barrel matters most — without the cost or risk profile of conventional water shut-off.

  • Brownfield assets with declining production
  • Hard-to-reach wells where intervention is costly
  • Horizontal wellbores with open-hole gravel packs
  • Severe ID restrictions above the producing zone

Challenging well environments

Reliable shut-off where others can't reach.

A purpose-built system for the toughest downhole conditions — designed to perform when conventional technologies fail.

  • Engineered for demanding downhole conditions
  • Reliable, long-lasting water shut-off
  • Works where conventional technologies cannot deploy
  • Cost-effective alternative to traditional WSO
02 — Operating sequence

One run on e-line.
Four precise steps.

Deploy, set, inject, retrieve — with real-time feedback throughout the resin plug installation.

Place the resin

Two-component resin metered, mixed and placed with real-time feedback.

iv.   Release & POOH
Release from plug

Confirm & recover

Tool releases from the cured plug and is recovered to surface.

03 — Tool & specifications

Compact electronics.
Independent control downhole.

A single-trip system with onboard pumps, dual-component reservoirs, a static mixer and inflatable packers — designed for independent, real-time control of the resin and hardener mix.
