P3

Delivers selective production enhancement or injector well cleanup for significant flow improvement

P3 treatment reduces skin selectively by removing trapped debris that resists flow from existing perforation tunnels, producing immediate and often significant results. Applied in hundreds of environments globally, this solution has objectively demonstrated improved reservoir-to-wellbore communication with flow rate increases ranging from 20% to 400%.

The selective process enables increased potential production from production zones and leaves high skin at the perforations in zones producing unwanted water or gas.

• In geothermal wells, the treatment removes scale from slotted or predrilled liners.
• In injection wells, the treatment removes filtered solids that reduce injectivity; when these wells have screens, it cleans inside the screen.
• In openhole wells, the treatment clears out natural or induced open fractures or openhole perforations.
• In soft rock, the treatment cleans perforation tunnels to accept gravel.

Clears perforation tunnels using dynamic underbalance technique

P3 treatment employs a patented dynamic underbalance technique to break up and remove near-wellbore flow impairment damage (typically called skin) from existing perforating tunnels.

The treatment's system consists of an implosion chamber, which is positioned over the target interval. Once triggered, the resulting implosion strips material from flow bottlenecks, removing perforation damage or deposits on slotted liners and screens and obstructions in near-wellbore fractures.

The magnitude and duration of the implosion are modeled using the PURE Planner perforation job planning application; flow or injectivity improvements can also be predicted using SPAN Rock stressed-rock perforating analysis and measured objectively using production logs or by monitoring surface flow rates and pressures.
