Conformance Improvement

Operators may encounter a variety of conformance problems, but their biggest challenge is correctly identifying the offending problem and then selecting, designing and executing the appropriate conformance-improvement technology. Whether water-shutoff or sweep-improvement technologies are required, TIORCO designs and executes treatments that are reservoir, well and problem specific.

Gel Technology

TIORCO's gel is made up of a polymer and a crosslinker. The polymer and crosslinker are added at the surface, and then injected down into the formation. The reaction rate is sufficiently delayed to allow placement some distance from the wellbore.

APPLICATION

Gel can be injected into production or injection wells to solve the following problems:

  • Producing Wells: Bottom water coning, early water breakthrough, fracturing out of zone, conduit from injector to producer, natural fractures connected to bottom water drive Bottom water coning, early water breakthrough, fracturing out of zone, conduit from injector to producer, natural fractures connected to bottom water drive
  • Injection Wells: Conduit from injector to producer, injection out of zone, thief intervals of natural fractures or high permeability streaks. Conduit from injector to producer, injection out of zone, thief intervals of natural fractures or high permeability streaks.

ADVANTAGES

    • Robust, versatile gel chemistry that does not require exact chemical concentrations
    • Can be designed for use in almost any type of mix water
    • 80% success at reducing water production at least 60% without reducing oil
    • May not require zone isolation in fractured reservoirs
    • Can place large volumes to block water flow paths further out from the wellbore than other methods, which reduces new flow paths bypassing the gel
    • Temperature threshold up to 2100F
    • Payout is often within 6 to 9 months, based on incremental oil production alone

    CRITICAL DESIGN FACTORS

      • Producers with surface fluid levels are excellent candidates
      • Perfs must be clean so the gellant can be readily injected
      • Minimum efficient injection rate and maximum injection pressure constrain treatment volumes
      • Should be able to place at least 1,000 BBLS of gel without reaching pressure limit
