10
The Mantra for choice of Specialty Chemicals
Use Inflow Performance Relationships (IPR) with
respect to introduced Technology/ Specialty
chemicals to determine the Applied Technology/
Specialty Chemicals ability to raise the
Productivity Index(PI).
11
Example 1 Inflow Performance Relationships (IPR)

Type of Drilling Fluid Systems Cost Rs (Lacs) Likely Productivity Barrels/day
1. Conventional lt10 100 (Base case)
2. Polymer 10-25 110-130
3. Non-Damaging 25-50 130-150

WELL COST
  • EARLIER CHEMICAL COST
  • FOR DRILLING WELL 3-4
  • PRESENT CHEMICAL COST
  • FOR DRILLING WELL 10-11
  • FUTURE CHEMICAL COST
  • FOR DRILLING WELL 20-25

33
  • TWO ASPECTS TO INCREASED COST
  • DEVELOPMENT COST OF SPECIALITY CHEMICALS ITSELF
  • END RESULT PERFORMANCE - USING SPECIALITY
    CHEMICAL
  • GIVEN THE ISSUE, I SHALL PUT IN -----
  • At the end Market forces will decide which
  • Specialized Chemical/Services will be
    adoptive
  • in the prevailing Scenario

34
  • A Specialty Chemical which is not
  • economically applicable today can be a
  • front runner and also be acceptable
    tomorrow
