• Alternative Desalination Processes

9. What we do?
• Media Filtration
• Clarification
• Dissolved air Filtration
• Oil Water Separation
• Reverse Osmosis
• Nano Filtration Membrane

10. -Type of Water -
• Produced Water Analysis/Treatment/
Dispose Off-
• Effluent water- of Production & Process
Plants-
• Underground Water & Resources for the CSR.
• Camp Portable Water Treatment.
• Camp Sewage Treatment.

11. PRODUCED WATER.
• Changing Characteristics of PW, relates with
the geochemistry of formations.
• Disposable Options must be capable of
handling the changing characteristics.
• Priority Relay on Oil Content &
Environmental Friendly Disposal/Usage.

12. First-R
- Reduce Produced Water
• Drilling Cultural of the Company.
• Consideration of PW- in Drilling Plan Stage.
• Remedial Plan- if Water Cone Created.
• Mechanical Blocking Devices.
• Water Shut Off Chemicals.
• Down Hole Water Separation.
• Down the Ground Water Separation.

13. Second-R,
-Reuse Produced Water
• Storage for Reuse after Treatment, as if
according per NEQS & IEQS.
• Underground Injection/Utilization.
• Agricultural.
• Industrial.
• Domestic.
• Drilling.

14. Third-R
-Recycle of Produced Water
• -Livestock Watering.
• -Irrigation.
• - Stream Flow Augmentation.
• - Rangeland Restoration.
• - Domestic.

15. First-E –Efficiency of the
Techniques/Technologies.
• Evolutions of Techniques:
• The Plea at this point is not to rush in to the Produced Water
Management or disposal; but to identify the most suitable techniques
that, the community of E &P may find helpful in selecting a total system
concept to meet the needs of, in a given situations & a particular regions
.Reliability:
• It is important the operators to consider recovery of oil
waste stream as well as PW .
• It is equally necessary to insist upon proven reliable
techniques for produced water disposal because produce
water generation is directly proportional with the E & P
activities.

16. First-E,
-Efficiency- Techniques/Technologies
• The Total amount of produced water for disposal
is not material amount estimated so, it could be a
exact conversions and substitutions.
• It must be emphasized that there is not a single
best method for making this produced water
environmental friendly.
• The pattern will vary locally with the availability
of resources i.e. resources & techniques, with in
priority of the Company & Country.

17. Second –E,
-Environmental Acceptability.
• Produced water disposal alternatives, must
consider the implicit & explicit environmental
impacts, their implementation and those
found inadequate should not be applied.
• Concern for the environment must be viewed
in large context of National & International
NEQS & IESQ Standard.

18. Third- E,
- Economic Viability & Flexibility.
• The best solution or management of produced water will be
the one with the lowest net cost. If the proposed disposal
will meet the other criteria. More complex techniques would
be more expensive, difficult to adopts because of unstable
economy of Asia and especially South Asia.
• However, the better the techniques, the higher the price &
the better the quality.
• Systems should be designed as front – end system that; can
be supplemented by new technology for down and up
stream MPW, when such additional equipments become
available and reliable.

19. Constrains-
• Lack of Awareness from individuals to
institutions & decision levels.
• Economy constrains- variations country to
country.
• Regulatory & Implementations-Country to
Country.
• Priorities within the Government & Regulatory
bodies, & E & P Companies.
• Top Management Understanding with in the
three,- government, regulatory bodies &
Executioners.

20. RECOMMENDATIONS
• The 3R’s -must be look after at the local, regional &
National level i.e. Companies & Countries.
• It is necessary to choose a combination of solutions for
Management of Produced Water, most suitable,
considering the 3 E’s for that particular situations i.e. again
relate National & International, E & P Companies, -at
Countries & Continents levels.
• Technologies related Companies & Management of
Produced Water, must look the subject of today, i.e. the
scarcity of Water in Global Scenarios & MPW.
• Oil & Gas Waste Management should develop &
implement as a course subject in curriculum of education
levels in the Developing Countries.

21. “TOGETHER WE SHALL MAKE THE
DIFFERENCE”
