PROVOKING THOUHHTS
  • With the nuclear industry in crisis and oil prices on the rise, could the solution to our energy problems be in the ground at home? Daniel yergin on the promise of shale gas.
  • He ," states that the turmoil in the middle east is a "sea change" for the global oil market and that the U.S.A and emerging markets are most economically vulnerable to rising oil prices.

INTERNATIONAL SCENARIO

FOR UNCONVENTIONAL

RESERVOIR

india shale gas cbm projects
India Shale Gas & CBM Projects
  • Started work on CBM 1993
  • Group of experts was formulated to collect and analyze data.
  • 32 BLOCKS Have been given to different companies
  • Now India started Production from CBM
  • Next Few Years, Production will be 38 CM^3/day
  • ONGC had Recent Discovery of Shale Gas in West Bengal
indigenous oil gas reservoirs
Conventional Reservoirs

Sandstone and carbonate Reservoirs.

With good reservoir properties have good capability of storage and Productivity

Reasonable Efforts for Exploration

Explored area is about 275,000 Sq km

550,000 Sq km is unexplored

Current Production

Oil: 60000-66000 bbl

Gas: 4.15 BCF

Unconventional Reservoirs

Poor reservoir properties have capability of storage but poor Productivity

Tight Gas Reservoir

Shale Gas Reservoir

Coal Bed Methane

NOT DEVELOPED YET

Indigenous Oil & Gas Reservoirs
unconventional reservoir descriptions
Tight Gas Reservoir

Mostly Sandstone Reservoir

Good storage Capability but poor Producibility.

Distributed over Large Area of Pakistan

Advance Technology Need to Produce

Shale Gas reservoir

Exist in Shale

Source and Reservoir

Good storage Capability but poor Producibility

Distributed over Large Area of Pakistan

Advance Technology need to Produce

Unconventional Reservoir Descriptions
unconventional reservoirs
COAL BED METHAN (CBM)

Gas is generated during Coalification Process

Gas Adsorbed on the Coal

Very poor conductivity

Distributed over Sindh & Punjab Province

Word 10 % Coal Deposits are in Sindh

Total Deposits are 185 billion tone.

Not developed Yet

No Conclusive Work

Unconventional Reservoirs

    • Vastly Distributed- 100 -1200
  • Thalar Shale
    • Vastly Distributed – 45 – 184
  • Samber Shale
    • Vastly Distributed – 500- 600
  • Chichali Sahle

  • Vertical & Horizontal well
  • Multilateral Wells
  • Hydraulic Fracturing
  • Stimulation Techniques
exploration production companies
Exploration & Production Companies
  • Should Invest to Explore Tight and Shale gas
  • Exploration area for Tight and Shale Gas should be awarded to the companies
  • Price Incentives have been given
  • Freedom of Marketing of Gas to the Consumer
manufacturing power industries
Manufacturing & Power Industries
  • Should have direct access to Energy Producer
  • Should have option of buying gas from Producer & paying Tariff to the distribution company for using the network if required
  • Reference Price should be according to the concession area
  • Distribution Companies should effectively assist for supply of gas to Industries
  • Consortium of Industry units to share the cost of energy.
cost effective buisness model
Cost Effective Buisness Model
  • Exploration Companies- Consortium
    • Work Program for next 3-4 years
      • Drilling of Vertical, horizontal & Multilateral
      • Hydraulic Fracturing/Stimulation jobs
  • Service Providers-Consortium
    • Bring Relevant Technology
    • Efficient Execution of jobs
    • Cost effective Solution
  • Human Resource Development---Serious Consideration
continue
Continue----
  • Need consortium of industry units for sharing of their cost of energy
  • No Misuse of Freedom
  • No Monopolization of any company weather it is service or distribution companies.

summary
SUMMARY
  • Enough unconventional Reservoir exist

in the country

  • Unconventional Reservoirs are required to be evaluated by collection of more data by initiating Pilot Projects in Shale Gas as earliest as possible.
  • Exploration blocks may be awarded for unconventional reservoirs.
  • Economically, Projects in Shale & Tight Gas looks viable.

Continue----

  • Human Resource Development to cater the demand of oil companies operating in Pkistan
  • Introduction of consortium concept of E & P companies for the planning of their work
  • Consortium of Service companies for cost effective solution of development of these Reservoirs.
  • Integrated Approach of all the stack holder is required to develop these unconventional Reservoirs
