A Petroleum Industry’s Asset

  • An ASSET is a useful or valuable thing, person, or quality
  • For an oil & gas company, an asset is an oil field or gas

field that is capable of making money

  • An asset has a life cycle, just as I do

̶ Beginning of life ̶ Youth ̶ Middle age ̶ Retirement

Geoscientists help management make good business decisions:

− Collect & analyze data − Develop an understanding of the subsurface − Determine the implications for oil/gas

Our Work in a Nutshell Much of our work is about making predictions:

− Which blocks hold the greatest HC potential? − Will I find an economic amount of oil at location X? − How much oil will I recover with 5 wells? − Can I increase production with 2 injector wells?

Some Key Questions

In the EXPLORATION phase

  • Which basins should we work?
  • Which blocks should we bid on?
  • Where should we drill on our blocks?
  • What might we find?

In the DEVELOPMENT phase

  • Should we develop this field?
  • Where are the sweet spots?
  • How can we get the most HCs out?
  • Will we make money?

In the PRODUCTION phase

  • What still remains?
  • How can we get maximum production?
  • How can we save money?
  • When should we walk away?

FWSchroeder

  • Which sediment layers have a lot of organic

matter – plant or animal remains?

  • Have these layers been “cooked” enough so we

have generated oil or gas molecules?

  • If they have, in which direction did the oil or gas

molecules move? Questions?

12

slide-13
SLIDE 13

FWSchroeder

  • Are there any porous layers – like a sponge – to

hold the HCs?

  • Do the porous layers have a geometry such that

they can “pool” enough oil and gas to form a field?

  • Is there a sealing rock layer to act as a “ceiling”

keeping the oil or gas trapped in the “pool?” Are There Any Traps?

Sandstones “bend” into a fault; oil is trapped in the highpoint of the “bend” A large salt body has “squeezed” up at this location and “dragged” sandstones with it; oil & gas are trapped against the salt body

  • Regional Geology

– Provides an understanding of which areas are productive, why they are productive, and where else we should look.

Geoscience in Petroleum Industry

  • Geology

– Analysis of cores, logs, analogues and databases to understand the geology where we operate.

  • Basin Modeling

– Quantitative integrated models

  • f the petroleum system.
  • Geophysics

– Provides an image of the subsurface and data useful for predicting rock type and the

  • ccurrence of petroleum.
  • Structural Geology

– Provides an understanding of the process of deformation of the subsurface due to external forces.

  • Stratigraphy

– Provides an understanding of processes creating sedimentary units.

  • Geochemistry

– Chemistry of petroleum and its sources to characterize the type, history and origin of petroleum.

  • Reservoir Characterization

– Describes the flow characteristics and attributes of subsurface reservoirs for enhanced exploitation.

OBJECTIVE: Walk through the exploration process to illustrate the exploration process starting prior to a lease sale, simulating a bidding round, maturing a prospect, and showing how a wildcat well would be presented to management.
