Overview

• The increasing diversity and prosperity of
  petrophysical data presents options concerning
  how to utilize numerical data and qualitative
  data in a qualitative petrophysical workflow. The
  choice about which information to use, where and
  is typically a subjective procedure left to the
  specialist. He/she seldom discusses options with
  different areas and frequently remains unaware of
  chances. This practice of that information to
  use, where and how must be further analyzed and
  formalised with tips as to the reason why
  information is or isn't helpful. This thinking
  doesn't yet appear to have evolved in businesses
  but is the essential first step to strong
  integration. Much helpful information is
  dismissed by petrophysicists. We have to remain
  forever vigilant regarding the significance and
  potential purpose of new information items in our
  present workflows. Workflows has to evolve with
  new information, that can be our job, to use
  everything at our disposal at the most effective
  method. Most recognized workflows today require a
  Whole re-think to accomodate and harness all of
  the information available for that Area,
  Reservoir Sort and Reservoir Rock Sort (RRT)

Believe Data Hierarchy

• The foundation for how to position, characterise
  and completely exploit new info is the aim of
  Data Hierarchy.
• A Passive"Replies with" or a Lively"Calibrate
  to"? What exactly does the seasoned and capable
  petrophysicist intuitively use as standards for
  reservoir Info Hierarchy, which is standing data
  because of its usefulness? This petrophysicist
  indicates Directness, Accuracy and Spatial
  Definition would be the origin standards we
  intuitively search for. How can we browse through
  competing data collections and methods? Analyse
  That!
• Can we actually need FFV to get Permeability?
  This can be valuable during logging operations
  since it avoids the necessity to log the a lot
  more debatable FFV having an NMR instrument --
  such as FFV cannot readily be acquired in
  gasoline zones and logging can be slowed
  dramatically into a costly crawl at the belief
  the complete T2 spectrum has to be logged to
  attain useful NMR outcomes. Not so. It's
  generally 100 water, quickly polarizes and is
  quickly counted in ancient T2 time. Whilst
  service businesses might be conscious of how this
  may be attained it generally isn't in their
  interests to progress this kind of approach.
  Service companies job would be to conduct logs
  and make information to not evaluate your own
  reservoir. Really, many molds can be correctly
  assessed for permeability without so much as
  obtaining NMR data, place your"Interested
  Petrophysicist" to work on this one.

Why Log Free Fluid Volume? Think Data Hierarchy

• "It ought to be said that although
  over-determined, error-minimization
  (probabilistic) log investigations seem
  attractive they need to demonstrate the
  discontinuous core information has actually been
  properly extrapolated beyond center, instead of
  simply matched over center. Should they don't
  display mechanism(s) where the cored replies are
  secured to the log analysis version applied
  beyond center they've failed to exploit the more
  expensive and more precise core information, and
  revert to'log investigation' -- beating the
  petrophysical aim of coring. The rigid expansion
  of core information into uncored intervals is
  more challenging to show with probabilistic
  petrophysics compared to deterministic
  petrophysics, and is a main reason simple
  deterministic processes persist in the face of
  that which may seem as superior log analysis
  methods. Again, it's the intention of the writer
  that xx Field petrophysics is heart established,
  not log "

Elan, Multimin, Mineral Solver. Probabilistic or
Deterministic Petrophysics?

• "The curious petrophysicist might want to
  consider that using a multi-well, multiple linear
  regression of the very same curves (portmlr)
  provided a much better match to center but a
  weaker overall porosity. This is the reason the
  fixed stage zero porosity is missing in the MLR
  procedure and the climbing of pordn2sc
  (density-neutron shale fixed porosity) is
  pressured to some non-feasible worth (0.374),
  since heart porosity is of restricted selection.
  We all know the pordn2sc variable should be
  1.00! It's worth noting that the deterministic
  fixed point procedure (Juhasz 1988, Deakin 2002)
  overcomes the common limited assortment of core
  information by giving a zero porosity information
  stage, and is why the frequently disregarded core
  grain density ought to be incorporated into the
  log evaluation. Additionally, the'curious
  petrophysicist' might want to inquire him/herself
  the way an Elan/Multimin strategy incorporates
  this hard info "
