Integration, An Opportunity for
Petrophysics to Generate Value
Richard Rosen (Richard L. Rosen Consulting)
Petrophysics, as Archie thought about it, is the science of
understanding the physical properties of rocks. As such, it
uniquely impacts the practices of all of the petroleum and
geoscience disciplines. Each disciplines’ work can be thought of
as a set of assumptions and facts about the response of rocks to
the various exploration and development efforts. Value is
therefore generated by the creation of knowledge and its
reduction in uncertainty. From a risk discount point of view,
reduction of risk generates cash.
Integration, in this process, requires petrophysics to
understand the nature of these assumptions and to divine methods
to turn these assumptions into facts. The priority of these
tasks depends solely upon how they influence actions among
management in regards to the “So What?” and “Now
What?” questions which drive the business. The quixotic
pursuit in these endeavors requires a paradigm shift from
technology is a cost to technology is an investment.
There is a profound difference between the two philosophies in
that costs are evil and must be destroyed and the
expectation of returns on an investment.

Pulsed Neutron Logging and Formation
Evaluation in Unconventional Reservoirs: Case Studies
Jorge Gonzales Iglesias (Schlumberger)
With the ever-increasing pressure to become more efficient in
the oil and gas industry, from spud to completion of a well,
acquiring measurements for describing reservoir properties in
unconventional reservoirs have become an anomaly. Geoscientist
teams are often left frustrated with limited data, such as
gamma-ray (GR) and even drilling events, to populate their
reservoir models.
From a formation evaluation (FE) stand point, the preferred
method to acquire reservoir measurements is in open-hole (OH)
conditions. This option is generally perceived as costly due
mainly to the rig time required for the logging job and to a
certain extent, the operational risks involved. It is then when
the alternative of cased-hole (CH) logging becomes attractive
since the previous factors are eliminated.
Cased-hole formation evaluation has been around since the
1950’s when GR and a neutron logs were used in conjunction to
attempt evaluation through casing. Resistivity logs through
casing were also emulated with the introduction of Sigma (S) and
Carbon/Oxygen (CO) measurements in 1960’s and 1970’s
respectively. The complexity of today’s reservoirs makes the use
of these measurements (GR, Neutron and S) still insufficient to
produce a reliable FE for unconventional reservoirs.
It was not until late 1970s, early 1980s that pulsed neutron
log tools (PNL) started to introduce spectroscopy information
that would allow to quantify the various minerals of the
formation for either OH or CH environments. Early tools provided
limited accuracy and precision as well as complex acquisition
programs with extremely low logging speeds and a large number of
logging passes that required intensive data manipulation and
processing. It is perhaps both; the time consumed for the
logging job and the time required to provide an interpretation
that have hindered the PNL cased-hole alternative from being a
more widely used option in FE by the industry to date.
Fortunately, technology has hugely evolved since early
introduction of PNL tools and today slim PNL tools offer the
possibility of acquiring such measurements mentioned earlier at
much more faster speeds. Remarkable improvements in accuracy and
precision as well as in computing software performances, allow a
log analyst to turn around reliable interpretations in time with
well schedules.
This paper summarizes the latest advancements of a slim PNL
tool that can acquire simultaneously, sigma, neutron and the
measurement of a new formation property known as the fast
neutron cross section (FNXS) along with spectroscopy data for
lithology information. The tool logged in this mode, combines
time- and energy-domain spectral in a single mode at speeds up
to 1000 feet per hour that makes a logging job much more
attractive and operationally appealing. A series of case studies
are shown to demonstrate the elevated specification of this new
technology with a variety of applications from unconventional
reservoirs to enhanced oil recovery.

Effective Core Description, Interpretation and Data Capture
Workflows in Mudrocks (or any rocks, really)
Katie Joe McDonough (KJM Consulting)
Goals and focus of core description and interpretation
efforts may vary, and ideally should be established at the
outset of any project. Despite relatively easy subsurface
correlations in many unconventional plays, the problem of
understanding vertical and lateral reservoir property
distribution persists. Carefully targeted, captured and
calibrated rock data can determine the correspondence between
depositional facies, stratigraphic stacking and reservoir
characteristics such as porosity, permeability and brittleness.
This information placed in stratigraphic context can then
facilitate lateral prediction of reservoir properties away from
the borehole (because… Walther’s Law!
"Vertical=Lateral.").
Any core description workflow must begin by establishing a
Level of Detail appropriate to achieve the objectives of the
project. These objectives should be client-customized,
goal-oriented and designed to answer specific questions
formulated at the outset. Ideally, detailed observation and
facies delineation is then constrained by this project design
and its implicit Level of Detail. Sedimentologic facies
characteristics are then defined conventionally according to
lithology, sedimentary structures, bedding types and fabric as
well as ichnofabrics and trace fossil information. Details
matter, but only if understood in context of the larger scale.
Keeping LOD context requires designing the workflow so that
larger scale ‘views’ are available and accessible during the
course of observation and data collection. Using best practices,
facies and sedimentologic data should be captured quantitatively
and digitally using tools available. This allows immediate
comparison and integration with wireline logs, petrophysics and
seismic data.
Following (and during) sedimentologic facies
characterization, ideal workflows incorporate facies trend
interpretation to delineate stratigraphic stacking. This
critical step allows up- and down-scaling to basin or reservoir
scale, and represents an often-overlooked
integration/interpretation step which greatly enhances utility
of rock data. Once stratigraphic stacking is delineated, the
hierarchical interpretation can be applied to understand
petrophysical crossplot relationships to depositional facies as
well as facies fabric relationships to mechanical stratigraphy.
This leads to improved understanding of the controls and
predictability of reservoir occurrence, distribution and
performance.
Examples of tailored description/interpretation workflows and
approaches applied to the following geologic intervals will be
discussed:
Data Capture: Sedimentologically-defined facies, cycles and
stratigraphy
- Cretaceous Niobrara
- Eocene-Oligocene Mudrock
- Cretaceous Marias River Shale
- Devonian Bakken Shale (Basin margin facies)

Assessing shales from well logs: a
calibrated workflow with examples from the Bakken
Sue Cluff and Stefani Brakenhoff (The Discovery Group)
The Discovery Group has developed a standard workflow used to
calculate total organic carbon (TOC), lithology, grain density,
TOC-corrected porosity and water saturation, that is useful in
most shale reservoirs. The model requires a standard
triple-combo log suite and shale-analyzed core data to calibrate
the model. This method has been successfully applied
to basins both domestically and internationally.
We will show how to develop shale models using a
deterministic work flow with an example from the Bakken shales
of North Dakota; beginning with data collection practices,
stepping through all of the processes needed for developing
shale-corrected models, and applying these models to a database
environment used to create valuable characterization maps and
statistics of the shales.

Extension of the Gameboard Approach for Facies-based
Petrophysical Model Development
Margaret Lessenger (Rimrock Petrophysics) and Samuel Fluckiger (SM Energy)
Petrophysicists develop petrophysical models using common
petrophysical software packages. These packages facilitate
development of models calibrated to specific zones defined
either by geological formation tops or depths within a well.
Well logs respond to the physical properties of the rocks near
the wellbore. These physical properties are grouped into
distinct rock and log facies. Commonly, multiple different
facies occur within defined zones, complicating zonal
petrophysical models. Because well logs respond to facies within
zones, facies-based petrophysical models are a significant
improvement from zonal petrophysical models.
In this paper we present a workflow for developing facies-based
petrophysical models for porosity and saturation. This workflow
is an extension of the “gameboard” approach (Krygowski and
Cluff, 2015). Using the gameboard approach a petrophysicist can
quickly try multiple scenarios to find the parameters that honor
all the data. We have built a gameboard in Spotfire (©TIBCO), a
data visualization and analytical software package. Using
visualization and analytical software we utilize categorical
data (e.g., log and core facies, drilling fluid type), and quick
data visualizations including map-based visualizations to
calibrate petrophysical models.
We applied this workflow to the Upper Cretaceous Wall Creek
member of the Frontier Formation in the Powder River Basin, USA.
Core, log, and seismic facies have been defined in these
reservoirs (Fluckiger, et al., 2015). Multiple log facies occur
within sequence-stratigraphic zones, and there are lateral
facies changes within zones. We demonstrate the workflow for
developing improved petrophysical model parameters that vary
with log facies within stratigraphic zones.

NMR Applications in Unconventional Reservoirs
Dick Merkel (Denver Petrophysics)
The NMR measurement relies on signal from hydrogen not
chemically tied to the rock matrix. That makes this measurement
similar but yet different that the neutron porosity log which
will, for instance, measure the chemically bound water
(hydrogen) in gypsum. Most unconventional reservoirs have much
lower hydrogen ion concentration in the fluid component (hence
lower signal) than is found in conventional reservoirs. As a
result, different acquisition, processing, and interpretation
techniques are required to be applied in unconventional
reservoirs.
This presentation examines the NMR log acquisition of T1 and
T2 data and their interpretation for gas, oil, and water
content. Major breakthroughs in NMR analysis is occurring in
core measurements where higher frequencies can be used to look
at shorter T1 and T2 times. This allows for the analysis and
delineation of kerogen, bitumen, fracture content, and
compressibility as a function of pore size. Examples show how
the high frequency core data can be used in combination with log
NMR data for reservoir interpretation.

Using Horizontal Borehole Image Logs and Geomechanics to Enhance the Design of Hydraulic Stimulations
Roger Reinmiller (Borehole Image Specialists)
This presentation is a case study illustrating the
integration of borehole image log and geomechanical data to
improve stimulation results. The case study involves a vertical
pilot well with a full suite of open hole logs and three
horizontal wellbores with borehole images. A geomechanical
analysis augmented by mineralogy determination was performed on
the pilot hole. The three horizontal image logs reveal
substantial variation in the distribution of natural and
drilling-induced fractures and faults along the laterals. The
presence or absence of drilling-induced transverse and
longitudinal fractures can be directly linked to the changes in
frac gradient and proppant placement during fracture treatments.
Applying the vertical well geomechanical study to the layers
penetrated by the laterals, the geometry of the
critically-stressed fractures and faults were determined for
each horizontal well. Variation in differential stress along
each lateral and changes in the geometry of critically-stressed
fractures and faults significantly alters the induced hydraulic
fracture response (complex vs. planar fractures) in these
stages, ultimately governing production response.
Fracture gradient data, as they relate to drilling-induced
and critically-stressed fractures, can determine the stage
spacing and perforation clusters that should be used to optimize
the fracture stage design, custom fitting the stimulation to
lateral changes in stress anisotropy.
From production histories, we show that stage-by-stage
modification of the pump-ins, accommodating image derived
information, improved frac efficiency and EUR, even in highly
fractured laterals.

Pore Scale Imaging of Unconventional Reservoirs in
Petrophysical Workflows
Terri Olson (Digital Rock Petrophysics)
Imaging technology has advanced in recent years to enable
investigation of pore systems in very fine-grained reservoirs. A
review of state-of-the-art techniques will include methods
focused on nanometer- and micron-scale observations plus
integration across scales. Pore type, pore size, pore
connectivity, wettability, mineralogy and fabric are among the
aspects that are best addressed with such techniques in
microporous reservoirs. Questions that these methods address
will be discussed, along with their relevance to petrophysical
interpretation and their place in formation evaluation
workflows. Case studies will be shown to illustrate application
of pore-scale imaging to assessing tight sandstone and “shale”
plays.
Applications to tight sandstone in the Green River Formation
in the Uinta Basin in Utah include imaging wettability with
FESEM and associating altered wettability with specific mineral
phases; and detecting formation damage mechanisms in SEM images
taken before and after exposure to completion fluids. Shale
examples of workflows include combining MicroCT images, mineral
maps, FESEM images, and FIBSEM image data to yield both insight
and quantitative results.
Issues with image data, potential pitfalls in interpretation,
and new frontiers for core analysis based on imaging techniques
will also be covered.

The Role of Rock Properties in
Unconventional Resource Plays
Mike Mullen (Stimulation Petrophysics Consulting)
A key component of completing unconventional reservoirs is
the fracture stimulation treatment. So how does one determine
the optimal treatment volumes, stage spacing and entry points?
It could be a matter of trial and error. This is typically the
method used by a lot of operators. It is also an expensive
learning tool requiring a number of field trials. Another option
would be to use modern day frac modeling simulation programs to
run numerous “what if” scenarios to determine the ideal stage
spacing, entry points, fluid and proppant volumes as part of an
engineered completion program. The heart of these frac modeling
programs is a robust rock property model, pore pressure,
temperature and overburden gradient. The primary mechanical rock
property inputs are Poisson’s Ratio and Young’s Modulus.
Typically mechanical rock properties are determined by
running modern day Dipole Sonic logs. In Unconventional plays,
sonic logs are not always available in the pilot well and rarely
run in the lateral wellbore. In these cases, rock properties can
be estimated using neural networks or deterministic models. To
advance the state of completions from “poke and hope” completion
optimization scheme to a more engineered completion, rock
properties evaluation need to be estimated in vertical and
horizontal wells for input to fracture stimulation design and
modeling programs. So routinely calculating mechanical rock
properties need to be included as part of the unconventional
resources workflow toolkit.
