Location: Lower-Level X-Room, North Dakota Geological Survey, 1016 E. Calgary Ave., Bismarck ND 58503, Bismarck, ND Speaker: Stephan H. Nordeng Ph. D, North Dakota Geological Survey Steve is a subsurface geologist with the North Dakota Geological Survey. He received his B.S. and M.S. degrees in geology from Michigan Technological University and a Ph. D. in geology from Michigan State University. During the last four years Steve has been investigating the geologic factors associated with the current production from Bakken Formation with an eye on applying the lessons learned from the Bakken to other formations in the Williston Basin. Topic: Geological Modeling using Petra- focus on the Tyler Formation The Tyler Formation is an organic-rich, regionally extensive unit that is similar in some respects to the Bakken Formation. However, the Tyler is found some 2,000 feet above the Bakken so that questions exist as to whether or not the Tyler has been subjected to high enough temperatures to generate oil. Evidence that suggests that the Tyler is capable of generating oil is provided by a small dataset consisting of recently obtained Rock Eval data coupled with a simple basin model.

NOON LUNCHEON Date &Time: Noon, Tuesday, April 19, 2011 Location: Lower-Level X-Room, North Dakota Geological Survey, 1016 E. Calgary Ave., Bismarck ND 58503, Bismarck, ND Speaker: Timothy Nesheim, Subsurface Geologist, North Dakota Geological Survey Topic: 3D Models of the Williston Basin Abstract: Recently the North Dakota Geological Survey developed a three dimensional model of the Williston Basin in northwestern North Dakota, a model that extends from the surface to depths of over 15,000 feet. This model consists of multiple three dimensional geologic units that were generated within the computer program Petra (surface style: minimum curvature) using a geophysical log top database compiled from over 8,000 oil and gas wells. Modeled units include: the Spearfish, Tyler, Mission Canyon (Madison), Bakken-Three Forks, Prairie, and Red River formations, the Dakota Group, Pierre Fm.-Colorado Group, and the Precambrian basement. Many of the significant Williston Basin structures can be easily seen with surprising detail within this three dimensional model. For example, several well defined ridges can be traced along the crest of the Nesson anticline, especially within the Mission Canyon Formation. In the Dakota Group, both the concentric rim and the central peak of the Red Wing Creek Impact structure appear very pronounced. Even smaller, more subtle features such as the Newporte Impact structure and the Little Knife anticline can also be observed. Over 900 horizontal wells were also plotted within this model in order to show the recent development within the Bakken-Three Forks system.

After graduating from Iowa, he took a temporary research position at Washington State University’s geochemical clean lab. He is currently a subsurface geologist with the North Dakota Geological Survey where he has spent most of his time examining the Tyler Formation’s resource potential and building a three dimensional model of North Dakota’s subsurface.

Association of Petroleum Geologists
Distinguished Lecturer Series From outcrop analogue to flow simulation: Understanding the impact of geological heterogeneity on hydrocarbon production. Abstract Hydrocarbon reservoirs are geologically heterogeneous over a wide range of lengthscales. This heterogeneity is a key control on fluid flow during hydrocarbon production, because geological (sedimentary, structural and diagenetic) processes dictate the spatial distribution of petrophysical properties such as porosity, permeability, relative permeability and capillary pressure. These properties control the flow of oil, water and gas. Consequently, to understand, model and predict fluid flow, it is essential to understand and model geological heterogeneity. This is challenging for two reasons. The first is that geological heterogeneity is complex, ranging from the scale of individual pores (c. microns in length) to the scale of the entire reservoir (c. kilometres). The second is that subsurface data is limited. Well data has high spatial resolution but is sparsely distributed; seismic data is extensive but has low spatial resolution. Poor understanding of geological heterogeneity leads to increased uncertainty in predictions of hydrocarbon recovery, and increases the risk associated with hydrocarbon extraction. Recognizing that a reservoir model cannot represent explicitly every type and scale of heterogeneity raises a number of persistent questions. What are the key types and scales of heterogeneity that models should capture? Are these key heterogeneities the same for all reservoir and hydrocarbon types, and all recovery processes? What is the minimum level of model resolution/complexity required to make recovery predictions that are ‘good enough’? How should models best capture these key heterogeneities? To answer these questions requires the development of models based on rich datasets which capture heterogeneity at a high level of detail. Such models can be constructed using analogue outcrops. This presentation describes ongoing research to develop and apply outcrop analogue models, emphasizing the use of novel surface-based modelling techniques in conjunction with adaptive gridding/meshing for flow simulation, and the insight gained into the impact of geologic heterogeneity on flow. The approach is illustrated using examples of shallow-marine sandstone reservoir analogues from three contrasting depositional environments across a hierarchy of lengthscales. The environments represented by the analogues comprise (1) a single, wave-dominated shoreface-shelf parasequence, (2) two stacked, fluvial-dominated deltaic parasequence sets and (3) multiple stacked, tide-dominated channel belts and tidal heteroliths. The datasets were obtained from well-exposed outcrops in Utah, USA, the Western Desert, Egypt and the Isle of Wight, UK; they describe reservoir architecture in generic analogues for many shallow-marine reservoirs. The model results demonstrate that subtle aspects of reservoir architecture, which are typically neglected in subsurface models, can have a significant impact on flow and hydrocarbon recovery. Conversely, features which are routinely included because they are easy to model may be unimportant to flow. New reservoir modelling methods are required to capture subtle, yet important, geological heterogeneities. The methods developed here to handle outcrop datasets are equally applicable to subsurface reservoirs. They rely less on grid- or pixel-based methods, and integrate better with a new generation of reservoir simulators. Biography

Distinguished Lecturer Series Granite to Grass Roots: Understanding the Geological History of Unconventional Resource Basins from Bottom to Top Abstract The competition for unconventional resources in North America has resulted, in some cases, to acquisition of acreage prior to thorough understanding of subsurface technical risks or identification of fairway boundaries and sweet spots. Indeed, the term “resource play” implies to some that subsurface risks are either minimized or irreducible. As well, the term “unconventional gas” connotes that little is to be gained from application of conventional principles of basin evolution and petroleum generation, migration, and entrapment. Under these circumstances, the value of regional geologic understanding of an entire basin prior to acreage capture can be overlooked and the focus turned to completions technology and post-well analysis. This lecture will discuss the importance of understanding a basin from basement to surface – granite to grass roots – in the search for unconventional fairways. The lecture will include a holistic integration of data and interpretations from basin modeling, petroleum migration modeling, gas isotope data, pressure history, seismic, and reservoir quality. Linkages will be made from microscopic scale observations to tectonic-scale processes. Examples will be given from various North American basins that illustrate how mega-scale features such as basement architecture and Precambrian rift history have a first order and transcendent effect on the evolution and occurrence of unconventional resource fairways, including a strong influence on petroleum generation and entrapment as well as changes in reservoir rock during post-orogenic uplift.

NOON LUNCHEON Date & Time: 12:00 Noon, Tuesday, April 21, 2009 Location: North Dakota Heritage Center, Project Room A Speaker: Skip Vechia, North Dakota Water Science Center, US Geological Survey Topic: Trends in Pesticide Concentrations in Corn Belt Rivers Trends
in the concentrations of commonly occurring pesticides were evaluated
for major rivers of the Corn Belt, an agricultural region that accounts
for a major proportion of pesticide use in the U.S. Trends were
evaluated for 31 sites in the Ohio, Great Lakes, Upper Mississippi, and
Missouri River Basins using a parametric regression model designed for
analyzing seasonal variability and trends in pesticide concentrations
(SEAWAVE-Q). The SEAWAVE-Q model accounts for the effect of changing
flow conditions in order to separate changes caused by hydrologic
conditions from changes caused by other factors, such as pesticide use.
Most of the pesticides assessed were dominated by varying degrees and
significance of concentration downtrends during the analysis period
(1996–2006), except for atrazine, acetochlor, and prometon, which were
relatively stable, and simazine, which was dominated by concentration
uptrends. Overall, trends in pesticide concentrations were consistent
with trends in agricultural use. Taken together, results indicate that
(1) use was the most important factor governing trends in water
concentrations of the pesticides evaluated, (2) use and concentration
trends were usually consistent in direction and magnitude, and (3)
sorting out the causes of the relatively few disagreements between use
and concentration trends will require reliable basin-scale information
on pesticide use and agricultural management practices.

Distinguished Lecturer Series New Petroleum Reservoir Modeling Techniques Improve Field Management and Optimize Recovery Abstract Because of the extremely high cost of developing a subsurface reservoir, commonly a billion dollars or more, it is critical to understand the volumes of hydrocarbon that are present within the reservoir and the amount that can be recovered. Each well is expensive, so we must make the most of the information collected from each well to constrain the uncertainty surrounding the architecture of the reservoir, its extent, and its internal heterogeneities, as well as the impact on recoverability. We approach this by constructing a geocellular model of the hydrocarbon accumulation that incorporates a reasonable range of possible reservoir characteristics, and then simulate the flow of fluids - hydrocarbons and water - throughout the life of the field. The results from any reservoir simulation are strongly dependent on the accuracy of the underlying geologic models. Until recently, it has not always been possible to build geocellular models that accurately portray the subsurface geology. Over the past several years, Chevron has developed a new geologically-based modeling workflow, which combines Multiple Point Statistics (MPS) and Facies Distribution Modeling (FDM) to generate a 3D geologically-robust geocellular reservoir model. MPS is an innovative depositional facies modeling technique, developed by Chevron in collaboration with Stanford University, which incorporates 3D geological concepts in training images that more accurately integrate geological information into reservoir models. Training images allow MPS to retain complex spatial relationships among multiple facies and to model non-linear shapes such as sinuous channels or irregular bar forms that conventional variogram-based modeling techniques typically fail to reproduce. In addition, because MPS is pixelbased, not object-based, MPS models can be constrained by very large numbers of wells. FDM is a novel technique that is used to generate a facies probability cube to better constrain the facies spatial distribution in geostatistical models. The MPS/FDM workflow above is preferred to variogram-based and object-based techniques to model important Chevron assets in both shallow-water and deepwater clastic reservoirs, and more recently, in carbonate reservoirs. Additionally, this workflow has been used in synthetic studies to explore the potential impact of architectural and textural parameters on flow behavior. Using experimental design methods, it is possible to determine the relative impact on production of a variety of field parameters. With this information, one can focus on better understanding the key subsurface parameters and gather new data to reduce their uncertainty. This work flow enables field management by lowering risk and optimizing production. Funded by the AAPG Foundation FEBRUARY 2009

Hydraulic Fracturing—Measurement,
Characterization, and Analysis
August 11, 2008,
8:30 am – 4 pm
Minot State
University, Student Union Conference Center
Minot, North Dakota
Fee: $195, Instructor: Jennifer Miskimins, Colorado School of Mines, Golden, CO This one-day workshop is intended to demonstrate recent advances in hydraulic fracturing techniques and how they can be used to characterize the producing reservoir. The basics of hydraulic fracturing are discussed and lead into the complexities associated with treatment design and analysis. Special issues such as non-Darcy flow, G-function analysis, and “mapping” techniques are covered. Case studies demonstrating analysis and various fracturing practices (such as “slickwater” fracs) are presented.
