MEETING
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 Pesticid 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.

Date & Time:
12:00 Noon, Friday, March 13, 2009 Location: North Dakota Heritage Center, Bismarck, ND
American
Association of Petroleum Geologists
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

2008 MEETING
NOON LUNCHEON Date & Time: 12:00 Noon, Tuesday, November 20, 2008 Location: North Dakota Heritage Center Project Room A Speaker: Bob Markhouse, ND Department of Health Topic: World Oil Update – Supply and Demand Part II Topics touched on will include: 1. Oil development impacts on local water infrastructure in the western part of North Dakota 2. Mexico – oil production and consumption update 3. Russian oil tax policy and impact on exports 4. Brazil – new oil find, Santos Basin (funding issues) 5. Canadian oil sands project delays 6. Coal to liquids potential? 7. Oil price roller coaster 8. IEA oil price prediction (new report issued this week) Robert made a presentation on world oil supply at the April, 2008 meeting. We thought that with the turbulence we have seen in oil and gasoline prices over the last few months, a brief update would be interesting. Robert’s interest in the world oil supply has become something more than a hobby with him, as indicated by his excellent April presentation. Don’t miss this one.

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.
