IS SEGREGATION-INDUCED GRAIN BOUNDARY EMBRITTLEMENT
A POLYMORPHOUS MELTING PROCESS?Nghi Q. Lam
Argonne National Laboratory
Argonne, IL 60439 A number of important contributions to our understanding of solid-state amorphization and segregation-induced grain boundary embrittlement have been made
in recent years. The two processes have traditionally been regarded as completely different phenomena belonging to different branches of materials science. However, recent systematic studies on Ni-S alloys have revealed striking similarities in the kinetics of S-implantation-induced amorphization and S-induced grain boundary embrittlement. In this presentation, we examine the underlying thermodynamics and show that both phenomena can be regarded as a polymorphous melting process. Disorder-induced melting of grain boundaries gives rise to low fracture resistance due to the ability of a crack to propagate readily through amorphous material.All first year MASC students are required to attend.

Graduate Seminar
"Polymers for Bionanotechnology."Dr. Karen Christman
Postdoctoral Scholar
University of California at Los AngelesAbstract
Over the past few decades, techniques to produce submicron and
nanoscale features on surfaces have emerged. While such advances
were initially applied to the electronics field, the fusion of biology and
nanotechnology has begun to provide useful tools for biosensors,
biomaterials, and tissue engineering applications. The ability to
spatially orient and anchor proteins in particular affords many
opportunities for biotechnology and medicine. Site-specifically
immobilizing proteins, forming protein assemblies, and fabricating threedimensional
biological nanostructures using various polymers and
lithography techniques will be discussed.Monday, November 27, 2006

De-Watering of Hunton Reservoir – What Makes It Work

Distinguished LectureDe-Watering of Hunton Reservoir – What Makes It Work?Dr. Mohan Kelkar
Department of Petroleum Engineering
The University of TulsaAbstract
Hunton Reservoir in Oklahoma represents one of the largest discoveries in Oklahoma in
recent history. Since 1995, several fields in Hunton Reservoir have been exploited by
various operators. The principle behind this exploitation remains the same. The wells
produce large quantities of water, and along with it, significant quantities of gas, and
sometimes, oil. Examination of various fields producing from Hunton reservoir indicates
that the economic success from these fields is not uniform. Some fields produce
significant quantities of oil, whereas, some fields only produce gas. In some fields,
horizontal wells work the best, whereas, in some other fields, vertical wells do a good job.
The water production from the fields ranges from as low as few hundred barrels per day
to several thousands of barrels per day.
In this presentation, we present the results from various fields to indicate the
parameters needed in Hunton field to make it economically successful. We restrict our
evaluation to parameters which can be easily measured or are readily available. These
include log data (gamma ray, resistivity, neutron and density), initial potential data,
production data (oil, gas, and water – if available) and well configuration (vertical or
horizontal). By comparing the recovery of oil and gas to various reservoir parameters,
we develop methodology for predicting the future success of the field. For example, a
clear relationship exists between porosity of the rock and initial hydrocarbon saturation.
Higher the oil saturation, better is the recovery factor. Initial potential is critical in
determining the possible recovery. Horizontal wells cost 1.5 to 2 times more than
vertical wells, but may not provide the additional recovery to justify the costs.
Similar formations exist in other parts of the U.S. If we want to extend the
success of some of the fields to other areas, we need clear guidelines in terms what is
needed to exploit those fields. This presentation provides some of those guidelines based
on the examination of the currently producing fields.Thursday, November 30, 2006
