Time and Location:
Registration will begin at 7:30 AM, the program runs from 8 AM - 12 PM. The course will be held at University of Connecticut, Storrs, CT, Beach Hall - room 233 (updated 10-11-17). Further directions and parking information will be sent to registrants.
Laptop Required:
A windows laptop with Microsoft Excel (tm) installed is required for this course. Following registration, you will be provided to links to download other analysis software to be used in the course.
Course Objectives:
The objective of this course is to introduce attendees to the Dissolved Oxygen Alteration Method (DOAM) for characterizing wellbore flow in bedrock wells. The DOAM entails increasing the dissolved oxygen content of a well through bubbler aeration, then profiling periodically to identify changes in dissolved oxygen associated with flow conditions. The DOAM can be used to identify transmissive fractures and vertical flow direction under ambient and pumping conditions, and provide a cost-effective means of interpreting sampling results in consideration of three-dimensional factors that influence flow.
This course will begin with a review of the risks associated with two-dimensional site characterization, and the limitations of traditional techniques for wellbore flow characterization. The attendees will then be introduced to the DOAM as developed by Chlebica and Robbins (2013) as a cost-effective and logistically simple alternative for delineating wellbore flow in bedrock wells under ambient and pumping conditions.
The outdoor field demonstration will include aeration and monitoring of dissolved oxygen in a 300-ft bedrock well under pumping conditions. Attendees will record and analyze data while profiling. Following field testing, the instructors and attendees will reconvene in the classroom to discuss the results of the field test and answer any questions.
