  Sargent Sand
Sand Mining operation in Ludington
  Speaker: Al Henning

Time: 7:00 pm, March 16th

Place:  Community Church

The Sargent family of Bay City acquired a major portion of the Ludington Dunes around 1920.  Mining of surface sands under the auspices of the Sargent Sand Company has therefore also been part of this resource development.  Since the large-scale deployment of hydraulic fracturing methods in the US oil and gas industry (beginning around 2005), Sargent’s historically low-scale operations have been transformed dramatically in size and scope, with a coincident transformation in their consequences.  Al will discuss what he has learned about
1. the process of hydraulic fracturing, in the US in general, and locally in particular;
2. the use of sand as a ‘proppant’ (to prop open the cracks, or fractures, in that process);
3. the present and future sources of proppants;
4. the economics of surface sand mining; the status of law in the State of Michigan relative to surface sand mining;
5. the reduction to practice of those laws by state regulators; and
6. where Sargent Sand Company, and its neighbors, fit within the local, state, and national landscapes.


He will finish the talk with a discussion of what the future holds for the dunes contiguous to the Ludington State Park.


Al Henning was born in Chicago in 1955, and was raised in the suburbs northwest of the city. He received his bachelor’s and master’s degrees in physics, in 1977 and 1979 respectively, from Dartmouth College.  Following employment with Intel in Santa Clara, CA from 1979 to 1982, he returned to graduate school at Stanford, and received his Ph.D. in electrical engineering in 1987.


His career has spanned large companies (Intel), academe (as a professor of engineering at Dartmouth), and small start-up companies in the area of micro-fabricated integrated circuits, micro-scale flow control systems for industrial and home refrigeration applications, and biosensors for personal and clinical healthcare.
