How to use Michigan Natural Gas Production Reports

The Michigan Public Service Commission (MPSC) receives monthly production volumes from operators and transmitters of natural gas produced from Michigan's natural gas wells.  The MPSC has jurisdiction over the production from gas wells only. The Department of Environmental Quality's Oil, Gas, and Minerals Division has jurisdiction over the production from oil wells, although the casinghead gas production from oil fields is reported to the MPSC.  The reports provided on the MPSC website are part of an ongoing project to provide the public with access to MPSC production data by production type. 


Production Types

Antrim Gas produced from the Antrim shale formation. The Antrim formation is a shallow gas producing reservoir which is productive across the northern part of the lower peninsula of Michigan. Some Antrim projects produce gas with CO2 levels as high as 30%.
Casinghead Gas produced from oil wells.
Dry Gas Gas produced primarily from the Niagaran reef formation. Production occurs over two trends of reefs in the lower peninsula of Michigan. The trends are commonly referred to as the Northern Trend and the Southern Trend.
PdC Gas produced from the Prairie du Chien (PdC) sandstone formation. The PdC is the deepest gas producing formation in Michigan and is productive over the central portion of the lower peninsula of Michigan.

Antrim Production

In the past, Antrim monthly production volumes reported to the MPSC have been either produced gas or sales gas. Produced gas volumes include carbon dioxide gas. Currently, some Antrim projects produce gas with as much as 30% carbon dioxide. Sales gas volumes do not include the carbon dioxide gas. MPSC staff have been working with producers to standardize Antrim gas production reporting so that all producers report sales gas volumes. Prior to June 1998, about one-half of the Antrim production reporters were reporting produced gas volumes with the other half reporting sales volumes. Since June 1998, the producers that were previously reporting produced gas volumes have switched to reporting a sales gas volume. Specifically, the MPSC is requiring a "delivered volume," which is the volume of the gas at the delivery point where the gas leaves Michigan Consolidated Gas Company's (or a Michigan Consolidated Gas Company affiliate) pipeline system. All producers are required to report delivered volumes.

Antrim production data is posted to the MPSC website on a monthly based in four report types (monthly summary, monthly detail, year-to-date summary, and year-to-date detail), each in PDF format. Antrim production is also available in Comma Separated Value (CSV) format. Annual production summary and detail reports for production from 1991 through current are also available on the MPSC website in the Michigan Natural GAs Production Reports Archive.  Additional data and reports may be available.  Please contact the MPSC Gas Operations staff for other report types or data inquiries.

Casinghead Gas Production

Prior to January 1999, Casinghead gas (produced from oil wells) monthly production volumes were reported to the MPSC as sales gas volumes or more accurately classified as final allocated volumes if transported on any MichCon pipeline. Effective January 1999, the production volumes are sales volumes or more accurately called delivered volumes. The difference between final allocated volumes and delivered volumes is the BTU adjustment (liquids) and fuel. The production volumes will appear higher prior to January 1999 for high BTU gas, (for example: PdC and Niagaran gas may have a lot of hydrocarbons in it and thus a high BTU measurement ), since the final allocated volumes took into account these BTUs. However, if the sales contract delivery point is still at the wellhead, then the delivered volume will be the final allocated volume since the title is transferred there.

Casinghead gas production data updates are posted to the MPSC website in Comma Separated Value (CSV) format. Additional data and reports may be available.  Please contact the MPSC Gas Operations staff for other report types or data inquiries.

Dry Gas Production

Prior to January 1999, Dry Gas (non-Antrim and non-PdC) monthly production volumes were reported to the MPSC as sales gas volumes or more accurately classified as final allocated volumes if transported on any MichCon pipeline. Effective January 1999, the production volumes are sales volumes or more accurately called delivered volumes. The difference between final allocated volumes and delivered volumes is the BTU adjustment (liquids) and fuel. The production volumes will appear higher prior to January 1999 for high BTU gas, (for example: PdC and Niagaran gas may have a lot of hydrocarbons in it and thus a high BTU measurement), since the final allocated volumes took into account these BTUs. However, if the sales contract delivery point is still at the wellhead, then the delivered volume will be the final allocated volume since the title is transferred there..

PdC Production

Production from the Prairie du Chien (PdC) formation is reported as monthly sales volumes for condensate and dry gas. Prior to June 1998, a condensate to dry gas (barrels to Mcf) conversion was determined by the operators and a condensed gas equivalent volume was provided. (For proration purposes however, the MPSC only regulates the dry gas production.) Beginning in June 1998, when the new joint MPSC/DEQ production reporting form EQQ-7101 came into use, the conversion was not required and so the condensed gas equivalent volume is no longer provided.

Dry gas production data updates are posted to the MPSC website in Comma Separated Value (CSV) format. Additional data and reports may be available. Please contact the MPSC Gas Operations staff for other report types or data inquires.

Homeowners often make risky assumptions about whether or not they should get their utility lines marked, but every digging job requires a call - even small projects like planting trees and shrubs. The depth of utility lines varies and there may be multiple utility lines in a common area. Digging without calling can disrupt service to an entire neighborhood, harm you and those around you and potentially result in fines and repair costs. Calling 811 before every digging job gets your underground utility lines marked for free and helps prevent undesired consequences.
