Each month the U.S. Energy Information Administration (EIA) produces its Drilling Productivity Report (DPR), our favorite monthly report. The DPR estimates how much oil and natural gas each of the country’s seven largest shale plays produced in the previous (current) month, and how much each will produce in the coming (next) month. The February DPR showed, for the first time, combined natgas production from all shale plays would decrease beginning in March (see EIA: Shale NatGas Production Declines First Time in 39 Months). The EIA tweaks their numbers up and down each month. They badly underestimated how much of a gas production drop all shale plays would experience in March, including the Marcellus/Utica.
