Impact/Purpose:

This is an abstract for a presentation at the Natural GasSTAR Annual Implementation Workshop on November 16-18, 2015 in Pittsburgh, PA. The subject is methane emissions fro abandoned wells. This is a report on interim progress on a effort we have with ERG. OAP is involved in the project and will review slides.

Description:

Reconciliation of large-scale top-down methane measurements and bottom-up inventories requires complete accounting of source types. Methane emissions from abandoned oil and gas wells is an area of uncertainty. This presentation reviews progress to characterize the potential inventory impacts of abandoned wells for the U.S. . Available methane emission rate data for abandoned wells is reviewed and some of the ongoing research to better characterize emissions is discussed. Efforts to compile a database of well drilling activities since the 1870’s for each state and each state’s establishment of well plugging standards for abandoned wells is described. Progress towards an estimate of national methane emissions from abandoned wells and major sources of uncertainty are presented. These emissions are put in to context by comparing to other sources of methane emissions from oil and gas production activities.
