Survey and Reports

SANGEA 4.3 GHG Emissions Estimating System

SANGEA™ is an emissions estimation software tool for the oil and natural gas industry to quantify greenhouse gas (GHG) emissions and standardize emissions reporting. It is based on the 2009 API Compendium of Greenhouse Gas Emissions Methodologies for the Oil and Gas Industry and US EPA Mandatory Reporting Rule Subparts C, P, W and Y, including recent updates (RY2015) to US EPA MRR reporting requirements. The software also includes US EPA AP-42 emission factors for criteria pollutants.

For pricing and ordering information, please visit the API Webstore.

Quarterly Well Completion Report (QWCR)

The QWCR provides detailed information on reported drilling activity and estimates the total number of wells and footage drilled. The estimates of quarterly completions and footage are displayed by well type, well class, and quarter for the ten years prior. More detailed estimates of quarterly completions and footage are disaggregated by well type, depth interval, and quarter for the current year and two years prior. In addition, wells reported to API (not estimates) are listed on a state and regional level, disaggregated by well class, well type, and quarter, for the current year and two years prior.

Published in the first week following the end of the quarter.

For questions, please contact Harper Cohen at CohenH@api.org.

Joint Association Survey on Drilling Costs (JAS)

The JAS is an annual survey that contains the only long-term source of information of detailed U.S. drilling expenditures on wells, footage, and related expenditures in the United States. An Analysis & Trends section provides detailed information and graphs about offshore and onshore wells, shale wells, coalbed methane wells, and sidetrack wells. The data presented in the U.S. Summary Tables section are broken down by well type (oil wells, gas wells, and dry holes) and by depth interval. Additionally, the data in these tables are disaggregated by well class (exploratory wells and development wells) and offshore and onshore production.

Discontinued in 2025, latest report available is December 2024.
