Oil and Gas: Interior Could Do More to Account for and Manage Natural Gas Emissions
GAO-16-607: Published: Jul 7, 2016. Publicly Released: Jul 21, 2016.
The Department of the Interior's (Interior) guidance to oil and gas operators on its reporting requirements has limitations that may hinder the extent to which it can account for natural gas emissions on onshore federal lands (leases). Interior is required to ensure that oil and gas operations are conducted in a manner that minimizes waste. As part of its oversight activities, Interior requires op...
Maritime Transportation: Implications of Using U.S. Liquefied-Natural-Gas Carriers for Exports
GAO-16-104: Published: Dec 3, 2015. Publicly Released: Dec 3, 2015.
According to Department of Energy (DOE) and industry expectations, in the next few years the United States is expected to change from a net importer of natural gas to a net exporter, with those exports destined for different regions of the world, especially Asia. Five large-scale U.S. liquefaction facilitiesâ€”necessary for conversion of natural gas to liquefied natural gas (LNG) (see fig. below)â...
Pipeline Safety: Department of Transportation Needs to Complete Regulatory, Data, and Guidance Efforts
GAO-15-843T: Published: Sep 29, 2015. Publicly Released: Sep 29, 2015.
The Department of Transportation's (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) has begun but not completed efforts to improve pipeline safety in response to GAO's prior recommendations:Gathering pipelines : In 2012, GAO found that while gathering pipelines that are not regulated by PHMSA were generally considered to present less safety risk than other pipelines, PHMSA did...
Technology Assessment: Water in the Energy Sector: Reducing Freshwater Use in Hydraulic Fracturing and Thermoelectric Power Plant Cooling
GAO-15-545: Published: Aug 7, 2015. Publicly Released: Sep 8, 2015.
Waterless and water-efficient fracturing technologies such as gas-based fracturing or foams have been used to reduce the use of freshwater in hydraulic fracturing operations, although the main benefit is enhanced hydrocarbon recovery. The geologic formation characteristics of shale plays largely determine their use. According to experts GAO consulted, hydraulic fracturing operators are managing th...
Capitol Power Plant: Architect of the Capitol Should Update Its Long-term Energy Plan before Committing to Major Energy Projects
GAO-15-436: Published: Sep 3, 2015. Publicly Released: Sep 3, 2015.
The Architect of the Capitol (AOC) implemented many measures since 2008 to manage the energy-related costs of the Capitol Complex (the complex) and has opportunities to further manage these costs. AOC updated some of the Capitol Power Plant's (CPP's) production and distribution systems to reduce energy use and increase efficiency. AOC also implemented measures to reduce energy consumption in the c...
Electricity: Generation Mix Has Shifted, and Growth in Consumption Has Slowed, Affecting System Operations and Prices
GAO-15-524: Published: May 29, 2015. Publicly Released: Jun 29, 2015.
The mix of energy sources for electricity generation has changed, and the growth in electricity consumption has slowed. As shown in the figure below, from 2001 through 2013, natural gas, wind, and solar became larger portions of the nation's electricity generation, and the share of coal has declined. These changes have varied by region. For example, the majority of wind and solar electricity gener...
Oil and Gas Resources: Interior's Production Verification Efforts and Royalty Data Have Improved, but Further Actions Needed
GAO-15-39: Published: Apr 7, 2015. Publicly Released: May 6, 2015.
The Department of the Interior has made considerable progress in improving both the verification of oil and gas produced from federal leases and the reasonableness and completeness of royalty data. Since fiscal year 2009, Interior has implemented 28 of 36 GAO recommendations made in these areas; however, key challenges remain, including the following:Interior has not updated its regulations for on...
Oil and Gas Transportation: Department of Transportation Is Taking Actions to Address Rail Safety, but Additional Actions Are Needed to Improve Pipeline Safety
GAO-14-667: Published: Aug 21, 2014. Publicly Released: Sep 22, 2014.
Increased oil and gas production presents challenges for transportation infrastructure because some of this increase is in areas with limited transportation linkages. For example, insufficient pipeline capacity to transport crude oil has resulted in the increased use of rail, truck, and barge to move oil to refineries, according to government and industry studies and publications GAO reviewed. The...
Climate Change: Energy Infrastructure Risks and Adaptation Efforts
GAO-14-74: Published: Jan 31, 2014. Publicly Released: Mar 4, 2014.
According to assessments by the National Research Council (NRC) and the U.S. Global Change Research Program (USGCRP), U.S. energy infrastructure is increasingly vulnerable to a range of climate change impacts--particularly infrastructure in areas prone to severe weather and water shortages. Climate changes are projected to affect infrastructure throughout all major stages of the energy supply chai...
Oil and Gas Development: BLM Needs Better Data to Track Permit Processing Times and Prioritize Inspections
GAO-13-572: Published: Aug 23, 2013. Publicly Released: Sep 23, 2013.
Bureau of Land Management (BLM) data indicate that BLM received about half as many applications for permit to drill (APD) for federal oil and gas resources in fiscal year 2012 as it had in fiscal year 2007. The decline in APDs since 2007 was driven by declines in natural gas and coalbed methane APDs on federal lands even while oil development on federal lands increased significantly. The reasons B...
