FEAST Launcher
The Fugitive Emissions Abatement Simulation Toolkit or FEAST is a model to evaluate the effectiveness of methane leak detection and repair (LDAR) programs at oil and gas facilities. Recent advances in the development of new fixed (continuous monitoring systems) and mobile (truck-, drone-, plane-, and satellite-based) methane leak detection technologies have led to growing interest in alternative LDAR programs. The FEAST model helps operators and regulators compare a variety of LDAR program configurations such as continuous monitoring systems and hybrid aerial and ground surveys to develop cost-effective mitigation protocols.

The following five cases show the residual methane emissions after conducting different lead detection and repair (LDAR) programs. Different parameters are used in the five cases including: emission size distribution, survey technology, and survey frequency.
Case 1 - Bridger distribution; OGI (x4 times/year), Aerial_4kg/h (x4, x6, x12 times/year).
Case 2 - Bridger distribution; OGI (x4 times/year), Aerial_10kg/h (x4, x6, x12 times/year).
Case 3 - Bridger distribution; OGI (x4 times/year), Aerial_30kg/h (x4, x6, x12 times/year).
Case 4 - EPA distribution; OGI (x4 times/year), Aerial_4kg/h (x4, x6, x12 times/year).
Case 5 - EPA distribution; OGI (x4 times/year), Aerial_10kg/h (x4, x6, x12 times/year).
