Oil shale project run summary large retort run L-1

L-1, a Modified In-Situ run, was performed in the 0.9 x 6.1 m retort on April 12 to 16, 1977. The retort charge was Anvil Points shale. L-1 showed that reasonable oil yields (72% of Fischer assay) can be achieved even from rubble beds which induce complex nonuniform gas flow patterns. (DLC)
