Ultimate analysis was conducted for the fossil resin concentrate and results obtained are given in Table 2. Based on these results and other results from spectroscopic analysis it appears that the fossil resin from the Wasatch Plateau coal field consists mainly of aliphatic components and partially aromatized multicyclic terpenoids with a few oxygen functional groups. As compared with the parent high volatile bituminous coal, the resin has higher hydrogen and carbon content, low oxygen, nitrogen, and sulfur contents, and relatively low aromaticity. The values of the acid number and iodine number indicate that the fossil resins from the Wasatch Plateau coal field contain only a modest amount of oxygen functional groups and unsaturated carbon-carbon double-bonds in their molecular structures. Fossil resin is a complex mixture of sesquiterpenoids and the solubility of these resin compounds depends on the type of solvent used. The determination of the extractable resin content in the resin concentrate by different solvents provides an important control variable for selective solvent refining and purification. The data generated during preliminary solvent extraction tests are especially important for process design, control of the refined resin quality and prediction of the refined resin products. In this work, the extractable resin content …

Sierra Energy Company`s targeted goals during the third quarter of this Cooperative Agreement included the following objectives from the Statement of Work: in Phase 2A, completion of subtask 2.1.2--acquire best possible field data in the 3-D seismic program; and initiation of Subtask 2.1.3--process acquired 3-D seismic data. Technical progress is described for these tasks.
