...-mat oil were analyzed in a laboratory, and novel recovery techniques were developed. On the basis of experimental recovery results, a new strategy for characterizing tar-mat oils was applied, the tar-mat reserve was estimated and oil recovery economics were analyzed.

.... When producing heavy oil, the high viscosity is a major impediment to recovery. Oil viscosity is often correlated directly to the reserves estimate in heavy-oil formations and can determine the success or failure of a given enhanced-oil-recovery scheme. As a result, viscosity is an important parameter...

However, since the database was used for design and planning, the records should still have reflected reasonable reserves estimates. A reduced database was created for each of light/medium oil, heavy oil, and gas. The light/medium oil...
