Four distinctive types of crude oil, one of which is. divisible into two subtypes, are present among the fifteen United States Bureau of Mines analyses of Spindletop crude. Types B, C, and D seem indigenous respectively to the Middle Miocene, Lower Miocene, and Oligocene; B is not migrant C or D, and C is not migrant D. Although immigrant into the cap rock, type A is not derived from types B, C, or D. Some of the analyses are from migrant B and C crudes. The change of character of the crude during migration was slight and was mainly in the direction of slight decrease of residuum and of viscosity of the crude as a whole. Stratification according to gravity is shown by type B crude and consists in the main of enrichment of the upper part of the reservoir in the lighter fractions. Increase of the A.P.I, gravity of the crude and of all fractions with increasing depth is shown, and also a tendency toward increase of the lighter half of the distillation fractions.
