One of the important activities of the oil industry is drilling for exploration and prospection, during this activity drilling fluids are used and later are formed as waste large volumes called drill cuttings. When inverse emulsion fluids are used it is common to use diesel light oil which increases the content of hydrocarbon impregnated drill cuttings. The aim of the research was to evaluate the concentrations of BTEX and PAH present in sediments associated with oil drilling cuts an environmental liability in southeastern Mexico. Within the dam, the unique values of BTEX were recorded in sediment, they were presented in well PM2 levels 1 and 2 deep. In relation to PAH levels in the dam cuts, only five compounds of this group were presented with the following maximum concentrations: Naphthalene 24.3, Acenaphthene 12.9, Fluorene 14, Phenanthrene and Pyrene 44.7 2 mg / kg. While in exploration wells, located in the dam adjacent to the outer area, BTEX and PAH concentrations nor were presented, both in sediment samples as in ground water. Situation attributed to the mudecake phenomenon of the walls of the dam, due to the precipitation of PAH and material flow in function to the size from the sand, silt and end clays end of sealing the pores of the walls. Finally produce an effect of trapping of these materials in the oil drilling cuts dam, a situation that has avoided adverse effects on the environment directly and indirectly to the biota in the area.
