Dead Oil. The name given to a mixt consisting chiefly of coal-tar hydrocarbons. It was used in Amer blasting expl Rackarock as a partial replacement of NBz Ref Thoq>e4 (1940), 545... 

The same expl was prepd with nitronaphtha-lene, which was less expensive than NB. A subsequent Rack-a-rock Special expl formulation consisted of Rack-a-rock in which the NB was wholly or partially replaced by dead oil (a mixt of coal-tar hydrocarbons), and to this was added from 12 to 16% PA Refs 1) Marshall 1 (1917), 379 2) Ramsey... 

As with liquid systems, the general effect of pressure on phase behavior is negligible (Nelson, 1983). In practice, dead oils are used in phase behavior tests. Therefore, pressure effect is not investigated, although the reservoir temperature is maintained in phase behavior tests. However, different pressure causes a different amount of gas dissolved in the oil. In such cases, the pressure would have some effect. High-pressure PVT cells are needed for such phase behavior tests. 

Distillation of the crude tar yields two groups of products (1) Complex mixtures resulting from fractional distillation and being sold under the names of solvent naphtha, light oil, dead oil, creosote oil, and anthracene oil (2) coal-tar crudes such as benzene, toluene, naphthalene, anthracene, and the less important cumene, carbazole, cresols, and pyridine. Coal-tar intennediates are prepared by purification of these crude products and are used in the manufacture of dyes and other products.

Figure 1 shows the absolute concentrations in dead oils and condensates of several major geo-chemically usable compound types in 351 petroleums covering the full range of maturities found in petroleum system fluids. Samples suspected of biodegradation were filtered out based on light hydrocarbon and n-alkane isoprenoid parameters.

Downstream processing of the oil is more complicated than for produced water, as cost-effective pressure reduction versus compression work has to be considered alongside oil/water separation. The objective of the downstream oil processing is to provide the necessary quality required for shipping/transporting, usually known as stock tank oil or dead oil. Normal requirements are less than 0.5 Wt %...

Initially, the known amount of tank oil was taken into the recombination cell. The dead oil was recombined at 1705 psia and 80°F. The composition of live oil is given In Table 3. The solvent (CO ) was then Injected from the solvent transfer cell into the recombination cell (which also acted as asphaltene cell) at constant pressure. The amount of CO injected was determined from the pump reading. The resulting CO2-0II mixture was rocked for several hours to achieve good mixing. The mixture was then passed through a high pressure stainless steel... 

Run 1 was conducted using waterflood alone. No gelation or any other chemical agent was used in this run. As expected, the water breakthrough took place very quickly. At the end of the displacement test, only 7% of the olMn-place was recovered. For the sake of comparison, oil recoveries at 5% oil cut were used as standard values. Note that in this experlmentation,dead oil was used. Consequently, this 7% recovery does not include any production through primary depletion which is likely to happen in a pressurized reservoir. Results of this run show why displacement-type recovery has not been used in naturally fractured reservoirs. 

Cresote n. Heavy, high boiling oil obtained from coal and wood tars. A major use for creosote is as a wood preservative, or as a base for the same. Syn dead oil and pitch oil.
