Within the final 10 years the area has come to some degree the place the simply explorable oil deposits have now been discovered, and it truly is expected that such deposits may be depleted by way of the start of the Twenty-first Century. although, the expanding call for of guy­ sort for strength has brought on technologists to appear into methods of locate­ ing new assets or to reevaluat:e unconventional assets which, some time past, haven't been reasonable. during this appreciate, heavy crude and tar sand oils have gotten vital in gratifying the world's power specifications. What are heavy crude and tar sand oils? there's nonetheless a few confusion as to their definitions, inasmuch as they range between companies and nations. so that it will set agreed meanings, UNITAR, in a gathering in February 1982 in Venezuela, proposed the subsequent definitions (see additionally desk 1): 1. Heavy crude oil and tar sand oil are petroleum or petroleum­ like drinks or semi-solids clearly taking place in porous media. The porous media are sands, sandstone, and carbonate rocks. 2. those oils can be characterised via viscosity and density. Viscosity could be used to outline heavy crude oil and tar sand oil, and density (oAPI) might be used whilst viscosity measurements aren't on hand. three. Heavy crude oil has a gas-free viscosity of 100-10000 mPa.s (cp) three o at reservoir temperatures, or a density of 943 kg/m (20 API) three o o to a thousand kg/m (10 API) at 15.6 C and at atmospheric oressure.

21 tends to show that the material used in these experiments was highly variable. Ten runs were made with Batch No. 2 and 25 runs with Batch No. 3 out of a total of 44 runs. 1 wt% tar. The molecular weights of the tar oil extracts show a similar large variance, and these data are believed to be the least accurate. he freezing point depression is measured on only one concentration of the solute in benzene. In any case, the molecular weights were not relied on for any purpose; all compositions were obtained by direct weighing of the tar and careful volumetric measurements or weights of the pure solvents.

Thus the so-called "paraffin deposits" in tubing are really a mixture of various molecular structures depending on their distribution in the original oil. " For example, if one injects propane into a heavy oil reservoir he will almost certainly plug up the well by heavy precipitation because the mixtures formed in the injection well area will all be high concentrations of solvent above the maximum. One way to avoid this is to inject propane in a carrier gas of methane.
