PENNSYLVANIA CRUDE OIL, SP-42 Appalachian Basin, Pennsylvania and Michigan Basin, Michigan.  Two crude oils consisting of saturated paraffin hydrocarbon compounds available - light (sweet) and heavy (sour).  Pennsylvania Crude is mostly a light sweet crude that does not have the high levels of sulfur that other crude oils have.  Available in 4 mL, 40 mL, 100 mL and 250 mL bottles.  The "sour" heavy crude is also available from the Michigan Basin.  We will be updating the petroleum section soon.  Not all sizes available for every type.  Inquire.  New sizes.  (Ask about new types and locations -  Basrah Light from the Zubair Zone, Iraq; Arab "D" Zone and Lower Ratawi Zone in Saudi Arabia; etc.  These new types vary in size and price.  We also now have extra light and extra heavy.)

 

40ml bottle - $4.00 each    100 mL - $8.50 each      250 mL $16 each

 

 Detailed explanation included of content and difference between petroleums.  Smaller two-bottle sets of one each type also available until stock runs out, 4 mL each, (1 sweet and one sour), but check availability.  Small set of two 4 mL bottles is $6.  These oils work well in a "fossil fuel" unit using oil shale and oily sandstone for the petroleum series; may also compare it to the coal fossil fuel series, using peat and the three coals - lignite, bituminous, and anthracite.
