The injected fluid should include a range <br />of petroleum products with a shorter carbon chain (C6-12) as in mineral spirits or gasoline in addition to <br />longer carbon chains (C 10-24) as in heating/fuel oil of our permit. <br />This lighter fluid will provide a better heat transfer from our electric heater to the oil shale formation. <br />Please note that the produced shale oil naturally contains significant quantities of mineral spirits, gasoline, <br />and heating/fuel oil. Our retorting and processing contemplates producing and recovering of all of these <br />petroleum fractions. <br />We will obtain the proper material directly from a refinery to be sure of its composition. We will use a <br />tracer as provided for in Section C. 5. of our permit. <br />We contemplate injecting this heat transfer fluid in late May; therefore, your prompt attention to this <br />request will be appreciated. <br />On another matter, following Part II Section A.3.(0 of our permit, the conveniently accessible location for <br />the attachment of a pressure gauge is tens of feet away from the wellhead, but still before any process <br />activities occur. Please concur that this location is acceptable. <br />Sincerely, <br />4141-e? <br />Roger L.
