Show Earth Temperature Time Not Pressure Produced Petroleum NEW YORK YORK Heat Heat and time rather ri than great earth pressures now arc are believed to be the mediums chiefly for natural formation of petroleum laboratory experiments made in connection with research projects sponsored by the American Petroleum Institute in an un effort ellort to learn more about the fundamentals of this natural natural nat nat- i ural resource and to determine if and where new sources are available an have bane demonstrated that little oil and gas are produced from such such rocks as us oil on Oil b by pressure alone subjected at nt low or room temperatures I I ures tires to pressure exceeding pounds per square inch for as ns long as asI insignificant I seven sc months yielded quantities Even shale known to contain con con- tain tamu as ns much as ns 44 per cent infiltrated oil failed to release its petroleum content content con con- tent in iii appreciable amount although pressure applied was equal to that at earth depths of 10 to 15 mlles miles Temperatures at ut depths fe feet t below the earths earth's surface are believed sufficiently sufficient high to cause amuse slow distillation distillation tion of oj organic matter mattel Into oil and gas over a u long period but it is estimated that with shale t such uch as ns is found in Utah sonic some years cars would be he required re lC required re- re to convert con as us much as ns one per pOl percent percent cent of ot the line organic matter at a n tem tern of degrees In oil at shallow depths and earth temperatures below that degree it is believed little if it any change will occur in organic matter maUer pressures of themselves e when exerted on oil at nl low room temperatures and through relatively relatively re reo re- re short periods of time do not generate oil from flom the organic matter mutter J.
