THE lOLA ARCH 105 



The stratum rises to the westward from this point and does not regain 

 tide level until it is followed about 2 miles beyond lola. At lola its 

 place is calculated to be 37 feet above tide. 



We have thus a stretch of territory about 8 miles in length from east 

 to west in which there is no fall to the Missis^ippian floor of the section. 

 Its normal dip of 17 feet to the mile would carry it 126 feet below tide 

 in that distance. 



The gas rock is not coextensive with the arch, as, it will be remem- 

 bered, it fails to appear in the Edwards well. If it had continued to 

 that point in its normal volume, its upper surface would have been found 

 77 feet above tide. 



At Laharpe, however, it is found in full force, and its surface here is 

 140 feet above tide, as determined by the average of two 905-foot wells. 

 It rises 19 feet higher in the next 3 miles, being found at 159 feet above 

 tide in the Remsberg well. This is the highest point of the lola gas rock, 

 so far as explorations have now gone, and it is interesting to note that 

 this well is the largest producer of gas in the entire field. Its volume 

 exceeds ten million cubic feet a day, which is about three million in 

 excess of any other well in the field. The surface of the gas rock de- 

 scends 43 feet in the next two miles to the westward. The average depth 

 to the gas rock of two wells at lola is 840 feet, which shows its surface 

 to be 116 feet above tide. Within the next two miles the Mississippian 

 limestone gets down to tide level again, and this point marks the limit 

 of the lola arch. 



STRUCTURE AS A FACTOR IN INTERPRETATION 



It is thus seen that the lola gas field comes fully into line with a large 

 number of other gas fields that belong to the same class with it. In all 

 of these, structure is the dominant factor, a factor which helps us to a 

 rational explanation of the characteristic phenomena of all. 



ECONOMIC VALUE 



A word as to the use which is to be made of the lola gas field. It 

 seems certain that it will be devoted in the wholesale way to manufact- 

 uring purposes. The zinc smelters of the Joplin district found their 

 way into the gas field almost as soon as its valuable character was estab- 

 lished. They bought and leased gas lands wherever they could be 

 secured, and thus, without holding a large acreage, they have gained 

 access to all parts of the field. Five or six large plants are already estab- 

 lished here. The experimentation necessary to adapt the fuel to the 

 process has already been successfully accomplished, and the smelters 

 now report the best of results. Others are sure to come in to secure the
