  ASSOCIATED 
  HYDROCARBONS. 
  

  

  NATURAL 
  GAS. 
  

  

  Throughout 
  the 
  Santa 
  Maria 
  district 
  wherever 
  any 
  oil 
  has 
  been 
  found 
  

   it 
  is 
  invariably 
  accompanied 
  by 
  considerable 
  quantities 
  of 
  natural 
  

   gas; 
  indeed, 
  this 
  form 
  of 
  hydrocarbon 
  is 
  somewhat 
  more 
  widely 
  dis- 
  

   tributed 
  than 
  the 
  oil, 
  occurring 
  in 
  many 
  places 
  in 
  the 
  shale 
  above 
  the 
  

   oil 
  zones 
  and 
  in 
  some 
  wells 
  which 
  have 
  yielded 
  no 
  petroleum. 
  The 
  pres- 
  

   sure 
  of 
  the 
  gas 
  varies 
  from 
  zone 
  to 
  zone 
  and 
  from 
  well 
  to 
  well. 
  The 
  

   greatest 
  pressure 
  so 
  far 
  recorded 
  was 
  in 
  Hartnell 
  well 
  No. 
  1, 
  where, 
  

   according 
  to 
  Mr. 
  Orcutt, 
  it 
  was 
  over 
  400 
  pounds 
  per 
  square 
  inch 
  dur- 
  

   ing 
  the 
  initial 
  flow 
  of 
  oil 
  and 
  gas. 
  Most 
  of 
  the 
  gas 
  is 
  utilized 
  for 
  the 
  

   generation 
  of 
  heat 
  or 
  of 
  power 
  direct 
  in 
  gas 
  engines. 
  Some 
  of 
  it 
  is 
  

   utilized 
  for 
  domestic 
  purposes 
  in 
  the 
  field 
  and 
  the 
  immediate 
  vicinity. 
  

  

  ASPHALT. 
  

  

  Great 
  deposits 
  of 
  asphalt 
  are 
  associated 
  with 
  the 
  petroleum-bearing 
  

   and 
  later 
  formations 
  over 
  certain 
  portions 
  of 
  the 
  Santa 
  Maria 
  dis- 
  

   trict. 
  The 
  asphalt 
  (in 
  the 
  broader 
  sense 
  of 
  the 
  word) 
  within 
  the 
  

   district 
  occurs 
  in 
  several 
  different 
  ways 
  — 
  as 
  veins 
  penetrating 
  the 
  

   Monterey 
  shale 
  and 
  later 
  formations; 
  as 
  impregnations 
  of 
  the 
  shale, 
  

   sands, 
  or 
  gravels 
  in 
  or 
  overlying 
  the 
  Monterey; 
  and 
  as 
  more 
  or 
  less 
  

   impure 
  effusions 
  at 
  the 
  surface. 
  The 
  more 
  important 
  deposits 
  are 
  in 
  

   the 
  hills 
  northwest 
  of 
  Arroyo 
  Grande; 
  in 
  the 
  region 
  of 
  Asphaltum 
  

   and 
  La 
  Zaca 
  creeks, 
  east 
  of 
  Sisquoc; 
  in 
  Graciosa 
  Ridge; 
  and 
  in 
  the 
  

   vicinity 
  of 
  Redrock 
  Mountain. 
  These 
  deposits 
  have 
  been 
  described
