﻿DETAILS 
  OF 
  THE 
  DEVELOPED 
  TERRITORY.

  Between 
  the 
  first 
  zone 
  and 
  the 
  one 
  that 
  has 
  been 
  recognized 
  as 
  the 
  

   second, 
  or 
  zone 
  B, 
  are 
  one 
  or 
  more 
  productive 
  zones 
  2 
  to 
  15 
  feet 
  thick. 
  

   No 
  two 
  wells 
  show 
  the 
  same 
  sequence 
  of 
  these 
  zones 
  and 
  they 
  prob- 
  

   ably 
  represent 
  places 
  of 
  local 
  fracturing. 
  

  

  The 
  second 
  oil 
  zone 
  (B) 
  is 
  thought 
  to 
  be 
  fairly 
  constant 
  through- 
  

   out 
  the 
  area. 
  It 
  consists 
  of 
  alternating 
  barren 
  and 
  productive 
  layers 
  

   of 
  shale, 
  some 
  of 
  the 
  productive 
  layers 
  being 
  from 
  a 
  few 
  feet 
  to 
  as 
  

   much 
  as 
  20 
  feet 
  thick. 
  Below 
  the 
  main 
  or 
  upper 
  part 
  of 
  this 
  zone 
  

   are 
  other 
  productive 
  layers, 
  some 
  at 
  least 
  200 
  feet 
  below 
  zone 
  B. 
  

   The 
  oil-bearing 
  measures 
  in 
  these 
  zones, 
  as 
  in 
  zone 
  A, 
  are 
  probably 
  

   nothing 
  more 
  or 
  less 
  than 
  fractured 
  portions 
  of 
  the 
  shale. 
  

  

  PRODUCT. 
  

  

  The 
  oil 
  from 
  the 
  wells 
  in 
  this 
  area 
  runs 
  from 
  24° 
  to 
  26° 
  Baume, 
  and 
  

   is 
  dark 
  brown 
  in 
  color 
  with 
  the 
  exception 
  of 
  that 
  from 
  one 
  of 
  the 
  

   wells, 
  which 
  is 
  said 
  to 
  be 
  a 
  reddish 
  emulsion 
  of 
  oil 
  and 
  water. 
  All 
  

   the 
  wells 
  show 
  much 
  gas, 
  the 
  best 
  producers, 
  especially, 
  being 
  under 
  

   heavy 
  pressure. 
  

  

  The 
  production 
  of 
  the 
  individual 
  wells 
  in 
  this 
  group 
  ranges 
  from 
  

   an 
  initial 
  output 
  of 
  12,000 
  barrels 
  per 
  day 
  in 
  one 
  well 
  to 
  a 
  daily 
  aver- 
  

   age 
  of 
  150 
  barrels 
  in 
  another. 
  The 
  following 
  statement 
  concerning 
  

   the 
  production 
  of 
  Hartnell 
  well 
  No. 
  1, 
  the 
  greatest 
  producer 
  in 
  the 
  

   California 
  oil 
  fields, 
  has 
  been 
  kindly 
  furnished 
  by 
  Mr. 
  Orcutt, 
  of 
  the 
  

   Union 
  Oil 
  Company: 
  

  

  Well 
  (Hartnell 
  No. 
  1) 
  started 
  to 
  flow 
  over 
  derrick 
  through 
  8^-inch 
  and 
  between 
  this 
  

   and 
  10-inch 
  casing 
  December 
  3, 
  1904. 
  Gas 
  pressure 
  was 
  very 
  heavy, 
  estimated 
  at 
  400 
  

   pounds 
  per 
  square 
  inch 
  — 
  was 
  probably 
  much 
  higher, 
  however. 
  Oil 
  was 
  measured 
  in 
  

   an 
  open 
  ditch 
  by 
  use 
  of 
  a 
  miner's-inch 
  measuring 
  box, 
  and 
  showed 
  31 
  miner's 
  inches, 
  

   or 
  about 
  12,000 
  barrels 
  per 
  day. 
  The 
  flow 
  continued 
  for 
  about 
  sixty 
  days 
  and 
  gradu- 
  

   ally 
  weakened. 
  September 
  1, 
  1905, 
  the 
  well 
  was 
  doing 
  3,069 
  barrels 
  per 
  day. 
  

  

  The 
  oil 
  was 
  stored 
  in 
  earthen 
  reservoirs, 
  and 
  the 
  production 
  to 
  the 
  above 
  date 
  is 
  esti- 
  

   mated 
  at 
  1,500,000 
  barrels 
  from 
  this 
  well 
  alone. 
  Up 
  to 
  August 
  15, 
  1906, 
  the 
  total 
  pro- 
  

   duction 
  for 
  the 
  well 
  was 
  something 
  over 
  2,000,000 
  barrels. 
  

  

  The 
  gas 
  accompanying 
  the 
  initial 
  flow 
  of 
  oil 
  was 
  estimated 
  at 
  4,000,000 
  cubic 
  feet 
  

   per 
  day. 
  After 
  the 
  well 
  had 
  been 
  gotten 
  under 
  control 
  it 
  furnished 
  gas 
  for 
  running 
  

   20 
  boilers 
  for 
  well-drilling 
  rigs, 
  and 
  in 
  addition 
  supplied 
  the 
  town 
  of 
  Orcutt 
  (popula- 
  

   tion 
  about 
  200) 
  with 
  gas 
  for 
  domestic 
  purposes. 
  At 
  the 
  present 
  time 
  it 
  is 
  still 
  yielding 
  

   a 
  constant 
  flow, 
  which 
  is 
  used 
  for 
  many 
  purposes 
  in 
  Orcutt. 
  

  

  GRACIOSA-WESTERN 
  UNION 
  AREA. 
  

   LOCATION 
  AND 
  STRUCTURE. 
  

  

  The 
  wells 
  at 
  the 
  northeast 
  corner 
  of 
  the 
  Graciosa 
  and 
  northwestern 
  

   corner 
  of 
  the 
  Western 
  Union 
  properties 
  are 
  located 
  on 
  the 
  point 
  of 
  

   the 
  ridge 
  which 
  runs 
  southward 
  for 
  more 
  than 
  a 
  mile 
  from 
  the 
  main 
  

   Graciosa 
  ridge. 
  The 
  structure 
  of 
  the 
  beds 
  underlying 
  the 
  devel- 
  

   oped 
  area 
  is 
  apparently 
  simple, 
  as 
  they 
  are 
  on 
  the 
  southwestern 
  

   flank 
  of 
  the 
  hypothetical 
  Newlove 
  anticline.
