  EASTERN 
  GROUP 
  OF 
  WESTERN 
  UNION 
  WELLS, 
  

   LOCATION 
  AND 
  STRICTURE. 
  

  

  The 
  eastern 
  wells 
  of 
  the 
  Western 
  Union 
  Company 
  are 
  located 
  near 
  

   the 
  head 
  of 
  one 
  of 
  the 
  branches 
  of 
  the 
  broad 
  valley 
  which 
  extends 
  east- 
  

   northeastward 
  from 
  Harris 
  Canyon, 
  at 
  Blake, 
  and 
  are 
  about 
  5 
  miles 
  

  

  ! 
  southeast 
  of 
  Orcutt. 
  They 
  are 
  from 
  one-half 
  to 
  three-fourths 
  of 
  a 
  mile 
  

   east 
  of 
  the 
  west 
  property 
  line 
  of 
  the 
  company 
  and 
  close 
  to 
  the 
  north 
  

   line. 
  Slightly 
  more 
  than 
  half 
  a 
  mile 
  to 
  the 
  northeast 
  of 
  the 
  wells 
  is 
  

   the 
  axis 
  of 
  the 
  Mount 
  Solomon 
  anticline, 
  from 
  the 
  southwestern 
  flank 
  

   of 
  which 
  the 
  wells 
  derive 
  their 
  oil. 
  The 
  structure 
  in 
  the 
  immediate 
  

   vicinity 
  of 
  the 
  wells, 
  as 
  indicated 
  by 
  the 
  logs 
  (see 
  PL 
  X, 
  p. 
  92), 
  is 
  more 
  

   or 
  less 
  complicated 
  T 
  the 
  general 
  strike 
  of 
  the 
  beds 
  apparently 
  changing 
  

   abruptly 
  from 
  northwest 
  to 
  southwest 
  immediately 
  northwest 
  of 
  the 
  

   group. 
  Furthermore, 
  a 
  local 
  flexure 
  with 
  northeast-southwest 
  strike 
  

   immediately 
  underlies 
  the 
  developed 
  territory, 
  and 
  a 
  pronounced 
  

   anticline 
  (here 
  named 
  the 
  "Western 
  Union") 
  with 
  a 
  steep 
  northeast- 
  

   ern 
  flank 
  lies 
  just 
  to 
  the 
  south. 
  There 
  is 
  no 
  surface 
  evidence 
  of 
  the 
  

   northeast-southwest 
  disturbance, 
  but 
  the 
  Western 
  Union 
  anticline 
  

   is 
  plainly 
  to 
  be 
  seen 
  in 
  the 
  Fernando 
  beds. 
  The 
  dip 
  of 
  the 
  beds 
  on 
  the 
  

  

  I 
  southwestern 
  flank 
  of 
  this 
  fold 
  ranges 
  at 
  the 
  surface 
  from 
  15° 
  at 
  the 
  

   west 
  end 
  of 
  the 
  hill 
  south 
  of 
  the 
  wells 
  to 
  10°, 
  and 
  possibly 
  much 
  less, 
  

   one-half 
  mile 
  to 
  the 
  southeast. 
  The 
  maximum 
  northeasterly 
  dip 
  of 
  

   45° 
  occurs 
  south 
  of 
  well 
  No. 
  18, 
  but 
  the 
  slope 
  rapidly 
  decreases 
  both 
  to 
  

   the 
  northwest 
  and 
  southeast. 
  As 
  nearly 
  as 
  could 
  be 
  ascertained 
  from 
  

   the 
  available 
  data, 
  the 
  production 
  of 
  the 
  wells 
  in 
  this 
  group 
  supports 
  

   the 
  anticlinal 
  theory 
  of 
  the 
  accumulation 
  of 
  petroleum 
  — 
  that 
  is, 
  for 
  

   an 
  equal 
  thickness 
  of 
  productive 
  zone 
  the 
  w^ells 
  near 
  the 
  axis 
  of 
  the 
  

   anticline 
  in 
  the 
  local 
  flexure 
  are 
  more 
  productive 
  than 
  those 
  farther 
  

   away 
  from 
  it. 
  

  

  GEOLOGY 
  OF 
  THE 
  WELLS. 
  

  

  The 
  wells 
  start 
  in 
  soil, 
  but 
  soon 
  enter 
  the 
  clay, 
  sand, 
  and 
  conglom- 
  

   erate 
  layers 
  of 
  the 
  Fernando, 
  which 
  is 
  the 
  surface 
  formation 
  in 
  this 
  

   part 
  of 
  the 
  field. 
  The 
  Fernando 
  beds 
  are 
  penetrated 
  for 
  100 
  to 
  250 
  

   feet, 
  varying 
  with 
  the 
  location 
  of 
  the 
  well, 
  the 
  wells 
  on 
  the 
  north, 
  as 
  

   would 
  be 
  expected 
  after 
  an 
  examination 
  of 
  the 
  surface 
  geology, 
  pass- 
  

   ing 
  through 
  it 
  in 
  the 
  shortest 
  distance. 
  Water 
  and 
  quicksand 
  were 
  

   encountered 
  in 
  at 
  least 
  two 
  of 
  the 
  wells 
  in 
  the 
  lower 
  portion 
  of 
  the 
  

   Fernando 
  ; 
  in 
  another, 
  asphaltum 
  occurs 
  at 
  the 
  base 
  of 
  the 
  formation. 
  

   From 
  the 
  base 
  of 
  the 
  Fernando 
  to 
  the 
  first 
  oil 
  zone 
  the 
  wells 
  penetrate
