HYNER  GAS  POOL,  CLINTON  COUNTY,  PA. 
By  M.  L.  Fuller. 
The  Hyner  gas  pool  is  of  interest  as  being  one  of  the  newest  and 
most  easterly  of  the  gas  pools  of  Pennsylvania.  It  is  located  on  the 
West  Branch  of  Susquehanna  River  between  Hyner  and  Ritchie 
stations,  on  the  Pennsylvania  Railroad,  in  the  central  portion  of  Clin- 
ton County.  The  two  stations  are  about  3  miles  apart,  the  gas  wells 
being  about  midway  between  them,  or  at  the  point  where,  according 
to  the  second  geological  survey  of  Pennsylvania,  the  crest  of  a  notable 
anticline  crosses  the' river. 
The  first  well  in  the  region  was  located  one-half  mile  southeast  of 
Hyner,  or  about  a  mile  north  of  the  crest  of  the  anticline.  It  was 
drilled  in  1877,  before  the  anticlinal  theory  of  the  occurrence  of  gas  and 
oil  had  been  extensively  exploited,  but  its  situation  was  more  favorable 
than  that  of  most  of  the  "  wild-cat"  wells  of  northern  Pennsylvania. 
Gas  was  encountered  at  several  horizons,  both  in  the  Catskill  and 
Chemung  rocks,  as  were  also  traces  of  oil.  Some  of  the  gas  flows  were 
fairly  strong.  The  principal  gas  flows  were  from  beds  with  tops  at 
242,  294,  585,  and  1,207  feet,  while  the  oil  shows  were  from  beds  at 
715,  1,207,  and  1,601  feet.     The  well  was  1,983  feet  deep. 
The  shows  of  oil  and  gas  encountered  in  the  early  well,  together 
with  local  conditions  which  appealed  to  the  operator,  finally  in  1903  led 
to  the  drilling  of  a  second  well  by  the  Interstate  Development  Com- 
pany. This  well  was  started  May  16  and  was  drilled  to  a  depth  of 
about  2,000  feet,  when  the  tools  were  lost.  The  tubing  was  completed 
on  August  31. 
The  well  is  notable  as  having  been  located  on  scientific  lines,  the 
aim  being  to  develop  the  pool  on  the  anticline  principle.  It  is  located 
almost  exactly  at  the  crest  of  the  Hyner  anticline  as  mapped  by  the 
Pennsylvania  survey.  The  well  starts  in  Catskill  rocks,  200  feet  of 
which  are  here  brought  to  the  surface  in  outcrops  which,  according  to 
H.  M.  Chance,  are  among  the  most  northwesterly  exposures  of  Catskill 
red  rock  in  the  State.  From  the  vicinity  of  the  well  the  rocks  dip  both 
north  and  south  at  a  rate  of  not  far  from  200  feet  to  the  mile,  dis- 
appearing from  the  surface  near  Hyner  on  the  north  and  near  Ritchie 
on  the  south.  The  red  rocks,  on  which  the  differentiation  of  the
