Smart Wells

  Sushanta Sarkar  Smart   Wells/Intelligent   Wells   The   generic   term   “ smart    Well”/“intelligent    well” is   used   to   signify    that   some   degree   of    direct   monitoring   and/   or   remote   control   equipment   is   installed    within   the    well   completion     The   definition   of    an   intelligent    well   is   a   permanent   system   capable   of    collecting,   transmitting,   and   analyzing    wellboreproduction   and   reservoir   and   completion   integrity    data,   and   enabling   remote   action   to   better   control   reservoir,    well,   and   production   processes     The   concept   of    the   intelligent   completion   does   not   generally    refer   to   any    capability    for   automated   self  ‐ control   but   relies   upon   manual   interface   to   initiate   instructions   to   the    well  Smart   Wells/Intelligent   Wells   The   long ‐ term   objective   of    the   “intelligent ‐  well   system” is   a    well   (or   several    wells)    with   the   capability    for   automated   self  ‐ control,    without   the   need   to   enter   or   manually    send   instructions   to   the    well,    which   implies   a   closed   loop   between   monitoring   and   control   devices   Downhole sensors   and   control   devices    would,   therefore,   be   combined    with   a   surface   or   subsurface   unit   for   production   optimization
