SUMMARY REPORT WELL ZT2 & ZT3
LNG TERMINAL - ZEEBRUGE
=============================
I. OBJECTIVE
-------------
To investigate the Yc clay formation as an extension program of well ZT1 (11W0280) for the
possibilty of a gas storage site in LNG-Terminal Zeebrugge by obtaining NON
DESTRUCTIVE samples (Well ZT2) and PRESSIOMETER TEST IN-SITU (Well ZT3).
II. CONTRACTOR
--------------
The drilling job and -
coring for Non-Destructive Samples : SMET BORING NV. (B).
