Summary: | Area 14 is a part of North Duri Development field that have dimensional: 6.2
X 0.9 squares Km with total 65 wells which 14 wells are producing as primary
recovery right now.
High Water Cut and PBTD (Plug Back Total Depth) set of almost actives
wells become a crucial problem in Area 14.
Almost well Log data in area 14 have standard curves like: Gamma Ray (GR)
and Resistivity only. There is only one well has completed logs and continuous core
namely EDJ-A12.
Oil Water Contact (OWC) in well EDJ-A12 can be defined based on reading
of Sw curve and decreasing of Resistivity curve value from the core sample analysis
that have depth on -660 feet of the True Vertical Depth Sub Sea (TVDSS).
Oil Water Ratio Map can be created based on OWC line that across to base of
each reservoir sands are P2, P3, P4 and P5.
Percentage of the high Water cut values can be shown based on overlay the
OWC depth contour Map with PBTD of 14 production wells. Actually only one well
(3P-75A) that has lower water cut (27%) because the PBTD set above from OWC.
On the other hand for other 13 wells have PBTD set on bellow OWC with average
Water Cut values of each well more than 60 %.
