Abstract

In December 2018, a tracer test was
conducted at pattern area “X” in C- Zone as the
reservoir target of the injection. The injection
pattern is inverted-7 spots, where the injection
well is located in the middle of monitoring wells.
By referring to the mathematical model proposed
by Abbaszadeh and Brigham (1983), a onedimension

modeling of Tracer Elution Curve
Analysis (TECA) was done to describe reservoir
layering characterization in C-Zone (net pay,
porosity, and permeability of each layer). Since
the assumption of TECA’s mathematical model is
that the saturation and the porosity of each layer
have the same value, uncertainty analysis is
required to obtain an overview about reservoir
heterogeneity in the pattern area.The research
begins with data preparation and quality control;
data input to the TECA program; the number of
peak determination as to the function of layer
number or tracer flow unit number from the
injection well to the monitoring wells; streamline
and properties calculation by TECA for each
tracer flow unit; and the uncertainty analysis
using of porosity and water saturation value
sensitivity. The uncertainty analysis shows the
effect of porosity and water saturation change on
the output of TECA. The tracer test analysis by
using one-dimension modeling of Tracer Elution
Curve Analysis has given us an overview of
reservoir connectivity and heterogeneity in the
pattern area. Hence, the output parameters can be
used in waterflooding and polymer injection
optimization.
