dioxidesaturated water solutions having ionic composition and conc.close
to that of produced water, as well as API classificationJ-55 tubing steel,
are presented.
Parameters like temperature,partial pressure of CO2 and
ioniccomposition at both static and dynamic conditions that mightaffect
corrosion process have been examined. Significantinfluence of sample
exposure time and electrode stabilizationtime have been confirmed.
Electrochemical methods ofpotentiodynamic and linear polarization and mass
loss method wereused.
Additional tests were performed under elevated temperature andpressure
conditions, close to actual well conditions. Highpressure
autoclav("Sotelem",France) and computerized potentiostat/ galvanostat unit

Summary: Feasibility study of miscible tertiary CO2-process has
beenmade based on data from long-term laboratory studies of CO2potential in
major oilfields in Republic of Croatia.
The paper presents the most significant experimental PVT,slim tube,
core displacement and reservoir simulation data,pertinent to CO2-process
evaluation. Laboratory data were used inregression based tuning of
Peng-Robinson EOS, which wasincorporated into COMP 3, 3-D compositional
simulator (SSI,Inc.)of "Gama-2/4" formation,Ivanić Grad oilfield. A suite
ofcalculations performed includes history matching followed bysimulation of
tertiary CO2-process. Inverted 5-spot injectionscheme was employed.
different WAG schemes were investigated interms of tertiary oil recovery
vs. specific CO2 consumption andtime period needed for repressuring.

Summary: A combination of polymer coating and corrosion inhibitors
has been often an economical solution of the problem of steel corrosion in
CO2 environment, encountered in CO2-injection oil recovery processes.
This paper presents the results of the corrosion protection study of
imidazol (A) and a commercial inhibitor (B) in the system: carbon steel
J-55 + chloride/carbonate solution. Tests were performed under ambient
(A,B) and elevated (B) p,T-conditions employing mass loss method and
potentiodynamic polarization method.
The results indicate that A is not acceptable as corrosion inhibitor,
while B exhibits a strong corrosion inhibiting effect under test
conditions, but is not protective against local corrosion.

Summary: Pipeline or tank transportation of paraffinic cride oils
requires modification of their flow properties (pour point and viscosity).
Addition of specific additives (flow-improvers) is widely used method. The
selection and application of a particular additive requires that oil
physico-chemical characterization and additive testing data are obtained
first. Laboratory testing of flow improver efficiency has to take into
consideration technological parameters of crude transportation process.

Summary: Relative mobilities of gas and oil phases are important
factors that affect oil displacement efficiency during a gas injection
process. In this paper, laboratory apparatus, constructed for study of CO2
mobility control by in-situ generation of CO2-foams is described and
methods of simulation of tertiary oil recovery process are presented. In a
number of experiments residual oil was displaced by CO2 from cores at
reservoir p,T-conditions, using CO2-foams of different quality and various
linear velocity.
The results obtained indicate higher oil recovery under conditions of
CO2 mobility control by CO2-foam formation.

Summary: The objective of this experimental study was to investigate
the potential of pressure maintenance schemes using dry natural gas and
carbon dioxide injection into a deep, hot rich-gas condensate reservoir.
The study included detailed compositional and PVT characterization of
original and partially depleted reservoir fluid, generated by constant
volume depletion (CVD). Mixtures of depleted condensate fluid and dry
natural gas or CO2 were prepared and mixture phase equilibrium data
determined in terms of saturation pressures, composition and retrograde
liquid condensation. This in turn provided the information on the extent of
retrograde revaporization of condensate liquid upon addition of a
particular gas.
The results - reported in terms of respective pressure-composition and
pressure-retrograde liquid dropout diagrams - show that carbon dioxide is
more effective in vaporizing hydrocarbon liquids of the gas condensate
system investigated.

Summary: High resistance of austenitic steel determines its
largeapplication in chemical, food and pharmaceutical industry.Welding
technology is very important in plant construction. Heatproduced by welding
can create undesirable structural phases,which change the structure and
affect mechanical properties andcorrosion resistance.
In this work it has been attempted to investigate theinfluence of
various welding procedures (plasma and TIG) andvarious heat input on the
mechanical properties and corrosionresistance of welded austenitic steel
Č-4580(W.Nr.1.4301). Theresults of investigations, including structural
analysis, haveshown that corrosion resistance of welded austenitic steel
doesnot depend only on corrosive medium but also on the weldingprocedure.

Summary: Presented in the work is current potential and exploration
area of the Republic of Croatia, which is divided into 3 basins: Oannonian,
Dinarides and Adriatic. The most explored is Pannonian Basin, where most
most oil and gas reserves have been discovered and are being produced. Gas
reserves, found in Adriatic Basin have not been exploited for economic
reasons. Perspective areas in foreign countries are also being explored and
significant oil and gas reserves have been found. Secondary methods
(waterflooding) are being successfully applied in our oil field with the
resultant increase of oil recovery.
Two main products, oil and gas, are basis for the production of fuels
and raw materials for petrochemical industry. The major part of those
products is directly included into energy resources of Republic of Croatia,
supplying more than 50% of total energy requirements in Croatia.

Summary: Corrosion activity of water samples from producing
geothermal well in a suburb in Zagreb was experimentally investigated. The
corrosion tests were performed under well p,T-conditions (80 C, 5 bar, H2S
and CO2 present in solution). The results obtained indicate increased
corrosivity of water in contact with carbon steel. Subsequent tests of
several inhibitors (passivating type) show that high degree of protection
can be achieved in the case studied.

Summary: The subject of the thesis is a study of applicability and
feasibility of two possible IOR processes in partially depleted Žutica
A-series oil field.
In theoretical section a detailed procedure of mathematical modeling of a
multicomponent hydrocarbon mixture phase behaviour using equation of state
is presented. The methodology presented is subsequently, in next chapters,
applied to modeling of Žutica reservoir fluid using Peng-Robinson EOS.
Simulation of two IOR processes were performed using the PR fluid model:
1) pressure maintenance scheme using produced field gas
2) gas storage process
The results obtained favor the use of the reservoir for gas storage, due to
additional produced gas enrichment effects.
Keywords: gas recycling, equation of state, phase behavior, gas storage, oil recovery, gas cap
