Cretaceous and Tertiary petroleum systems in the Catatumbo basin (Colombia)
Authors J. Navarro Comet and A. Alaminos MartinezIt is known that around 90% of the world’s hydrocarbons have been generated by a relatively small
number of ultra-rich source intervals deposited during specific periods of geological time. Many mechanisms
have been proposed to explain this particular stratigraphic source rock distribution (oceanic anoxia,
biologic evolution, global climate changes, etc), but its origin is still in debate. It is clear that basins where one
or more of these world class source rocks are present (e.g.: northwest South America, central North Africa)
makes them extraordinarily prolific. However, in most cases all the hydrocarbons found in those areas are
systematically considered to be uniquely sourced by these ultra-rich intervals, neglecting the importance of
other apparently less relevant organic-rich intervals.

Integrated Surface-Downhole Acquisition Geometries – The Way To Higher Detailed Reservoir Investigation
Authors A.A. Tabakov and K.V. BaranovThe increasing demand for detailed exploration of small hydrocarbon deposits and complicated structures
can not always be met by means of conventional seismic surveys such as surface 2D or 3D seismic or
standalone VSP as they feature a number of principal limitations.

Implementation Of The DIPSCAN Method To Estimate Boundary Dips In Complicated Structures By VSP Data
Authors A.A. Tabakov, V.N. Ferentsi and H. GraviniThe knowledge of velocity model not even along well but at offset is key for building of VSP-CDP image
and tie of VSP and surface seismic data. And the task is more difficult in situations of lateral variations of the
media properties, that very typical for highlands. The quality of obtained image is in a straight dependence on
quality of reference model. And it is the main reason to obtain adequate reference model for offset-VSP
processing.

DDR: The Technology Of Simultaneous Wave Field Analysis And Velocity Model Reconstruction
Authors A. Reshetnikov, A. Tabakov, A. Mukhin and V. EliseevThe technology of VSP data processing by means of DDR (Dynamic Decomposition of the
wave-field and Reconstruction of the media) technique consists of several procedures:
1. Construction of the first approximation to
model as a result of kinematical inversion of travel
times and polarizations for visually correlated
events in original data.
2. The synthetic wave parameters are
calculated by ray-tracing method for strongest
event.
3. The estimation of the form of a wave along
calculated arrival times-graph with use of designed
distribution of amplitudes and polarization is
carried out.
4. The located wave is subtracted from an
initial wave field and is projected to the points of scattering on the image section. The waves of
various types from the same point of boundary are stacked with weights proportional to their original
amplitude. The process is repeated for all types of waves and all boundaries until all regular events
are subtracted and projected on section. Not only primary waves, but also multiples may be used in
the process. After imaging the basic model can be corrected and the process may be repeated until
the image will correspond to model with necessary accuracy.

Principles and Techniques of VSP Data Processing
Authors A.A. Tabakov and V.N. FerentsiVertical seismic profiling (VSP) is a popular seismic exploration technology that has been confirmed to be
really efficient for solution of various geological problems even in very complicated conditions. The way
to achieve this and take all of the VSP advantages (such as efficient velocity model recovery, direct impulse
shape estimation and zero-phase deconvolution, detailed surface-borehole tie, high-resolution imaging
and dynamic inversion) is to implement correct processing techniques. In this paper we present key principles of VSP data
processing yielded and inherited as a result of more than 40 years experience in borehole seismic. These
principles form the concept of model based processing technology which includes state-of-the-art developments
and is aimed at high quality and reliability of the acquired results. Demonstrated case histories show examples of
efficiency of the presented technology of VSP data processing.

The Ucayali Subandean Basin: A Complex Fold And Thrust Belt And Inverted System
Authors W. Hermoza, P. Baby, N. Espurt, E. Martinez and R. BolañosThe subandean Ucayali Basin is an active fold and thrust belt propagation, which constitutes part of the
wedge-top depozone of the Peruvian Amazonian retroforeland basin system. In the North, the Ucayali
Basin is limited from the Marañón basin by the NW-SE overthrust Contaya Arch. In the east, the Ucayali Basin
reaches the NNW-SSE trend of the Brazilian Moa Divisor structure, which disappears progressively to the
south on the northern flank of the Fitzcarrald Arch.

Integrated 3D seismic data modeling and processing methodology for structural model analysis: Case study
By T. SalinasThe combination of abrupt topography, complex near-surface and sub-surface conditions, and a
significant tri-dimensional component make the Foothills of Colombia an extremely challenging area for seismic
activities. These characteristics are responsible for the absence of high-quality seismic data on these areas and
therefore, they ask for alternative strategies of seismic data processing, modeling and interpretation.

Rigorous And Innovative Risk Quantification For Basin Modeling
Authors A. Medina, J-M. Laigle and M. PontetAssessing petroleum systems using deterministic basin modelling techniques are
nowadays widely used. Such evaluation has a critical impact on strategic decision with both
economical and technical consequences. Decision makers need to rely on the outcomes
of basin models whose main results should therefore feature a probabilistic distribution
expressing the associated risk.

Cuenca Neuquina, Argentina Relevamiento geoquímico de superficie en trampas estratigráficas
Authors L. Alvarez, D.C. Malizia and Y.M. Graciela PrestíaNeuquen Basin, Argentina. Geochemical Survey in Stratigraphic Traps.
This area presents some difficult challenges to the continued development of this field because of its
structural complexity caused by intense fracturing due to the intrusion of many andesitic sills and dikes.
The results showed that the areal extend of the microseepage anomaly at the surface identified in the
North part of the area approximates the extent of the reservoir, represented by an eolic sandstone deposit.
Also, Low Microseepage value is related to the decrease in the quality of the reservoir.

Subsidence and Geodynamic Analysis Of The Llanos Basin: Linking Mountain Building and Basin Filling Processes
Authors G.Y. Ojeda, G. Bayona, J. Pinilla, M. Cortés and N. GambaSubsidence analysis is a common technique used by the oil industry for definition of the thermal maturity of
source rocks. Here, we performed subsidence analysis via 1D and 2D backstripping to reconstruct the geometry
of a foreland basin (Llanos Basin) that resulted from flexural deformation associated to the growth of an
orogenic belt (Eastern Cordillera). Examples from two regional cross sections illustrate this foreland basin -
orogenic belt coupled evolution.

Vp/Vs Ratio from Three Component Zero Offset: An Additional Tool for Pressure Prediction Ahead of the Bit
Authors C. Planchart and A. PalaciosRisk reduction is an important matter for exploratory wells. Pre-drill pressure forecasting is
usually performed from seismic derived velocities, offset well information and basin fluid flow
modeling. Still there is a significant uncertainty level about the stress regimes ahead of the bit;
therefore it is necessary to refine the estimation of pore pressure ahead of the bit.

A New Page in the History of Reservoir Characterization in the Andes Sedimentary Basin Area, with the Introduction of State of the Art LWD Formation Evaluation Services
Authors A. Carvalho, J. Sierra, L. Sanchez, R. Medina, M. Cevallos, W. Gonzalez and R. SantacruzThe continuous increase in demand of HC resources and the exhaustion of the simplest
reservoir deposits have forced the oil industry to focus on the development of more complex
reservoir targets and drilling profiles. This scenario becomes even more challenging in Sub-Andean
sedimentary basins, given the diversity of depositional environments and the active history of
tectonic stresses that brings into view the additional complication of drilling safety.

Drilling Sweeps Optimization Based On Downhole Measurements
Authors Y. Arevalo, R. Harmer and J. PalacioHole cleaning is an important consideration when drilling any type of well and it becomes more
difficult as hole angle increases. Drilling sweeps are used to improve the removal of solids from the
wellbore. However, the indiscriminate use of sweeps can often lead to higher costs and even
hamper hole cleaning if not used properly. Selection and use of sweeps is historically carried
out using local experience and qualitative indicators.

Tectonic Evolution And Preservation Of Relict Structures In A Triangle Zone: The Tácata Triangle Zone (Maturín Basin, Eastern Venezuela)
Authors O. Férnandez, M.C. Morales, K. Parra and N. SantiagoThe Tácata structure in Eastern Venezuela is a vertical stack of south- and north-verging thrust sheets
within a triangle zone. The Tácata trend evolved as an interplay of regional plate-driven compression and
critical-taper driven thrusting. As a result, it records the relatively stationary deformation front of the Serranía del
Interior fold-and-thrust belt in this area from the Early Miocene to present day. This led to the preservation of
relict triangle zone structures, a unique feature in thrust belt deformation fronts, where relict structures are
commonly exhumed and eroded.

Structures Growing And Decollement Level Role In The Sub Andean Zone Of Bolivia. Caipipendi Block.
Authors I. Moretti, J. Letouzey, A. Otero and J.C. CalvoThe Sub Andean Zone of Bolivia is a very prolific exploration zone. During the last ten years, the
exploration targets have changed. Numerous oil fields have been discovered in the years 70-90 in the
Carboniferous and upper Devonian in the foreland and easternmost emerging anticlines but the exploration get
now more active westward with deepest targets in the lower Devonian. The existence of this petroleum system
was proven since the discovery of the San Alberto field (San Alberto-X9 in 1990), but the deep prospects in the
south SAZ are much targeted only from 10 years. In addition on the cost of the deep wells, moving westward
also means steeper anticlines and poor resolution of the seismic images. For the geologists however, the more
challenging issues come from the fact that the target is now below an important decollement level, the middle
Devonian shale of the Los Monos Fm.
