Paleomorphology of the upper part of the Macae formation, Namorado fieldCampos basin ; Paleomorfologia do intervalo superior da formacao Macae, Campo de Namorado, Bacia de Campos. The Macae Itnroduo Late Albian-Turonian of the Campos Basin is represented by a thick column of carbonate sediments whose chiavenatp began chiavenatoo after the evaporitic phase that marks the beginning of the marine occupation of the basin.
The top of this interval is represented by an unconformity Type Iindicative of a variation in the base level of idalbertk basinon which the turbidities of the basal sequence of the Namorado Field were deposited. For a better understanding of the depositional geometry of these turbidities, the paleogeomorphology analysis demonstrated to be quite efficient. The developed analysis allowed the individualization and the three-dimensional visualization of a sinuous paleochannel in the top of the interval, until then not described in previous interpretations of this depositional system.
With the information coming from this study, a better understanding of the genesis of this accumulation can be reached, especially in the part regarding to the units of important economic character, represented by the turbidities deposits and whose occurrences are related with stages of relative lowering of the sea level.

Magnetic Surveying Techniques are fully used in order to control the well path in drilling operations, and electronic tools, known as Measure While Drilling MWDuses the intensity and inclination of Earth’s magnetic field as a reference for its inputs. These tools have three magnetometers and three accelerometers spaced 90 degrees apart which measure the components of magnetic field and gravitational field to calculate the inclination, the direction of the well, and the tool face orientation.
Erroneous readings can occur due to the magnetic interference since the Earth magnetic field can be affected by external sources such as, magnetized materials in the BHA axialcasings strings or near by wells cross axialand these abnormal readings are enough to put the well bore far away from its desired location.
In this paper we intend to show the methodology and software usage to allow magnetic field strength exam and identification of systematic failures in mechanization or calibration of the electronics tools.
Furthermore, the results obtained comparing the solutions with gyroscope survey data is shown.

Paleoenvironmental changes and influence on Operculodinium centrocarpum during the Quaternary in the Campos Basinsouthwestern Brazil. The purpose of this paper is to document the changes observed in the Quaternary dinoflagellate assemblages from 80 core samples from the Campos Basin. High abundance of Operculodinium centrocarpum suggests the warm, high salinity and nutrient-poor water conditions dominated the upper water column of the Campos Basin.
The climate and oceanic current dynamic of the continental slope of the Campos Basin appears to has been a significant controlling factor in the distribution of dinocysts, particularly of O. Results of the marine biota monitoring during drilling activity on Campos BasinBrazil. The Environmental Monitoring Project PMA aims to report environmental changes arising from drilling activity, in relation to the marine fauna.
This project can also help in the monitoring of accidental spills. Since the professionals spend six hours of the day monitoring the ocean around the rigs, they can locate and identify oil stains, notify the responsible onboard, and also help in the monitoring of the oil stain.

Such Project has been developed onboard a drilling unit working in Campos Basin. The results presented here were collected during the drilling idalbertl in Bijupira and Salema fieldsby Shell Brasil Petroleo Ltda, from July 13th to October 8th, Risk analysis applied to development of a gas field in Santos Basin ; Analise de risco aplicada ao desenvolvimento de um campo de gas na Bacia de Santos.
Decision analysis applied to the development phase of petroleum fields must take into cyiavenato the risk associated to many kinds of uncertainties. In the transition of the appraisal to the development phases, the importance of risk associated to the production and the recovery factor may increase significantly. The process is complex due to high investments, large number of uncertain variables and strong dependence of the results with the production strategy definition.
In E and P, several decisions must be taken considering the risks involved through the appraisal of the uncertainties impact in production of petroleum fieldsincrease the possibility of success, measuring possible lost and sub-optimized developments identifying new opportunities.
In a specific scenario, like gas production, the risk associated to the project becomes larger due to the gas prices compared to oil, the demand, the distribution’s structure and the deadlines defined in contracts. The objective of this paper is to show the results of a methodology developed in a detailed study of a risk analysis process in appraisal and development phases execution and implementation to one of the biggest gas fields in Brazil Mexilhao Field and support reliable future decisions.
Studies were carried out taking into account not only elements of production behavior, but also the geologic aspects of the productive zones.
Among various proposed actions, the following can be outlined: Additionally, the possibility that some wells be systematically producing from some hydrocarbon accumulations in volcanic rocks not classified as reservoir yetwhich is feeding introvuo turbidities reservoirs is also investigated.
The use of geochemical saturation, image and cement logs may lead to identify new oil producing horizons, including non-conventional reservoirs.
In order to support new ideas on reservoir geometry and subsequent modeling, a new seismic acquisition is proposed. Actual stage of organic geochemical knowledge from Campos and Espirito Santo basinsBrazil. Campos and Espirito Santo basins display several similar geochemical aspects.
The microbial and other degradation processes caused changes in the composition of the oils in the reservoir rocks. The oils are biodegraded in different degrees, with the reservoir temperature developing an important role in the control of the biodegradation process. The migration pathway model is similar for Campos and Espirito Santo basinsinvolving the upward secondary migration through a window in the evaporitic seals. The oils passed to the marine sequence where migration and accumulation were controlled by faults, regional unconformities and by reservoirs.
The geochemical correlation of oils are realized by gaseous and liquid chromatography analysis, carbon isotopes and biolabelled compounds. Raft tectonics in northern Campos Basin ; Tectonica de jangada raft tectonics na area norte da Bacia de Campos. This process is known as raft tectonics, and it represents the most extreme form of thin-skinned extension above the salt decollement surface. Three distinct geotectonic domains were recognized that formed in response to the raft tectonics. The first one, confined to the shallower shelf portion of the basinis characterized by minor extension pre-raft domainprobably because of small salt thickness and low gradient.
In the second domain or disorganized rafts domainlocated in distal platformal and slope areas, seismic sections show the occurrence of blocks or rafts with angular shapes, sometimes imbricated and frequently discontinuous. In the third domain, or domain of organized rafts, located in bacinal region, seismic sections show a more continuous raft pattern, often folded because of salt compression in the distal portions of the basin.
The main purposes of this work is to characterize these three tectonic domains distinguished by raft tectonics, as well as their importance in hydrocarbon accumulations in calcarenites. The present conquest of the self-sufficiency is a result of 3 decades of investments that started with the discovery of the well 1-RJS-9A in The second leap was the discovery of giant fields in the including Marlim and Albacora among others.
This first two conquests were basically technical and were recognized by the OTC in and The third leap was the utilization of project finance structures. The financial structures of Albacora, Barracuda, EVM and Marlim are shown and discussed in various aspects which including structure, schedule, conditionalities, warranties, management of the SPEs and relationship with international agencies.
To manage the increasing volume of produced water became one of the main challenges in the petroleum industry. PWRI produced water re-injection leads to a decrease operational cost in platforms, an increase in liquid flow rates on the topside facilities and a decrease in surface disposal of water. Nowadays in Brazilian fields for every barrel of produced oil three barrels of water need to be handled. PWRI is a process that has been widely diffused in many fields in the world.
The main advantages of the PWRI are to reduce collected water, to decrease or eliminate surface disposal of produced water, and to help oil recovery. On the other hand, PWRI tends to increase corrosion when inappropriate materials in tubing and pipelines are used; increase souring potential due to the amount of nutrients for bacteria in the produced water; increase scale formation when sea-water and produced water are mixed and increase formation damage.
Even in reservoirs with good qualities in terms of permeability and porosity, the poor quality of the reinjection water decreases injectivity. To minimize injectivity loss some requirements are important: From obc seismic to porosity volume: A pre-stack analysis of a turbidite reservoir, deepwater Campos BasinBrazil.
The Campos Basin is the best known and most productive of the Brazilian coastal basins. Turbidites are, by far, the main oil-bearing reservoirs. Using a four component 4-C ocean-bottom-cable OBC seismic survey I set out to improve the reservoir characterization in a deep-water turbidite field in the Campos Basin.
In order to achieve my goal, pre-stack angle gathers were derived and PP and PS inversion were performed. The inversion was used as an input to predict the petrophysical properties of the reservoir. Converting seismic reflection amplitudes into impedance profiles not only maximizes vertical resolution but also minimizes tuning effects. Mapping the porosity is extremely important in the development of a hydrocarbon reservoirs. Combining seismic attributes derived from the P-P data and porosity logs I use linear multi-regression and neural network geostatistical tools to predict porosity between the seismic attributes and porosity logs at the well locations.
After predicting porosity in well locations, those relationships were applied to the seismic attributes to generate a 3-D porosity volume.
The predicted porosity volume highlighted the best reservoir facies in the reservoir. The integration of elastic impedance, shear impedance and porosity improved the reservoir characterization. Production strategy and technological challenges arisen with the low permeability gas reservoirs in the Mexilhao, Urugua and Tambau FieldsCampos BasinSoutheast, Brazil; Estrategia de producao e desafios tecnologicos no desenvolvimento da producao de gas nos reservatorios de baixa permeabilidade dos Campos de Mexilhao, Urugua e Tambau, Bacia de Santos.
Besides the contribution to attend the country gas demand the production of these fields starts the establishment of a minimum gas production, transportation and processing infra-structure, that are flexible enough to permit increasing in production from possible upsides. This new production pole has a strategic importance because it will increment gas production close to the main brazilian consumer center.
Digital model of the seabed geomorphology of southern-central Espirito Santo basin and northern Campos basin ; Modelo digital da geomorfologia do fundo oceanico do centro-sul da bacia do Espirito Santo e norte da bacia de Campos.
Unidade de Servicos de Exploracao e Producao], Emails: That communication brings the result of a bathymetric mosaic of converted in a digital model of the ocean topography, consisting of 17 seismic projects 3D, besides 17 multibeam bathymetry surveys of South-Central Espirito Santo Basin and Northern Campos Basin. Water isotopic characterization of hypersaline formation of a petroleum field Reconcavo basinBrazil; Caracterizacao isotopica de aguas de formacao hipersalinas de um campo de petroleo da Bacia do Reconcavo, Brasil.
Formation water is the water present in reservoir rock pores, produced together with petroleum. The concentration of the dissolved elements and the isotopic composition of the water and of some of the dissolved elements can be excellent tracers to study the dynamic of underground fluid flux, the mixing of distinct sources and the origin of salinization of these waters. It is observed an enrichment of deuterium and oxygen with the depth of production zone, probably due to water-rock interactions that were probably increased by higher temperatures of the deeper levels and longer residence times.
The samples from the production zone between to m, drained by 7 of the 10 wells sampled, show a small range in isotopic composition and in electric conductivity, indicating homogeneity in this level of the reservoir. Recent discoveries in the Espirito Santo Basin confirm the importance of it in the national exploratory scenery oil and gas production.
The new fields like Carapo and Camarupim, beyond others, next to already known Golfinho and Canapu, totalize an addition of million barrels.
