Keynote: Fluids expelled tectonically and their role in hydrocarbon migration
Time : 10:00-10:35
Biography:
Katarzyna JarmoÅ‚owicz-Szulc (Assoc. Prof.) has been a scientific worker in Polish Geological Institute – National Research Institute in Warsaw, Poland. In her carreer she was the head of the Petrological, Mineral Deposits Departments, the Group of Rocks and Mineral Collections, the Centre of Excellence and the National Geological Archives in PGI-NRI, Poland. She has been co-ordinating many projects. She is an author of over 120 papers, a reviewer and an editor. She has an experience in fields of isotope studies, fluid inclusions and hydrocarbon migration in different environments, as the Carpathians, in the marine deposits from the Baltic Sea, other hydrocarbon-bearing regions as well.
Abstract:
As it has been postulated by Oliver (1986), when continental margins in zones of convergence are buried beneath thrust sheets, fluids expelled from the margin sediments go to the foreland basin and the continental interior. These fluids play key role in different phenomena, as e.g., faulting, migration of hydrocarbons, and mineral transportation. The North American case is a very good example of this hypothesis, relating both oil and gas fields and their occurrences as well as e.g., lead-zinc deposits to the tectonic belts there (as the Appalachians). In Europe, the Carpathian Mountains chain is a fragment of the orogenic belt that cuts a large part of the continent. Oil and gas fields are present in the Carpathians and the Carpathian Foreland, as well as hydrocarbons are accessible at the microscopic scale – in fluid inclusions in minerals in the rocks. Hydrocarbons are very common and widespread in sedimentary rocks in the different Carpathian units and point to mobility and circulation of fluids. Such an evidence has been already mentioned in general by Roedder (1984), and it is proved by recent publications concerning brine and hydrocarbon inclusions in the distinct zones at the Polish-Ukrainian boundary (Jankowski, JarmoÅ‚owicz-Szulc, 2011; JarmoÅ‚owicz-Szulc et al., 2012; JarmoÅ‚owicz-Szulc, Jankowski, 2013). The analysis has been conducted pointing to a presumed HC migration in two directions. The results are important in search for hydrocarbons.

Keynote: Ultrasonic technology for enhanced oil recovery. Viscosity reduction by ultrasonic treatment
Time : 10:35-11:05
Biography:
Vladimir Abramov has completed his PhD at the age of 26 years at the Moscow Institute of Steel and Alloys. He is a professor in technical sciences since 2007 and the head of the laboratory of ultrasonic technique and technology in his institute. He has published more than 150 papers and patents, is a member of the European society of sonochemistry and the World Assotiation for Ultrasound Applications. In 2008 he received the Russian Government Prize for achievements in the field of science and technology. He and his team has over 30 years of experience in the field of EOR.
Abstract:
The ultrasonic and sonochemical method of EOR is one of the most promising methods, since it can be applied for the treatment of wells, which has already been subject of EOR, horizontal wells and heavy oil wells. It was developed over 30 years ago, but only today the state of the technique enables us to deliver enough energy to the perforation zone to show significant results. The method is based on years of research and involves not only ultrasonic treatment of the perforation zone, but also preliminary analysis of the perforation zone, determination of treatment intervals for selective treatment and subsequent pump-out using a specially designed jet pump. Only in such a way the method can be economically sound, especially in case of horizontal wells.
The technology delivers an ultrasound frequency to the reservoir which has the impact of reducing skin damage, putting resins, asphaltenes and waxes back into solution, and increasing penetration into capillars resulting in enhanced production and recovery of oil. Average results are a doubling of production and in some cases up to over a 900% increase.
In case of heavy oil the effect of viscosity reduction, caused by ultrasound is particularry important, since it contributes not only the the increase of production, but also facilitates the transportation of oil. For such cases we have developed a sonochemical technique, which allows us to secure the viscosity reduction by adding chemicals afterwards.

Abstract:
The objective of this work is the investigation of production possibility of high octane environmental ethanol gasoline blends based on Euro specifications. The environmental gasoline is the key to keep the environment safe and clean. Moreover, it aids in reducing gas emissions after combustion of gasoline. One of the main methods to produce the environmental gasoline is blending gasoline with oxygenated compounds such as ethanol. Ethanol is chosen among other oxygenated compounds as it has a high influence on physico-chemical characteristics of gasoline rather than other oxygenated compounds. In addition, it has a high octane number as well as it is not polluting the environment and clean additive. In the experimental study, the choice of environmental gasolines is based on Euro-3 specifications for samples without ethanol blend and Euro-5 specifications for samples with ethanol blend; after upgrading. Various blend stocks have been prepared which have reformate, isomerate, full refinery naphtha (FRN), heavy straight run naphtha (HSRN), hydrocracked naphtha, heavy hydrocracked naphtha, coker naphtha and heavy coker naphtha. In this study, ASTM standard methods are performed for spark ignition fuels to characterize its physical and chemical properties. The results show that one has exhibited the optimum specifications of Euro-3 and thus its physico-chemical characteristics are 755.11 kg/m3 of density, 55.88 of oAPI, 95 of RON, 88 of MON, 40% by volume of aromatic content and 0.66% by volume of benzene content. Moreover, ASTM distillation curve shows that the volume percentage at 150oC is 83. At the same time, the final boiling point (FBP) and recovery volume percent are 198oC and 96 respectively. While another sample has the poorest physical as well as chemical properties so that it is blended with ethanol to upgrade its characteristics. Therefore, the target is determining the optimum ethanol volume percent to be blended with poorest sample to yield the highest properties of gasoline. These blends are namely as E0, E5, E10, E15, E 20. The results indicate that E5 is the optimum one for Euro-5 specifications after upgrading and thus its physico-chemical characteristics are 745.55 kg/m3 of density, 58 of oAPI, 101 of RON, 98 of MON, 32.65% by volume of aromatic content and 0.47% by volume of benzene content. Moreover, ASTM distillation curve illustrates that the volume percentage at 150oC is 75. At the same time, the final boiling point (FBP) and recovery volume percent are 190oC and 97 respectively. In addition, its Reid vapor pressure equals 8.1 psi and the heat of combustion equals 35 MJ/L. In the final, Blending gasoline with ethanol is an essential issue concerning the production of environmental gasolines.

Title: Characters of reservior and Main Control Factors in Upper Second Member of Shahejie Formation(Es2) in Linnan Sub-sag
Biography:
Feng Yuelin is a PhD candidate from China University of Petroleum (East China), studying in the area of petroleum geology.
Abstract:
The Shuangfeng area is located in the Linnan Sub-sag, Huimin Depression, Bohai Bay Basin, China. This area contains four oil-bearing series: lower Es3, middle Es3, upper Es3 and Es2. However, the reservoirs in Es3 formation are low permeability, resulting high cost exploitation. Reservoirs in upper formation (Es2) become focused. Depending on the braided delta facies in Es2, the reservoirs can be divided into three types: Distributary channel reservoir, under water distributors channel reservoir and mouth bar reservoir. On the basis of core observing from 28 wells and 62 samples, a regional study, involving thin section, scanning electron microscopy and mercury injection method, has been undertaken. The thin section results indicate that the clastic rocks of distributary channel reservoir are mainly lithic arkose and lithic sandstone. The major lithology of underwater distributary channel reservoir and mouth bar reservoir are feldspathic litharenite sandstone. All of them have good sorting and middle texture maturity. The scanning eletron microscopy result shows that there exist two types: macroporisity and microporosity. The mercury injection method figures up the physical property of the three reservoirs. The calculation of compacted rate shows that the three type reservoirs have the similar range. All the analysis show that:1) the main principal controlling factors in reservoir are sedimentation, the diagenesis and lithology have less influence; 2) in Shuangfeng area the mouth bar reservoir has better physical property than the other two types. The results make the controlling factors of reservoirs clear and will help the oil and gas exploration in the region.

Title: Characters Of Sedimentary Facies And Main Control Factors In Upper Fourth Member Of Shahejie Formation In Qingnan Sub-sag
Biography:
Zhang Tianjiao is a PhD student from China University of Petroleum, East China, studying in the area of petroleum geology.
Abstract:
The Qingnan sub-sag is located within the Dongying Sag, Jiyang Depression, Bohai Bay Basin, on-shore China. This sub-sag was indicated as a promising exploration area, however, compared to the other sub-sags in the Dongying Sag, the characters and distribution characteristics of Qingnan sub-sag remain poorly understood which restricts the oil and gas exploration in this region. A regional study, involving core observation, well-logging, 3-D seismic, sporopollen, organic carbon content, characteristic elements and heavy mineral, has been undertaken. The fan delta, delta and beach bar were recognized based on 20 core observation and well-logging data. The paleogeomorphic shows stable shallow semi-enclosed sub-sag based on the 3-D seismic data covering the region, making the paleo-hydrodynamic power weak. The paleo-climate is humid and hot which is indentified by sporopollen fossil, including pinaceae, granodiscus and quercoidites. Two provenance systems were recognized based on the characteristic elements and heavy mineral. All the analysis show that: 1) the gentle paleogeomorphic is advantage of the development of fan delta, delta and beach bar; 2) the humid and hot paleo-climate provides accommodation space and protection for the clastic sedimentary of fan delta and delta; 3) the fan delta is controlled by the north provenance system, the delta is controlled by the south provenance system, beach bar is controlled by the both; 4) the weak power of paleo-hydrodynamic restrict the distribution range of beach bar.The results make the distribution regularity of sedimentary facies clear and will help the oil and gas exploration in the region.

Title: Novel Mesoporous Silicas for Oil Adsorption from Produced Water Injected in Oilfield using Fixed Bed Column Processes
Biography:
Rasha Hosny Abd Elmawla has completed her PhD at the age of 32 years from Benha University and still postdoctoral studies at Egyptian Petroleum Research Institute (EPRI).
Abstract:
In this paper we prepared mesoporous silica by simple single step method to separate oil (and gas) from produced water. Investigate the prepared mesoporous silica by XRD, FTIR, Raman, N2 adsorption–desorption and TEM. Then a continuous fixed bed study was carried out using prepared mesoporous silica for oil removal from produced water. The effects of flow rate and bed height on the breakthrough characteristics of the adsorption system were determined. XRD analysis of the silica powder showed complete formation single phase mesoporous without contamination of other phases of silica. The maximum removal (70.26%) was achieved for a flow rate of 0.5mL/min and a bed height of 1.5 mm. Two models Thomas and Yoon–Nelson were applied to predict the breakthrough curves. The results show that Thomas model was fitted well the adsorption data with a correlation coefficient (R2) at different conditions. R2 values suggested that the suitable model for describing the chemisorption oil on prepared mesoporous silica was Thomas model. The model showed that the prepared mesoporous silica was suitable adsorbent for oil using fixed bed adsorption.

Title: Relative Permeability Prediction Considering Complex Pore Geometry and Wetting Characteristics in Carbonate Reservoirs
Biography:
Sun-lee Han received her BS from Chonbuk National University. She is MS student in Petroleum Engineering Lab. of Chonbuk National University. She is studying about fluid flow in complex pore network, CO2 EOR and reservoir simulation
Abstract:
The measurement of kr (relative permeability) in carbonate rock is difficult and has great uncertainties due to the complex pore system such as dissolved pore, cavity and fractures. Several equations for the calculation of kr are developed, but they assume single pore system that it cannot be applied directly to the complex pore system. Furthermore, the wetting characteristics have to be considered because most carbonate rocks tend to oil-wet. This study presents the method of kr estimation with respect to the heterogeneous pore network. Firstly, the wetting characteristics are determined by the measurement of contact angle. For each core, pore size distribution, Pc (capillary pressure) and residual oil saturation are measured. From the estimated contact angle, all the samples are determined as an oil-wet. It is observed that Pc has different curve according to the macro and micro-pore, respectively. Then, kr is generated from Pc by using Brook-Corey equation for each pore size. As a result, for the macro-pore, the water has higher kr than oil that it can be displaced easily by only the small reduction of oil saturation. In contract, the micro-pore has general shape of kr curve. Consequently, it is found that oil flows differently through macro and micro-pore according to the oil saturation

Title: An experimental study of sorption characterisrics for the sub-bituminous coal considering size effect
Biography:
Donghyeon Kim received his BS from Chonbuk National University. Currently, he is MS student in Petroleum Engineering Lab. His experiment topic is sorption characteristic of various coal size by methane gas.
Abstract:
In this study, adsorption and desorption characteristic were analyzed by changing the particle size of coal in order to estimate the CBM production potential. We used sub-bituminous coal samples from Kotabaru filed in Indonesia and volatile matter, ash and moisture content analyzed. All samples were crushed and they are divided into seven groups with particle size from 50mesh to 20 mm. For each sample, volumetric method was applied to measure the Langmuir pressure (PL), Langmuir volume (VL), and equilibrium time. From results, as particle size increases, Langmuir volume that is the maximum gas content of the sample decreases due to the reduction of specific surface area, but they show a little difference. In contrast, in desorption process, more time was needed for the large particle size to reach an equilibrium state because desorbed gas flow through the longer path and defuses by the concentration difference. In conclusion, desorption characteristics with coal size should be considered because the pore volume, pore size, and effective surface area are different. Moreover, Langmuir isotherm measurement for the lump coal considering cleat spacing is essential to obtain a more precise CBM production profile.

Title: Storage Permeability Body Classification in Low Permeability Water Bearing Gas Reservoir- a Case study of Gaoqiao Gas Field, Ordos Basin, China
Biography:
Yan Haijun received his BS degree in Petroleum Engineering from the Northeast Petroleum University and his MS degrees from Research Institute of Petroleum Exploration & Development (RIPED), Beijing, China. From 2006, he has worked in the areas of oil & gas geology, gas development. He is currently the Engineer in the Department of Ordos E&P, RIPED, working mainly on gas development. As an Engineer, he has published over 10 papers and 1 book.
Abstract:
At present, a large number of low permeability water bearing gas reservoirs have been found in the world, and meanwhile, there are more than 2×104m3 reserves distributed in this type reservoir in Sichuan and Ordos basin, China.This kind of gas reservoir is characterized by poor reservoir physical properties, strong heterogeneity, high water saturation, complex gas and water distribution, and no obvious gas-water contact. The primary problem to develop this type reservoir is how to optimize the building area. Because of the complex formation water distribution, the application effect of conventional optimize method is not good. Any reservoir is characterized by two aspects of storage and permeability. In this paper, according to the physical property and movable water, the reservoir is divided into six storage permeability bodies by using dynamic and static data. Gaoqiao gas reservoir is located in the Ordos basin, and belongs to the low permeability water bearing gas reservoir. Take the Gaoqiao as an example, the classification criteria of storage permeability bodies are established and the type of drilled wells is classified. Based on the understanding of gas reservoir characteristics, the plane distribution of storage permeability body is drawn. Based on this distribution, we can optimize the development area in Gaoqiao. This method can be used to optimize the development area to develop such reserves. Furthermore, this method is helpful for the effective development of a large number of these gas reservoirs in China and the world.

Title: : Development and operation practice on miniature liquefiers for scattered and isolated natural gas resources
Biography:
Maoqiong Gong has completed his PhD at Chinese Academy of Sciences. He has published more than 200 papers in reputed journals and has been serving as an Editorial Board Member of repute.
Abstract:
A series of moveable small scale skid-mounted liquefiers for scattered and isolated natural gas resources have been developed and tested, with liquefaction capacity of 10,000 Nm3/d, 15,000 Nm3/d, 30,000 Nm3/d, 60,000 Nm3/d and 100,000 Nm3/d. The compressor unit and cold box of liquefiers are compactly integrated in a skid. The liquefiers are based on a mixed-refrigerant liquefaction cycle with R22 pre-cooling. Most of the devices in liquefiers are easily available commercial refrigeration products. An oil-lubricated single-stage screw compressor is used for the compression of mixed-refrigerant, combined with air coolers. The core of cold box is an aluminum plate-fin heat exchanger with four flow passages. The liquefiers were tested and operated under different conditions. The minimum specific power consumption of 10,000 Nm3/d type was 0.54 kW h/Nm3, which was equivalent to 15.3% of the gas consumed with the rest liquefied. The power consumption of 30,000 Nm3/d type and 100,000 Nm3/d type were only 0.40 kW h/Nm3 (including all facilities) and 0.35 kW h/Nm3 respectively. This series of liquefiers could cover various liquefaction requirements such as small natural gas or coal-bed methane exploitations, distributed peak-shaving, and boil-off gas reliquefaction. A flexible distributed liquefaction center could be established with the combination of a set of small liquefiers.
