  • Foamed Cement Formulation with Particular Characteristics for Oil and Gas Well Cementing Jobs: An Experimental Approach, Ameri, H., Shadizadeh, S.R., Moghadasi, J., CEMENT AND CONCRETE COMPOSITES, under review.

Scientific Fields: Drilling Engineering, Oil and Gas Wells Cement Formulation, Drilling Fluids, Well Cementing Operation

Abstract: Ultra-lightweight cement is needed for fractured reservoir formations to prevent formation damages. One of the latest technologies for ultra-lightweight cementing jobs is foamed cementing.  In this paper, new foamed cement has been formulated and designed for Iranian liner and casing cementing jobs. The foamed cements are prepared at high shear rates by HA as a foaming agent. Different tests such as density, rheology, free water-settling, thickening time, compressive strength, fluid loss, porosity, permeability, microscopic photography and CT scan image are conducted for each of cement samples. The results show that the designed foamed cement (FBJ) has one of the lowest densities (75pcf), compressive strength of 1300 psi, thickening time near 3 hours. The porous media of FBJ’s set-cement are not interconnected and this is proved by porosity, permeability, microscopic photography and CT scan tests. FBJ has acceptable properties for oil and gas well cementing jobs.

  • Numerical Modeling of Coal Pillars in Inclined Layers, Field Study of Hamkar Coal Mine, Motahari, M., Ameri, H., GEOMECHANICS AND GEOENGINEERING AN INTERNATIONAL JOURNAL, under review.

Scientific Fields: Rock Mechanics, Drilling Operations and Extractions in Mines

Abstract: One of the most important sections of underground mining operations is pillar designing. One of the best modern methods for pillar designing is the numerical method, which is implemented in this paper by FLAC2D software. The advantages of this modeling programming to old pillar designing methods are that the parameters such as confining pressure, layer sequences and rooms extraction steps can be considered easily. In inclined layers, the pillar is affected by vertical and shear stresses significantly. At current work, the stresses distribution and displacement contours on pillars between two stopes are investigated by FLAC2D. The results of numerical modeling analysis on 30, 45 and 60 degrees layer inclinations with 10 and 15m pillar widths, illustrate that by increasing the layer inclination, the applied vertical and shear stresses magnitudes to the pillar are reduced. Moreover, the displacements at the top of the stopes and pillars are increased and the maximum displacement region becomes wider according to increase the layer inclination. Finally, it can be concluded that in an inclined layer with a greater angle, the pillar with a larger dimension must be used in this case study.

EAGE CONFERENCE PAPERS

  • The Rock Mechanical Properties Evaluation for LI Region of an Oil Field in Southwest of Iran, Ameri, H., Motahari, M., 81st EAGE Annual Conference and Exhibition, Oral Presentation, London, UK, Jun. 03- 06, 2019, DOI: 10.3997/2214-4609.201900941.

Scientific Fields: Rock Mechanics, Wellbore Stability

Abstract: Rock mechanical properties are essential data for wellbore stability analysis and in-situ stresses profile prediction for a well and a field. These properties are unknown in LI region of Gachsaran oil field in the southwest of Iran as a result of the lack of comprehensive investigation in this area. Some petrophysical logs (Dipole Sonic, Density, Neutron, and Gamma-ray log) data are utilized for relations computation. Different empirical relations are used to calculate LI region rock mechanical properties such as static Young’s modulus, Poisson’s ratio, uniaxial compressive strength (UCS), cohesion, internal friction angle, shear modulus, and bulk modulus. All of these data could be used for diverse wellbore stability studies. In addition, the experimental triaxial tests are applied to five various specimens that are gained from different depths of a well. The comparison between the test data and the results of empirical correlations clears that which equation is more appropriate for LI region rock mechanical properties estimation. Moreover, the range of each property magnitude is determined for future research and works to approach the safe and economical drilling operations and wellbore stability analysis.

  • Investigation of Pillar Width Effect on Pillar Stability in Inclined Layers by Numerical Model, Hamkar Mine Field Study, Ameri, H., Motahari, M., 80th EAGE Annual Conference and Exhibition, Electronic Poster Presentation, Copenhagen, Denmark, Jun. 11- 14, 2018, DOI: 10.3997/2214-4609.201801684.

Scientific Fields: Rock Mechanics, Drilling Operations and Extractions in Mines

Abstract: One of the most important sections of mining operations is pillar designing. If this designing will be done well, finally the mining plan will be safe and so much economical. One of the best modern methods for pillar modeling and designing is the numerical method, which is done at this paper by FLAC2D software. The advantages of this modeling programming to old pillar designing methods are that the parameters such as confining pressure, layer sequences and rooms extraction steps can be considered easily. There are a lot of differences between designing a pillar in inclined layers and in normal horizontal layers. In inclined layers, the pillar is affected by vertical and shear stresses significantly. Two basic numerical models are made at this project. For better analyzing of pillar width effect on its stability in inclined layers, two pillars with 10 and 15 meters width, at constant 30 degrees layer inclination and with two stopes with 90 meters length, are modeled. This study is on the coal layers of Hamkar coal mine in Iran, 50 kilometers far from Ravar city in the northwest of Kerman province. Therefore, with this modeling and analysis, the effect of pillar width on its stability is recognized. One of the results of this numerical model is that with increasing the pillar width, the vertical stresses, which are applied to the coal pillar, are decreased. Similarity, at most points of the coal pillar, applied shear stresses decreasing by increasing in the pillar width. It can be recognized that with increasing the pillar dimensions, the instability of the pillar is reduced at a constant layer inclination degree. Finally, it can be concluded that at the specified constant layer inclination, the pillar width must have an optimum magnitude to not be damaged due to vertical and shear stresses. Otherwise, pillar reinforcement should be considered in the mining planning and this not been made an economical plan. Therefore, just the pillar with 15 meters width is safe in 30 degrees layer inclination and it can be used as a plan for Hamkar coal minefield.

  • The Comprehensive Analysis of Porous Structure of Foamed Cements by CT Scan, Ameri, H., Shadizadeh, S.R., Moghadasi, J., The 16th Iranian National Congress of Chemical Engineering, Jan. 19- 21, 2019, Iran, Conference ISC Code: 97180-91706. (in Persian)

Scientific Fields: Drilling Engineering, Oil and Gas Wells Cements, Drilling Fluids, Foamed Cements Structure

Abstract: Foamed cement technology application is one of the innovations in oil and gas wells drilling operations. In this paper, the porous media and pores distribution in the foamed cement plugs have been investigated by computed tomography scanning (CT Scan) and three-dimensional image-processing rendering. Also, by different permeability and porosity tests, the pore distribution has been predicted. By comprehensive analysis, FBJ as designed drilling foamed cement formulated by mixing of an acid, a sodium lignosulphonate retarder, and a foaming agent, has one of the highest porosities and lowest permeabilities. These results have been proved by microscopic photography and CT scan. On the other hand, other foamed cements may have high porosity but do not have low permeability and vice versa. These types of foamed cement are not applicable for a real operation in the oil and gas wells cementing. The best foamed cement is that one with the highest porosity and lowest permeability.

  • Experimental Investigation of Different Retarders Effects on Foamed Cements Rheology, Ameri, H., Shadizadeh, S.R., Moghadasi, J., The 5th National Conference on New Research in Chemistry and Chemical Engineering, Jan. 31, 2019, Iran, Conference ISC Code: 97180-72102 (in Persian)

Scientific Fields: Oil and Gas Wells Cements, Drilling Engineering, Fluids Mechanics 

Abstract: The drilling new production wells in depleted or highly fractured reservoirs are accompanied by several damages, risks and not predicted problems. The high percentage of these damages that are applied to the reservoirs and formations occur during the cementing operation in the oil and gas wells. Most of the time, the compensating of these formation damages is very difficult and may inapplicable. In these situations, one of the methods of formation damage prevention and reduction is the application of lightweight and ultralightweight cements such as foamed cements. Generally, the thickening time of foamed cements are short and as a result, some retarders are added to them for retarding the thickening time of slurry. Although, depending on the foaming agent and retarder properties, the rheology of each slurry is varied in the slurry mixture. By conducted experiments in this project, OR5 and OR12 as Calcium lignosulphonate retarders, made worse rheology in both surface and high-pressure high-temperature (HPHT) conditions by increasing the Plastic Viscosity (PV) and Yield Point (YP) of each foamed slurry. JR120 as a Sodium lignosulphonate affects very well in the surface condition although, in HPHT condition, it loses its efficiency. In the current work, the best rheology properties have been reached by combining and mixing the JR120 and Boric Acid and a foaming agent amongst all conventional and foamed cements in surface and HPHT conditions.

  • The Study of Managed Pressure Drilling (MPD) Technology Application at Oil and Gas Wells Drilling Operations, Ameri, H., National Congress on New Research Ideas in Engineering Science, Technology, Electrical and Computer Science, May. 09, 2018, Iran, Conference ISC Code: 97180-12703 (in Persian)

Scientific Fields: Drilling Engineering, High-Tech Operations in Engineering

Abstract: The drilling operation is one of the most important sections of oil and gas fields development and petroleum engineering. There are different drilling operations methods and one of them is managed pressure drilling. For a safe drilling operation, it needs to fluid column hydraulic pressure in the well be between pore and formation fracture pressures.  Usually, drilling operations are done by pressures that are more or less than the pore pressure, thus the new technology of drilling with lowest formation damages and secondary expenditure is the best operation. This new technology is managed pressure drilling (MPD). In the oil and gas wells cementing industry, managed pressure cementing (MPC) is used by the reason of MPD in drilling. These technologies have a high initial cost, however, in a long period are economical with high efficiency. In Iran, because of the old age of reservoirs and their pressure depletion, these technologies are very useful for formation damage reduction and higher hydrocarbon recovery in a long time. In this paper, the possibility of conducting MPD and MPC in the Iranian oil and gas wells has been studied and the candidates for these operations have been suggested.

  • The Comprehensive Investigation of Microbial Enhanced Oil Recovery (MEOR) Operation and Its Efficiency, Ameri, H., 2nd National Conference on Modern Advances in Energy Sector and Oil and Gas Industries, May. 04- 05, 2018, Iran,  Conference ISC Code: 96170-61308 (in Persian)

Scientific Fields: Enhanced Oil Recovery (EOR), Innovations in Engineering, Reservoir Engineering

Abstract: Today, oil and gas production are decreased due to reservoirs depletion in all around the world. Thus, in most countries, secondary and tertiary recovery methods are used widely to increase production. Enhanced Oil Recovery (EOR) has several types with different efficiency. One of the innovations in EOR operation is the usage of biology and biochemistry science. It means that by injection of microorganisms to the well or reservoir, the high weight components of a heavy crude oil such as NSOs and C7+ are disintegrated and decomposed to lighter components with lower viscosity. As a result, the lighter crude oil can flow easier in the porous media and tubing string and the volume of asphaltene deposition is reduced. In this paper, the comprehensive investigation and analysis have been done for Microbial Enhanced Oil Recovery (MEOR) efficiency and its advantages and disadvantages. According to these studies, MEOR is conducted rarely in real field operations and most of its results have been analyzed in the laboratory scales. The microorganisms’ functions in the HPHT condition in the real reservoir (not modeled) are usually uncontrollable. Thus, the MEOR has a high risk in operations if not controlled due to the uncontrollable bacterial proliferation that may cause the production reduction itself.

Scientific Fields: High-Tech Engineering, Well Completion, Production Enhancement, Automation and Instrumentation

Abstract: Todays by increasing oil and gas productions, situation selection of hydrocarbons optimized production became very important. In all around the world, reservoir productions are done by different mechanisms. These mechanisms and methods are chosen with attention to the type of reservoir and economic issues. By developing automation and instrumentation sciences, this knowledge is used in the oil industry and its wells. Therefore, one of the most important innovations in the design and operation of wells in oil engineering is the intelligent wells, which are intelligently and automated with a series of sensors and in-well equipment, wells behavior such as flow, pressure, temperature, production fluids type, etc. are controllable. In this paper, introducing some advantages of smart wells than conventional wells are tried. Hence, can be concluded that these wells are so much accurate and controllable than conventional wells and they reduce the risk of drilling and producing operations. Therefore, either smart wells do not have the problems of conventional wells, or it makes some benefits and optimization factors for wells maintenance and reservoir management for petroleum engineers.

  • Carbon Dioxide Pollution Reduction by CO2 Sequestration Technology in Depleted Oil and Gas Reservoirs, Ameri, H., National Conference of New Researches in Agricultural Engineering, Environment and Natural Resources, Mar. 04- 05, 2018, Iran, Conference ISC Code: 96170-72403 (in Persian)

Scientific Fields: Pollution Reduction, CO2 Sequestration, Reservoir Engineering

Abstract: One of the main gases that cause air pollution is carbon dioxide. The important sources of CO2 releasing are factories and power plants (sites). Abandoned and depleted oil and gas reservoirs as a porous media with un permeable caprocks are the best underground structure candidates for CO2 storage. In these operations. the old oil and gas production wells are transformed into CO2 injection wells. In this project, the appropriate condition for safe and economic and highly efficient sequestration has been studied. Note that the gas injection pressure must be in a suitable range to avoid formation/caprock fracturing. Moreover, the CO2 storage must not be applied in the aquifer of reservoirs to reduce the acidity of reservoir fluid. If a CO2 sequestration job simulated accurately with precise calculations, this operation can assist the air pollution reduction in some industrial cities and help the health of humanity. This research would be applied in different Iranian CO2 ­storage operations such as the Qom Salt Dam reservoir project.

Scientific Fields: Pollution Reduction, Automation and Instrumentation, Process Optimization

Abstract: One of the most polluting industries in the world is the petroleum industry. This industry is very widespread in the south and southwest of Iran. Therefore, the amount of pollution in these regions is very high. Various types of pollution caused by the oil industry. However, the most important type of them is air pollution. In the current project, the best modern methods for air pollution decreasing in Iran have been recommended. For air pollution reduction can use the instrumentation and automation science to control the pollution and polluting fluids concentration in any flow path by different smart soft sensors. Another recommended method for decreasing air pollution is biofilter usage that can adsorb some types of pollutions. Also, gas refining with the highest efficiency is one of the best procedures to reduce air pollution in Iran. By vast research and analysis, the best methods amongst three suggested procedures in this paper, soft sensors application has the highest efficiency and pollution reduction in oil/gas flow paths.

Scientific Fields: Drilling Fluids, Lightweight Drilling Muds, Drilling Engineering

Abstract: There are several issues and problems during a drilling operation in depleted or low-pressure hydrocarbon reservoirs. Fluid loss and pipe sticking and other hard situations occur during drilling jobs in these reservoirs. Uncontrollable drilling fluid losses in highly fractured reservoirs are inevitable and are accompanied by high costs. Moreover, the structural sequences of shales and sandstones in some formations cause the high risks of the drilling operation and this is the reason for remaining the undeveloped reservoirs. In recent years, a new particular drilling fluid has been introduced that eliminated the general challenges of drilling in depleted reservoirs and caused an obvious reduction of formation damage. Therefore, the productivity coefficient and recovery factor of reservoirs are clearly increased. The experiences of drilling jobs with this drilling mud present this fluid enhances the rate of penetration of each operation. In this article, this innovation in drilling fluids technology as Aphron muds has been introduced and its better functions and properties in the comparison of conventional muds have been investigated. Aphrons are the colloid based muds that the small gas bubbles are distributed in a viscous liquid that made of biopolymer and some surfactants.

Scientific Fields: Enhanced Oil Recovery (EOR), Fluids Mechanics, Reservoir Engineering

Abstract: One of the basic challenges in oil recovery is the production of heavy oil reservoirs. Recently, by the development of nano-technology, the new methods have been introduced to increase the recovery factor of these heavy oil reservoirs. Viscosity reduction is a common method in the enhanced oil recovery (EOR) operation in the heavy oil reservoirs. In this paper, the effects of hydrophilic-hydrophobic silicate nanoparticles on the viscosity of synthetic and crude oil have been investigated. The tested crude oil is an Iranian southwestern oil reservoirs fluid and the synthetic oil has been made by dissolving extracted asphaltene particles in the toluene. The nanoparticles have been added to the oil in the weight percent of 0.1 to 0.5 and the viscosity of the mixture was determined by a rotary viscometer. The results show that silicate nanoparticles increase the synthetic oil viscosity and reduce the crude oil viscosity. It must be noticed that this viscosity reduction is more for hydrophobic silicate nanoparticles than hydrophilic ones and the most reduction occurs in 0.2 weight percent of the nanoparticle.
