  • Simplification of complex fracture morphology and its impact on production
    • Authors: Palash Panja, Jing Zhou, Milind Deo
      Pages: 143 - 168
      Abstract: Significant amounts of oil and natural gas in the USA are produced from fractured reservoirs. Fracture morphology and effectiveness of fracturing job depend on various factors such as geological properties (permeability, porosity, and heterogeneity), mechanical properties (Young's modulus, Poisson's ratio, stress anisotropy, maximum horizontal stress) and fracturing operational parameters (fluid injection rate, fluid viscosity). Reservoir engineer's job is to import the fracture geometry into reservoir flow simulator in order to forecast the production of hydrocarbons to evaluate a play's potential. In this research, various issues related to simplification of rigorously-generated fractures are investigated. A systematic approach including practical flow consideration in hydraulic fracture with heterogeneous permeability and width along the length is developed. The complex fractures morphology is simplified in two proposed models with mathematical formulations. Simplified models show promising alternatives in rapid forecasting of production of hydrocarbon without losing the characteristic of fracture properties like complex morphology and bottleneck. Oil recovery, cumulative gas oil ratio (GOR), oil rate and average reservoir pressure are compared with results from complex fracture morphology. One field case is used to demonstrate the validity of the method. [Received: May 9, 2017; Accepted: March 23, 2018]

  • Kinetics features of natural gas hydrates crystallisation and dissociation
           in water/crude oil and water/asphaltene-resin-paraffin deposit emulsions
    • Authors: Vladilina V. Koryakina, Izabella K. Ivanova, Matvey E. Semenov
      Pages: 169 - 185
      Abstract: The crystallisation and dissociation of natural gas hydrates synthesised in paraffin oil emulsions of the Irelyakh deposit (Eastern Siberia) and in emulsions of asphaltene-resin-paraffin deposits (ARPDs) originated from this oil have been studied with application of high-pressure differential scanning calorimetry (HP DSC). Crystallisation of hydrate-containing phase in the water-in-ARPD (W/ARPD) emulsions with formation of natural gas hydrates enriched with methane and ethane has been defined to proceed much slower than the rate of formation and composition of hydrates formed in water-in-oil (W/O) emulsions. The hydrates grow better in emulsified water droplets than in bulk water, while the hydrate content decreases with increase of water cut in W/O emulsion, and a slower rate of hydrate formation in the W/ARPD emulsion, as compared with W/O emulsion, leads to a greater conversion of water droplets into hydrate phase. It has been shown that more stable hydrates are formed in W/ARPD. [Received: September 9, 2017; Accepted: February 13, 2018]

  • Aromatisation and desulphurisation of liquefied petroleum gas over
           Zn-containing zeolite catalysts modified by transition metals
    • Authors: Tuktin Balga Tuktievich, Shapovalova Larissa Borisovna, Nurgaliyev Nurzhan Nurlybekovich, Tenizbayeva Aliya Serikovna, Bagasharova Bates Muhtarovna
      Pages: 186 - 198
      Abstract: In this paper, treatment of liquefied petroleum gas (LPG) over Zn-containing zeolite catalysts modified by Mn, Cu and Fe was studied. The authors investigated catalytic activity in the aromatisation and desulphurisation reactions of propane-propylene and propane-butane fractions (PPF and PBF respectively). It was found that the feedstock composition did not actually affect conversion at elevated temperatures (550–600°C); however, yield of the resulting aromatic hydrocarbons was higher when using PPF. The activity of catalysts mainly depended on the structure and state of active sites and reaction conditions. During PPF desulphurisation, the Zn-Mn-ZSM-Al<SUB align="right">2O<SUB align="right">3 catalyst was the most active, while the Zn-Fe-ZSM-Al<SUB align="right">2O<SUB align="right">3 catalyst showed the highest activity with the PBF. Physical and chemical characteristics of the obtained catalysts were studied using various methods. [Received: September 20, 2017; Accepted: March 16, 2018]

  • Underground coal gasification techniques for different geo-mining
           conditions
    • Authors: Ranjeet Mandal, Raj Kumar, Md. Shahnawaz Ansari, Dinesh Kumar, Swades Kumar Chaulya, Girendra Mohan Prasad, Ajay Kumar Singh, Tanmoy Maity
      Pages: 199 - 217
      Abstract: Underground coal gasification (UCG) technique provides facilities for converting underground coal into synthetic gas by remote ignition and injecting steam as well as air into the coal seam. This product, which is also known as syngas, is a mixture of combustible gases like carbon monoxide, hydrogen and methane; and non-combustible gases like carbon dioxide, nitrogen and water vapour. This syngas is utilised for generation of emission-free power, ultra-clean diesel and manufacture of ammonia, fertiliser and other various valuable chemical products. The UCG technique is not only cost-effective but also environment friendly. This technique can also be employed for recovering coal from areas where conventional mining is either difficult or uneconomical. Due to this remarkable feature, UCG technique is going to play a greater role in coming years with the depletion of easy exploitable coal day by day.

           pre-treated Indian coals

      Abstract: This work focuses on the interaction of coal with three different ionic liquids (ILs) and mixed solvent for analysing the oxidising effect on Indian coal. The ILs; 1-butyl-1-methylpyrrolidinium methyl carbonate [BMPYR][CH<SUB align="right">3CO<SUB align="right">3], 1 butyl-3-methylimidazolium hexafluorophosphate [BMIM][PF<SUB align="right">6], and 1-butyl-4-methylpyridinium tetrafluoroborate [BMPY][BF<SUB align="right">4] were subsequently used for dissolution studies. The thermogravimetric analysis result shows that the mass loss was less for [BMPYR] [CH<SUB align="right">3CO<SUB align="right">3] and mixed solvent ([BMPYR][CH<SUB align="right">3CO<SUB align="right">3] + pyridine) pre-treated coal as compared to other. Hence the IL has the largest ability to fractionate the more active oxygen containing functional groups present in the coal. The thermal degradation study shows that the thermal stability of mixed solvent and IL-pre-treated coal provides a temperature of above ~630°C, which is a quite high as compared to raw coal. The IL-pre-treated coal also requires lesser energy (low activation energy) during gasification processes which will be beneficial from an economic point of view.

  • Extraction of phenols from coal tar oil using binary solvents and ionic
           liquid mixture
    • Authors: Subhash Kalidindi, S. Abhishek Vinayak, Shoumitra Biswas, Duraisamy Kumaresan, R. Krishna Prasad
      Pages: 240 - 260
      Abstract: The extraction of phenols from coal tar oils using acetonitrile solutions of ionic liquids (ILs) through a new extraction method is studied. The IL containing acetonitrile solution formed a clear immiscible layer with hexane containing coal tar oil, which facilitated superior extractions of phenol and p-cresol with high distribution coefficient values. The IL with lower carbon chain length (three carbons) showed extraction efficiency greater than 96% for phenol and p-cresol extractions from coal tar oil. The process models for extraction of phenol and p-cresol from coal tar oil were studied to comprehend the interactions of various factors. [Received: December 23, 2017; Accepted: March 7, 2018]

  • Selection of optimum bio-diesel fuel blend using fuzzy TOPSIS and
           fuzzy VIKOR approaches
    • Authors: C.M. Sivaraja, G. Sakthivel, R. Jegadeeshwaran
      Pages: 261 - 291
      Abstract: The ever increasing demand and depletion of fossil fuels along with environmental concern has prompted search for alternate fuels. The selection of optimum biodiesel with the appropriate blend for the IC engine plays a vital role in the energy sector. This paper describes the application of novel hybrid multi-criteria decision making (MCDM) technique to evaluate the optimum fish oil biodiesel blend. Fuzzy TOPSIS and fuzzy VIKOR are used to evaluate the best blend, where fuzzy is to determine the relative weights of the criteria, TOPSIS and VIKOR has been used for obtaining the final ranking of alternatives. A four stroke single cylinder, constant speed, direct injection with a rated output of 4.4 kW was used for exploratory analysis. The ranking performance of both the methods is also compared with each other and selected B40 is the best blend to operate the engine. The proposed MCDM models are simple, precise and efficient tool for the decision makers to identify the suitable blend among the alternatives. [Received: March 4, 2017; Accepted: March 7, 2018]
