  • Teaching Interests

    My teaching interest includes mathematical and numerical modelling of fluid flow in reservoir rocks, inverse modelling and optimisation, geostatistics and production engineering. I currently teach the following courses: 

    1. Reservoir Simulation, (third year level subject): The course gives the theoretical basis and practical fundamentals for mathematical modelling and numerical simulation of fluid flow in petroleum reservoirs. The governing laws and equations required for the modelling of single-phase and multi-phase flow in porous media, such as mass conservation, Darcy, equation of state, rock compressibility, capillary pressure and relative permeability, are reviewed. By combining these laws and equations, the corresponding partial differential equations are derived. The numerical methods for solving the governing partial differential equations using finite difference methods are presented.

    2. Reservoir Characterisation and Modelling, (third year level subject): The course has three main components. 1) Data sources, quality and analysis, including spatial analysis. 2) Generating 3D models of reservoir properties - classical gridding and mapping, kriging as a data-driven (variogram) form of classical mapping (estimation) and a means of data integration. Simulation techniques are introduced as a means of assessing uncertainty resulting from heterogeneity. 3) Scaling of grids and property models for the purpose of reservoir simulation is the final topic.

    3. Introduction to Petroleum Engineering (Production Engineering Part), (first year level subject): The aim of the course is to provide students with a broad overview of introduction to petroleum engineering in order that advanced courses in subsequent years can be understood within a broader petroleum engineering context. 

  • Research Interests

    My main field of research is Applied and Computational Mathematics targeting Reservoir & Production Engineering problems. That includes 

    • Computer-assisted algorithms for history matching 
      History matching is a nonlinear and computationally intensive inverse problem in which it is sought to tune (calibrate) the coefficients, initial and/or boundary conditions of nonlinear PDEs corresponding to multi-phase flow in porous media, based on observed data.

    • Techniques for uncertainty quantification
      The propagation of uncertainty in the parameters of interest (e.g., reservoir performance forecasts) can be obtained by drawing samples from a nonlinear and high-dimensional posterior probability density function (in a Bayesian framework).

    • Robust optimisation algorithms for field development planning and reservoir flooding improvement under geological uncertainties
      This is a numerical optimisation exercise with a highly nonlinear and uncertain (noisy) objective (fitness) function. Each function evaluation needs multiple execution of computationally expensive reservoir simulation.  

    • Surrogate (proxy) modelling techniques for reducing computational costs
      Reservoir production optimisation problems are computationally intensive, due to the nature of PDEs solved numerically for production forecasting. The computational costs associated with optimisation and calibration problems can be reduced by applying properly an approximation functions in the workflow. 
    • Linear and nonlinear Algebraic transformation methods for dimensionality reduction 
      A dimensionality reduction technique can improve the calibration problems, given the fact that the data are correlated to some extent and finding a basis that spans the search space will improve the process.

    • Modelling of unconventional resources (such as CBM and tight-sand reservoirs), CO2 sequestration and uncharacteristic phenomena in conventional reservoirs
      In order to simulate reservoir performance in some cases, e.g., unconventional plays, sometimes, it is required to tweak the existing tools or solve numerically a new set of governing PDEs that replicates the phenomenon.  

    • Data Analytics (DA) for fast decision making
      DA is gaining popularity in Oil & Gas industry in the recent years, due to the massive information gathered everyday with less time to analyse. DA can be an alternative to the physical-based simulators for making fast decisions.
