Extra Korolev producers: their impact on production

Yskak, Aidos
In this study, a three-dimensional, three-phase dynamic simulation model based on geological investigations of Korolev oilfield in Kazakhstan was used as a development planning tool in order to improve performance of three new wells. The model, developed previously by means of a seismic study, well log and core data, incorporating with characteristics of oilfield productivity, properties of reservoir, liquids and gases that are saturating the hydrocarbon-bearing horizon can be used to calculate development parameters for Korolev field, including production well locations, drilling schedules, and to facilitate both long-term and short-term forecasting for the purposes of optimizing the hydrocarbon recovery from the field. The objective of this work is to assess the impact of adding 3 extra producing wells and find ways to optimize cumulative production with the least impact on the existing development plan by means of deeper understanding subsurface dynamic processes of the Korolev field. The challenge is a high degree of connectivity between wells in the productive formation throughout the field so that any change of production parameters affects the whole field’s cumulative production. Trying to find a solution to optimum production of the reservoir forecast studies were carried out, the impact of each new well on development parameters was defined, sub-surface processes changes due to extra producers lead-in were explained and as a result of this thesis two optimization models were proposed, one of which will bring nearly 9.7 million barrels more oil.


A study on heat transfer inside the wellbore during drilling operations
Apak, Esat Can; Özbayoğlu, Evren; Department of Petroleum and Natural Gas Engineering (2006)
Analysis of the drilling fluid temperature in a circulating well is the main objective of this study. Initially, an analytical temperature distribution model, which utilizes basic energy conservation principle, is presented for this purpose. A computer program is written in order to easily implement this model to different cases. Variables that have significant effect on temperature profile are observed. Since the verification of the analytical model is not probable for many cases, a computer program (ANSYS...

Güler, Nuri Ozan; Bağı, A. Suat; Department of Petroleum and Natural Gas Engineering (2004)
A computer program has been written to perform production optimization in submersible pump lifted wells.Production optimization was achieved by the principles of Nodal Analysis Technique which was applied between the reservoir and the wellhead ignoring the surface choke and separator.computer program has been written according to two lifting environment,which are:pumping with only liquid,pumping with both liquid and gas.
Development of helical tubular reactor for hydrogen producing photosynthetic bacteria
Sarı, Süleyman; Eroğlu, İnci; Department of Biotechnology (2007)
Photobiological hydrogen production from organic materials occurs with the help of illumination and under aerobic conditions within photobioreactors. Novel designs are needed in order to increase the light conversion efficiency and to improve the biological hydrogen production. In this thesis, purple non sulfur bacteria Rhodobacter sphaeroides O.U. 001 was employed as the hydrogen producing microorganism. Two different types of photobioreactors, namely oscillatory helical photobioreactor and recycling helic...

In this thesis, a methodology to develop strength reduction factors for performance-based seismic design of bridges in far-fault seismic regions is presented. The presented methodology is mainly based on performing linear 5%-damped response spectrum analyses (RSA) and nonlinear time history analyses (NTHA) of bridge piers modeled as single degree of freedom (SDOF) systems. Bridge piers of both circular and rectangular sections are analyzed for wide ranges of various design parameters considering several sub...
Evaluation and modeling of streamflow data: entropy method, autoregressive models with asymmetric innovations and artifical neural networks
Şarlak, Nermin; Şorman, Ali Ünal; Department of Civil Engineering (2005)
In the first part of this study, two entropy methods under different distribution assumptions are examined on a network of stream gauging stations located in Kizilirmak Basin to rank the stations according to their level of importance. The stations are ranked by using two different entropy methods under different distributions. Thus, showing the effect of the distribution type on both entropy methods is aimed. In the second part of this study, autoregressive models with asymmetric innovations and an artific...
