Doctor of Philosophy

2020-2023: Norwegian University of Science and Technology (NTNU), Trondheim, Norway.

Thesis: Experimental and Numerical Study of Sub-sea Bulk Oil-Water Separation

Objectives:

Improvement, study, and numerical prediction of separation technology.
Evaluate experimentally the effect of surfactants, inlet choking, and presence of gas (air) on the separation performance, characterization of the droplet distribution along the separator, and experimental and numerical study of uneven flow splitting between branches.
Development of numerical models to match experimental measurements with the final goal of performing separator pre-design.

The main objective of this project is to study experimentally and numerically bulk oil-water separation in a parallel pipe separator for subsea applications. Compact seabed oil-water separation is a key technology that could enable, increase and prolong production from offshore oil and gas fields, increase energy efficiency, and reduce cost.

Thesis: Experimental Investigation of Gas/Liquid Cylindrical Cyclone Separator

Abstract: The Gas-Liquid Cylindrical Cyclone (GLCC) separators have proven themselves in the laboratory and field, as a well alternative to the conventional gravity-based gas/liquid separator. This study presents an investigation of the effect of changes in physical aspects on GLCC performance. These changes are including increases in outlet length and reduction in gas body column length, inlet, body column, and liquid and gas outlet diameter. Results show that a reduction in inlet diameter enhanced the GLCC performance but any reduction in the diameter of the body column and the liquid outlet has a negative effect on that. Also, changes in gas outlet diameter don’t influence on the GLCC flowrates domain. Any increase in the length of outlets rises the friction force and diminishes the performance of the separator.

The gas lock is one of the main problems of multiphase flow in separator risers. This thesis presents the results of comprehensive experimental studies on characteristics of gas lock-in riser that has been conducted on a transparent pipe with a 24.5 mm internal diameter for simulating the riser with variation in angle for 3 different riser angle. Flow regimes maps were presented for a range of obtained experimental data to show in which settings the gas lock has occurred in the riser. An examination of the experimental data conducted that the gas lock repetition frequency and Taylor bubble velocity increased with the gas superficial velocity. The Taylor bubble passage duration was observed to increase as the liquid and gas superficial velocity increased at 83° but was observed to be weakly dependent on them at 90°. The slug passage duration was also observed to decrease with an increase in gas and liquid superficial velocity. All of the empirical correlations have overpredicted the actual pressure drop in the riser.

Thesis: Simulation of Acidizing one of the Iranian South West Oil Wells

Abstract: Most Iranian petroleum reservoirs’ wells have problems with their high skin, so petroleum engineers have seriously tried to find an efficient solution to help the well to produce at the optimum flow rate, but doing a treatment without prediction and evaluation may harm the reservoir instead of helping. Pumping acid into the wellbore to remove near-well formation damage and other damaging substances, Matrix Acidizing, is one of those solutions that may help good production. Success in matrix acidizing depends on true evaluation and investigation of actions between rock minerals and acid fluids. This procedure commonly enhances production by increasing the effective well radius. When performed at pressures above the pressure required to fracture the formation, the procedure is often referred to as acid fracturing.

This project is going to (1) explain the well skin or damage and how it may happen in the well, (2) how acidizing treatment in the carbonate reservoir, (3)introduce the modeling equations that are used in carbonate acidizing, and at last (4) examine them on a real case with special acidizing software and compare with real welltest analysis data. The real case in this project has two welltest before and after an acidizing treatment. These tests give two different results in the correct way meaning the treatment was successful and skin has been reduced. It has been expected the software will predict skin reduction precisely.
