Greetings! My name is Sai Praveen Adiraju, I recently graduated with a Master of Science in Petroleum Engineering from The University of Tulsa. My thesis project was "Artificial Lift Applications in Unconventional Reservoirs". I've strong expertise in Production Engineering (Artificial Lift Selection) especially in electrical submersible pumps (ESP), solved few case studies of ESP operations and failures in horizontal wells using pipesim. I've strong background in two phase flow and transient multiphase flow in pipelines. I'm a good user of pipesim (steady state simulator), olga (transient simulation) and python softwares.

I'm currently working as a Research Assistant at Tulsa University Artificial Lift Projects. Most of my current work is related to product testing, product development and data analysis. I'm working on couple of projects, one of them is "ESP viscosity loop testing", the main objective of this project is to determine ESP pump performance degradation with change in fluid properties such as viscosity. Running experiments from 1cp to 1000 cp of oil viscosity to determine pump head performance degradation at various temperatures for different ESP's (specific speeds) and also developing dimensionless analysis using python to develop viscosity correction factor to mitigate viscosity effect on pump performance while designing. Another project is "Vortex Gas Separator (VGS) Testing", running experimental studies on the VGS  with various Gas to Liquid Ratios (GLR) from 50 scf/stb to 5000 scf/stb to determine separation efficiency of liquid and gas at different pressures. Experiments were carried out for various designs of VGS and determining efficiency to validate separator performance. Last project is "Artificial Lift Applications in Unconventional Reservoirs", running parametric studies, sensitivity analysis for production history matching to obtain reservoir parameters, utilizing best inflow performance relationship (IPR) for unconventional horizontal wells to forecast production rates, pump intake pressures. Determining reservoir pressures of the respective well based on production history using reserve engineering. Performing decline curve analysis using exponential declines, hyperbolic and harmonic declines, monitoring decline trend for unconventional wells and obtaining best match decline rate and incorporating it with IPR forecasting rates. The objectives of this project are to improve efficiency, applicability of artificial lift approaches. Developing an artificial lift selection tool, comparison of different artificial lifts in horizontal wells based on fluid properties, well characteristics, reservoir properties and artificial lift applications. Pipesim and olga are used for this project to make it successful. 

I've had other  internship experiences such as Field Engineer, Externship, Well Completions and Workover Operations intern, Subsea Engineer Intern...etc. I had couple of publications, one of them is my thesis which was published in the year 2023 and another publication is a research paper on "Sensitive analysis on tailpipe design for mitigating terrain slugs in horizontal wells".  

Apart from a good academics, I served as a Vice President of Graduate Student Association, Served as a Senator of Petroleum Engineering Department and was a committee member for Research Colloquium at The University of Tulsa where i gained leadership qualities such as integrity, decision making, perseverance and teamwork skills. I strongly believe apart from a good academic background, these qualities go a long way in shaping personalities and create efficient workforce running.

I'm currently looking for an Engineering Position in a team where I can utilize my problem-solving and innovative skills. I would like to be apart of the company which supports diversity, encourages professional development and has excellency in all aspects of work. I'm open to having a productive discussion about my background. I'm available for a quick interview any time, any day that suits you, I can be flexible and can adjust according to your schedule. 

Note: I'm open to travelling and relocating.
