Dr. Hemanta Mukherjee is the principal Consultant and President of iPoint LLC, with

more than 40 years of experience in the areas of oil and gas well production and

reservoir engineering. His company is an independent consulting company based in

Westminster, Colorado, serving several oil and gas production and service companies

through engineering consulting and training courses in various aspects of production,

well completion and reservoir engineering. Dr. Mukherjee holds a BS (Petroleum

Engineering) degree from the Indian School of Mines in Dhanbad, India; and MS and

PhD (Petroleum Engineering) degrees from ‘The University of Tulsa’, Oklahoma. He

retired from Schlumberger Oilfield Services in January 2005 as a Sr. Advisor,

Production Enhancement and Well Performance Optimization. He served in four

product lines of Schlumberger Oilfield Services and worked in the different regions of

the world. He is a visiting professor of Production Engineering for the Imperial College,

London for more than ten years - teaching the M.Sc Petroleum Engineering class every


Prior to joining Schlumberger, he spent two years as a research engineer in the

reservoir simulation department of Gulf Science and Technology Company, Harmarville,

Pittsburgh; four years as a Lecturer of Petroleum Engineering at the Indian School of

Mines in Dhanbad, India; and three years as a Field Engineer (Production) with the Oil

and Natural Gas Commission (O.N.G.C.), India. Dr Mukherjee has authored numerous

technical papers for reviewed journals in the areas of multiphase flow in pipes, well

management and well-bore hydraulics in reservoir simulation, Gas lift and other artificial

lift methods and design, diagnostics and troubleshooting of induced hydraulic fractures

especially in the fissured formations. He co-authored with Prof. James P. Brill the SPE

Monograph Volume 17 on “Multiphase Flow in Wells ". He was a SPE Distinguished

Lecturer in 1996-97, and received the SPE Production Engineering Award for the year

2000. He is a SPE Distinguished Member since 2004. He has also served in many SPE

committees over the past 30 years and chaired a few.

Full Description


This course is designed to provide an in-depth exposure to Artificial lift design-theory

and practice especially for Continuous Flow Gas Lift and Electrical Submersible Pump

(ESP). The course can also be modified for a five day exclusive ESP Training program

with hands on problem solving using the Software called SubPUMP. In either case,

adequate number of class problems are solved in the class workshops. Class problems

from the attendees are always welcome.

Day 4

ESP Design:

System (Nodal ) Analysis and Artificial Lift Review

o Pressure and Head determinations

o TDH Calculation method

o PVT Data needed for accurate design calculation

Steps necessary for an Optimum ESP installation

Critical Operating Conditions (how parameters like viscosity, water cut, and free gas

at pump intake affect the pump performance)

Pump and motor curves

Practical Considerations:

o Gas interference and free gas separation methods

o Variable speed: effect on productivity

o Importance of Fluid level data analysis on Pump performance

Overview of SubPUMP™ Software

Required Information and data to set up a base case for ESP design

System Preferences options used in SubPUMP™

Well system Components and operating conditions

Selecting best correlations for fluids and wellbore

Steps to select equipment based on industry best practices

Viscosity calculation and it’s effect

Gas interference in pump performance and handling

Setting design criteria:

o Pump Intake Conditions (the user enters design rate and pump depth. The

program calculates pump intake conditions

o Total Fluid Rate (the user enters pump intake conditions like Intake Pressure,

fluid level / fluid over the pump and pump depth. The program calculates Total

Fluid Rate

o Pump Depth (the user enters total fluid rate and one intake condition. The

program calculates pump depth)

Sensitivities to compare multiple vendors and operating parameters

Explanation of all Output Reports and Graphs

Day 5


Problem Set. Design and analysis of ESP installations are illustrated with several cases to

familiarize the user with the analysis modes and data entry process.

Calculation of required TDH for desired total rate: design process to find the required

TDH, pump intake conditions for a design rate. Illustrate the process of the selection

of pump, motor and cable. Consideration of motor slip.

Solving for pump depth: design an ESP for a deviated well. Find optimum depth to

install the ESP. Study the effect of compressed gas in stages and gas going back to

solution, use of viscosity calibration and viscosity correction factors in the design


Solving for Pump Intake conditions: Use of Vogel corrected for Water Cut IPR, effect

of motor slip, selection of a housing configuration, compressing gas in stages, use of

Sensitivity analysis on pump depth, adding pump derating factors to optimize

performance, motor heat rise calculations.

Analysis method: Use of ‘Analysis’ option for existing ESP installations. Doing

sensitivity on design frequency and pump selection, match current operating
