General Remarks

Be punctual: class attendance (maximum late 10 minutes)

Be quiet, set your hand phones in silent mode.

No chat, social networking or sleeping.

On each exam, you will be responsible for all material covered to that point in the course.

The date of the final is fixed. It is possible, but unlikely that the times of the other exams will be changed.


Dr. M.Ali

General Remarks

There will be no makeup of assessments. If you miss a test, you will receive a zero on the exam. unless (i) you notify me prior to the exam that you will miss it and (ii) have a medical excuse.

If late submission of assignments or other work is accepted, students will be penalised by ten percent per calendar day for a late assessment submission

You cannot pass this course without taking the final exam.

The University policy on attendance and cheating will be enforced

Syllabus






6. Pseudo functions


A type curve is a graphical representation of a particular,

highly idealised, theoretical, mathematical model of the

pressure response of the well-reservoir configuration during

a welltest procedure. Type curves are derived from

solutions to the flow equations under specific initial and

boundary conditions. For the sake of generality, type curves

are usually presented in dimensionless terms


Dr. M.Ali

Syllabus






6. Pseudo functions


The material balance equations can be derived by equating

masses of reservoir fluids that exist in and out of the

reservoir with respect to time during the producing life of a

hydrocarbon reservoir. Material balance can be performed

very easily by analyzing the pressure drop in the reservoir as

a result of fluid withdrawal from the reservoir.


Dr. M.Ali

Syllabus






6. Pseudo functions


In certain geological settings aquifers have been found that

are so large compared to the reservoirs they adjoin as to

appear infinite. This chapter will focus on reservoirs that are

in communication with large active aquifers, and will

quantify the effect this communication has on the reservoir

performance.


Dr. M.Ali

Syllabus






6. Pseudo functions


In any scientific or engineering application of analytical

methods, the approach is generally to set up the basic

theory of the subject, and its mathematical description in

one dimension. Such a description is provided through the

displacement theory of Buckley and Leverett. So, this

chapter describes analytical methods of calculating

recovery for an immiscible displacement process in porous

media.


Dr. M.Ali

Syllabus






6. Pseudo functions


Reservoir production performance analysis and forecasting

are fundamental responsibilities of the reservoir engineer

and lie at the heart of reserves determination. Several

techniques have been developed for the purpose of

production forecasting, ranging from simple curve fitting of

production data to the rigorous physical modelling of the

drive mechanisms over time (Decline Curve Analysis).


Dr. M.Ali

Syllabus






6. Pseudo functions


Immiscible displacement, most notably water displacing oil,

is a key physical phenomenon in many reservoir

developments. A thorough understanding of this topic is

essential for all reservoir engineers (Chapter3, 1D). This

chapter will now address the complexities of immiscible

fluid displacement on a reservoir scale and present

extensions of the analytical methods already developed.


Dr. M.Ali

Syllabus






6. Pseudo functions


Enhanced recovery refers to any of a variety of techniques

whereby energy is added to the reservoir in order to

increase the amount of oil and gas that can be economically

recovered from the reservoir. It is also called tertiary

recovery because it comes after natural and secondary

recoveries in the production order.

Course Objectives

Monitor and manage a hydrocarbon reservoir over long term.

Acquire in-depth technical knowledge of a number of important practical aspects of Reservoir Engineering.

Compared with the unit Fundamentals of Reservoir Engineering, this unit looks at a hydrocarbon reservoir from a broader but more practical perspective.


Dr. M.Ali

Course Outcomes

Describe the concept of reservoir engineering for conventional and unconventional reservoirs

Estimate hydrocarbon originally in place in the reservoir, using different methods such as, material balance, volumetric methods, and probabilistic method for different types of drive mechanisms


Dr. M.Ali

Course Outcomes

Use production decline analysis models to perform production forecasting

Use the Buckley and Leverett theory to evaluate water flooding performance

Apply Enhanced Oil Recovery (EOR) methods to increase ultimate recovery in various types of reservoirs
