Course 02 Core Drivers

The Well Productivity ProgrammePrimary Factors Impacting Productivity

Two wells in the same reservoir can perform worlds apart. This course works through the factors that decide how much of a reservoir's potential actually reaches the wellbore — what you inherit from the rock, and what you design into the well.

Refined over 15 years of classroom delivery to national and international operators, now rebuilt as a problem-based, self-contained online programme for working petroleum engineers.

What you'll be able to do

Separate the factors you inherit from the ones you control

Course 02 explains why two similar wells perform differently, and which of those reasons an engineer can actually influence. You learn to attribute lost productivity to the right cause before reaching for a fix.

Read the architecture

Trace how heterogeneity, natural fractures, partial completion and deviation each add to skin.

Account for multiphase

Anticipate phase behaviour and diagnose gas wells that load up with liquid as pressure depletes.

Respect the geometry

Judge how much wellbore radius really matters, and where mechanical limits cap productivity.

Design the perforations

Specify geometry, phasing and charges that punch past drilling damage into clean rock.

Four families of primary factors

Some factors you inherit from the rock; others you engineer into the well. Each module isolates one family and shows exactly how it moves the productivity index, for better or worse.

Perforating Design

Engineering the tunnels that connect well to reservoir, and getting past drilling damage.

  • T01Geometric Factors of Perforating
  • T02Bypassing Drilling Damage
  • T03The Crushed Zone and Perforation Clean-up
  • T04Charge Selection based on Rock Strength

Who this course is for

  • Production and completion engineers diagnosing why wells underperform expectation.
  • Reservoir and petrophysics staff connecting rock properties to deliverability.
  • Engineers specifying perforation and completion design for new and recompleted wells.
  • Anyone who has completed Course 01 and wants to understand what drives the IPR.

What you leave with

  • The ability to attribute skin to architecture, completion geometry or deviation.
  • A method for recognising and remedying liquid loading using critical velocity and foam.
  • A realistic view of when hole size genuinely changes productivity, and when it doesn't.
  • Perforation design logic: phasing, penetration, crushed-zone clean-up and charge selection.
How it's taught

Problem-based, not slide-based

Every module opens with a real well problem. You work the engineering, then the theory is introduced to explain what you found: the way the material was honed in the classroom over fifteen years.

01

Start with a well

Each topic is anchored to a field scenario with real data, not an abstract derivation.

02

Work the problem

You isolate the factor at play and quantify its effect, then the theory frames why.

03

Carry it forward

The drivers you learn here feed directly into the diagnostics and remediation courses.
