Well Integrity - How and When?

This type of matrix approach suggested is notdifficult to generate or apply, but needs:

management commitment

systematic thinking

a base of standards and procedures

a competent, controlled, systematic and pragmaticapproach to dispensation and risk assessment

focused application


23/46

Formation Damage

Formation Damage can be defined as anyreduction in near wellbore permeability which isthe result of any stuff we do

.such as drilling, completion,

production, injection, attempted stimulation or

any other well intervention


24/46

What is the impact of damage?

Shell has estimated that at oil price of less than $20 /barrel the cost of damage on Shell operated assets was$1 billion / year. Shell, at that time, was producing roughly3.3 % of total world production.

A $35 / barrel and global perspective means current bestestimate for cost of damage due to deferred production

and dealing with damage is $50,000,000,000 / year

At current $100+ prices ..!!!

What is CFD?

The science of predicting fluid flow, heat &mass transfer, chemical reactions and relatedphenomena by solving numerically the set ofgoverning mathematical equations

Domain is discretised into a finite set ofcontrol volumes (cells)

General conservation transport equationsfor mass, momentum, energy are solved foreach cell

Partial differential equations are discretisedinto a system of algebraic equations

All algebraic equations are solvednumerically to render the solution field
