PEI Knowledge
PEI organises petroleum engineering knowledge into a structured technical foundation covering principles, methods, equations, workflows, references and professional judgement.
The objective is not to accumulate information. It is to keep technical knowledge understandable, relevant and usable within its intended engineering context.
Knowledge foundation
PEI is not intended to reproduce a university curriculum or function as a general petroleum engineering textbook. Its knowledge structure is organised around the technical material required to understand and support real engineering work.
A principle, equation, method or reference has value not simply because it exists, but because its technical purpose and conditions of use can be understood.
Physical and engineering principles that explain how petroleum systems, reservoirs, wells and production systems behave.
Examples
Recognised analytical and computational methods used to investigate and evaluate petroleum engineering problems.
Examples
Structured technical activities that organise how engineering knowledge is applied to recurring problems.
Examples
Established equations and calculation relationships that provide the quantitative foundation for engineering analysis.
Examples
Recognised technical literature, standards, manuals and other reference material supporting petroleum engineering practice.
Examples
Professional interpretation used to understand limitations, weigh technical considerations and determine what the available basis supports.
Examples
Knowledge governance
Petroleum engineering knowledge comes from many sources. PEI therefore considers the quality and suitability of technical material as part of maintaining a reliable knowledge foundation.
Technical material should come from recognised and appropriate sources for the subject being addressed.
A technically authoritative source is not automatically relevant to every petroleum engineering problem.
Knowledge must be considered in relation to the physical system, operating conditions and intended use.
Important technical claims should retain sufficient provenance to identify their underlying source.
Standards, correlations, references and technical procedures can change and should be treated as controlled knowledge where appropriate.
Technical material should be used in accordance with applicable licensing, copyright, contractual and confidentiality requirements.
Lifecycle knowledge
The technical knowledge relevant to an asset changes throughout its lifecycle. PEI therefore organises knowledge around the major stages of upstream petroleum engineering.
The lifecycle provides context for the type of technical knowledge required while allowing shared engineering principles to connect different disciplines.
Petroleum-system, geological, geophysical and subsurface information used to identify and evaluate prospects.
Well, log, core, fluid and pressure information used to evaluate a discovered accumulation.
Integrated geological, petrophysical, fluid and reservoir engineering understanding of the reservoir.
Reservoir and well knowledge used to evaluate development concepts, well strategies and production plans.
Engineering knowledge applied to well objectives, trajectories, pressure regimes, drilling and well integrity.
Formation and well information applied to completion architecture, stimulation and production readiness.
Pressure and rate behaviour used to evaluate reservoir and well performance.
Reservoir, wellbore, completion, artificial lift and surface knowledge applied to production performance.
Field performance knowledge used to diagnose behaviour, monitor changes and identify optimisation opportunities.
Reservoir behaviour, recovery mechanisms and technical knowledge used to evaluate improved recovery strategies.
Technical foundation
The PEI knowledge foundation should draw from recognised petroleum engineering knowledge, appropriate industry practice, authorised field information and validated engineering work.
The appropriate source depends on the technical subject and intended use. A source should therefore be considered in its proper engineering context.
Knowledge sources
Knowledge discipline
Technical knowledge becomes unreliable when assumptions are presented as facts, generic values are treated as field data, or engineering methods are separated from their intended conditions.
A disciplined knowledge foundation keeps these distinctions explicit and makes technical material easier to use appropriately.
Knowledge boundaries
Not every technical question can be answered from general engineering knowledge. Some problems require asset-specific measurements, laboratory work, specialist studies, additional testing or professional engineering judgement.
PEI should therefore distinguish established technical knowledge from asset-specific information and recognise when the available knowledge is insufficient for the question being considered.
