Petroleum Engineer CDR Example: Senior (Drilling and LWD)
Petroleum Engineer · Field engineer and PSD manager
About this CDR
Three Career Episodes from a senior petroleum engineer at a multinational oilfield services company: logging while drilling and geosteering through an oil reservoir while keeping the circulating density inside the safe window, a corrosion inhibition programme for drill collars and downhole tools on a multi-rig campaign, and a drillstring dynamics study that cut shocks, vibration and tool repair costs. This CDR was assessed and approved by Engineers Australia under the Professional Engineer (PE) competency standard.
How to use this CDR
Use this CDR as a guide to the structure, technical detail and writing style that Engineers Australia assessors accept, then write your own Career Episodes about your own projects, in your own words. This CDR was written entirely by a human writer, with no AI tools used at any stage.
Complete CDR: Career Episodes, Summary Statement and CPD
You receive all five documents below as editable Word files.
LWD Logging and Geosteering on an Oil Well
As senior field engineer, logged gamma ray, resistivity, density and porosity while drilling, geosteered close to the oil and gas contact to maximise production, and kept the equivalent static and circulating densities inside the safe drilling window.
Corrosion Inhibition Programme for Drilling Tools
As job delivery lead on a five-rig drilling campaign, designed a corrosion inhibition programme to protect drill collars and downhole tools, wrote corrosion control guidelines and led the field team that put them into practice.
Shock and Vibration Reduction in Drilling
As product and service delivery manager, analysed high shock and vibration levels that caused tool failures and non-productive time, ran drillstring dynamics modelling, changed the BHA design and drilling parameters, and reduced repair costs for the company and its clients.
Summary Statement
Maps all 16 Professional Engineer competency elements (PE1.1 to PE3.6) to the exact paragraphs in the three Career Episodes where it is demonstrated, so the assessor can check each element quickly.
Continuing Professional Development (CPD)
A list of the professional development completed since graduation, such as courses, training, conferences, seminars and self-study, set out in the format Engineers Australia asks for.
