Mark Deakin is a technical consultant, author and Course Instructor in Petrophysical Data Integration and Renewable Energy. He holds a Ph.D. in ‘Integrated Petrophysics’ from London’s Imperial College, is an ex Amoco petrophysicist and has over 30 years’ experience, including 25 as a course instructor with PetroSkills and HOT Engineering. He has performed over 70 detailed reservoir studies worldwide; primarily in Southeast Asia’s low-contrast pay and carbonate & fractured reservoirs. Deakin’s approach is to identify and rank reserves uncertainties then guide companies towards defensible booked reserves and improved reservoir management via the application of new technology, targeted data acquisition and the systematic integration of all related data. After his PhD Deakin authored the first public Integrated Petrophysics course (1989) which evolved into the industry’s benchmark mainstream petrophysics training course. This was followed by courses in Carbonate & Fracture Petrophysics and focused modules on Quick Look Techniques; How to use SCAL with Modern Logs; Laminated & Low Resistivity Pay; Saturation Height; Using PetroDB with Modern Logs; Renewable Energy Primer; Geothermal Energy and Carbon Capture, Utilization & Storage. Deakin’s core interest is the integration of diverse technologies to solve problems. Since 2010 he has been increasingly drawn to the inevitability of renewable energy, writing his Renewable Energy Primer course in 2015. Current projects are developing his IPLAM, IPSWHT, REP, Geothermal and Carbon Capture (CCUS) courses. Deakin is an active member of SPWLA and occasional lecturer and course author at Edith Cowan and Curtin Universities. His consulting company PETROPHYSICS Pty Ltd has offices in Perth, Australia and he has homes in Australia and London.

Independent Asset Evaluation and Reserve Audits

Accurate knowledge of asset values is key to Mergers & Acquisitions, Private Equity and Hedge Fund investments in upstream oil & gas companies.  Investors are faced with technically challenging decisions and constantly changing technological scenarios.  A lack of technical understanding, misrepresentation and partial disclosure of key information pose the major risks to investors whilst hidden value can represent huge upside.  Uncovering and quantifying overstated or hidden value has been PETROPHYSICS’s specialty for over 25 years. Maintaining the edge over your competition rests upon recognizing the true value of an asset via efficient communication with a competent expert who is familiar with reserves uncertainty.  Assets which have undergone a significant (>25%) re-rating as a direct result of PETROPHYSIC’s independent audits are available upon request.

“Log analysis” was standard before the early 1990’s when “Integration” and “Petrophysics” become industry buzzwords. 1) 1984-1989 ‘Integrated Petrophysics’ PhD 2) Jan’90 ‘Integrated Petrophysics’ training course 3) Jan’90 onwards. Mainstream technical consulting & training 4) Jun’05  ‘Carbonates & Fracture Petrophysics – A Roadmap’ training course 5) Jan’06  PetroDB-Vault.  A core-log-test database intelligently crosslinked to the Vault evaluation command file.  

Prediction: the PetroDB-WEB linked petrophysical database will become the benchmark methodology for performing petrophysical evaluation.

If you seek clarity in developing S.E. Asia carbonates, complex or marginal fields consider PPL’s expertise in field development.  An experienced review of existing data, especially when supplemented by the PetroDB-Vault methodolgy, provides an inexpensive, unbiased and clearly documented basis for your further investment decisions.

The resulting 23% reserves upgrade was vigorously challenged by a rival operator, BP, who dispatched log analysis “experts” from Europe to challenge the study.  However, arbitrated by Petronas, the challenge was sucessfully defeated due to the core based, technically sound nature of the evaluation.  The asset value was increased by $100 million, dramatically increasing project profits and Triton’s book value.  (BP subsequently requested that I work with them in Jakarta to develop and implement this and similar ideas, see above)

PETROPHYSICIST, AMOCO London, 1988 – 1990

Worked as an already qualified petrophysicist in the Exploitation Dept in field development teams consisting of managers, geophysicists, geologists and reservoir engineers. Amethyst, Drake, Brent. Work embraced reservoir engineering and the field development economics. Projects included a Department of Energy gas/condensate Annex B, equity re-determinations and in-house sensitivity studies. Represented Amoco at equity meetings and worked on equity agreements. Role required knowledge of evolving petrophysical techniques and spanned exploration, reservoir geology, and reservoir engineering. Resigned (not laid-off !) following repeated offers for over 12 months consulting projects and a contract with TerraSciences software to build and supply a (then) powerful  PC with TerraStation licensed log evaluation software in exchange for developing “Integrated Petrophysics” Ph.D (see below)

Often neglected, inter-departmental skills reduce risk and enhance oil company profits. Since my PhD in 1985 my career has focused on filling this then neglected, but now established approach to reservoir problem solving.


University of Reading: B.Sc. Honours Degree in Geology. Mudlogger, Wellsite Geologist and Amoco after BSc during PhD 1989. Imperial College, London. Ph.D. thesis. Sponsor: Occidental Petroleum.

The Ph.D. research program outlined below was the response to a survey sent to 15 operating oil companies. The survey enquired of major shortcomings in formation evaluation.

Ph.D: Integration of Core, Log and Drill Stem Test Data for the Petrophysical Analysis of Brae Conglomerates, North Sea

The thesis provides a generalised method for the quantitative integration of cores, logs, RFTs, DSTs, SCAL, petrography, X-Ray diffraction, and SEM’s. The method creates Non-log-inputs from these data to integrate with the continuous log data. The resulting hybrid parameters enable high confidence lithology and fluids analysis from their rich information content, and a prediction of kcore and DST kh values. The need to reconcile apparently contradictory data provided the impetus for this research. The integration is based upon sound petrophysical theory, and provided a prototype template for solving a wide variety of problems, from the identification of Netpay in exploration wells, to the optimum exploitation of reservoirs with complex lithologies, pore geometry’s or other unusual features. All MSc Petroleum Engineering and Petroleum Geology courses were completed during Ph.D. studies.

The approach developed by this PhD formed the cornerstone of Deakin’s long career in integrating petrophysical data and began the movement away from 80’s stand-alone log analysis to quantitative petrophysical integration of diverse data. It has since been adopted by countless other companies, large and small, and has evolved into the industries standard for petrophysics, in part due to the 18 years and 1,000+ students of the IPRC training course
