Overview

Public face to face and online courses 3 days. In-house courses may be amalgamated with other courses and delivered as 3 to 5 day courses however this should be done with caution.

What is PetroDB?

Transforms low cost wells into cored, tested wells.

PetroDB is the implementation of PetroDB-Vault, a fully flexible python coded evaluation command file (user app) linked to a rock-typed, 100,000 core plug petrophysical database, PetroDB.

IPPetroDB – Integrated Petrophysics with PetroDB is the training course which explains and demonstrates PetroDB functionality using a variety of Reservoir Types, J Types and Rock Types.  The course serves as an introduction on how to do exhaustively integrated, definitive petrophysical evaluations using all modern logs; the hard data contained in PetroDB; intelligently prompted AI findings and the petrophysicist’s own unique local knowledge all systematically pieced together with the PetroDB-Vault software.

Logs are interactively calibrated to rock-typed hard data and rival tools and techniques are compared and cross-calibrated to create a uniquely powerful formation evaluation tool. Calibration is performed via an internal 18+ parameter interactive diagnostic plot which selects data matched equations and parameters.

Three Default Evaluations plus a Synthetic bespoke option

The petrophysicsts is free to choose one of three parallel evaluations 1) PetroDB  2) Petrophysicist or  3) AI Generated and also to create an optional synthetic parameter by parameter combination of inputs and techniques. Vault automatically cross-calibrates rival inputs, tools and techniques by default, by reference to the petrophysicists own broad Reservoir Description Input Deck. However, the three default evaluations can be overruled by the petrophysicst and used to synthesize his/her own bespoke evaluation.

As a highly experienced and innovative petrophysicist himself the author understands that any automated processes can be very wrong and devastating to a company’s finances and also to the petrophysicst’s own reputation, especially in shaly sands, carbonates and fractured or complex reservoirs. PetroDB addreses this crucial need effectively, transparently.

PetroDB is your best answer at reducing petrophysical and geo-model uncertainty

PetroDB consists of over 100,000 rock-typed, routine core plugs, SCAL, formation pressures and well tests. These have been intelligently cross-referenced to basic geological information, conventional logs and modern special logs over 35 years of technical consulting and 70+ detailed reservoir studies.  The power of this petrophysical database is captured during petrophysical evaluation by it’s interface with PPL’s proprietary hierarchical evaluation command file, “Vault”.  Vault uses over 200 equations calibrated with Rock Typed specific relationships extracted from PetroDB.  In-out switchable modules use PetroDB data which meet selection criteria to calibrate that well’s available special logs including NMR, ADT, SSCAN and inverted log analysis equations to address each reservoir’s specific issues – this is integration!

Not a Black Box 

This PetroDB-Logs hard data integration is not a “black box push button” process run by a non reservoir aware computer operator! (often the case with expensive service companies)  It is expertly tailored to each reservoir via a fully transparent, documented process which can be challenged and modified at any point by a colleague, sceptical partner or adversary. This transparency renders the PetroDB evaluation understood, agreed and robust.

The AI assisted PetroDB provides an extremely flexible, convincing and uniquely powerful formation evaluation tool which may be applied to any well, reservoir or field; clastic, carbonate or fractured.

PetroDB-Vault – the benchmark evaluation for evidence-based decisions

Why are PetroDB results robust?  Because they result from of an agreed, transparent, hierarchical, hard-calibrated process rather than passive comparisons, with each step open to scrutiny and editable towards the agreed consensus.

PetroDB-Vault is not a “Black Box” like other sophisticated empty log analysis engines, Neural Network Machine Learning or AI auto-evaluations. All available data is meticulously integrated in fully transparent steps, understood, documented and agreed, including AI’s sometimes powerful findings.  “What If” scenarios can be run at will to satisfy difficult partners.

PetroDB is used routinely for all PETROPHYSICS Pty Ltd technical consulting projects. It is an ongoing software development project guided by advanced petrophysical understanding, critical thinking and real-world feedback.

Prediction: the PetroDB-Vault linked petrophysical database and AI transparent combo will become the benchmark methodology for performing petrophysical evaluation.

PetroDB : Big Data plus Intelligent Petrophysics

– facies
– tvdss
– geological age
– well tests produced fluids and k, kh
– conventional logs
– NMR logs
– miscellaneous hi-tech logs
– vshale, porosity, saturation, permeability, height above FWL (contact depth), capillary pressure
– shale total porosity
– normalized density-neutron separation
– normalized density-sonic separation
– bulk volume water
– bulk volume hydrocarbon
– moved HC volume
– bound fluid volume
– any combination of the above

Process..

– Client contacts PETROPHYSICS with specific questions regarding a well or field where data is insufficient to provide confident answers. For example,

• saturation or permeability are uncertain
• geomodel capillary pressure saturation-height function cannot be defined
• petrophysical audit is required (investment precursor)

– A hard data base of core and tests is identified by intelligent cross-referencing of basic geological information and conventional logs to assess task feasibility. The extent of the available hard data is communicated to client together with the defined Reservoir Task, Fixed Lump Cost and Time.

– When approved, PPL expertly integrates and interprets the found hard data to answer client’s specific questions.

– Finally, a brief Reservoir Task Report is produced including Results, Assumptions, Uncertainties, Recommendations & Figures.  The process is completed on time and within budget.

PPL will exploit all resources at it’s disposal to answer client questions and communicate findings effectively. Expensive “Black Box” results are rejected. PPL will then endeavor to work with client to effectively implement the Reservoir Task results.
