SPE Competency Management Tool (CMT)

Project Update, Fall 2014

10

11.2 Introduction

Drivers: Need for trained professionals rising with energy demand O&G industry losing experienced professionals to big crew-

change Limited number of graduating Engineers and Geoscientists How is the oil industry coping with these drivers? Hiring non-petroleum engineering graduates Emphasizing training and development Looking for ways to accelerate competency development

11

11.2 Board Guidance on SPE Role

Broaden training program to cover courses for all career stages

Offer a service where members can assess their own competencies, understand the gaps and engage in personal development through a self-paced learning program

CMT called for by the SPE Board Work Group on Lifelong Learning …

12

11.2 SPE’s CMT – Strategy

Help O&G industry address critical “Talent Gap” in a way that will: – Empower individual SPE members to do self assessments

– Identify gaps

– Develop a self-paced learning and development plan

– Leverage multiple training resources (Training Programs, SPE Books and Monographs, Technical Papers, Workshops, and Technical Conferences, SEG, etc.)

13

11.2 CMT Pilot – Summary

SPE considered three types of companies; Operating Co.’s, Service Co.’s, and EPC contractors; together they represent thousands of petro-technical jobs

The focus of the CMT Pilot phase is Operating Co.’s: –Scope limited to two career stages: Independent Contributor and

First-level Supervisor –Defined technical jobs covering a broad spectrum: –Partner with IHRDC; a reputable company with capability to deliver

SPE’s strategy

Pilot has been tested by SPE and now free to members

14

• Selects job title most closely aligned with their own

• Member progresses through a

self-assessment

• Assesses their skills against defined competency levels

19

• Clear description of knowledge and competence

• Self assesses their knowledge against the competency level

11.2 SPE CM Tool – Self-Assessment

20

• Determine and build their personal learning plan

• Member can track their progress against their selected competency model

• Can reassess themselves anytime

11.2 SPE CM Tool – Learning Plan

21

• Learning is hyperlinked to courses

• Leverages SPE training resources, books, monographs

• Can register from within the system

• Determine and build their personal learning plan

11.2 SPE CM Tool – Learning Plan

22

11.2 SPE CMT – Forward Plan

Gauge interest by usage tracking Identify gaps to develop more robust SPE training programs Add more jobs for broader appeal Monitor for enhancements and improvements Success defined by:

– Robust use – Detailed feed back from users

“Mindful organisations understand that long periods of success breed complacency and they are therefore wary of success. They are preoccupied with the possibility of failure. They hunt for lapses, errors and incongruencies, recognising that these may be the precursors to larger failures. They therefore have well developed systems for reporting near misses, process upsets and small and localised failures of all sorts. In short, they have well developed reporting cultures.”

CSIRO.

Schowalter (1979) shows that the capillary entry pressure:

(1) Pce =2γcosΘ/rt

where γ is the interfacial tension, Θ is the contact angle of hydrocarbon and water against the solid and rt is the radii of pore throats in the cap rock.

(2) PTp = ∆ρgH

where ∆ρ is the density contrast between the formation water and the hydrocarbon, g is the gravitational constant and H is the height of the hydrocarbon column above the Free Water Level (FWL) at the point the seal is breached.

Griffin and Chinook-Scindian Pools

http://www.pressureplot.com/

Perm of Griffin West and East faults is lower than Zeepaard and E will likely be production barrier.

Birdrong Aquifer looks in places to have low (disconnected?) oil saturation at Griffin.

Combination of Capillarity and Hydrodynamic drive and possibly a current oil slosh can explain pressure distributions.
