Aims

Petrophysics is fundamental to understanding the properties of oil

and gas fields. It lies at the centre of all subsurface activities: whether

in the context of open-hole operations on new drill wells, cased-

hole operations on producing wells or in integrated team building

reservoir models for asset evaluation, field development or reservoir

management.

In this course emphasis will be placed on the integration of all

available data, understanding the context in which the data are

acquired and selection of appropriate methods and parameters.

Common pitfalls encountered in the interpretation process, and

their consequences, will be identified. Interpretation exercises are an

important element of the course.

Benefits

You will learn:

the role of petrophysics definitionsofthemainpetrophysicalparameters capillarity,fluiddistribution,freewaterlevelandfluidcontacts logging tool measurement principles and the effect of the borehole

environment log data quality assurance quick-look log interpretation data preparation, database construction and environmental

corrections deterministic petrophysical interpretation in clean and shaly sands deterministic interpretation in carbonates reporting and delivering results to other disciplines

Who should attend?

Reservoir engineers, geoscientists, petrophysicists and others involved in

the oil and gas subsurface management life cycle, with some experience

in formation evaluation, who wish to broaden their practical knowledge

and understanding of petrophysical data acquisition, quality control and

interpretation. Also numerate graduate entrants to these disciplines.

Duration 4 days

Course instructors

This course will be presented by Graham Webber.

Graham Webber is a Principal Petrophysicist in Senergys Edinburgh

office with more than 25 years experience gained in both operating

companies (including BP and Shell) and consultancies. Graham has

participated in multi-disciplinary teams engaged in exploration,

field development drilling, equity re-determination and reservoir

management.

Graham has managed petrophysical projects, supervised operational

log and core data acquisition and carried out technical assurance

for a range of field developments for both sandstone and carbonate

reservoirs. He has also provided mentoring and training in

petrophysics and petrophysical software.
