Skills

Knowledge

Awareness

This course is aimed at providing a review of theory and latest thinking for planning wells i.e. PP/FG and Geomechanics as well as reviewing how critical pressure data is if used correctly in the cycle of an oilfield, from initial discovery to development of the accumulation.

As such, it is suitable for G&G, operations and drilling communities. One main focus is how the geology of a basin must be integrated in order to achieve best results.

Course Content

Data, definitions and datums
Overburden stress calculation
Wireline formation test interpretation
Pore pressure in the overburden
The causes of overpressure in a basin
Fracture pressure models
Understanding realistic geological uncertainty
Oil field geomechanics
Rock mechanical properties and core testing
Horizontal stress anisotropy and wellbore stability
Seal capacity and column heights, the eﬀects of overpressure on AVO models, overpressure mapping and fault seal, lateral drainage and hydrodynamics

Session 1 - Basics of Well Planning

DISCUSSION – Setting the scene in terms of understanding the needs of an operator and how PP/FG should be approached as Best Practice. As such, it is suitable for G&G, operations and drilling communities. One main focus is how the geology of a basin must be integrated in order to achieve best results.

Session 2 - Methods of Pore Pressure Prediction

DISCUSSION – “Drillers pore pressure vs geological pore pressure and what is needed by the drillers from the geologists.”

Session 3 - Oil field geomechanics

WORKSHOP – An opportunity for operators to highlight any geomechanical issues faced and discuss practical, cost effective means of addressing these.

Session 4 - Rock mechanical properties and core testing

DISCUSSION – How you do develop a fit for purpose rock property data base in a field, how to overcome data constraints?

Session 5 - Horizontal stress anisotropy and wellbore stability

DISCUSSION – Minimising well construction problems and optimising casing size through understanding instability issues.
