Pore Pressure Analysis, Modelling and Prediction in Oil and Gas- OG 8007

7th June - 11th June 2021 (London, UK) 6th September - 10th September 2021 (Dubai, UAE) 22nd November - 26th November 2021 (Houston, Texas, USA.)

Course Overview

Pore Pressure Prediction is crucial to prepare a safe drilling program especially if the well will potentially intersect shallow gas zones or deep over pressured reservoirs associated to High temperature and pressured (HPHT) wells. A pore pressure model influences casing design, drilling mud weight, and mitigation of overpressure as a drilling hazard. This course is developed for reservoir geologists, geoscientists, drilling engineers and geophysicists and lithology analysts who want to equip themselves with the required knowledge of pore pressure modelling and prediction.

Learning Outcome

  • Understand the concept of pore pressure modelling and its relevance to oil and gas industry
  • Pressure and stress equations (stress, gradients and mud weights); overburden stress
  • Acquire more knowledge on subsurface fluid pressure trends, fluid contacts, hydrocarbon column height, fracture gradients and leak-off tests.
  • The work flow and required input data sets
  • Pore pressure, fracture gradient and mud weight
  • Understand the Losses, gains, ballooning and well breathing
  • Reservoir consideration, reservoir seal.
