Assessing the possibility of gas leakage through drilling induced fractures in shallow formations
Authors: A. Tsopela, G. de Bruin, A. Moghadam, N. Versteijlen, Dr. M. Wilpshaar
What is the hypothesis? In recent literature it is proposed that drilling always creates fractures around the wellbore (drilling induced fractures) that serve as migration pathway for gas in shallow (< 1000 m depth) sediments. This...

Property prediction of Plio-Pleistocene sediments in the A15 shallow gas systems
Authors: Dr. J.H. ten Veen, Drs. C. Geel, G. Kunakbayeva, Dr. T. Donders, Dr. R. Verreussel
This report describes a best-practise workflow for assessment of the distribution and properties of both bright-spot occurrences and their hosting sediments, i.e. the shallow gas plays, in the Southern North Sea. The A15 block was selected...
