ННІ «Інститут геології» запрошує студентів, викладачів та науковців відвідати 27 квітня 2016 року лекції Стюарта Харкера (Великобританія) в рамках програми AAPG Visiting Geoscientist.

Лекції відбудуться в аудиторії 422:

• о 10-30: Geoscientist roles in the search for petroleum resources
• о 12-20: A success story of finding and exploiting new resources in an old producing basin

Лекції будуть присвячені наступним питанням:

1. Geoscientist roles in the search for petroleum resources.
   
   • What is involved in the search for petroleum with examples of geoscientist jobs, and what is needed, what the job involves, relationships with other disciplines, career paths, etc.

   Abstract

   This presentation contains a brief account of what is involved in the search for oil and gas, including a synopsis of the author’s 40+ year petroleum industry career. The majority of the talk deals with the variety of what the over 20 roles that a geoscientist can take though a career, from mudlogger, through sedimentologist, seismic interpreter, production geologist to independent expert in unitization. What is needed to fulfill those roles and integration with other disciplines in each role are illustrated. Also included is personal experience on maintaining an open mind and the testing of new ideas, as well as thoughts on geoscience university course content.

2. A success story of finding and exploiting new resources in an old producing basin.
   
   • Example of gas discoveries in the Rharb Basin, Morocco.

   Abstract

   The Rharb Basin is situated midway between Tangier in the north on the Mediterranean coast and the Moroccan capital of Rabat to the south on the Atlantic coast. The basin contains over 3000m of Late Tertiary clastic sediments. A sequence stratigraphic approach was used to subdivide the Late Tertiary “Productive Series” of the basin, with the definition of 8 distinct units. The Mio-Pliocene mudrock depocentre contains thin good reservoir quality gas-bearing sands. The seismic response of the gas sands shows up as bright negative amplitudes on the 3D seismic, as the gas content lowers the density and slows the seismic velocity. Earlier exploration had been conducted using widely spaced 2D seismic data and led to a few discoveries, proving the existence of a working petroleum system. Detailed interpretation of the 3D seismic delineated the location and geometry of the anomalies for drilling targets. The gas sands are contained in combination structural-stratigraphic pinchout traps with both footwall and hanging wall structures present. Co-eval marls and shales provide top, bottom and lateral seals.
