Exercise Chapter 8:

THE HABITAT OF HC IN SEDIMENT BASINS

1/ Give one example in which a basin's depocenter, its topographic low point,

and its point of maximum basement subsidence will not, in all likelihood,

coincide

2/ Relate the following features to either convergent or divergent plate tectonic

processes:

A upwelling in the asthenosphere

B suture zone

C failed arm rift

D large-scale transcurrent (strike-slip) fault motion

E active continental margin

F passive continental margin

3/ What is the sequence of events which leads to the development of a new

ocean basin and the splitting apart of continents?

4/

1 Name the two basin types, among the ten developed in our

classification scheme, that dominate world's conventional petroleum reserves

2 Name the three basin types that only rarely have yielded giant-field production and which do not occur among the world's most petroleum-rich

basins

5/

5.1 What two major groups of basins, each containing several of our ten basin types, yield petroleum mostly from shallow wells, at depths of less than 2 kilometers?

5.2Which two of the ten basin types usually produce petroleum from depths exceeding 3 kilometers or more?

1

6/ What two basinal settings lead to enrichment in natural gas?

7/ What is required in order to obtain giant gas fields in a basin?

8/Using the classification scheme developed in Sections 7.6 to 7.11, name the

basin type(s) associated with each of these regions:

A — California

B _ — the continental shelf off eastern North and South America

C — small oceans and inland seas

D — Precambrian shield areas with low, peneplained

topography

E — both the Andes Mountains of South America and the Tethyan trend (Alpine Mountains to Himalayas)

F — point where a failed arm rift meets an ocean basin

G — the Pacific "Ring of Fire" island-arcs

9/ Name the two types of cratonic basins

Which of the two usually has the greater petroleum potential?

10/ Sketch the geometry of the following basin types in the boxes , both in map

view and cross section ( Figure 1)
