tapi kelihatannya artikel ini lebih banyak membahas
tentang karakteristik fisik dan mekanik batuan dan
struktur yang ada.
berikut saya kopikan abstraknya:
Abstract: Shale dykes, diapirs and mud volcanoes are
common in the onshore and offshore regions
of Brunei Darussalam. Outcrop examples show that shale
has intruded along both faults and tensile
fractures. Conventional models of overpressure-induced
brittle failure assume that pore pressure
and total stresses are independent of one another.
However, data worldwide and from Brunei show
that changes in pore pressure are coupled with changes
in total minimum horizontal stress. The pore
pressure/stress-coupling ratio (AO-h/APp) describes
the rate of change of minimum horizontal stress
magnitude with changing pore pressure. Minimum
horizontal stress measurements for a major offshore
field where undepleted pore pressures range from
normal to highly overpressured show a
pore pressure/stress-coupling ratio of 0.59. As a
consequence of pore pressure/stress coupling,
rocks can sustain a greater increase in pore pressure
prior to failure than predicted by the prevailing
values of pore pressure and stress. Pore
pressure/stress-coupling may favour the formation of
tensile fractures with increasing pore pressure rather
than reactivation of pre-existing faults.
Anthropogenically-induced tensile fracturing in
offshore Brunei supports this hypothesis.
