NPA has launched
a new Zagros study that will combine the skills of the companies
to guide exploration in the Persian Carpet region. In addition
to NPA’s regional interpretation, the new study will
incorporate more detailed structural analysis of fold growth,
fold-fault linkage, the role of decollement and fault reactivation
and consideration of whether thick or thin-skinned models can
best describe the deformation imaged at the surface. Where
possible these themes will be illustrated using 3-D perspective
views, detailed image analysis and by comparison to worldwide
analogues.
Offshore Basin Screening in the Zagros
Region
These themes will be fed back into
a petroleum perspective to provide the subscriber with a structurally
up-to-date look at the petroleum prospectivity of the Zagros
region. The customer can engage this level of service at either
regional or more focused, licence block scales. The onshore
interpretation forms the basis of NPA’s new Persian
Carpet study, which combines Offshore
Basin Screening (OBS) and Thermal Basin Screening (TBS)
technologies into the regional Petroleum assessment.
Zagros TM tectono-stratigraphic Study
Zagros Tectono-Stratigraphic Interpretation
of Landsat TM data
The study extends from
the Lut Block in SE Iran to the Mosul Block in northern Iraq.
It covers the internal as well as
the external zones of the thrust-system and maps structures
not present on the NIOC maps. Stratigraphy from these and
Iraqi maps have been integrated into the study to provide
a highly detailed continuous and consistent geological
map of the entire Zagros Mountains.
The study identifies previously unmapped
structures in the Fars Simple Fold belt, such as N-S reactivated
basement faults, and in the Dezful and Kirkuk Embayments where
we have mapped subtle structures not evident from the ground.
The nature of the thrust system and the different types of
related structure (imbricate stacks to simple detachment folds)
are shown and described using contemporary fault-related fold
geometries and concepts. These ideas are illustrated as a
series of regional cross-sections. Also discussed are the
reasons for the concentration of hydrocarbons in the Dezful
and Kirkuk Embayments and the role of N-S basement structures
in segmentation of the thrust system.
