But it would be telling us quite a lot already; for starting, we could think we are dealing with a parallel fold formed by flexural flow for example.
Structural Maps and Sections: Structural geology plays an important role in mineral and hydrocarbon exploration, and potential hazard identification and monitoring. Structural mapping is the identification and characterization of structural expression. Structures include faults, folds, synclines and anticlines and lineaments. Understanding structures is the key to interpreting crustal movements that have shaped the present terrain.
Structures can indicate potential locations of oil and gas reserves by characterizing both the underlying subsurface geometry of rock units and the amount of crustal deformation and stress experienced in a certain locale. Detailed examination of structure can be obtained by geophysical techniques such as seismic surveying.
Page 5 of 11 Structures are also examined for clues to crustal movement and potential hazards, such as earthquakes, landslides, and volcanic activity.
Identification of fault lines can facilitate land use planning by limiting construction over potentially dangerous zones of seismic activity. Therefore, we can best define Structure Map as a type of subsurface map whose contours represent the elevation of a particular formation, reservoir or geologic marker in space, such that folds, faults and other geologic structures are clearly displayed.
Its appearance is similar to that of a topographic map, but a topographic map displays elevations of the Earth's surface. There are several types of cross-sections but the most common in Petroleum Geology are as follows: Correlation Cross-Sections: They are the first figures to be drawn in the first phase of exploratory drilling and they enable the geologist to decide stratigraphic equivalences between the wells. Structural Cross-Sections: They show the present structural altitudes of rocks in relation to sea level as a horizontal datum.
Stratigraphic Cross Section: They show the correlation of strata with respect to one of them selected as a horizontal datum. Facies Map In geology, a facies is a body of rock with specified characteristics, which can be any observable attribute of rocks such as their overall appearance, composition, or condition of formation, and the changes that may occur in those attributes over a geographic area.
It is the sum total characteristics of a rock including its chemical, physical, and biological features that distinguishes it from adjacent rock. In other words, it can also be define as stratigraphic map indicating distribution of sedimentary facies within a specific geologic unit. Page 6 of 11 The purpose of facies map: The purpose of a facies map is to reconstruct paleogeography, from which we can predict reservoir, seal, and source rock distribution.
Facies maps are made at an isochronous surface or within a coeval interval. We map reservoir system thickness for two reasons: 1.
To compare the distribution of reservoir-system thickness and field location 2. To identify or predict locations with thick reservoirs and trapping conditions that are undrilled. A procedure for mapping facies: 1. Identify and correlate significant isochronous surfaces a line on a diagram or map connecting points relating to the same time or equal times throughout the depocenter, integrating well data, bioevents, and seismic reflection profile grids.
Map areas of potential reservoir and seal facies that occur between two isochronous surfaces. Map seismic facies associated with that interval.
Plot important physiographic features, such as the shelf-slope break or structurally controlled bathymetric highs. Integrate all data into a depositional facies map. Paleogeologic and Subcrop Maps: A map that shows the areal geology of an ancient surface at some time in the geologic past; esp.
Paleogeologic maps were introduced by Levorsen Therefore, we can simply define Paleogeology as the science that treats the geology as it was during various geologic periods. A map in the past that shows the paleogeology of an ancient surface is called a paleogeologic map. Page 7 of 11 Therefore, Subcrop maps shows what an area would look like if the topmost deposits would be removed.
It is therefore very useful for people such as well drillers, who are curious to know which rocks are present at a certain depth, instead of at the surface.
How do we differentiate Paleogeologic map from Subcrop maps? A subcrop map is a paleogeologic map in which the overlying formation is still present where as a paleogeologic map shows the formation boundaries projected in part into the area from which the overlying formation has been eroded.
If exposures of rock at the present-day erosion surface are referred to as outcrops, then rocks that were exposed at ancient erosion surfaces that are now buried are referred to as subcrops. Given that buried surfaces of erosion are unconformities, it follows that subcrops represent those rocks directly below an unconformity. If we strip away all the rocks above an unconformity, we can produce a map of the subcropping units, and this would constitute a paleogeologic map.
