The purpose of the study is to understand the petro physical behavior of reservoir rocks of Lower Goru Sands in Kadanwari 01, 03, 10 and 11 well. Three tectonic events configure the Kadanwari field. First in the late Cretaceous uplift and erosion, the axis of uplift appears to be oriented NNE-SSW. The second is right letral wrench faults, which basement rooted. These have general NNW-SSE orientation and exhibit flower structure. The third event is Late Tertiary to recent uplift Jacobabad High having a major influence on the Kadanwari, due those structural traps formed in the area. Research involves the petrophysical analysis of reservoir rocks using wire line logs. Petrophysical study includes shale volume, porosity, permeability, water and hydrocarbon saturation and correlation. By contouring thickness trend is seems that the depositional strike at the time of deposition of Lower Goru is in N-S direction in general. Possible presence of high percentage of chamosite mineral affect the reservoir quality at different intervals.

The data, which is taken for the study, is of Makran Block. Data is provided by Pakistan Petroleum Limited. 2D seismic data of this area is limited and not able to provide detailed information regarding the internal structure of the area therefore the 3D data is taken. The Makran Block 3D seismic data comprises of 2084 km2 of area. ! ! In this study, the structural settings of the Makran Accretionary Prism have been studied through the 3D seismic data of Makran Block. The data is very complex as the area is highly compressive. Major part of the data is chaotic and not clearly visible. Some reflections have been picked from the visible part of data. Faults have been marked too in the sections. i Faults presented in the most of the area are imbricate thrust faults, which are over laid by some over turned folds making the fault bend fold structures. These can be seen between 2500 ms to 4500 ms in the sections. Gas chimneys are also visible in the data, which indicates the presence of hydrocarbons. Bright spots on the seismic lines have been marked and can be used as evidence for hydrocarbon potential.

The earthquakes at Makran have a history of 600 years (1438-2015). The tectonic earthquakes caused by the geological system in Makran. The characteristic seismicity is associated with the subduction of Arabian underneath Eurasian plate occurs in North Arabian Sea, along the coastal areas of Pakistan and Iran. (Approximately 1000 km, along N-S). The study area is characterized with high and low seismicity in eastern and western parts, shallow and deep focus earthquakes in Northern and Southern parts, cause severe damage after tsunami along coast. The geospatial distribution of earthquakes suggests there is a shift in seismicity of Makran over local coordinates in last century. It seems that the stresses are initially build/transferred from frontal Makran/offshore (Subduction Zone) and released in other parts to the North, East and West. Major earthquakes in Makran subduction zones are tsunamigenic and have a long tail of aftershocks of shallow to deep focal depths. The coastal areas of Makran (Jiwani, Gwadar, Pasni, Ormara and Gadani) are important centres of sea-trade and socio-economic system. The new ventures of development, urbanization, exploitation of mining for economic minerals, and exploration for hydrocarbons in offshore Makran demand recent studies on seismicity. A potential earthquake in Makran may snatch the beauty of fascinating sea ports and turn the under developed projects into rubbles. Makran is considered as a special case for the researchers due to its low seismicity but has a potential to shake the ground with maximum release of strain energy. The statistical, seismological and geological results of this study may guide the researchers, explorationists, planners and students because this study provides a link between geology and geophysical characteristics of Makran through data integration Supervised by Dr. Mubarak Ali Sun, 01 Jan 2012 00:00:00 GMT http://hdl.handle.net/123456789/9299 2012-01-01T00:00:00Z http://hdl.handle.net/123456789/9298 3D SEISMIC INTERPRETATION OF MAKRAN OFFSHORE, PAKISTAN Mahmud, Shaista Makran Accretionary Prism was formed due to the subduction of Arabian Plate under the Eurasian plate. It is an exceptionally large prism trending east to west and is formed by the sediments scrapped off the Arabian Plate. High convergence velocity coupled with a high sedimentation rate owes to its complex architecture. Presence of a petroleum system is also evident in the area and this fact has made Makran a potential area for exploration. The structural interpretation of the Makran central block offshore Pasni/Gwadar, Pakistan is done in this thesis work. A 2100 km2 of 3D seismic data, provided by Pakistam Petroleum Limited, is analyzed and interpreted. The data is analyzes and interpreted on SeisVision, an interpretation module of GeoGraphix Discovery suite, and the maps displayed on another inlines,fourcrosslines and one arbitrary lines, is analyzed and interpreted. Well data from two wells Pasni 1 and Pasni X2 is also incorporated while interpreting the lines. The structural interpretation shows a series of imbricate thrust faults below an unconformity. Folding is fault related and has resulted in forming an anticlinal structure truncating against thrust faults. The decollement level couldnot be marked on the lines due to a poor quality of 3D seismic data. However, according to other studies it is located at 5-7 km below the surface.The presence of gas chimneys on the inlines also indicate an active hydrocarbon system for the Makran Offshore.
