Determining Reservoir Quality by Combined Stratigraphic, Petrographic and Petrophysical Methods; Sahel and Essomoud Fields, Sirt Basin

Abstract This study covers the Fields producting from the Gialo Formation a reservoir which is composed of Limestone and Dolomitic-Limestone and consists mainly of highly altered Nummulitic Packstone. This study was achieved through three parts of study including a petrographic study, petrophysical study of reservoir properties from core analysis and borehole logs. The general geological framework was obtained from petrographical study of thirty six thin sections, 129 representative core plug data and logs from 5 different wells are utilized to better understanding the petrophysical framework of the formation. The plots correlating petrophsical parameters and the frequency histograms suggested the presence of distinctive reservoir trends. These discriminations were also represented in Winland porosity- permeability cross plots resulted in clusters for different port-size that are responsible for different flow characteristics. Linear and multiple regression were used for the study of each unit. The permeability models were constructed and their reliabilies were compared by the regression coefficients for predictions in un-cored well. The combination of all data revealed the worst ranked reservoir quality corresponded to moldic and intergranular pore types, which occurred mainly in the Bioclastic Wackstone facies. The highest ranked reservoir quality corresponded to intragranular and intergranular which occurred mainly in the Nummulitic Packstone Facies.

Classification, Enhancement And Stability Of Backfill And Embankment Case Study: Tajoura – Misurata

Abstract Normally the study and investigated of earth material from the view of their uses as embankment and backfill material has a great importance in earth woks. This research concerns the assessment of earth masses and their properties which related embankment and backfill suitability as well as providing a mixing methods to upgrade the unsuitable within the accepted standards. The objectives of this research could be briefed by the investigation of earth masses along the study area which is governed by the distribution of superficial deposits comprehensive laboratory testing of soil samples molding Andes properties classification testing proctor and California bearing ratio recognition of suit able and non suit able backfill soil enhancement of unsuitable soil by mixing with other suitable soil such as quarry dust provided by nearby quarry correlation analysis and economic feasibility the study area is located in east of Tripoli from Tajoura to Misurata . This study manly concluded that as long as the poorly graded soil (A3) is difficult to be compacted according to the engineering properties of such soil are enhanced certainly by mixing with good sailable materials such as quarry dust. This research also conduced that the compaction properties will be enhanced by mixing where the optimum moister content is needed at the increase of maximum dry density. This research provides procedure of mixing design and recommendations for the mixing to achieve better results.

Analysis and Interpretation of the petrophysical properties of Mamuniyat reservoir in El-Feel Oil Field, western part of Murzuk Basin, NC-174, Libya

Abstract The sandstone of Upper Ordovician Mamuminyat Formation represents part of stratigraphic column in Murzuq Basin, south west Libya. It is the primary reservoir target in the basin, soursed and caped by Lower Silurian Tanezzuft Shale (Sola, 2000). The Mammuniyat reservoir in Murzuq Basin is characterized by lateral and vertical variation of petrophysical properties duo to lateral change of depositional environment and the digenetic effect on the formation load various facies deposition quality. The Concession NC174 is discovered in 1997 by Lasmo Grand Maghreb Limited then On the 26th October 2003 the development drilling campaign started by MOG till thepresent time. The El feel field is the major discovery in NC174. Porosity range is 16-18% and permeability some hundreds millidarcys. The Net thickness/Gross thickness ratio varies from 20% to 95% with an average value of 70%. The sedimentary fill in the Murzuq basin is mainly Paleozoic to Mesozoic in age and reaches a thickness of about 4000 meters in the depocenter. The sedimentary sequence is punctuated by several regional unconformities corresponding to successive tectonic activity phases. In the area of NC174, the tectonic phases developed anticlines and fault bounded anticlines generally super-imposed and re-actived through time. The resulting structural style is characterized mainly by poli-history sub-vertical reverse faults with different directions (N-S, NNW-SSE and NNE-SSW), these faults bound most of the prospects apparently superimposed on subtle anticlines oriented SSWNNE along which the culminations are aligne.
