Title: Seismic Sequences Stratigraphy Study in Sufyan Sub-basin Authors: Fathelrahman, Ahmed Ebrahem; Abd Allah, Ali Abd Allah; Jaafar, Mohammed Ali; Omer, Mohammed Elfateh Yousef; Supervisor, - Abbas Musa Yagoub Abstract: Stratigraphic interpretation process of the reflective seismic data which was done in Sufyan sub-basin in NW Muglad basin in East Darfur State. Seismic data represented by four 2-D seismic lines which include in-lines and cross-lines, the study area is mainly covers a part of Sufyan sub-basin. The study aims to identify the subsurface stratigraphic terminations and define the dominant stratigraphic termination in study area from the set of data available. Interpretation processes were done using Petrel version 2015software. Interpretation of the seismic sections was calibrated with the stratigraphic column of the Muglad basin. We found stratigraphic bodies such as (top-lap, down-lap, truncation and concordance). Description: Thesis

Title: Factors Influencing Wellbore Stability during Underbalanced Drilling Authors: KHALED, HASSAN MOHAMED HASSAN; ABDALMAOLAH, MUTAMN ISHAQ ABDALLAH; ALFADIL, MOHAMMED ALFADIL RAHMTALLAH; BASHER, MOHAMMED ALMOSTAFA ISMAIL; Supervisor, - ABD ALHAKAM ALTAYB MOHAMED Abstract: Underbalanced drilling (UBD) of vertical wells has been one of the efficient technologies in the exploration and development of oil and gas fields, while wellbore instability poses a problem during the whole operation process, for fluid seepage induced by the flow of formation fluid into wellbore exerts additional stresses on wellbore. However, the impact of fluid seepage has usually been ignored by conventional analysis of wellbore stability during UBD. This paper, taking the effects from fluid seepage into consideration, introduces a new collapse pressure model for UBD of horizontal wells. A comparison of the new model with the conventional one reveals that maximum equivalent collapse density (MECD) reduces with the decrease of borehole radius and that the wellbore is more stable in a slim hole during UBD of horizontal wells. And with the change of the inclination angle, MECD is higher when fluid seepage is considered under a certain relative azimuthal angle, indicating a narrower mud weight window and a more unstable wellbore; while the variation trend of MECD with the inclination angle are quite different at relative azimuthal angle =90_ and 0_. With the change of the relative azimuthal angle, MECD obtained in consideration of fluid seepage is also greater when the inclination angles is fixed, and MECD in both conditions (when fluid seepage is considered and) decreases with the increase of the relative azimuthal angle; meanwhile, the value of q where MECD is obtained is also analyzed.

Title: Evaluation of recovery efficiency and injection rate of waterflooding ‘five-spot’ pattern for a sudanese oil field Authors: Yosif, Abdelmoniem Abdelmagid Mohammedean; Ahmed, Mohammed Amer Mohammed; Elfaki, Mohammed Elfaki Omer; Altayeb, Mohammed Elfadil Abdalla; Bakheit, Safa Elemam Taha; Supervisor, - Satti Merghany Gaily Abstract: Water Flood Is A Mean Of Maintaining The Reservoir Pressure. It Improves The Sweep Efficiency For Oil And Accordingly Increases The Recovery Factor. Water flooding is very important in the oil field, therefore this research is designed to evaluate the water flooding for Heglig field in order to monitor the impact of water flooding on reservoir performance. In this research selction of suitable pilot area and designing for water flooding using the CMG.Therefore, several scenarios has been done to select the optimum method to increas the oil recovery of Heglig field. The results shows that water injection as inverted 5-spot ( 4 producer , 1 injector ) with injection rate of 1200 bbl in Heglig field sector model can increase the cumulative oil production from this area up to 1.5 million barrels.
