| Summary, etc. | The Baltim gas fields, located offshore in the Nile Delta, are known for substantial gas <br/>condensate accumulations within the Pleistocene (El-Wastani Formation) and Pliocene (Kafr El-<br/>Sheikh Formation) reservoirs. This study aims to evaluate the hydrocarbon potential of these <br/>reservoirs by employing a comprehensive geophysical approach, incorporating seismic data <br/>interpretation, seismic inversion, and extended elastic impedance (EEI) modeling. The primary <br/>objective is to accurately identify gas-bearing zones, estimate Gas Initially In Place (GIIP), and <br/>propose optimal drilling locations to reduce exploration risks. The study begins with analyzing <br/>structural seismic attributes such as fault discontinuity and coherence, which were integrated to <br/>assess the compartmentalization and faulting characteristics of the reservoirs, critical for <br/>understanding hydrocarbon trapping mechanisms. Additionally, stratigraphic seismic attributes, <br/>including sweetness, reflection strength, and spectral decomposition, were used to delineate gas-<br/>bearing sands and channel fairways within the Pleistocene and Pliocene formations, with spectral <br/>decomposition helping identify significant channelized reservoirs with potential for gas <br/>accumulation. Post-stack seismic inversion techniques were applied to estimate gas volumes and <br/>refine the GIIP calculations, revealing significant gas accumulations in the target reservoirs. The <br/>GIIP for the Pleistocene anomaly was estimated at approximately 0.4 Gm³ (14.1 BCF), while the <br/>Pliocene anomaly exhibited an estimated GIIP of 32.87 BCF (0.93 Gm³) to 33.93 BCF (0.96 Gm³). <br/>Additionally, pre-stack seismic inversion and EEI analysis were employed to further characterize <br/>the lithology and refine the identification of gas-bearing sands, allowing for a more accurate <br/>estimation of reservoir properties, including porosity and water saturation. The Probability of <br/>Success (POS) for the Pleistocene gas-bearing sands increased from 49% to 69%, while for the <br/>Pliocene anomaly, the POS improved from 46% to 66%. These enhancements in success <br/>probability strongly support the potential of both reservoirs for gas production. Based on these <br/>results, it is recommended that an exploratory well be drilled in each anomaly to confirm the gas <br/>presence, and upon successful exploration, additional development wells can be drilled to <br/>maximize production from these promising gas reservoirs. |

| Summary, etc. | هدف هذه الدراسة إلى توصيف خزانات الغاز في حقل بلطيم بدقة، وذلك من خلال دمج السمات السيزمية (Seismic Attributes)، وتحليل السعة مقابل الإزاحة (AVO)، والانقلاب السيزمي (Seismic Inversion)، وتحليل الممانعة المرنة الممتدة (EEI)، مع بيانات التسجيلات البئرية. ركزت الدراسة على تكوينات العصر البلايستوسيني (الوسطاني) والعصر البليوسيني (تكوين كفر الشيخ) التي تحتوي على تراكمات غازية كبيرة.<br/>أظهرت النتائج فعالية دمج الطرق الجيوفيزيائية المتقدمة في تحسين تحديد الرمال الحاملة للغاز، وتقليل الغموض في التفسير، وزيادة احتمالية النجاح (POS) في عمليات الحفر المستقبلية. كما تم تقدير الغاز الأصلي في المكان (GIIP) لكل من شذوذات البلايستوسين والبليوسين، حيث بينت النتائج وجود إمكانات واعدة للحفر والتنمية في المنطقة. |
