Integrated AVO inversion and seismic attributes for tracing hydrocarbon accumulation in Kafr El-Sheikh Formation, South Batra field, Nile Delta, Egypt: A case study
نویسندگان
چکیده
Utilizing advanced seismic techniques for delineating hydrocarbon accumulations in HST (High Stand System Tract) turbidite channel of Kafr El-Sheikh (KS) formation (Pliocene Age) located the western part South Batra field (SBF), Nile Delta – Egypt is investigated. 3D data and four well logs helped studying properties channel. Three wells encountered central showed thicker reservoir thickness than fourth well, which levee. The characterized by high porosity (25–30%) relatively low water saturation (27–50%). structural map that dipping towards NE–SW. AVO analysis, scaled Poisson's ratio, post-stack inversion, attributes confirmed presence Class III gas sand. Variance attribute imaging faults. Maps generated from spectral decomposition dominant frequency around 15 hertz. Results integrating different were consistent successfully determining geometry channel, discriminating between lithologies fluids, addition to sweet spots recommended locations drilling.

Ruminant Brucellosis in the Kafr El Sheikh Governorate of the Nile Delta, Egypt: Prevalence of a Neglected Zoonosis
BACKGROUND Brucellosis is a neglected tropical zoonosis allegedly reemerging in Middle Eastern countries. Infected ruminants are the primary source of human infection; consequently, estimates of the frequency of ruminant brucellosis are useful elements for building effective control strategies. Unfortunately, these estimates are lacking in most Middle East countries including Egypt. Our objecti...

BACKGROUND/OBJECTIVES Scabies is a major global public health issue that might affect people from all socioeconomic levels. The primary contributing factors in contracting scabies seem to be poverty and overcrowded living conditions. Scabies often spreads among schoolchildren quite rapidly, owing to their close contact and overcrowding within the schools. However, limited information is availab...

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Amplitude versus Offset (AVO) Technique for Light Hydrocarbon Exploration: A Case Study
AVO as a known methodology is used to identify fluid type and reservoir lithology in subsurface exploration. Method discussed in this paper, consists of three stages, including: Direct modeling, Inverse modeling and Cross plot interpretation. By direct modeling we can clarify lithology or fluid dependent attributes. Analysis performed using both P-P and P-Sv attributes. Inverse modeling deals w...
