Petrographic Description

This paper sheds light on the role of petrophysical properties, framework grains and its textural properties, capillary pressure, diagenetic constitutions and events as controlling factors in evolving sandstone quality of the Khatatba Formation in the Western Desert, Egypt. Petrophysical analyses coupled with petrographic observations and diagentic studies have been carried out for many core samples in order to infer the controlling factors of reservoir quality. It has been observed that the sandstone quality of the Khatatba Formation have been adversely affected from well to well in the study area and from zone to zone in the same well and formation. Good- quality sandstones have been found with the porosity ranges from 10–17% and permeability ranges from 100 –1000 mD. The petrographic description indicates the presence of many open hydraulic fractures and dissolution phenomena which all took place in multiple phases during the late diagenetic stage, leading to improvement in the reservoir quality. Dramatic reservoir quality deterioration has been recorded in many zones. The reduction of permeability and fluid pathways in addition to the mechanical compaction, solid bitumen occupying many pore spaces and fractures are observed in many zones. These cause major destroy in reservoir quality that leading to lowering the oil recovery  compare to the expected outcome

This article introduces Cognitive Health Counseling 40+ (CH.CO40+), an individualized intervention that is conceptually based on the orchestration model of quality-of-life management ( Martin & Kliegel, 2010 ) and aims at improving satisfaction with cognitive health in adults aged 40 years and older. We describe the theoretically deduced characteristics of CH.CO40+, its target group, its multifactorial nature, its individualization, the application of subjective and objective measures, the role of participants as agents of change, and the rationale for choosing participants’ satisfaction with their cognitive health as main outcome variable. A pilot phase with 15 middle-aged and six older adults suggests that CH.CO40+ attracts, and may be particularly suitable for, subjective memory complainers. Implications of the pilot data for the further development of the intervention are discussed.
