The correct study of the reservoir leads us to develop drilling
programs suitable for producing stratum.
In addition, this makes us do successful operations to achieve the
best recover factor ,within the convenient time and at the lowest
appropri
ate cost. This study will help us to avoid or solve many of
the problems associated with the production processes and the
most important problem of rehydration .In this research I did a
geological and reservoir study of the Jido Field which is one of
the fields of the Euphrates Company and it is located within the
area of graben Euphrates in Deir Azure to the east of Syria,
where recoverable reserves which are estimated in this field is
about 83 million barrels. The objective of the study was to know
the specifications and behavior of the reservoir and fluid inside
and the possibility of a Hydrodynamic connection between blocks
,where this information is taken into account when calculating
recoverable reserves and the assign of technological indicators for
investment.
The substance, Na٢-EDTA, disodium salt of Ethylene Diamine Tetra Acetic
acid, has big influence on the setting time of both Portland cement, and clinker.
The time of initial, and final setting is remarkably changed in the presence of a
small perce
ntage of Na٢-EDTA (less than ١٪ of the cement weight).
The chemical analysis indicates that the total concentration of calcium in the
aqueous phase of cement increases in the presence of Na٢-EDTA. While, the
concentration of free calcium ions in the aqueous phase decreases as the
percentage of Na٢-EDTA increases. Na٢-EDTA forms chelating complexes with
calcium, and some other metals such as iron and magnesium at high PH values,
as in the case of a mixture of cement and water.
