The aim of this research is to optimize the selection of the sites of Evaporation
Tanks/Ponds, of Olive Mill Waste Water (OMWW). We have to achieve strict
environmental conditions, which in turn relate to a wide range of factors including
topograp
hy, namely: elevations, rivers, silos, lakes and faults, in addition of those related
to man-made geographical elements: cities, villages, roads, dams, wells and contemporary.
To complete the study and obtain reliable results, we adopt GIS, which requires defining
all of the above factors in the form of a graphical and descriptive environment.
The choice of potential sites is through verification of the required conditions using GIS.
This requires the availability of data specific to each condition, verification of other
conditions through field visits and measurements in the absence of necessary data, and it is
necessary to use the available space images significantly through GOOGLE EARTH for
initial verification of selected sites.
Appropriate technology is used according to the state of the OMWW, and according to the
economic potential of the application of this technology. The main objective of these
treatments is to reduce their load of organic matter. The remaining water will be used to
irrigate the agricultural land. Production of manure and feed of cattle.
This research aims to decrease the cost of last production stages
through decreasing the cost of potential casing repair by avoiding the
problems that casing string may be exposed to. Such problems are
caused by the temperature effect of salt dril
ling fluids as well as other
fluids normally existed in the annular behind casing at the nonecemented
intervals.
In this research we studied tricone drill bits by applying a
mathematical model which gives an analysis the effected factors on
its performance and efficiency(rate of penetration) , so we can
change these factors in valid allowable rang of operati
ng once ,
which it gives a positive impact on its performance which shorten
time and cost of drilling run , that has been in one of the Syrian oil
fields :Deir Ezzour petroleum company ..
This research aims to increase the production lifetime of oil and gas
wells through avoiding the problems that production casing string
may be exposed to. Such problems are caused by the effect of different
drilling fluids as well as other fluids normally existed in the annular
behind casing at the none-cemented intervals.
In this article we studied two types of teeth, spherical and
conical one. We compared the results with a previous study for the
flat tooth. the study of stresses field under these three teeth show
that in the soft rocks we prefer to use conical to
oth because it is
easy to be Implanted in the rock, and this was confirmed by the
values of stresses under the tooth. Either in hard rock and due to
our need for big values of pressure to shatter the rock we prefer to
use spherical tooth because of its property of forming tow cons of
stresses under tooth and therefore can be good in drilling hard
rock..
Basalt is classified as a isotropic rock in according to its mechanical
properties. But gypsum is considered isotropic transverse rock . coming
the mechanical parameters values joins practice direction of parameters
.
By using a nondestructive me
thod such as the ultrasonic test which
depends on understanding the effectual of mechanical properties upon
speed of ultrasonics inside rocks , one can indirectly predict the
mentioned parameters
Tests were completed within 35 gypsum and 11 basalt rocks specimens
which collected by completions under the direction of General
Organization for Land Development ( Directorate of Geological
Investigation).
In this research, we focus on the swelling properties of clay, the cation
exchange capacity and the efficacy content of clay in mud, to deal
ideally the drilling problems attached to clay formations in Syrian oil
and gas fields.
We have
provided in this paper an attempt to study the deformation of oil
wellbore using modeling because of its capability to analyze the
different hypotheses which give us a vision of what is happening
or could happen . We have built a model of
the phenomenon being
studied are expressed in a horizontal section of the oil well on the
geological layer , after loading forces and stresses, we analyzed the
results ( deformations ) for the sandstone ( elastic rock ) and clay
(plastic rock ), where it is shown- by making a hypothesis fit with
abnormalities in the state of the stresses in the oil fields - that the
anomalies in the state of stresses of principles geological stresses
plays an important role in the deformation of oil wellbore.
"Korashina Anhdrite" formation in the Syrian Central Region's wells
considered as covering for "Korashina Dolimite" formation which is
a gas bearing reservoir, and consists of a succession of salt, clay,
and Shale. Much of the problems faced durin
g drilling this strata
like (High over pull/drag values, high pumps pressure, drill string
stuck), which led in some cases to stop the drilling operation, and
thus an increase in the drilling time, resulting in high final cost for
the completion of the well, salt saturated water based drilling mud
used to drill this formation but it did not completely solve the
problems.
This research aims to find out drilling mud treated with some kinds
of polymers and salts to be used to drill this formation with the
least problems.
The research was conducted on 60 patients, checking in the Department of Obstetrics
and Gynecology at the Assad University Hospital in Latakia, complaining of infertility(an
initial or secondary) between2011-2013
A satisfactory detailed story of t
he couple was taken with extra focus on the clinical
symptoms of polycysticovary of the wife (obesity, hirsutism, irregular menstruation,
infertility) and overlooking other feminine or masculine causes of infertility. In addition to
the calibration of Fsh, Lh, free testosterone, and ultrasound imaging of the uterus and
ovaries,
a perforation was performed on the ovaries by laparoscopic surgery. Patients were
checked for a year. This check up showed healthy pregnancy in 27 patients by 45%, but
this didn't work for 31 patients by 51.66%. In addition, 2 cases of abortion3.33% were
reported. . The study showed that age, duration of infertility and the rate of LH had an
effect on the success of the laparoscopic ovarian drilling process with patients of
Polycystic ovary.
