Authors: Manchikanti Dinesh , Aggarwal Manisha , Thomas Shaji , Arsia Ashish , Pusuluri Rahul , Kumar Sanjay 
Published: October 2021

Trichobezoar is a rare clinical entity in which a ball of hair accumulates within the alimentary tract. When the tail of the trichobezoar extends into the small intestine, this condition is called Rapunzel syndrome (RS). A 14-year-old female presented with pain abdomen and vomiting for 2 weeks, and a history of trichotillomania and trichophagia, and an epigastric lump. A contrast enhanced computerized tomography (CECT) of the abdomen showed a grossly distended stomach with a heterogeneous mass containing trapped air with underlying normal mucosa suggestive of trichobezoar, with its tail extending into the proximal jejunum suggestive of RS. During laparotomy, a giant trichobezoar was seen in the stomach with its tail extending beyond the duodenum into the proximal jejunum. The entire specimen was delivered out intact. On follow up, she has no surgical complications, and was on behaviour therapy. Trichobezoars form when ingested hair strands become retained in the folds of the gastric mucosa and becomes entangled, forming a ball too large to exit the stomach. Trichotillomania and trichophagia are seen in many of these patients. Patients present with abdominal pain, vomiting, gastric outlet obstruction, and an epigastric mass. In the case of RS, complete removal without breakage and distal migration is important. RS should be considered as a differential diagnosis in a young girl with abdominal pain, vomiting, anaemia and upper abdominal lump. Early diagnosis prevents complications. Surgical removal is treatment of choice. Trichobezoar often coexists with psychiatric illness. Psychiatric evaluation, counselling and treatment are helpful in preventing recurrence.

Authors: Figueiredo Santos José Alcides 
Published: October 2021

O trabalho investiga as relações entre origem e destino de classe social no Brasil com o uso do suplemento de mobilidade social da Pesquisa Nacional por Amostra Domicílio (PNAD) 2014. Os efeitos da origem social foram estimados sob a forma de probabilidades preditas na média dos casos de o filho estar no topo social.A estratégia de investigação e o esquema de classe empregado são algo novo no âmbito dos estudos de mobilidade social no país. A magnitude constatada e a evolução dos efeitos totais e diretos da origem privilegiada colocam em questão o papel equalizador da educação. A origem no topo social tanto incrementa o efeito da escolaridade superior quanto favorece quem fracassa na escola. Os retornos absolutos da escolaridade superior estão caindo. A origem no topo social não é afetada por este processo. Grupos abaixo do topo estão contribuindo para a tendência declinante. No acesso ao topo social, vantagem de origem continua a gerar vantagem de destino no Brasil.

Seeking Low Relief Structures: An Original Approach Applied in Western Oman
Authors: Benkara-Mostefa Cherif , Saint-André Cyril , de Bazelaire Eric , Girard Marc 
Published: October 2021

ABSTRACT
A multiple elimination technique was tested in Elf’s Butabul Concession in Western Oman. The multiples mask the main exploration target, the Permian-Carboniferous Haushi reservoir. The technique is based on inversion in a curvature-time domain. The common mid-point gathers are transformed into this new domain and a mute is then applied to eliminate the multiples. The resulting function is then transformed back to the space-time (x-t) domain. The technique was tested on a newly-acquired, high-resolution seismic line. The survey is approximately 100 kilometers and traverses a low relief seismic prospect south of the Rabkha-1 well. Special high-resolution field acquisition parameters were used to maximize the effective separation of real events from multiples. To prevent aliasing the source and trace spacing were 12.5 and 25 meters, respectively. The Rabkha-1 well was used to select the best mute in the curvature-time domain. The mute required only minor adjustments over the line. The technique proved effective in eliminating the multiples and the resulting interpretation convinced the explorationists not to drill the prospect.
Jurassic Geology of Kuwait
Authors: Yousif Samir , Nouman Ghalib 
Published: October 2021

ABSTRACT
Until the late 1970s only one well penetrated the entire Jurassic section of Kuwait. A few other scattered wells partially penetrated it. During the 1980s an appreciable number of deep wells revealed that the Jurassic sequence is inverted with respect to the Cretaceous sequence and that the main Cretaceous arches were sites of Jurassic sedimentary troughs. This new interpretation marks a revolution in the existing concepts for Jurassic oil exploration in Kuwait. One of the most effective methods for defining of Jurassic structures is the isopach of the Upper Jurassic Gotnia Formation. The main Jurassic reservoirs include the Najmah, Sargelu and Marrat formations which were detected as a result of the exploration activities during the 1980s. Selective stratigraphic and structural cross-sections reveal the stratigraphic relationships of the Jurassic sediments.
Lithostratigraphy, Sedimentology and Hydrocarbon Habitat of the Pre-Cenomanian Nubian Sandstone in the Gulf of Suez Oil Province, Egypt
Authors: Alsharhan Abdulrahman S. , Salah Mohammed G. 
Published: October 2021

ABSTRACT
The Paleozoic-Lower Cretaceous Nubian Sandstone is a thick sequence of up to 1,200 meters of clastic and thin carbonate sediments. In ascending order it is classified into the following groups and formations: Qebliat Group, Umm Bogma Formation, Ataqa Group and El-Tih Group. This sequence is composed mainly of sandstones with shale and minor carbonate interbeds and was deposited in continental and fluviomarine to marine settings. Petrographically, two main facies of Nubian Sandstone can be recognized in the Gulf of Suez: quartzarenite and quartzwackes. Both contain subfacies that are different in their secondary components, cement and matrix types, reflecting their different depositional environments and diagenetic histories. The pre-Cenomanian Nubian Sandstone is one of the most prolific reservoirs in the Gulf of Suez oil province. These sandstones have intervals with good reservoir quality throughout the basin, with net pay thickness of up to 450 meters, and net sand ratios ranging from 60% to 90%. Porosity varies from 10% to 29%, and permeability from 70-850 millidarcies. The quality of the reservoir depends on its shaliness, diagenetic history and the depth of burial (compaction). The Nubian Sandstone still has a high potential as a reservoir, particularly in the northern sector of the Gulf of Suez where few wells have specifically targeted this interval.
Stratigraphy of the Lower Paleozoic Haima Supergroup of Oman
Authors: Droste Henk H.J. 
Published: October 2021

ABSTRACT
Following the discovery of significant gas/condensate reserves in Lower Paleozoic clastics in Central Oman a regional geological review using all available well data and a set of regional seismic lines was carried out by Petroleum Development Oman. The objective of this study was to support further appraisal and exploration activities. A chronostratigraphic framework of regional correlatable major flooding surfaces improved the understanding of the stratigraphic relationship between the different units and the regional distribution of the reservoir seal pairs. The interval of interest, the Cambrian to Lower Silurian Haima Supergroup, is a late syn- to post-rift siliciclastic infill of an extensive graben system. The depositional setting was initially continental but higher in the sequence of marine deltaic setting prevailed. The sequence is characterised by the occurrence of laterally extensive sand sheets typical of pre-vegetational times but difficult to interpret sedimentologically. At least six major transgressive regressive cycles can be recognised which can be regionally correlated. Marine intercalations are limited to Central and North Oman. The clastic influx into the grabens was initially of local origin but as the grabens filled up the sediments were predominantly derived from a southern source.
Structural and Stratigraphical Setting of the Faiyah Range, Northwestern Oman Mountain Front, United Arab Emirates
Authors: Noweir M. Atef , Alsharhan Abdulrahman S. , Boukhary Mohamed A. 
Published: October 2021

ABSTRACTThe Faiyah Range belongs to a group of regional ridges that formed by post-obduction folding of the Upper Cretaceous-Tertiary sedimentary rocks exposed along the western margin of the Northern Oman Mountains. The Faiyah Anticline, generally trends north-northeast to south-southwest with thrust faults striking parallel to the fold axis. The anticlinal hinge was later displaced by a dextral strike-slip fault, named here as the Faiyah Fault, into two segments. The northeastern segment includes Jebels Rumaylah, Faiyah and Mulayhah, and the southwestern segment includes Jebels Buhays and Aqabah. The anticline is interpreted to result from northeast-southwest compression during the Tertiary.In the Faiyah Range the neoautochthonous sedimentary rocks are the Maastrichtian Qahlah and Simsima formations, and the Eocene Dammam Formation. Stratigraphic evidence shows that the lower part of the Qahlah was deposited in a non-marine environment while the upper part was deposited during a marine transgression. The Simsima was deposited in a shallow-marine environment. These units unconformably overlap the allochthonous Semail Ophiolite. The microfaunal content of the so-called Muthaymimah Formation (?Tertiary), of earlier authors, indicates that it is of Maastrichtian age in the Faiyah Range. This sequence is also conformable to the Simsima and therefore it is considered to be the upper member of the Simsima in this area.
Regional Structural Style of the Central and Southern Oman Mountains: Jebel Akhdar, Saih Hatat, and the Northern Ghaba Basin
Authors: Mount Van S. , Crawford Roderick I.S. , Bergman Steven C. 
Published: October 2021

ABSTRACT
Three quantitative regional transects across the Saih Hatat and Jebel Akhdar anticlines in the Central and Southern Oman Mountains and the Northern Ghaba Basin have been constructed based on surface, well and seismic data. Interpreted large-scale structural geometries suggest that the Saih Hatat and Jebel Akhdar anticlines are basement-involved compressional structures, underlain by north-dipping, high-angle, blind, reverse faults located beneath their southern limbs. A compressional deformation event initiated in the Oligocene (constrained by apatite fission track data) involving the high-angle reverse faults is interpreted in which pre-Permian strata and Permian-through-Lower Cretaceous strata, exposed in the Saih Hatat and Jebel Akhdar anticlines, were parautochthonous - uplifted over the underlying reverse faults, and not displaced a great distance laterally. The allochthonous Hawasina and Sumeini sedimentary rocks and the Semail Ophiolite complex are interpreted to have been emplaced onto the carbonate platform during the Late Cretaceous, and have subsequently been parautochthonous during the Tertiary deformation.
The upper portion of the pre-Permian section in the Ghaba Basin consists predominantly of a thick (&gt;4 kilometers) sequence of Cambrian-through-Silurian, predominantly non-marine to shallow-marine, clastics of the Haima Supergroup. In contrast, out of the Ghaba Basin proper in the Central Platform or Musallim High region, the Haima Supergroup is generally less than 2 kilometers thick, and interpreted to thin to the north. The fundamental difference in pre-Permian strata exposed in the Saih Hatat and Jebel Akhdar Anticline windows is the thick (&gt;3.4 kilometers) section of Ordovician age, shallow-marine strata (Amdeh Formation) present in the Saih Hatat Anticline, but absent in the Jebel Akhdar Anticline. In our interpretation, the shallow-marine clastics exposed in the Saih Hatat Anticline represent the northern extension of the Early Paleozoic Ghaba Basin, which have been uplifted over a high-angle reverse fault in the Early Tertiary deformation event. The cross-section through Jebel Akhdar is located to the northwest of the Ghaba Salt Basin, along the Musallim High. In this area the thickness of the Ordovician strata deposited is interpreted to be less than in the Ghaba Basin. The Ordovician section is not present in the Jebel Akhdar structure - the thinned section likely eroded in a Late Paleozoic deformation event.
Plio-Quaternary Movement of the East Arabian Block
Authors: Weijermars Ruud 
Published: October 2021

ABSTRACTNew data presented herein support the previously suggested existence of an East Arabian Tectonic Block in Saudi Arabia. However, the East Arabian Tectonic Block is not exclusively bound by grabens, as was previously thought, but also by strike-slip faults and transpressive folds (in what is named here the Mughrah-Al-Kharj Transpression Zone), which laterally grade into the transtensive Central Arabian Graben System. Evidence for Plio-Quaternary strike-slip motion is presented here for the first time and supports previous contentions that graben formation occurred in Plio-Quaternary time. These new observations allow the development of a tectonic model that succinctly explains the deformation along the margins of the East Arabian Block.With the importance of regional fault structures thus recognized, even some major faults of tectonic dimensions start to emerge in the Eastern Province of Saudi Arabia. For example, radar images from the Space Shuttle Endeavour confirm that the Nisah Fault extends eastward along Wadi As-Sahba, over a total distance of 250 kilometers, which was previously undemonstrable. The Sahba Fault is made visible beneath the Ad-Dahna Sand Sea by virtue of the sand-penetrating capability of the L-band radar. Five to eight kilometers of left-lateral strike separation is visible on either side of Wadi As-Sahba which truncates the southern end of the Ghawar field. The graben structure of the Nisah Fault System had been reported before, but its eastward continuation and any strike separation were not established until now. Furthermore, the Nisah-Sahba Fault System may extend further eastward, beneath alluvial gravels, for an additional 200 kilometers to join a known lineament at the southern end of Qatar. Further extension towards the Gulf into the 600-kilometer long Trans-Arabian Gulf Fault is also suggested here for the first time.Field evidence presented here indicates that a substantial part of the motion of the Central Arabian Graben System took place in the Plio-Quaternary and may continue at present. This has been inferred from a study of the wadi (flood valley) system on the Jubaila and Hanifa outcrops in the vicinity of the graben structures to the south of Riyadh. In fact, an 8-kilometer long section of a mature stream channel, known as Sha’ib al-Miklaf, which was formerly discharging intermittent wadi drift and torrential run-off waters into Wadi Hanifa, has now been cut off from its former catchment area by the graben tectonics. As a result Sha’ib al-Miklaf now lies idle between the active wadis of the Awsat Graben and the Nisah Graben. The occurrence of recent fault motion in the Arabian Platform is further supported by changes in thickness of the Ad-Dahna Sand Sea across the Sahba Fault, as well as by truncation of mega-barchanoids in the Jafurah Sand Sea across the Jaub lineament. Not surprisingly, some modern seismicity in the Eastern Province of Saudi Arabia may be attributed to motion on the Nisah-Sahba Fault System.
A New Look at the Middle to Lower Cretaceous Stratigraphy, Offshore Kuwait
Authors: Al-Fares Abdul Aziz , Bouman Mark , Jeans Pete 
Published: October 2021

ABSTRACT
Offshore exploration in Kuwait commenced in 1961 with the award of a 5,600 square kilometre offshore concession to Shell. Some 6,300 kilometres of 3-fold analogue seismic were acquired in 1961, and 3 wells were drilled during 1962 and 1963. In the same period, Kuwait Oil Company (KOC) also drilled their first 3 offshore exploration wells. In 1981, KOC embarked upon a second offshore exploration campaign, acquiring some 6,000 kilometres of seismic data and, during 1983 and 1984, drilling two wells. None of these wells was a commercial discovery.
Between 1995 and 1997, an integrated team of KOC and Shell explorers undertook a review of the hydrocarbon potential of Offshore Kuwait. In order to establish an integrated sequence-stratigraphical framework for the prospective Lower to Middle Cretaceous interval, a quantitative biostratigraphical study was made. Some 790 biostratigraphical analyses (10% core samples; 90% cuttings) from eleven wells were carried out: the nanno-fossil data was particularly important in providing accurate chronostratigraphical calibration, and this data has been used to constrain a “Time-Rock Synopsis”.
KOC’s lithostratigraphical nomenclature proved to be basically sound and has been maintained as the basis for the present stratigraphical framework. However, the study revealed the existence of two substantial and hitherto unsuspected hiati: one between the Ratawi and Zubair formations of Early Valanginian to Mid-Hauterivian age; and the other, representing the whole of the Early Albian, within the Burgan Formation. This latter result, if it can be further substantiated by more exhaustive study in the onshore area, would neccessitate a re-definition of the Burgan Formation and the erection of a new formation to describe the clastic sequence of Late Aptian age which lies between the Early Albian hiatus and the top of the Shu’aiba Formation, and which has hitherto been included within the Lower Burgan Formation.
Tectonic Evolution of Northeast Syria: Regional Implications and Hydrocarbon Prospects
Authors: Brew Graham , Litak Robert , Barazangi Muawia , Sawaf Tarif 
Published: October 2021

ABSTRACT
We present the Phanerozoic tectonic evolution of northeast Syria and incorporate the results into regional deformation models of the northern Arabian Platform and nearby Arabian Plate boundaries. Based on analysis of extensive seismic reflection profiles and well data, we interpret that the Sinjar-Abd el Aziz area in northeast Syria was subsiding under extension at various rates from the Carboniferous until the end of the Mesozoic, most markedly during the latest Cretaceous. The predominant basin through most of the Late Paleozoic and Mesozoic was southwest-northeast trending; this formed the northeast extension of the major Palmyride Basin to the southwest. During the Late Cretaceous, extension in eastern Syria initiated along southeast-northwest and then east-west trends - possibly as a result of changing subduction geometries and plate motions in the Neo-Tethys to the northeast. The east-west striking faulting resulted in syntectonic deposition of up to approximately 1,600 meters of Late Campanian-Maastrichtian marly limestones in the Sinjar-Abd el Aziz area. The area was subjected to horizontal shortening throughout the Cenozoic, primarily during Plio-Pleistocene time, resulting in structural inversion along some of the faults. Although crustal shortening through the Syrian Sinjar and Abd el Aziz structures is relatively minor (approximately 1%), this has been critical to hydrocarbon trap formation in Mesozoic and Cenozoic strata through the formation of fault-propagation folds. We present regional models that show the interrelated tectonic history of northeast Syria, the Palmyrides, and the Euphrates Fault System are all inseparably linked to the polyphase opening and closing of the nearby Neo-Tethys Ocean.
