ABSTRACT: -Formation damage canincurconsiderable cost for remediation and deferred production. Thorough understanding of the formation damage mechanisms, stringent measures for its control and prevention, and effective and efficient treatments are the keys for optimum production strategies for oil and gas fields. WELL 4X was investigated in this study to properly diagnosed and evaluate productivity in OREDO FIELD and Bottom Hole Pressure survey was used from Bottom Hole Pressure analysis in addition to the information of the well production history and reservoir data available to determine and assess the extent of the formation damage in the well. The WELL 4X was stimulated using Acid Foam Diversion Techniques to enhance reservoir productivity and increase economic operations. The stimulation job done on the well showed a peak increase of production from 850 bbl/day to 3200 b/d before it declined to 2150 bbl/day, and finally maintained an average stabilized rate of 2000 bbl/day. It has to be established that the treatment method on WELL 4X using Acid Foam Diversion Techniques and the Bottom Hole Pressure survey conducted on the WELL 4X in OREDO FIELD is found to be efficient in the determination and evaluation of formation damage. KEYWORDS: - (Bottom Hole Pressure, Formation Damage, Permeability, Stimulation, Well 4X) I. INTRODUCTION Producing formation damage is the impairment to reservoir (reduced productivity) caused by wellbore fluids used during drilling/completion and workover operations. It is a zone of reduced permeability within the vicinity of the wellbore (skin) as a result of alien-fluid invasion into the reservoir rock(Dake, 1978). This reduced production results in an indeterminate reduction of the efficient exploitation of hydrocarbon reservoirs. The situation is both undesirable economically and operationally, hence, it is considered as a difficult problem to the oil and gas industry(Leontaritis et al., 1994). As a result conducting an in-depth analysis of the producing formation to customize a fluid specific in OREDO FIELD that will help minimize formation damage and thus increase production rate is of paramount interest to the general economics of the field.As expressed by Amaefule et al., 1988, “Formation damage is an expensive headache to the oil and gas industry.” Bennion,1999 described formation damage as, “The impairment of the invisible, by the inevitable and uncontrollable, resulting in an indeterminate reduction of the unquantifiable!” Formation damage assessment, control, and remediation are among the most important issues to be resolved for efficient exploitation of hydrocarbon reservoirs (Civan, 2005).Formation damage does not occur naturally. It is caused by physio-chemical, chemical, biological, hydrodynamic and thermal interactions of porous formation, particles, and fluids and mechanical deformation of formation under stress and fluid shear. Fluids introduced into the formation during various operations carried out to bring a well on stream and also during the life of the well have the potential of reducing the well permeability and impairing productivity. Formation damage can occur due to any one of the following physical or chemical interaction between invading liquid phase and the reservoir rock constituents. This problem leads mainly to potential clay swelling, wettability alteration and potential water blocking.Formation damage indicators include permeability impairment, skin damage, and decrease of well performance. As stated by (Civan, 2000), “Formation damage is not necessarily reversible” and “What gets into porous media does not necessarily come out.” Beadie, 1995 called this phenomenon “the reverse funnel effect.” Therefore, it is better to avoid formation damage than to try to restore it. www.ajer.org Page 1 American Journal of Engineering Research (AJER) 2015 A verified formation damage model and carefully planned laboratory and field tests can provide scientific guidance and help develop strategies to avoid or minimize formation damage. Properly designed experimental and analytical techniques, and the modeling and simulation approaches can help understanding diagnosis,

Ehrlichiosis is a worldwide zoonosis illness and mostly occurs in tropical and subtropical regions that are close to the vector’s distribution. Tick-borne pathogens lead to over 100,000 cases of illness in the world each year. Besides the costs of the additional ve- terinary care, anaplasmosis causes abortion in animals, reduction of milk production, body weight, and frequently leads to death. In this study, we investigated on infection of ticks to Anaplasma and Ehrlichia pathogens in Zabol and Zahak County in Sistan and Baluchestan Province where is bor- dered with Afghanistan.

One of the most crucial issues in regional development is recognizing the spatial and economic structure of the region. In studying the economic structure of the regions, middle cities have an essential role after first class cities. Nowadays, in most developing countries the planners’ tendency toward spatial decentralization, reducing regional inequalities, etc. has led to adopting different urbanizing strategies. In this regard, the present research aims at analyzing and studying the role of Zabol city in regional development. This research adopts a descriptive-analytical approach based on library resources and field study and in order to analyze the data the AHP model is used. The results show that indicator C (reducing regional inequalities) with a weighted mean of 0.391 stands the first and indicator D (accommodating the population in the region) is placed the fourth with a weighted mean of 0.191. KEY WORDS: regional development, balance, Sistan, Zabol city I. INTRODUCTION The aim of regional studies is to regulate the relationship between human, space and activity or the suitable and moderate arrangement of human and his activities over the land (Ziari and Fallah Madvari, 2006).

Kord Kerman Branch, Islamic Azad University A. Payan ∗ Zahedan Branch, Islamic Azad University S. Saati North Tehran Branch, Islamic Azad University Abstract. The agricultural sector ensures food security in every coun- try. Optimal agricultural practices presuppose the optimal allocation of resources, including water, soil, etc., by official authorities in every country because excessive use of natural resources would have harmful consequences for posterity despite meeting ad hoc needs. Therefore, sustainable agricultural practices in different regions should be based on environmental, social, and economic criteria in the decision-making process for the future. This study investigated the agricultural prac- tices in two stages: environmental stage (planting and maintaining) and economic stage (harvesting), which use shared resources. A net- work DEA model was proposed for developing sustainable agricultural practices based on the proposed process. The development of sustain- able agricultural practices in different regions presupposes the optimal Received: February 2020 ; Accepted: December 2020 *Correspondingm author 1 2 A. KORD, A.

Zahedan. Iran; 2Hakim Ferdowsi of Farhangian University, karaj. Iran; 3Faculty Member and Director of Department of Geography of Tourism Planning in National University of Tajikistan. [email protected] Abstract: Understanding the concept of sustainable development and the value of natural, historical, and cultural heritage has been raised in the issue of tourism in most countries. Tourism is primarily considered the activities in leisure time, in which the tourist desirably spends his/her purchasing power from the source to the destination. In other words, tourism, from an economic perspective, is a kind of purchasing power transfer from the source to the destination. On the other hand, from a social and cultural view, tourism is an effective factor in cultural exchange and consolidation of human bonds that encourages the national coherence in various regions of a country through domestic tourism and international bonds by foreign tourists. Iran, due to its privileged geographical position which is situated at the intersection of economic and cultural exchanges between the East and the West of the world and given its rich civilization and cultural legacies (Iran is among the top ten countries in the world in this regard), can improve and consolidate its position in tourism industry. Sistan and Baluchestan Province is located in the extreme southeast of Iran and is the entrance and exit gate of Iran to the Indian subcontinent, South-East Asia, and the southern coasts of the Oman Sea (both through land and sea).
