No one can deny the expanded role of oil in Iran and world’s economy. Exploration or development hydro carbonic reservoir and studying their situation is very important. This issue can be done by the help of Iranian professional’s knowledge and skills and reliance on more than 100 years Iran’s oil industry experience and different equipment and methods.
Well-Logging is a series of methods which gives continuous information of different characteristics of reservoir. In logging operation by help of different updated methods and equipment, some information of physical nature of reservoir rock such as porosity, permeability, rock type and also way of fluid saturation inside it will be gained. Information gained from this operation is called log or reservoir evaluation charts which lead reservoir engineers and operation on correct and better production from oil and gas reservoirs. Well logging has a very important role in oil industry and because of valuable information it gives, is named as the eye of the industry. The information in result of logging will be the basis of massive investment and planning in improvement and maintenance of oil and gas fields. According to this growing importance, different tools and methods in this field has been created and improved. Specially by improving the human sciences, using the electronic and communicative technologies in the fields of Well-Logging das been improved.
Logging industry in Iran despite its importance and position in exploration and development of hydro carbonic has been ignored till now because of lack of proper investment in this industry. In the following we mention to some of challenges logging industry faces.
Localization of logging industry, opportunity or threat?
Logging in oil industry has begun in 1927 and till now because of political situation of the country has suffered lots of ups and downs. Since 1927 that schlumberger presented the first logging services, according to that time’s science simple tools were used to give us primary results. Nowadays this system’s technology in the world has gained new tools which give us valuable information from unknown angels of reservoirs. In the sanction period lack of updated equipment had the most strokes to the country logging field. Because not only there was no access to updated equipment, but also by using copied and non-standard equipment, the very low quality information gained from oil and gas reservoirs, which in some cases suffered lots of damages and expenses in field development procedures to oil industry.
Over more than 110 years of country oil industry in spite multiple threats, no proper opportunity has been made. One of the proper methods of solving this problem is localization of logging equipment by reliance on updated science of Iranian committed specialists. Unfortunately Despite the existence of this potential, the share of manufacturing logging equipment in comparison with other branches of oil industry is still very low. (Less than 10 %). This issue is because of lack of attention of authorities, not having a special trustee, lack of assigning proper budget and invests no connection between industry and university, not supporting private companies, and using courage and punishes special methods and other factors. Honorable authorities have to pay attention to the point that the valuable information of country reservoir should have a high degree of importance and security and should not be the test area for foreigners ‘equipment because of lack of attention. According to existing enough science in the country and commitment and expertise of the country’s industrialists and due to its special importance, it is necessary for the authorities to localize the logging equipment of oil industry.
On the contrary of logging section, Lattice work section has been improved 90% by efforts of specialists and experts of defense industry and private section in constructing Lattice work balls with higher quality in comparison with foreign products. And we have to appreciate all localizers in this section.
Absence of comprehensive information bank of logging companies
At the present regarding to absence of local technology in logging field, every governmental or private companies by buying or renting a special technology from logging equipment suppliers (European/ Chinese) are giving logging services. Whereas the operation of these equipment has not been evaluated in the operating situation of rigged wells in Iran’s oil and gas fields, so this issue caused these wells become their TEST WELLS and in addition to imposition operational risks, it has hard damages to fields’ necessity information. On the other hand, every operator company by not having a comprehensive record of these tools’ operation in turn according to existing received documents of logging companies applies the evaluation/reception or not reception of logging companies in its tenders. And this is in the way that logging companies apply themselves exaggeration of their positive activities and hiding their inappropriate activities. In this situation the absence of a comprehensive information bank which registers the history of logging companies’ activities in level of National Oil Company will be appeared.
Existing of this information bank can be responsive to the vague activity points of these companies and causes necessity clearness in history of logging companies and makes the operator to have the best choice. In case of existing a logging contractors’ evaluation center in the level of National Oil Company as “Approved Contractor List” and announcing their operation history in an comprehensive information bank (until completion of equipment localizing) it can be very helpful.
