This fee is floating calculated with objective of motivating and supporting utilization of advance methods in exploration, development, production and operation customized to circumstances and specifications of each project, depending upon criteria such as potential production output of each oilfield or reservoir and respecting risk rate in exploration areas; and this fee is calculated proportional to international prices of oil and gas condensates as well as regional and contractual prices of gas in cash or in kind and would be paid based on the day price from commencement date of early production until end of term of contract. This fee is the main basis for selecting the successful bidder.

Note 1- All of the following are determined by Ministry of Petroleum and announced in tender documents: risk rate in exploration areas including land or sea areas, oilfield or reservoir size, deep or shallow waters and generally areas with low, medium and high risk along with specific risk rate of EOR/IOR from reservoir.

Note 2- With respect to the fact that all risks in exploration contracts (first category) are borne by the second party and in case of failure in exploring commercial oilfield or reservoir, expenses are not reimbursed. Assignment of another exploration block to the second party under the same terms and conditions can be stipulated in the contract in case of failure in exploring commercial oilfield or reservoir.

C- Fee for production of each oil barrel from oilfield or reservoir or each thousand cubic meter of gas or each barrel of gas condensates from gas reservoirs and reimbursement of direct, indirect and operating costs as well as related financing costs would be paid from maximum 50% of field products resulting from contract including crude oil, natural gas, gas condensates and other products and its revenue based on price on product sale date after achieving early production according to the contract. End of term of contract does not affect [stop] reimbursement of costs due, under terms and conditions stipulated in the contract.

Note- In case products of natural gas field are consumed in domestic market or they cannot be exported, NIOC may reimburse costs and fee from oilfield products and revenue, in order to reimburse costs and fee.

Article 7- In contracts subject to this act, Ministry of Petroleum may consider term of contract (contract duration) according to time required for implementation of projects and maximum for  20 years from commencement date of development activities. In case of implementing IOR/EOR, this duration can be extended up to 5 years according to operational and financial requirements of the projects. With regard to continuous exploration, development and operation projects, exploration stage period would be added to the term of contract.

Article 8- Payment method in order to achieve contract objectives is as follows:

A. Cost of exploration or appraisal activities would be defined and determined by invoking to principle of minimum exploration or appraisal obligation through the selection process of second party.

B- Cost and scope of exploration or appraisal, development and operation activities would be determined and agreed upon by both parties based on the approved annual work program and budget in order to achieve final objectives of the project according to reservoir conditions and its actual recovery.

C- In each contract, second party carries out its activities within the framework of procedures attached to the contract.

D- In each contract, a joint management committee is established that reviews all project activities and it makes final technical, financial and legal decisions within the contract framework, as well as decisions regarding assignment of subcontracts and also annual work program and budget. Second party to the contract has the responsibility of carrying out activities within the framework of the approved work program and budget. This committee is constituted of equal number of representatives from first and second party to the contract holding equal voting rights. Decisions of this committee are made unanimously and in case consensus is not reached, senior managers decide.

Implementation of these activities, within the framework of execution procedures attached to the contract, would be assigned to competent companies after approval of joint management committee. This type of contract in terms of its nature has no fixed cost ceiling at the signature date of the contract and this is an open capex contract and the amount initially noted is solely to estimate and predict the costs, actual costs are calculated in the project account according to work programs and budget which are approved based on reservoir actual recovery and market circumstances.

F- Implementation of all activities stipulated in the contract (except for management of whole contract and carrying out reservoir engineering studies) are assigned to competent contractors and manufacturers. Selection of these subcontractors would be made by contractor and approved by joint management committee according to the procedure attached.

Note- Reservoir engineering studies and costs resulting therefrom incurred by the second party would be acceptable and shall be calculated as direct costs in a manner that would be agreed under the contract.

Note:  with regard to Brown field/reservoir, if the first party deemed necessary implementation of activities with participation of one of its affiliates, and the Ministry of oil approves it, a joint operating agreement will be signed between the parties. These activities will be done jointly while responsibility of second party remains the same for technical, financial, legal and professional support and supervision, as well as providing equipment, tools and consumables.  The affiliated company shall in utilizing the facilities obey and implement all technical manuals and procedures of second party; otherwise the willful violation will be assumed as violation of contractual obligations by the first party.

It is also responsible, to propose modification plans-based on the experiences earned during its presence at the field- for maintaining the production capacity at the same level, improve or enhance oil recovery from field or reservoir. If the client approve these plans, the same methods, procedures and provisions of the main contract apply and while some modifications in cost calculation, contract schedule, the related fee are made, as well as, calculating the related costs stipulated in the annual work program and budget.
  3. During the operation, all and any investment and implementation of new plans at the contract area shall be approved by client and the operator shall operate all facilities handed over for operation, according to the provisions of this article utilizing the best international petroleum practices recognized by Ministry of oil.
  4. Oil, gas or gas condensate and any product produced as a result of production, entirely belongs to the Client.
  5. If any major repair or a re-entrance into the wells and their repair (work over) or any activity for maintenance of equipments and facilities is required, the activity would be carried out upon client’s approval and it would be reimbursed from the revenues generated from the incremental oil produced from the field or reservoir in addition to the financing costs in the amount agreed in the contract.
