    Opis:
    Generally, the mature fields have a good portion of the remaining reserves still trapped due to inefficient drainage, pressure decline, inerease in water cut, sand production and aging of the existing system. This paper addresses a methodology applied on the historical produetion behavior to identify techniques and initiatives to optimize the recovery factor based on redevelopment plans in a mature field. For Laslau Mare field in particular, there have been identified and implemented opportunities such as: infill drilling, work over optimization, dynamie underbalance perforation (DUP), acidizing, kick off with N2, propellant stimulation, snubbing, soaping, sand management, Wavefront Technology stimulation and wellhead and/or group compressor installation.

    Opis:
    The mature gas fields rehabilitation represents a permanent concern of the Romgaz technical management, being considered one of the major priority of the development strategy of our company. The most part of our gas fields located in the geological unit of Transylvanian Basin are characterized by an advanced stage of exploitation, with a long production history and high cumulatives, having a current recovery factors of more than 60-70%. This status gives them the name "mature fields", or "brownfields" concepts logically associated with another notion, called "rehabilitation", also very frequently used in the world oil and gas industry. As the production decreasing became actually more obviously, due to the natural energetic decline of the reservoirs, the only viable solution to overcome this, consists in finding technical, commercial and operational best practices designed to develop incremental production and access additional reserves. This issue has preoccupied also the Romgaz technical team to implement and develop in the same time a new management strategy of this type of reservoirs, setting up a special department for designing the rehabilitation projects for our mature gas fields.

    production life cycle
    Opis:
    Mature gas fields are subject to network backpressure fluctuation causing liquid loading condition. The liquid loading, theoretically, occurs when the gas velocity is below its critical velocity which commonly happens in mature fields when rates become “low”. Based on Turner or Coleman’s equations, the critical velocity is proportional to the wellhead flowing pressure. This means, when the wellhead pressure increases as the result of higher external (sales) pressure, then the critical velocity will be higher. This condition will give a “pseudo” production decline of the wells. Gas compression is among the best fit-for-purpose solution to overcome the above challenges. Gas compression will help to reduce the wellhead flowing pressure which increases the gas velocity above the critical velocity as well as the well gas rate by lowering the bottomhole flowing pressure. The wells will be capable of unloading the liquid inside the wellbore and the reservoir will suffer a higher pressure drawdown. Moreover, the wells will not be impacted by the external pressure fluctuation as long as this latter is below the compressor discharge pressure. Gas compression has been implemented in Laslau Mare mature gas field to extend the production life cycle. 5 wellhead compressors have been installed since 2010 and 1 group compressor since 2014. Both types of compressor show positive results. This paper explains the application of compressor in Laslau Mare field starting with candidate selection up to cash flow analysis. A big emphasis will be given to the compressor/ well performance.

    Opis:
    Since the concept of Smart Field emerged, the operating companies work hard to enable such capabilities through various technology developments, both in the field and the office. Smart Fields help to manage, deliver, optimize and develop short and long term decisions and plans. The technology of “Smart Fields” is based on the measurement of process parameters in the reservoir and on the surface [4]. Implementing Smart Gas Field help us to maximize the value of production and increase profitability, while reducing operating costs and the use of industrial services. The integrated and automated data from sensors, simulated models and controllers provide reliable diagnostic tests, enable measurable improvements and implement a favorable environment to plan and schedule phases of production [5]. The main challenge for Romgaz was to combine and integrate older system into newer one. The problem was the installed old technology equipment, which was difficult to replace by the new one. During the last years in the most majors fields has begun a process of rehabilitation. To extend the mature gas reservoir life we redeveloped and optimized the fields, improving productivity and reservoir performance. To aim these goals, today, we need monitoring / surveillance programs for optimizing the production . It is important to measure the parameters of process conditions as accurately as possible.
