ABSTRACT The Federal Government of Nigeria in a bid to promote indigenous companies participation in the oil and gas sector, and to grow the nation’s production capacity passed legislation in 1999 to foster the exploitation of Marginal Oil Fields (MOFs). MOF is one that is considered non – commercial as a result of strategic business development philosophy of the operator, often times large oil companies. Reservoir management is central to the effective exploitation of any hydrocarbon asset; this dependence is heightened for an undeveloped marginal field. There is no ‘one-size fits all’ approach to reservoir management; this paper reviews some techniques adopted by Midwestern Oil and Gas Ltd in the development of the Umusadege marginal field. These techniques fall under three categories: (I) subsurface study (II) well placement and spacing, (III) integrated surface production and optimization, in accordance with regulatory practices.  The previously acquired 3-D seismic data was reprocessed and interpretation of reservoir heterogeneities within the Umusadege field concessionary boundary carried out form the basis of the initial field development plan. To optimize reservoir drainage, the general principles of non-interference well spacing were employed, and advanced well placement technology was deployed to guarantee optimum well placement within the reservoir for effective and efficient drainage. Subsequently, 14 vertical wells and 4 horizontal wells were drilled to effectively optimize recovery from the field. Prior to bringing these wells on-stream, clean-up and Maximum Efficiency Rate (MER) tests were conducted to determine the optimum choke settings, GOR and water cut limits for all wells. An integrated approach encompassing choke sizing, gas and water production management, vessel and line sizing were implemented on the Umusadege field to maintain and optimize recovery. Crude custody transfer measurements and export were enabled by an optimized Group Gathering Facility (GGF).The above techniques combining new technologies, traditional reservoir and production strategies led to the successful development of the Umusadege field; increasing daily oil production from 2,000 bbls/d from the first well re-entry to approximately 30,000 bbls/day over a 7-year period. This case study proves that with the correct implementation of the key elements of reservoir management the value of any hydrocarbon asset can be maximized in a cost effective, safe and environmentally friendly manner.

Management Issues

In the recent years, the growing demand for energy on the one hand and the reduction of conventional hydrocarbon reserves on the other hand have made the proper extraction of oil and gas reserves, i.e. reservoir management issues, more important and hence proper management of these reserves is inevitable. Although renewable energies currently provide the bulk of the world’s energy needs, hydrocarbon fuels remain the main source of energy until 2035.Despite the growing importance of the Integrated Reservoir Management Model (IRMI), as a rational solution to maximize economic production from oil and gas reservoirs, a comprehensive model that can cover all reservoir management modules has not yet been proposed. In this paper, by examining the current condition of reservoir management in one of the subsidiaries of the National Iranian Oil company and analyzing the obtained results, we offer some solutions to improve the condition and finally, we present a comprehensive model for reservoir management in this company.

Operation And Management

As the subject of oil and gas production, reservoir management is the oil production plant’s core business. But at present, there are some problems in reservoir management. For example: the development and management unit is not clear; the organizational structure is not streamlining; management mechanism is not perfect; evaluation is not systematic and so on. So, the oil production plant should focus on those four aspects to explore reservoir management---“unified the ground and underground, clear the input-output” “flattened the management layers, specialized functions structure” “market-oriented economy development, optimize the production process” “long-efficiency business goal , comprehensive evaluation of analysis”

Abstract The proper exploitation for a gas condensate reservoir requires an integrated collaboration and management strategy capable to provide detailed insight about future behavior of the reservoir. When a development plan is generated for a field, the reservoir management is not performed integrally, this is, different domains: geology, reservoir, drilling, production, economics, etc., work separately, and therefore, an adequate understanding of the main challenges, leading to issues such as an over dimensioning of surface facilities, excessive costs, among others. Through this paper, a methodology to improve the conventional field development plan is described, which contains 4 main pillars: Collaborative approach, Integrated analysis, engineering optimization and monitoring & surveillance. The methodology involves the description of a hybrid workflow based on the integration of multiple domains, technologies and recommendations to consider all the phenomena and compositional changes over time in the whole production system, aiming to define the optimum reservoir management strategy, facilities and operational philosophy as part of the Field Development Plan (FDP). Conventionally, the used of simplistic models most of times do not allow seeing phenomena in the adequate resolution (near wellbore and porous media effects, multiphase flow in pipelines, etc.), that occur with high interdependency in the Integrated Production System. With this methodology, the goal pursued is to support oil and gas companies to increase the recovery factor of gas condensate fields through the enhancement in the development and exploitation process and therefore, reducing associated costs and seizing available time and resources.
