The Impact

Summary This paper presents case studies focused on the interpretation and integration of seismic reservoir monitoring from several fields in conventional offshore and deepwater Niger Delta. The fields are characterized by different geological settings and development-maturity stages. We show different applications varying from qualitative to quantitative use of time-lapse (4D) seismic information. In the first case study, which is in shallow water, the field has specific reservoir-development challenges, simple geology, and is in phased development. On this field, 4D seismic, which was acquired several years ago, is characterized by poor seismic repeatability. Nevertheless, we show that because of improvements from seismic reprocessing, 4D seismic makes qualitative contributions to the ongoing field development. In the second case study, the field is characterized by complex geological settings. The 4D seismic is affected by overburden with strong lateral variations in velocity and steeply dipping structure (up to 40°). Prestack-depth-imaging (PSDM) 4D seismic is used in a more-qualitative manner to monitor gas injection, validate the geologic/reservoir models, optimize infill injector placement, and consequently, enhance field-development economics. The third case study presents a deep offshore field characterized by a complex depositional system for some reservoirs. In this example, good 4D-seismic repeatability (sum of source- and receiver-placement differences between surveys, dS+dR) is achieved, leading to an increased quantitative use of 4D monitoring for the assessment of sand/sand communication, mapping of oil/water (OWC) front, pressure evolution, and dynamic calibration of petro-elastic model (PEM), and also as a seismic-based production-logging tool. In addition, 4D seismic is used to update seismic interpretation, provide a better understanding of internal architecture of the reservoirs units, and, thereby, yield a more-robust reservoir model. The 4D seismic in this field is a key tool for field-development optimization and reservoir management. The last case study illustrates the need for seismic-feasibility studies to detect 4D responses related to production. In addition to assessing the impact of the field environment on the 4D- seismic signal, these studies also help in choosing the optimum seismic-survey type, design, and acquisition parameters. These studies would possibly lead to the adoption of new technologies such as broad-band streamer or nodes acquisition in the near future.

Intensive Use

The main problems for vegetable farmers are low technology and intensive use of pesticide, therefore farmers cannot produce vegetables with good quality continually. By applying agribusiness partnership it is expected the farmers would be able to overcome the limitation of technology and capital for small farmers attainment a good quality of vegetables, and problem of marketing. This study was aimed to analyze benefit involvement of farmers in agribusiness partnership. Collective case study method was used in five agribusiness companies and one co-operation which applying partnership of agribusiness in West Java: i.e. Bogor, Cianjur, Bandung, and Garut. The population are farmers around company and co-operation, the unit of analysis is farmers household counted of the 285 farmers. Involvement of farmers in partnership has effect on the improvement of farmers income, the use of technology (production and handling), appropriate pesticide use use, labor absorption, and capital usage. Involvement of farmers in partnership also has effect on continuity of farmers business.

With the theory and method of general system science, the paper, by taking Xianning City as a case study, established coupling coordination theoretical models of socio-economic benefits and eco-environmental benefits of urban land intensive use, then analyzed socio-economic benefits and eco-environment benefits of urban land intensive use, coupling degree and coupling coordinative degree between urban land intensive use socio-economic and eco-environmental by using the statistical data during 1999-2010. The results showed that: (1) The socio-economic benefits of urban land intensive use increased rapidly, however, the eco-environmental benefits of urban land intensive use increased in a fluctuation; (2) The coupling degrees of urban land intensive use socio-economic benefits and eco-environmental benefits was at an antagonism development stage, the coupling degrees decreased slowly; (3) The coupling coordination degree of urban land intensive use socio-economic benefits and eco-environmental benefits experienced moderate coordination level and high coordination level.
