A substantial proportion of proven oil and gas reserves of the world is contained in the carbonate reservoir. It is estimated that about 60% of the world’s oil and 40% of gas reserves are confined in carbonate reservoirs. Exploration and development of hydrocarbons in carbonate reservoirs are much more challenging due to poor seismic imaging and reservoir heterogeneity caused by diagenetic changes. Evaluation of carbonate reservoirs has been a high priority for researchers and geoscientists working in the petroleum industry mainly due to the challenges presented by these highly heterogeneous reservoir rocks. It is essential for geoscientists, petrophysicists, and engineers to work together from initial phases of exploration and delineation of the pool through mature stages of production, to extract as much information as possible to produce maximum hydrocarbons from the field for the commercial viability of the project. In the absence of the well-log data, the properties are inferred from the inversion of seismic data alone. In oil and gas exploration and production industries, seismic inversion is proven as a tool for tracing the subsurface reservoir facies and their fluid contents. In this paper, seismic inversion demonstrates the understanding of lithology and includes the full band of frequency in our initial model to incorporate the detailed study about the basin for prospect evaluation. 3D seismic data along with the geological & petrophysical information and electrologs acquired from drilled wells are used for interpretation and inversion of seismic data to understand the reservoir geometry and facies variation including the distribution of intervening tight layers within the Miocene carbonate reservoir in the study area of Central Luconia. The out-come of the seismic post-stack inversion technique shows a better subsurface lithofacies and fluid distribution for delineation and detailed study of the reservoir.

碳酸盐岩储层中蕴藏着世界绝大部分已探明的石油和天然气储量。据估计，世界上约60％的石油和40％的天然气储量被限制在碳酸盐岩储层中。由于地震成像差和成岩作用引起的储层非均质性，碳酸盐岩储层中碳氢化合物的勘探和开发更具挑战性。碳酸盐岩储层的评价一直是石油工业研究人员和地球科学家的首要任务，这主要是由于这些高度非均质储层岩石所带来的挑战。对于地球科学家，岩石物理学家和工程师来说，从勘探和界定水池的最初阶段到生产的成熟阶段，进行合作至关重要，提取尽可能多的信息，以从野外开采出最大量的碳氢化合物，以实现该项目的商业可行性。在缺乏测井数据的情况下，仅从地震数据的反演中就可以推断出这些属性。在油气勘探和生产行业中，地震反演已被证明是追踪地下储层相及其流体含量的工具。在本文中，地震反演表明了对岩性的理解，并在我们的初始模型中包含了整个频率范围，以结合对盆地的详细研究以进行前景评估。3D地震数据以及地质和 从钻探井获得的岩石物理信息和电测井资料用于地震数据的解释和反演，以了解储层的几何形状和相变，包括中卢卡尼亚中部研究区中新统碳酸盐岩储层中的致密致密层的分布。地震叠后反演技术的成果显示出较好的地下岩相和流体分布，可用于油藏的描述和详细研究。
