This thesis provides the background to and an analysis of the economics of exploring for and developing oil and gas discoveries in India. It is aimed at helping the oil and gas industry assess the financial attractiveness of investment in that country. The thesis describes the geography, climate, infrastructure, and energy market with an emphasis on how these affect upstream oil and gas industry investment. A detailed description and analysis is given of the petroleum production sharing contract (&quotPSC&quot) terms embodied in India's New Exploration Licensing Policy (&quotNELP&quot), and demonstrates that, depending on negotiations, Government Take under NELP terms is likely to be in the range 50% to 60% for a stand-alone petroleum development. However, PSC terms are regressive for marginal discoveries. In particular, State royalties might hinder the development of small or marginal discoveries and render them uneconomic. As an illustration, depending on the oil price, up to 6 MMbbls of oil in otherwise economically viable small fields in a geological basin might be made uneconomic and left stranded because of the effect of royalties. The thesis also analyses the economics of developing a sample of actual Indian oil and gas fields offshore the east and west coasts of the country in shallow and deep water. Onshore field developments are not analysed because of lack of data. All of the offshore developments analysed are profitable based on past and current economic conditions and knowledge. The majority are also relatively low-risk investments. Finally, the thesis evaluates the profitability of new oil and gas exploration and development offshore the east and west coasts of India. The required minimum size of new exploration prospects are in the range 10 to 17 MMbbls for oil prospects and 138 to 1,100 Bcf for gas prospects assuming a low probability of success. Once a new discovery is made, the required minimum economically developable reserves are 4 to 12 MMbbls for oil discoveries and 63 to 1,400 Bcf for gas discoveries.

<p> The Spraberry Formation is a Leonardian age submarine fan deposit restricted to the Midland Basin. The formation consists of very fine-grained sandstone, medium to coarse grain size siltstones, organic shales and carbonate mudstones. These rocks show variability in sedimentary structures and bedding types varied from thinly laminated to convolute laminations. Bioturbations were present in some samples and soft sediment deformation, such as water escape features, sediment loading and flame structures. </p><p> The Spraberry Formation is a naturally fractured reservoir with low porosity and low matrix permeability. Porosity measured varied from 2% in rocks with poor reservoir quality such as the argillaceous siltstone and mudstone while good reservoir rocks had an average porosity of 9%. Seven lithofacies were identified based on sedimentary structures, grain size and rock fabrics. Petrographic analysis showed four porosity types: (1) intragraular porosity; (2) dissolution porosity; (3) fracture porosity and (4) intergranular porosity. Fractured porosity was only observed in the argillaceous siltstone lithofacies. </p><p> The prominent diagenetic influences on the Spraberry Formation are: quartz cementation, quartz overgrowth, illtization of smectite, feldspar dissolution, clay precipitation, carbonate cementation, formation of framboidal pyrite and fracture formation. These diagenetic features were observed using scanning electron microscope (SEM) and in thin sections. Generally, petrophysical properties, such as porosity and permeability, vary gradually from reservoir rocks to non-reservoir rock. Observed trends where: 1) increasing organic and argillaceous content with decreasing porosity and 2) increasing carbonate sediments and calcite cements with decreasing porosity. Mineralogical analysis from FTIR showed an abundance of quartz and calcite, while illite is the prominent clay mineral observed in all samples.</p>
