As natural gas pipeline systems have grown larger and more complex, the importance of optimization of design and operation of pipelines has increased. This paper examines the optimization issue for the Egyptian gas transmission pipeline network. Paradoxical effects can exist when expanding the capacity of natural-gas-transportation networks. This paper derives conditions where it can be expected, how the effect can be masked, and provide analysis to support identification in larger-scale networks. The present work describes the development of a 1D steady-state isothermal reservoir/surface gas-pipeline-network model.
This course is an overview of techniques for finding new opportunities, adding value and extending the life of old fields. It provides practical tools to help you screen your fields for additional upside. This course will raise your skill set beyond the basic petroleum engineering and geosciences. You will take away tools that provide you with ways to screen for new opportunities in your fields. This course is intended for production engineers, reservoir engineers, geoscientists and managers involved in screening for new opportunities in old fields.
Africa (Sub-Sahara) An 816-mile 2D seismic acquisition program was completed on the Ampasindava block, located in the Majunga deepwater basin offshore northwest Madagascar. The data will provide improved subsurface imaging of the large Sifaka prospect and will potentially mature additional prospects in the Ampasindava block to drill-ready status. Sterling Energy (UK) holds a 30% interest in the Ampasindava production sharing contract, which is operated by ExxonMobil Exploration and Production (Northern Madagascar) (70%). Asia Pacific Production began on the Liuhua 19-5 gas field in the Pearl River Mouth basin in the South China Sea. The field is expected to hit peak production of 29 MMcf/D this year. China National Offshore Oil Corporation (100%) is the operator. Drilling began on the YNG 3264 and the CHK 1177 development wells onshore in Myanmar.
Africa (Sub-Sahara) Eni discovered gas and condensate in the Nkala Marine prospect offshore Congo. The discovery could hold from 250 MMBOE to 350 million MMBOE in place, the company said. In a production test, the Nkala Marine 1 discovery well in the Marine XII block yielded more than 10 MMcf/D of gas and condensate. Eni is the operator with a 65% interest in the block. The remaining shares are held by New Age (25%) and Societé Nationale des Pétroles du Congo (SNPC) (10%). Sonangol and Total will break ground on a deepwater oil pumping project that will increase Angola's production by more than 30,000 B/D.
This panel session will highlight and discuss high-level approaches to innovation in gas field development which may provide opportunities for enhanced cost efficiency and risk management. We will explore key issues faced by gas project developers and identify innovative solutions to support long-term gas field value whilst meeting regulatory requirements and societal expectations. The panel will share their experience in meeting these challenges against a backdrop of a continually changing business environment.
Price volatility of natural gas is expected to persist for the next couple of years. Hence, the natural gas industry will continuously transform through cost-effective CAPEX and OPEX, technology, digitalisation, increased productivity and better reservoir recovery. This comprehensive and focused workshop will be an avenue for discussions revolving around best practices and lessons learnt in combating challenges in gas resources, environment and infrastructure. Technological advancement and innovative solutions in gas field development projects within the current business environment will also be covered at this event.
Table 1 shows the gas-field-size requirements and typical world-scale plant sizes for some of the gas utilization options. The gas-field-size requirements are based on a single-train plant with a 20-year life. A combination of different gas monetization options also can be used depending on the available gas reserves. Table 2 compares the total market size for the different products for year 2001. Figure 1 depicts the impact of an additional 1,000 MMscf/D of gas on the product market.
Converting gas to liquids (GTL) through the Fischer-Tropsch (FT) route to monetize stranded gas has received increasing attention over the past few years. FT technology is a process that rearranges carbon and hydrogen molecules in a manner that produces a liquid, heavier hydrocarbon molecule. In general, GTL through the FT route refers to technology for the conversion of natural gas to liquid; however, GTL is a generic term applicable to any hydrocarbon feedstock. This page focuses on GTL processes based on natural gas feedstock. FT chemistry originated during the early 1920s from the pioneering work of Franz Fischer and Hans Tropsch at the Kaiser Wilhelm Inst.
It is widely accepted that global natural gas demand will continue to grow for the foreseeable future, possibly doubling every decade. Major new upstream developments, together with midstream transportation systems and downstream feedstock projects, are already progressing in all world areas. As this gas revolution evolves, there will be a dramatic rise in the requirement for high-accuracy measurement at every point in the gas value chain (Figure 1). Within these categories, there is a huge array of different gas-metering applications and a similar number of potential solutions. This can lead to confusion when selecting the optimum solution for the application.
