Oil demand in India has grown rapidly in the past decade due to its rapidly advancing middle class. A national drive to improve environmental pollution is focusing on natural gas as a transitionary energy source due to its lower carbon emissions. Gas hydrate resources in India are huge and potentially represent a global energy game changer if the technologies for production from hydrate reservoirs are techno-economically established. Several initiatives have been undertaken by NGHP in India for gas hydrate exploration in deepwater offshore. Sustained rapid economic growth has made China and India increasingly important in the world economy.
Gas hydrate resources in India are huge and potentially represent a global energy game changer if the technologies for production from hydrate reservoirs are techno-economically established. Several initiatives have been undertaken by NGHP in India for gas hydrate exploration in deepwater offshore. Fabián Vera, Baker Hughes, and Christine Ehlig-Economides, Texas A&M, explain transient well analysis and how it contributes to shale development. It may not matter whether the IOCs or the NOCs are in charge. The work to be done is the same and the same people will likely be doing it.
Natural gas hydrates are considered to store vast amount of natural gas trapped in the subsurface worldwide. However, gas hydrates are yet to be commercialized due to technical challenges in the production technology. As a compact source of energy which is widely distributed, natural gas hydrates can play a big role in meeting future energy demands. But producing them is not such an easy task. Gas hydrate resources in India are huge and potentially represent a global energy game changer if the technologies for production from hydrate reservoirs are techno-economically established.
This article highlights interesting applications of machine learning in the oil and gas industry in drilling, formation evaluation, and reservoir engineering. Each project uses a data-driven model to solve a previously complex problem using machine learning to augment an existing solution. Considering most of the rigs deal with human-machine interface systems, the role of human factors is at the heart of any successful operation. Eye-tracking technology can be useful in real-time operation centers where ocular movement data can improve the professionals’ performance. As the petroleum engineering discipline embarks on its second century of existence, what changes will academia make to keep up with the times?
A computational fluid dynamics model is proposed to analyze the effect of hydrate flow in pipelines using multiphase-flow-modeling techniques. The results will identify the cause of pipeline failure, regions of maximum stress in the pipeline, and plastic deformation of the pipeline. The 9th International Conference on Gas Hydrates featured discussions on key advancements in flow assurance, including the concept of risk management and anti-agglomerates being applicable strategies in transient operations. A BP flow assurance manager explains a methodology for determining and mitigating flow assurance risks. A BP flow assurance engineer discusses the shift in hydrate management strategy from complete avoidance to risk mitigation for an offshore dry tree facility.
Operators are looking for ways to better handle water coming from subsea wells, which is typically treated at topside facilities. Subsea separation systems are not equipped to discharge water back into the reservoir, so how do companies close the gaps? High-fidelity 3D engineering simulations are valuable in making decisions, but they can be cost-prohibitive and require significant amounts of time to execute. The integration of deep-learning neural networks with computational fluid dynamics may help accelerate the simulation process. Saudi Aramco studied such algorithms to produce images simulating the flow inside a pipe’s cross section, possibly reducing the need for separator-based multiphase flowmeters.
This feature takes a look at the work being done by companies to improve corrosion inhibitor fluids and inhibition techniques for offshore projects. A wide range of corrosive elements and compounds from a variety of crudes has led to a renewed industry focus on corrosion and the effects it has on pipelines and vessels. As the world's supply of crude becomes heavier, many of the world’s oil producers will have to think more carefully about heavy crudes and the challenges they pose for processing, storage, and transportation. Semoga and Kaji fields experienced reservoir souring and suffered a history of calcium-carbonate (CaCO3) -scale cases before a proper scale-inhibition program was implemented. Problems with a free water knockout discovered continued scale issues, leading to investigation of the reasons.
The main goal of production logging is to evaluate the well or reservoir performance. Cenovus Energy announced that it reached 1 billion bbl of cumulative production from its oil sands facilities in northern Alberta, becoming the first company to reach this milestone using SAGD technology. The Delaware Basin presented a challenging scenario for Anadarko due to the company’s tankless development approach. Sand filtration was identified as a perfect fit for this application. Porosity from porosity log is never a measurement, it is a calculation, from what we think might represent the porosity of the rock.
In natural settings, such as the ocean bottom, when buried organic matter decomposes to methane and dissolves in water, clathrates form at temperatures greater than 277 K (4 C or 39 F). Biogenically produced methane in dissolved water forms hydrates very slowly, because of mass-transfer limitations. Over geologic time, the total enclathrated methane in the oceans has been estimated at 2.1 1016 standard cubic meters (SCM)--twice the energy total of all other fossil fuels on Earth. The amount of hydrated methane in the northern latitude permafrost is relatively small (7.4 1014 SCM), within the error margin of ocean hydrate estimates. Figure 1 shows world hydrate deposits in the deep ocean and permafrost, most of which were determined by indirect evidence such as seismic reflections called bottom simulating reflectors (BSRs).
