Flare-Gas Recovery in Tunisia—From Liability to Value
The full-length paper describes the project evolution, from the first study to the implementable concept of energy production using the associated gas of two onshore facilities in Tunisia. Despite its complex composition, high carbon dioxide (CO2) content, high hydrogen sulfide (H2S) concentration, and the relatively low quantities of available flared gas, a technically and economically feasible solution was developed successfully.
Thyna Petroleum Services (TPS) is a Tunisian joint-venture corporation of the Tunisian governmental oil and gas company, Entreprise Tunisienne d'Activités Pétrolières (ETAP), and the Austrian oil and gas affiliated group OMV A.G. based in Sfax. One of the future objectives of TPS is to avoid, or at least reduce, flaring of associated gas contained in crude oil during oil production. A particular challenge is to discover a process that enables the use of the associated gas despite its untypical gas composition for valorization processes.
Use of the associated gas will also reduce greenhouse-gas emissions. Therefore, this project also could be considered as a Clean Development Mechanism (CDM) project (United Nations 2010).
CDM is an arrangement under the Kyoto Protocol that allows industrialized countries with an emission-reduction or emission-limitation commitment to invest in an emission-reduction project in developing countries as an alternative to more-expensive emission reductions in their own countries. Such projects can earn saleable certified-emission-reduction (CER) credits, each equivalent to 1 ton of CO2, which can be counted toward meeting the Kyoto targets.
Increasing energy prices over the last few years, as well as enhancements in the process area, make the use of associated gas more and more interesting. Furthermore, the pressure of environmental and political organizations to develop new alternatives to flaring is constantly rising.
TC Energy Plans To Move Equipment for Keystone XL Preconstruction Work
TC Energy is planning to start mobilizing heavy construction equipment to worker campsites and pipeline storage sites in Montana, South Dakota, and Nebraska in February to start preconstruction work on the Keystone XL Pipeline.
North Dakota, Texas Fuel Increase in US Natural Gas Venting and Flaring
According to a new report from the EIA, the volume of natural gas reported as flared reached its highest average annual level in 2018, 1.28 Bcf/D. With production soaring in the Bakken, Permian, and Eagle Ford plays, North Dakota and Texas accounted for more than 80% of that total.
Offshore Wind: The New Frontier in Powering Platforms?
Offshore wind makes up less than 1% of the current energy mix, but analysts have it pegged as a potential trillion-dollar business in the near future. That growth presents an opportunity for operators to reduce costs and their carbon footprint through the electrification of their offshore platforms.
