Oil and gas development activities generating marine noise include seismic operations, drilling and production activities, offshore and nearshore structural installation (especially pile driving) and construction activities, and marine traffic. Noise from offshore activities (especially from seismic operations) can seriously harm fish and marine mammals, especially dolphins and wales.
Typical non-hazardous and hazardous wastes routinely generated at offshore facilities include general office and packaging waste, waste oils, oil contaminated rags, hydraulic fluids, used batteries, empty paint cans, waste chemicals and used chemical containers, used filters, fluorescent tubes, scrap metals, and medical waste, etc.
Produced water is water produced in association with crude oil, is by far the largest waste stream in most oil fields, accounting for up to 95% of total wastes. It is composed of a complex mixture of inorganic (dissolved salts, trace metals, suspended particles) and organic (dispersed and dissolved hydrocarbons, organic acids) compounds, and in many cases, residual chemical additives (e.g. scale and corrosion inhibitors) that are added into the hydrocarbon production process.
Vast quantities of gas and oil resources are in the process of being discovered under Portuguese waters. The government and executives of oil and gas companies, which includes such names as Repsol, Galp and Partex (an offshore company owned by the Portuguese Gulbenkian Foundation) have been telling us how great this will be for the country. But will it?
Here you find answers to some of the questions that we are asked on a regular basis. These should assist you in deciding for yourself whether you are pro or anti oil drilling in our offshore in the Algarve basin and Alentejo basin, by Repsol /Partex (Gulbenkian Foundation), by GALP/ENI or by Kosmos Energy or any other company that our blinded government deems worthy of an offshore license to drill for oil and gas. Although in this article we focus on Repsol /Partex concessions mainly.
