Oilfield Operations

Production of South Pepper Oilfield commenced in 1987. Since that time the North Herald and Chervil fields have been brought on line and have produced in excess of 18 million barrels of oil. Initially environmental management and monitoring strategies attempted to understand and predict changes to the ecosystems caused by acute impacts such as a major oil spill. Over the life of the project the emphasis in environmental monitoring has shifted from measuring for acute effects to measuring on a more sensitive scale to predict and monitor the chronic impacts of oilfield operations. Monitoring efforts consequently have changed emphasis so that a better understanding of impacts is now possible due to the introduction of a more rigorous experimental design.

Exploration And Production

Environmentally safe management of hydrocarbon exploration and production activities is becoming increasingly important, particularly in sensitive marine areas. LeProvost Environmental Consultants have been working closely with Hadson Energy Limited, Western Mining Corporation Ltd and West Australian Petroleum Pty Ltd to produce environmental impact assessments, environmental management plans and monitoring programs for oilfields recently developed on the North West Shelf. Many of the well sites are located in areas with sensitive ecological habitats, including coral reefs, seagrass beds, mangroves and prawn spawning and fishing grounds. Consequently, operators in these areas have been required to produce comprehensive Environmental Management Plans and Oil Spill Contingency Plans, to gain development and operating approvals from the Western Australian Government.Formulation of these plans begins with baseline surveys of the biological, physical and social characteristics of the study area. Hydrodynamic modelling of the metocean conditions produces oil spill prediction envelopes to highlight the areas that may potentially be affected by an oil spill, if one should occur. Site-specific oil spill response procedures are then designed to cater for the sensitive marine habitats of the area, using the resources that are available in the region to deal with an oil spill.Results to date from the Marine Biological Monitoring Programs for three oilfields have supported predictions that no significant adverse impacts on the environment would result from the development and operation of the oilfields.

Set Up

A method is presented for determining influent readily biodegradable substrate concentration (SS). The method is based on three different respiration rates, which can be measured with a continuous respiration meter which is operated in a cyclic way. Within the respiration meter nitrification is inhibited through the addition of ATU. Simulations were used to develop the respirometry set-up and decide upon the experimental design. The method was tested as part of a large measurement programme executed at a full-scale plant. The proposed respirometry set-up has been shown to be suitable for a semi-on-line determination of an influent SS which is fully based on the IAWQ #1 vision of the activated sludge process. The YH and the KS play a major role in the principle, and should be measured directly from the process.

Abstract The Waste Isolation Pilot Plant (WIPP), a US Department of Energy (DOE) facility, is a deep geologic transuranic waste disposal site designed for the safe disposal of transuranic (TRU) wastes generated from the US defense program. Monitoring is a key component of the development and operation of any nuclear repository and is important to the WIPP performance assessment. Initial concerns over the release of radioactive and chemical contaminants from the WIPP led to various monitoring programs, including the independent, academic-based WIPP environmental monitoring (WIPP-EM) program conducted by the New Mexico State University (NMSU) Carlsbad Environmental Monitoring and Research Center (CEMRC) located in Carlsbad, NM. The mission of CEMRC is to develop and implement an independent health and environmental monitoring program in the vicinity of WIPP and make the results easily accessible to the public and all interested parties. Under the WIPP-EM program constituents monitored include: (1) selected radionuclides, elements, and ions of interest in air, soil, vegetation, drinking water, surface water and sediment from within a 100-mile radius of WIPP as well as in the air exiting the WIPP exhaust shaft, and (2) internally deposited radionuclides in the citizenry living within a 100-mile radius of WIPP. This article presents an evaluation of more than tens years of environmental monitoring data that informed the public that there is no evidence of increases in radiological contaminants in the region that could be attributed to releases from the WIPP. Such an extensive monitoring program and constant public engagement is an ideal model for all nuclear waste repositories anywhere in the world.
