Gas Industry

Produced water is the largest waste stream generated in oil and gas industries. It is a mixture of different organic and inorganic compounds. Due to the increasing volume of waste all over the world in the current decade, the outcome and effect of discharging produced water on the environment has lately become a significant issue of environmental concern. Produced water is conventionally treated through different physical, chemical, and biological methods. In offshore platforms because of space constraints, compact physical and chemical systems are used. However, current technologies cannot remove small-suspended oil particles and dissolved elements. Besides, many chemical treatments, whose initial and/or running cost are high and produce hazardous sludge. In onshore facilities, biological pretreatment of oily wastewater can be a cost-effective and environmental friendly method. As high salt concentration and variations of influent characteristics have direct influence on the turbidity of the effluent, it is appropriate to incorporate a physical treatment, e.g., membrane to refine the final effluent. For these reasons, major research efforts in the future could focus on the optimization of current technologies and use of combined physico-chemical and/or biological treatment of produced water in order to comply with reuse and discharge limits.

A number of countries have recently discovered and are developing oil and gas reserves. Policy makers in such countries are anxious to obtain the greatest benefits for their economies from the extraction of these exhaustible resources by designing appropriate policies to achieve desired goals. One important theme of such policies is the so-called local content created by the sector—the extent to which the output of the extractive industry sector generates further benefits to the economy beyond the direct contribution of its value-added, through its links to other sectors. The use of industrial policy in the petroleum sector to support broad-based economic growth is hardly a new trend in the oil and gas sector. Local content policies (LCPs) were first introduced in the North Sea in the early 1970s and ranged from restrictions on imports to direct state intervention in the oil sector. Over time the aim of LCPs has evolved from creating backward links (that is, supplying input to the local economy through transfer of technology, the generation of value-added in domestic supply sectors, the creation of local employment opportunities, and increasing local ownership and control) to creating forward links link (that is, processing the sector’s output prior to export through, for example, the establishment of refineries, petrochemical industry, and the production of fertilizers). While LCPs have the potential to stimulate broad-based economic development, which is necessary to alleviate poverty and achieve the United Nation’s Millennium Development Goals (MDGs), their application in petroleum-rich countries has achieved mixed results. The use of specialized inputs and the technological complexity of the petroleum sector often limit the possibility of developing backward and forward links into the local economy. An economy that is very limited can hardly be expected to quickly supply services (let alone build forward links). A fast-growing petroleum sector coupled with too ambitious local content targets may exacerbate supply bottlenecks arising from increased aggregate final demand. This would ultimately affect employment and output trends in other sectors of the economy, create distortions and inefficiencies, and in some cases even promote corruption. Furthermore, the size and location of petroleum projects also affect the type of potential links, and the speed at which they can efficiently develop. The use of LCPs raises a number of questions:

What exactly is “local content”?
What is the extent of local content in the oil and gas sectors?
Why is increasing local content good for development?
What types of policies can be used to encourage an increase in local content?
What are the costs and benefits of introducing such policies?
How can the implementation of such policies be monitored and how can their impacts be measured?
What are the lessons to be learned from oil- and gas-producing countries that have implemented policies to increase local content?
This study serves to introduce the topic by describing policies and practices meant to foster the development of economic links from the petroleum sector, as adopted by a number of petroleum-producing countries both in and outside the Organisation for Economic Co-operation and Development (OECD).

Over the years, Information Technology (IT) has struggled with how to create an effective structure and processes. It is our main thesis that if organizations focused more on implementing a sound IT governance strategy, it might help senior executives to manage not only the IT-related activities, but also the perceptions between IT and the rest of the organization, and, in doing so, foster a more successful IT organization. Using six case studies conducted within the oil and gas industry, we explore differences in perceptions toward IT and in the organization of IT activities. Using an Extended Platform Logic Perspective, we note differences and similarities between the firms, with respect to IT capabilities, relational and integration mechanisms, measures of success, and relationships with the business units. Our results suggest that our colleagues-in-practice have evolved from focusing on one-way architectures within a centralization/decentralization context toward a two-way relat...
