Management and Rcycling of Drilling Waste Water
Authors B. Ekizer, Ş.D. Atay, N. Köse, E. Buzpınar, H. Baran and B. KayahanThe rapidly increasing world population occurs in parallel with an increase in the need for human fuel), Therefore the number of oil and gas drillings in the world that has increased with from day to day). Due to, the more Increase in drilling activities in question occurred during drilling activities along with a resultant, the more increase in the problems of environmental pollution caused by drilling waste and field used, such as TPAO’s exploration – production drilling companies have led to research and development.of new production methods on waste disposal in the drilling waste. As most people know that, the most important of emerging waste, drilling mud waste during drilling activity. Drilling mud,is a special liquid, used to provide transportation to earth’s surface of the cut soil structures during drilling activity, and also other special purposes. During the preparation of drilling mud, to keep under control the physical and chemical properties (specification) of mixture, it is used a wide variety of organic, inorganic and antibacterial chemical substances. Drilling mud, mixed with cuttings from the ground to surface is taken, physically separated from mud and collected in mud-pits. Cuttings from mud in a successful separation drilling mud and cuttings store as individual waste. However, it is usually not possible in the full, Cuttings contain a large amount of waste drilling mud. TPAO, waste disposal methods in drilling mud, oil companies operating in the international arena in the world, widely used on-site(insitu) evaporation, injection and water treatment technologies are applications. In general, treatment technologies, waste water recycling and reuse of drilling, because it provides is advantageous compared to other disposal methods. The pilot mobile waste water treatment system which is started to use under the control of TPAO HSE Department is Chemical mixing tank, filterpres unit and water storage tank mainly and its capacity is almost 15 tons per day. At the final stage of pilot field treatment aplications in TPAO, it has been gained treated water which treated COD, Suspended Solids, Oil-gres, Na, Fe and Sulphure almost with %87,5 - %99,5 eficiency. At the same time, it has been seen that, this treated water is in dischargeable limits according to Water Pollution Control Regulation – Table 11.03.

Health, Safety and Environmental (HSE) Practises in Tpao Offshore Projects
More LessThe offshore activities are carried out by TPAO since 1970 in the Turkey’s seas. In this context, offshore activities was tried under relevant common licenses with BP in Eastern Black Sea, with Chevron and Tiway Company in Western Black Sea, with Petrobras and ExxonMobil Company in Central Black Sea. Firstly, deep sea offshore studies were began in Trabzon sea area in Hopa-1 well with BP-TPAO Partnership in 2005 inIn Later studies, Sinop-1 and Yassıhöyük-1 wells were planned with Petrobras-TPAO and TPAO-Chevron at the beginning in 2010 as joint venture study. Finally Surmene-1 well was drilled in the end of 2010. In the last three wells drilling rig platforms in the world’s largest flag of Norway “ Leiv EIRIKSSON” drilling rig was used. Yassıhöyük-1 and Sürmene-1 wells drilling operation in the Black Sea by TPAO is important study about providing international HSE standards of Turkey. In this context, the service procurement has been provided for emergency medical services, This services include; medical response (7 days 24 hours work, traffic accidents, etc.) at the facility in the cases of emergency, to transportation of sick and ill/injured staff from sea by helicopter ambulance and conveying staff to hospital for delivery of a fully equipped service. In the same time, the exercises relevant to this services has been made in the platform. Within the framework of the Oil Pollution Emergency Response services, preparing of Oil Pollution Dispersion Modelling, Geographic Response Plan and Sensitive Area mapping reports, to response for Level 1-2 Intervention services and equipment leasing, to training about “Incident /Crisis Management” have been provided and exercises has been made about this issue. In addition for determining of marine environment condition under Yassıhöyük-1 project, “Drilling Revenue Distribution Modeling”, “Characterization of Marine Environment, Annual Report of the Effects Assessment and Precautions” and “Environmental Management Plan” was prepared. On the other hand, certification was made for supply vessel for this Offshore Project first time according to Turkish certification regulations and rules of Marpol 73/78 Annex-1, 4 and 5 . “Ship Waste Import License Certificate” was given to foreign supply vessel for transportation of waste from platform to port land by Zonguldak and Trabzon District Manager of Ministry of Environment and Forestry.

Emergency Response and Risk Assessment Plan for the Coastal Facility of Turkish Petroleum Corporation
Authors B. Ekizer and P. Aydoğduy is party to Barcelona Convention, Bucharest Convention, MARPOL 73/78, OPRC 1990 CLC 92 and Fund 92 Protocols. In this situation, an important step has been achieved by a new law No. 5312 on response to emergencies and compensation of losses in case of pollution of marine environment from oil and other harmful substances sharpens that came into force in March 2005. The aim of the new law is to determine the principles and procedures to respond to pollution of marine area by accidents of ships or activities in the coastal areas and to limit and prevent this kind of pollution in case of emergency, to determine the liability and compensation after an accident, to fulfill the international obligations and to determine the authorities, duties and obligations of the authorities and other organizations involved. According to this law, one national, 6 regional Emergency Response and Risk assessment Plans are prepared. Turkish Petroleum Co. has 3 coastal facilities which are Kuzey Marmara and Değirmenköy Underground Natural Gas Storage, Marmara Ereğlisi Crude oil Transfer and Çayağzı Natural Gas Production. For these three coastal facilities Emergency Response and Risk Assessment Plans are prepared and approved by Ministry of Environment and Forestry. In addition, for there facility Trier-1 and trier-2 training programme and practices are organized in 2010.
