ENVIRONMENTAL IMPACTS OF THE OFFSHORE DRILLING ACTIVITIES IN THE BLACK SEA

Öz

The main aim is to evaluate the environmental effects and potential problems of drilling activities in the Black Sea. The work consists of two parts: The first part focuses on the current pollution situation in the Black Sea, specifically offshore drilling activities. It is also mentioned about the effect of post-drilling in the Black Sea. The second part is the general environmental effects of drilling activities in the seas. These environmental effects were examined under three main headings: Produced water, drilling fluids and cutting wastes. Afterwards, they were examined within the scope of offshore drilling activities in the Black Sea.

KARADENİZ'DEKİ AÇIK DENİZ SONDAJ FAALİYETLERİNİN ÇEVRESEL ETKİLERİ

Öz

Çalışmanın ana hedefi Karadeniz’de yürütülen sondaj faaliyetlerinin olası çevresel etkilerini ve oluşabilecek sorunları değerlendirmektir. Çalışma iki kısımdan oluşur: Birinci kısım Karadeniz’de halihazırda mevcut olan kirlilik durumudur. Bu kirlilik durumu, açık deniz sondaj faaliyetleri özelinde incelenmiştir. Ek olarak, Karadeniz’de sondaj yapılan bölgelerin sondaj sonrasında nasıl etkilendiğine de değinilmiştir. İkinci kısım ise sondaj faaliyetlerinin denizlerdeki genel çevresel etkileridir. Bu çevresel etkiler; üretimden kaynaklı su, sondaj sıvıları ve sondaj deliği için kesme atıkları özelinde üç ana başlıkta incelenmiştir. Sonrasında bu başlıklar, Karadeniz’deki açık deniz sondaj faaliyetleri kapsamında incelenmiştir.
