f Problems Faced in Diyarbakır XI Region Wells and the Proposed Solutions

The area studied is located in Diyarbakır city territory inside XI. Oil Exploration and Production Region. In this study, reasons of the problems appearing in a time span and frequently faced, causing production loss and abandonment of the producing wells and consequence of those problems have been analyzed. For the wells to be drilled in the region, the points to pay attention during • Casing set depth, • Open hole logging, • Cementing, • Casing corrosion prevention, • Perforation interval selection, • Acidizing operations, reasons of rising watercut values, the effect of wrong x-y coordinate measurements, CDR logs taken minimum or none in deviated holes on preparation of misleading location maps and structural maps respectively and the consequence of these are explained. In the study, geology, drilling, reservoir, logging, production and workover data and information of total 87 producing and/or abandoned wells existing in the Southeast Anatolia, Diyarbakır XI. Region, where approximately for 40 years exploration and production activites are resumed, have been evaluated in details. Production loss during producing wells’ life span, reason/result relations of the problems causing to abandon wells have been examined and solution proposals have been presented for new wells to be drilled where similar problems can be encountered.
