There is no drilling optimization without proper well planning. This research looked at optimal exploratory well design possibilities for two reservoirs (A and B) located within a Niger Delta X-Field, south of Nigeria. After much data analysis from both reservoirs the researchers concluded that reservoir A is a gas reservoir and reservoir B is an oil reservoir. Well design work was discontinued for reservoir A (the gas reservoir) because there are no gas facilities in place to transport and distribute possible gas production. Our research team carried out further analysis and completed the well design for optimal oil production from reservoir B (the oil reservoir). This study is inclusive of graph(s), well design assumptions, relevant equations and applicable calculations used in generating our design results (as summarized in a table). Various schematics to illustrate our optimal well design are also provided.
