Drilling Performance Initiative in Campos Basin Block C-M-592

Abstract

Drilling exploratory wells in Campos Basin shallow water has been done before. However, if you put in place an aggressive exploratory campaign to drill 40 wells in less than 2 years, with more than 4 semi-submersible rigs new to the area and all for a recently created operating company, you are facing quite a challenge.The lithology of the wells in block C-M-592, pore pressure profiles and the requirement for formation evaluation while drilling are challenges that needed to be addressed in the design and drilling of these wells. In addition, multiple bit trips, low ROP, and high drilling vibrations have also contributed to increased non-productive time (NPT) with the associated costs.An integrated approach to engineering and real time monitoring has been the key to controlling the operations and understanding block C-M-592 in Campos basin. In addition, the application of appropriate new technologies along with standardized, fit-for-purpose practices that have been implemented since the beginning of the drilling campaign have resulted in performance improvements.

Análise dos desafios e soluções para aprimorar o desempenho operacional de poços de exploração no pré-Sal brasileiro.

“…According to Flores et al (2011), the drilling campaign in block C-M-592 in the Campos basin has witnessed a significant reduction in drilling times, exceeding 30%, as a result of implementing appropriate new technologies and standardised, fit-for-purpose practices.…”

“…A loss of experienced workers in the company is detrimental because it gives it a characteristic of a new company, hence, old challenges could become new challenges to new workers, this can pose a significant challenge as stated by Flores et al (2011) that an aggressive exploratory campaign to drill wells within a short time poses a significant challenge for a newly created operating company. Therefore it was essential to keep the experience alive for delivering quality services.…”
