This report contains a short summary and analysis of the production drill holes deviations from design in the Chelopech Mine. The report presents the results from on-field measurements of drill hole deviations along their depth. It also... more
This work describes the functionalities of the drilling simulator to optimize well drilling utilizing offset data offering also training modules for novice and experienced drillers. It fully simulates the drilling process using WOB, RPM,... more
During the drilling process, we need to look at several aspects that need to be considered, including the drilling mud aspect which is one of the important aspects in a safe and efficient drilling process.The success of a drilling process... more
ZADCO owns more than 500 wells operating in UZ, UA & ST fields to contribute in achieving the production targets as set by the Shareholders. To ensure that wells operate as designed for their assigned life (or greater) with all risks kept... more
Resume of my work: The Rio Del Rey delta which represents the part of Cameroon’s margin situated at the North partof the Cameroon volcanic line, is the meeting point between three panafrican faults of the Benoue. . The South west part,... more
The development of unconventional shales started a new era in the oil and gas industry. These reservoirs represent a challenge to conventional drilling fluids since the fluid invasion, cutting dispersion, or shale swelling can lead to... more
The use of conventional survey interpolation methods, where a survey is typically taken at each stand of pipe, to determine well trajectories can conceal problems due to tortuosity that can potentially lead to missed targets and... more
