Description:
Drilling companies are facing the challenge of moving land rigs from site to site as quickly as possible on a more frequent basis. This industry challenge requires an assessment of how land rigs move in the field to improve the process. The industry is using different methods and procedures, but there is a need to determine which methods are best for cost and time savings. A rig move study is difficult, primarily because of the lack of standardization in the industry, but the potential benefit to both contractors and operators is immense.
Application:
Relevant data is in high demand from both contractors and operators throughout the land market. Meticulous observation and analysis of ten rigs participating in the rig move study yielded noteworthy data. Because of thorough measuring techniques and precise metrics, we were able to quantify the best methods for moving a rig. Documentation of the entire rig move process included rig up and rig down sequences, handling systems utilized, transportation methods, as wells as rig and pad site layouts and labor. Detailed time and motion studies provided data separated by piece of equipment and measured to the nearest minute.
Observations:
Many different variables exist in the rig move process, but we were able to determine the best methods by using proven techniques. These best methods include recommendations for the use of handling systems and equipment, a rig move timeline, definitions of the rig up and rig down sequences, and identifying potential bottlenecks in the process.
Significance of Subject Matter:
By collaborating with a large contractor in the land drilling market, we are able to apply the results of our study and implement improvements to their move procedures. These improvements, both design and process related, saved money and increased the number of wells drilled per year. Improving the process of rig moves resulted in faster, cheaper, and more efficient rig moves, and is beneficial to both contractors and operators.
