tNavigator 16: Perforation History Table

Summary

The transcript covers a detailed step-by-step guide on how to manage data for a well perforation operation using software tools like T Navigator. It includes the process of defining well structure, casing, tubing, and perforation events, focusing on perforation depth, event dates, and key parameters like skin multiplier, inside and outside casing diameter, and roughness. The script emphasizes data organization, proper format handling, and the creation of tables to input crucial well data, all essential for defining a development strategy and ensuring effective operation in perforation and production scheduling.

Takeaways

• 😀 The script outlines the process of working with well structures, including the perforation, history, and event tracking.
• 😀 Perforation events, like squeeze or pluck, are important for well operations and need to be manually recorded and tested.
• 😀 The casing, tubing, packer, and perforation depth are all significant parts of the well structure and need detailed tracking.
• 😀 Key parameters for perforation include the inside diameter, outside diameter, hole roughness, and skin multiplier of the casing and tubing.
• 😀 The script mentions the use of a table from T Navigator for organizing and analyzing the data related to perforation events.
• 😀 The process involves importing a table, adding rows, and inputting data with proper formatting, including skipping specific lines and columns.
• 😀 Special attention is given to the format of dates, and ensuring the event types and well details are properly recorded.
• 😀 The event types in the well structure include the top and bottom perforation depths, which are critical for performance analysis.
• 😀 Data fields such as the well, date, and perforation details are central to the setup of the system for tracking well operations.
• 😀 The script also involves defining global rules and strategies for well operation development, as seen in the opening of new windows in the software.

Q & A

What is the main focus of the script provided?

The main focus of the script is on the process of perforation in well operations, including well structure, event data, casing, and tubing details, as well as the use of software to manage and analyze this information.

What is meant by 'perforation' in this context?

In this context, perforation refers to the process of creating holes or openings in the casing of a well, typically to allow for the flow of oil or gas from the reservoir into the wellbore.

What are some of the key parameters involved in the perforation process?

Key parameters in the perforation process include the perforation top and bottom depth, inside and outside diameter of the casing, roughness of the tubing, and the porosity system.

What is the significance of the 'skin multiplier' in the context of perforation?

The skin multiplier is a factor used to adjust the well's productivity index based on the impact of formation damage caused by perforation or other activities. It helps to estimate the efficiency of fluid flow.

Why is it important to change from radius to diameter in the script?

Changing from radius to diameter is necessary for accurately representing the size of the perforation or hole in the casing, as the diameter is more commonly used in wellbore measurements and calculations.

What is the purpose of skipping certain lines when importing data into the software?

Skipping certain lines, such as the first line or specific columns, helps to ensure that only relevant data is imported into the software, preventing errors or inconsistencies in the dataset.

What role does the 'well structure' play in the software setup?

The well structure helps organize and define the various components of the well, such as the casing, tubing, and perforation events. This allows for accurate tracking and analysis of the well's operations.

What does the term 'event' refer to in the script?

In the script, the 'event' refers to specific activities or operations performed on the well, such as perforation, which are tracked in the dataset with associated dates and depths.

What is the importance of ensuring that the date format is consistent in the data?

Consistency in the date format is crucial for proper data analysis and processing. It ensures that the software can correctly interpret and sequence events over time.

How is the 'development strategy' defined in the software?

The development strategy in the software refers to the set of rules and parameters that define how the well will be managed and optimized, including operations such as perforation, production, and testing.
