What data is contained in Casing Records?

This article provides an outline of the key data points associated with well casings, highlighting the significance of each component in the context of drilling operations.

Casing records are included in the the completion data from many states. Casing records are a key component of well construction and allow for better comparisons between wells and drilling strategies.

Key Attributes of Casing Records

While our data model contains a complete list of the attributes and their data definitions, the below provides information on many of the key data points.

1. Casing Size: refers to the diameter of the casing pipe used in a well. It's typically measured in inches and is a critical factor in well design. The size of the casing affects the well's production capacity and the types of equipment that can be used inside the wellbore.
2. Casing Type: describes the specific category or classification of the casing being used. Different types of casings serve various purposes, such as surface casing, intermediate casing, or production casing. Each type is designed to withstand different pressures and environmental conditions at various depths.
3. Casing Weight: represents the weight of the casing, measured in pounds per foot. This property is important for calculating the total weight of the casing string and ensuring that it can withstand the pressures and stresses it will encounter in the wellbore.
4. Cement Sacks: indicates the number of cement sacks used in the casing operation. This information is vital for understanding the volume of cement used to secure the casing in place and create a seal between the casing and the wellbore.
5. Cement Class: is an open text field describing the class of cement being used (e.g., Class A, C, etc.). Different cement classes have varying properties and are used based on well depth, temperature, and pressure conditions.
6. Lower Set Depth:  represents the deepest point at which the casing is set in the wellbore. This measurement displays the extent of the casing's coverage and its role in well integrity.
7. Upper Set Depth: indicates the shallowest point of the casing string. Together with the Lower Set Depth, it defines the interval of the wellbore that is protected by this particular casing section.
8. WellboreSize: refers to the diameter of the drilled hole at the depth where the casing is set. 
9. Completion Date: marks when the well was completed, signifying the end of the drilling and casing process and the beginning of production or injection operations.
10. WellDatabase Dates: find when a record was cataloged, created and last modified using the dates. To understand the difference in these significant dates, click here.
