Class Code: 6237
Per NCCI's Scopes Code Description:
Code 6237 applies to the detection and analysis of oil or gas by conducting oil or gas flow tests such as, but not limited to, hole pressure tests, well temperature tests, well depth tests, and volume tests. Additional work classified to Code 6237 includes tests to determine if a drilled hole is straight or, if not, its angle of deviation.
Operations involving tests to determine the characteristics of the earth’s formation through which a hole has passed are also classified to Code 6237. Usually, the described testing operations involve lowering various specially designed instruments into the wells to obtain the needed data.
Employers that conduct on-site oil analyzing and testing services from trailers located at well sites but not at the well drilling area are also classified to Code 6237.
Flowback engineers who only monitor and log flowback pressure are also included in this classification. Flowback refers to a process by which the fluid used for fracturing a shale formation is recovered from the well at the surface. Flowback is performed in preparation for a subsequent phase of treatment, or to clean up and transition the well to a production stage. Installation, repair, or servicing of equipment used for flowback purposes is not assigned to Code 6237.
This classification is intended to apply to logging or survey work, which means maintaining records and/or taking measurements. While these activities are considered wire line services by the industry, other wire line-type work involving the installation, repair, or servicing of equipment used for drilling purposes is not included in Code 6237. Examples of this wire line work include retrieving pipes or other items from a well; well cleaning; and valve, plug, or tubing installation, service, or repair.
Extra-Territorial Classification Guidelines:
The following material was developed by NCCI to be used as a guide by auditors and underwriters in the determination of premium for contracting (construction risks) with extra-territorial employments where no company guidelines have been established for this purpose. Construction classifications are indicated by the addition of a construction code symbol (•) next to the classification code number.
When a portion of the operations of a risk are insured in a monopolistic state fund, consider the special rules and requirements that may exist in such cases.
