Guidance Document Information
||Acceptable forms of alternative documentation that may be accepted in lieu of a cement bond log for the water protection string
||On November 28, 2016, DMME published the final updates of its Gas and Oil Regulation (4VAC25-150 et seq.) in Volume 33, Number 7 of the Virginia Register of Regulations. 4VAC25-150-280(C) contains the following requirement:
Each permittee completing a well shall complete a cement bond log for the water protection string. Permittees may petition the director to submit alternative documentation that demonstrates effective bond between the casing and the formation.
This requirement helps to ensure well integrity and the protection of groundwater resources. However, mechanisms other than a cement bond log exist that can demonstrate effective bond between the casing and the formation. The purpose of this document is to establish those acceptable forms of alternative documentation. The regulations take effect December 28, 2016.
