Vigor Provides Guidance on Wireline Logging for Well Perforation

China Vigor Drilling Oil Tools and Equipment Co., Ltd. has released a technical guide focused on wireline logging procedures for casing perforation in oil and gas wells. This process is critical for wellbore repair and monitoring formation pressures.

The company outlines a rigorous preparatory phase that includes pre-job meetings with key personnel, such as drilling engineers, geologists, and wireline supervisors. These meetings aim to clarify reporting structures and discuss operational details, including potential site-specific challenges like weather or well conditions.

Before deploying the perforating guns, a dummy run is recommended to verify the integrity of the casing and ensure it is free from obstructions. If pressure release is anticipated during perforation, specialized equipment like a wireline BOP and lubricator must be installed.

Accurate depth correlation is achieved through simultaneous logging of the casing collar locator (CCL) and gamma ray (GR). Depth calculations are double-checked independently before perforation commences. Vigor states its perforating guns are designed and tested to stringent industry standards.
