..., tailor-made logging procedures was implemented which consisted of two runs: baseline (static condition) survey after 24 hours well shut-in and the main survey (dynamic condition) under A-annulus bleed off condition. As a result, two sources of A-annulus pressure were identified: across the safety valve...

... Abstract Sucker-rod artificial lift is one of the methods to lift hydrocarbons from a well to the surface, when the natural pressure from the reservoir cannot guarantee free flow. Presently, on the Oil and Gas market there is no downhole safety valve capable of closing and sealing...

... to restore production quickly. This method maintains well safety valve functionality and eliminates expensive workovers. INTRODUCTION One of the main problems in gas wells is the so-called liquid loading , which seriously influences the effective exploitation of hydrocarbons reserves, by restricting...
