The increase in downhole pressure when a tight tolerance casing or liner string is run in hole – surge – can be detrimental to any well construction project, including risking uncontrollable losses and compromising wellbore integrity or alternatively demanding unacceptably slow tripping speeds.
Expro’s SurgeCure® technology has been developed to overcome the challenges in deploying and cementing long casing strings or liners with small annular clearances, particularly in weak formations, whilst offering all of the benefits of the SeaCure® cementing system.
SurgeCure® utilises autofill shoes, inflow diversion and the field proven SeaCure® inner-string cementing technology to maximise autofill flow capabilities to minimise surge pressures, reduce casing deployment risks and improve overall operational efficiencies.
Standard float equipment is produced in autofill configuration to provide all of the benefits of an inner-string SeaCure® cement operation in tight casing tolerance or reduced equivalent circulating density (ECD) window sections.
