Drilling and Completion Fluids

The addition of a ‘state of the art’ Drilling & Completion Fluids core test rig has expanded the formation damage capabilities of the Core Analysis section at Scaled Solutions Ltd. This high specification test rig allows the Formation Damage potential of oil or water based Drilling & Completion fluids under full reservoir conditions, for 3-phases (oil / brine / gas) and at HTHP. 
 
Coupled with our existing technology in conventional Formation Damage and Chemical Treatment core testing, Scaled Solutions Ltd can now provide a complete service from initial drilling through to “late life” field production.
 
The open annulus core holder design allows viscous drilling / completion fluids to be applied to the core plug face semi-dynamically at field overbalance pressures closely replicating well operations. Filtrate loss (leak-off) is accurately measured using a precision Quizix pump. The test rig set-up allows drawdown can be performed either at constant rate / incremental (under-balance) pressure or constant pressure / incremental rate.
