Customer Challenge
Common causes of formation damage related to drill-in and completion fluids:
▌ Fine drilled solids and foreign particle invasion and plugging
▌ Formation clay swelling, dispersion, migration, and blocking of the flow channels
▌ Drilling fluids that are chemically incompatible with natural reservoir fluids
▌ Fluid invasion
▌ Emulsion and water blocking
Years of Production
Reducing formation damage can help reservoirs to produce at higher rates, resulting in faster payouts for the operator

Case Study – Reservoir Drill-In Fluid Minimizes Fluid
Invasion and Mitigates Differential Stuck Pipe
Location: Saudi Arabia
CHALLENGE:
 The operator faced production challenges on freshly drilled sandstone reservoirs due to plugged sand screens on production, which put the well on workover operations in less than a year. Investigations showed that the water based drill-in fluids previously used in the well allowed fluids and fines to invade the formation and plug the sand screen during production.
 The objectives were to: minimize fluids invasion; minimize formation damage; no differentially stuck pipe; no down hole losses; and no tight spots.
SOLUTION:
 Baroid proposed an integrated approach of: customized BARADRILN® reservoir drilling fluid; Drilling Fluids
Graphics (DFG) software to monitor hole cleaning and Equivalent Circulating Density (ECD); Particle Plugging
Test (PPT) and Particle Size Distribution (PSD ) to monitor fluid and solids invasion.
RESULT:

The earliest initial flow back saved 40 hours rig time, thus saving the operator 58,000 USD
 In addition, a 25% increase in production was observed, thereby maximizing the wellbore value.
