Rig: Ensign 123

County: Martin County, TX

Challenges:

• Lost circulation – permeable / porous / fractured
  • Shale Stabilization
  • Filtration control
  • Good cement job on production string- PRO V+ Pre-Cement Spacer if cement losses or achieving a good shoe test is a concern.

Solutions/Product recommendations:

PROCOR recommended starting with preventative and maintenance sweeps for drill out with WBM or OBM:  When drilling out of surface or Intermediate casing shoe, (preventative maintenance) we recommend having a sweep batch mixed up containing 6-7ppb (PRO Sweep Aid). The sweep batch is viscosified for body, hole cleaning and product suspension, pumping 10-15bbls sweeps every 300’ – 500’.

Products on locations; PRO Sweep Aid, SB SuperCeal, PRO V+, PRO X

Results:

Operator has been successful minimizing losses on 22-25 of the rigs following this preventative sweep recipe.

Operator: Matador Resources

Well: John Callahan Fed Com 137H

Field: WC (Bone Spring)

County: Lea County, NM

Rig: Patterson 256

Challenges:

Arrived on location and starting mixing pill consisting of PRO V 30ppb, PRO X 30ppb, PRO HG 30ppb. Once pill was mixed weight went from 10ppg brine to 10.4ppg. Active system was 10.7ppg so we did not use barite to weight pill. Pumped pill down to depth of 5,543′ closed in the well and started to pressure up to seal fracture. Pressured up to 591psi with the 1st pump, it jumped really quick on the pressure only 11 strokes. Squeezed another 2 bbls at the most to get to desired 750psi, kept pressure on for 30 minutes. POOH to pick up tools to drill out DV tool.
