Drill and complete openhole intervals
PRIMO systems are a suite of low-oil/water-ratio fluid systems designed to help drill and complete openhole intervals entirely in an oil-based environment.
PRIMO-FAZE low-oil/water-ratio reversible nonaqueous reservoir drill-in fluid system
The PRIMO-FAZE low-oil/water-ratio reversible nonaqueous reservoir drill-in fluid system provides better production rates, environmental acceptability, reduced waste generation, and easy cleanup to preserve the integrity of the reservoir. For use in high-pressure formations, the fluid is compatible with a variety of high-density internal-phase brines to increase density.
PRIMO-SCREEN low-oil/water-ratio screen running system
In applications that require minimal completion-compatible solids, the PRIMO-SCREEN low-oil/water-ratio screen running system can use mixtures ranging from 50:50 to 20:80 brine/oil ratio—and even up to 10:90 in extreme cases—to reach the required density. Depending on the application, this fluid can also accept properly-sized bridging agents.
PRIMO-SWELL oil-swellable-packer activation system
When drilling with a water-based drill-in fluid and the well completion plan requires oil-swellable packers, the PRIMO-SWELL oil-swellable-packer activation system enables precise, predictable packer swelling. When required, the PRIMO-VIS viscosifier can be used in the PRIMO-SWELL system to suspend ultra-fine weighting agents.
PrimoPAC invert-emulsion gravel-pack carrier fluid
The PrimoPAC invert-emulsion gravel-pack carrier fluid minimizes risks when transitioning from a synthetic- or oil-based drill-in fluid to a brine-base carrier fluid and spacer for openhole gravel-pack (OHGP) completions. This unique fluid enables the wellbore to remain oil-wet throughout the completion phase, avoiding issues such as shale instability, dispersion, and crossfluid compatibility.
