APHRON ICS™Technologies:
An Evolution In Drilling, Workover &
Completion Fluid Solutions
 An
aphron has a very unique structure relative
to conventional bubbles and because of the
characteristics of this structure they offer
many benefits to drilling,
workover and completion fluids. Some of these features include:
- Solids free, internal bridging which improves drilling efficiency and causes minimal formation damage
- Tough, stable microbubbles which make for easier drilling in high angle and horizontal wells
- Elevated LSRV which assists with controlling invasion, stuck pipe risk as well as pressure transmission from the annulus into a depleted formation
- The sealing feature of aphrons (either due to the Jamin effect or the LaPlace pressures) drive a micro environment seal in larger openings
- Elevated
LSRV which assists with controlling
invasion as well as pressure transmission
from the annulus into a depleted formation,
- Reduced effects of high pressure differentials which provide an alternative to under balanced drilling
- Good cuttings transport which allows for quality cement jobs
- Non-wetting
due to the surfactant package and the
aphron structure,
- Controlled
contact angle (again due to the surfactant
package) which helps to minimize invasion
- The
sealing features of aphrons either due
to the Jamin effect (as would be the
case in low pressure small pore throat
diameter formations) or the LaPlace
pressures driven aggregated aphron micro-environment
seal in larger openings
- Use in low pressure environments
- Significant reduction in clean up time
- Improved field economies, including increased production rates
- Environmentally acceptable
Each
of these fluid features work independently
and in dynamic conjunction with the other
features during the drilling / workover
/ completion process depending upon the
type of seal that is required.
