D-Lay breaker controlled release agent is used as a self-degrading fluid loss control additive when fluid loss control is desired for a period of time and a fluid loss control pill is used. It is used in combination with D-Grade self-destructive bridging agent, as a component of the internal breaker or bridging package of self-degrading solids-laden or crosslinked hydroxyethyl cellulose (HEC) fluid loss control systems, to achieve required delay time above 200 degF [93 degC].
D-Lay agent is recommended for bottomhole temperatures above 200 degF [93 degC]. At these temperatures, D-Lay agent hydrolyzes and inhibits the D-GRADE agent reactivity rate to help achieve the required delay time.
The agent may not activate below 200 degF [93 degC]. Lab testing is required.
