Downhole Tools for LWD

Brief Introduction:

Downhole Tools for LWD WPR has an improved measurement accuracy, can precisely distinguish hydrocarbon and water zone, provide enough information about strata radical profile and true formation resistivity.

WPR will delineate the formation radical profile in detail by collecting resistivity information of different investigation depth.

WPR adopts symmetric compensated antenna design, which will eliminate borehole effect, drift effect of antenna and electronics system.

WPR has an excellent layer resolution——vertical resolution is 20cm.
