The telemetry equipment used by SPP Razvitie LLC is capable of performing gamma and wave resistivity logging both in real time with transmission to remote monitoring centres using WITS and WITSML protocols, and high resolution data retrieved from the instrument memory at the end of the trip, at the surface.
As an extension to the range of services provided, from 2019, our company will offer the use of a tele-system layout with a hydraulic communication channel, including the 2HNKT instrument. This instrument is designed to:
– determination of water saturated porosity of reservoirs
– identifying gas saturated intervals and lithological partitioning of the section
– calculating the cavernousness indicator curve
