Mud Parameter

MP temperature, pressure, mud resistivity, total natural gamma activity, motion detector TEMP (analog) temperature

200 °C with P-sensor, w/o 250 °C/ 130 MPa/86 or 92 mm/4.8 m/70 kg/ 110 mm 300 °C/130 MPa/86 mm/2.85 m/100 kg/ 110 mm

Electric MSFL (analog) micro spherically focused log (with pad) SP-Redox (analog) spontaneous & redox potential

157 °C/136 MPa/110 mm/3.3 m/95 kg/ 160 mm 125 °C/80 MPa/90 mm/3.1 m/50 kg/ 110 mm

Gamma GR (analog) total natural gamma activity SGR (digital) natural gamma spectrum: U/Th/K, total GR

157 °C/136 MPa/96 mm/3.4 m/37 kg/ 110 mm 157 °C/136 MPa/110 mm/3.4 m/80 kg/ 140 mm

Sonic BCS (analog) 2-transmitter-2-receiver (with centralizers)

150 °C/104 MPa/96 mm/4.8 m/116 kg/ 110 mm

All sondes are combinable with GR for depth correlation, except the SP-Redox. Some Sondes have Schlumberger 31-pin cable head connections, others have Halliburton cable head connections. Cross-overs are available. BCS, MSFL, SP-Redox & BG require for a 7-conductor cable. MP, TEMP & SGR require just for a 4-conductor cable.
