Welcome to Petroleum Geology Forums

Hi everyone,
I am currently working on some old well logs, but i am having challenges in identifying the Mnemonics of the curves, some of the curves names are listed below
1. Interval Transit Time
2. Formation Density
3. Spontaneous Potential
4. Lateral log
5. Density correction
6. Bulk density
7. Neutron Porosity
8. Resistivity (short normal and long normal)
.they are all Schlumberger Logs

Please every meaningful contribution will help and greatly appreciated.

THANKS

The mnemonics for the Schlumberger logs and services are as follows:
1. Interval Transit Time: ITT (microseconds, us)
2. Formation Density: PORDC'>FDC (Formation Density Compensated, gm/cc or kg/m3)
3. Spontaneous Potential: SP (millivolts, mV)
4. Lateral log: LL (usually LLD Deep Laterolog and LLS Shallow Laterolog, ohm.m)
5. Density correction: DRHO (gm/cc or kg/m3)
6. Bulk density: RHOB (gm/cc or kg/m3)
7. Neutron Porosity: NPHI (dec., v/v, p.u. or %)
8. Resistivity (short normal and long normal): SN and LN (ohm.m)

I have provided these mnenomics based on my knowledge and past experience as a Schlumberger engineer.
You can Google if you want a complete list of Schlumberger logs and services. There is also a complete list of log mnemonics for different well logging companies on the SPWLA web site.

Thanks kokokyi, I really appreciate.
