Herramienta HRLA

1. Registros Geofísicos Convencionales HRLA Ejemplos M. en C. Zenteno Jimenez Jose Roberto

2. Radial response of the array laterolog compared to HLLd and HLLs from HALS: borehole-corrected apparent resistivities in a thick bed as a function of the invasion radius. Rt = 10 Ohm-m, Rxo =1 Ohm-m, Dh=8 in and Rm = 0.1 Ohm-m.

3. Thin-bed response of HRLA tool (top) compared to HALS (middle) and DLL (bottom) in uninvaded formation. Dh=8" and Rm=0.1 Ohm-m

4. Response to thin beds with invasion, showing the added radial discrimination of the HRLA tool (top) compared to HALS (middle) and DLL (bottom). Radius of invasion in the resistive beds: Ri =15 in, Dh=8 in and Rm=0.1 Ohm-m

5. Borehole effect when the tool is centered.

6. Borehole effect when the tool is decentralized with 1 in stand-off. 

7. Field log showing comparison of the HRLA resolution with the DLL.

8. Comparison of HRLA and HALS data, showing reduced shoulder-bed effect and improved characterization of invasion which lead to a better (1D) inverted Rt

9. Groningen effect visible on the dual laterolog is absent from the HRLA response in the middle track

10. Horizontal well, comparison of HRLA with DLL. 

11. Imaging-inversion example from the Middle East.
