5. WIRELINE LOGGING 5.1 What is a Wireline Log

The tools required to make these measurements are attached to the drill string behind the bit, and do not use a wire relying instead on low band-width radio ... largest wireline companies are Schlumberger and Halliburton, although there is a range of smaller specialist companies too.

Chapter 5: Porosity - University of Leeds

(xiv) Vug porosity Porosity associated with vugs, commonly in carbonate rocks. It should be noted that if the bulk volume and dry weight, or the bulk volume, saturated weight and porosity of a rock sample is known, then the grain density can be calculated.

Chapter 10: Relative Permeability

Typical intermediate wettability relperm data are shown in Figures 10.17 and 10.18. The shape of the relperm curves is significantly different for the high and low rate floods. However, the volume of oil produced is similar. Figure 10.19 shows steady state data obtained from a core containing mobile kaolinite fines.

16. THE SONIC OR ACOUSTIC LOG 16.1 Introduction

16. THE SONIC OR ACOUSTIC LOG 16.1 Introduction The sonic or acoustic log measures the travel time of an elastic wave through the formation. This information can also be used to derive the velocity of elastic waves through the formation.

Thus, if we take a cylindrical rock sample with two flat faces A and B, and set a potential difference ∆E =E A-E B between its end faces, a currentI will flow through the rock from face A to face B (Fig. 17.1). If we measure the current and the potential difference, we can calculate the resistance of the rock sample using Eq. (17.1).

15. THE NEUTRON LOG 15.1 Introduction

15. THE NEUTRON LOG 15.1 Introduction The neutron log is sensitive mainly to the amount of hydrogen atoms in a formation. Its main use is in the determination of the porosity of a formation. The tool operates by bombarding the formation with high energy neutrons. These neutrons undergo scattering in the formation, losing energy

2. POROSITY - University of Leeds

between 0 and 1, or a percentage varying between 0% and 100%. Sometimes porosity is expressed in ‘porosity units’, which are the same as percent (i.e., 100 porosity units (pu) = 100%). However, the fractional form is ALWAYS used in calculations. Porosity is calculated using the relationship (2.1) where: V pore = pore volume V bulk = bulk ...

Basic Relationships of Well Log Interpretation

porosity logs (i.e., sonic, density, and neutron logs) are covered next, then the resistivity logs. Nuclear mag-netic-resonance logs, although they provide porosity (among other quantities of interest), are presented after resistivity logs. This is due in part to their recent arrival and to their relative absence in historical data archives.
