PETROPHYSICS

Petrophysics is the study of the physical and chemical properties of rocks and their contained fluids.

WHAT IS?

PETROPHYSICS

The tools available to the petrophysicist are:

Mud logging (solids, liquids, gasses, volumes, rates, concentrations and temperature)

Measurement while drilling (MWD) and Logging while drilling (LWD) Wireline logging (open- and cased-hole) Core sampling [(wireline (percussion and drilled) and whole] and core

analysis Fluid sampling (wireline and/or drillstem tests)

This list is arranged in order of the usual acquisition sequence.

MUD LOGGING

Mud logging (or Wellsite Geology) is a well logging process in which drilling mud and drill bit cuttings from the formation are evaluated during drilling and their properties recorded on a strip chart as a visual analytical tool and stratigraphic cross sectional representation of the well.

Provide continuous record of penetration rate, lithology and hydrocarbon shows.

These information supports wireline log data.

From the cuttings, an oil stains or odor of oil may be detected, become an excellent qualitative indicator.

The fluorescent lamp is also a great help in detecting oil shows.

FORMATION EVALUATION

Formation Evaluation (FE) is the process of interpreting a combination of measurements taken inside a wellbore to detect and quantify oil and gas reserves in the rock adjacent to the well. FE data can be gathered with wireline logging instruments or logging-while-drilling tools.

Study of the physical properties of rocks and the fluids contained within them.

Data are organized and interpreted by depth and represented on a graph called a log (a record of information about the formations through which a well has been drilled).

What is Formation Evaluation?

CORE ANALYSIS

Core Analysis is the study of formation samples (cores) drilled out by means of special bits.

Core analysis provides information for reservoir description, characterization and simulation; log calibration; recovery methods.

These information are measured in the laboratory.

Can be divided into two categories: Conventional or Routine Core Analysis (RCAL). Special Core Analysis (SCAL).
