PORE WALL STABILITY IN CARBONATES UNDER VARYING GEOCHEMICAL CONDITIONS

Most of the world's giant fields produce hydrocarbons from carbonate reservoirs. As
more than 60 per cent of the world's remaining conventional oil is estimated to lie in carbonate
reservoirs, the need to better understand carbonate production capabilities. The objective of this
research is to studies the effects on dissolution rates of carbonate by varying the geochemical
conditions.
Acid dissolution is one of the important parameters that can affect the porosity and the
stability of the rock. Two different samples of carbonate have been selected to complete this
project and collected from Sg. Siput (limestone) and Simpang Pulai Quary (marble). The
problem statement, objectives and scope of study will also being discussed in Chapter 1 of this
paper. The literature review about carbonate rock has been discussed in Chapter 2.
In Chapter 3, it is about the methodology to be applied in measuring the important
parameters of the samples. It focuses more on lab activities such as core sampling, thin section,
Microscopy Polarization Image, XRD (X-ray Diffraction), XRF (X-ray Fluorescence), Field
Emission Scanning Electron Microscope (FESEM), Thermal Conductivity, Acid Dissolution
Experiment and Mercury Porosity Test.
Next, the results of both the test and experiment are discussed in Chapter 4 with the
relevant tables and graphs followed by conclusions or summary. At the end, the author cited lists
of references and few appendixes.
