New Rock Eval-6 analyser:-


The rock eval pyrolysis is a source rock screening tool that measure the concentration of free hydrocarbons in the rock sample (S1) , the residual hydrocarbons in the kerogen disseminated in the rock sample (S2) and provides an estimate of the maturity of the rock sample (Tmax). Analysis is done on ground rock samples according to a programmed temperature pattern and the quantity of evolved hydrocarbons and CO2 are monitored as a function of increasing temperature .From complentary stage allows determination of Total Organic Carbon (TOC) and Mineral Carbon (MINC) content of samples.

 2- Inorganic Geochemical Analysis:


  •  Determination of the major elements: (Silicon, Ignition loss and Aluminum, Iron, Magnesium, Sodium, Potassium, Titanium and Phosphorus).
  •  Determination of trace elements (Vanadium, Chromium and Cobalt, and strontium).
  •  Determination of the mineral composition of the clay fraction and other rock by using X-ray diffraction method.


3- Petrographic Studies:


  • Study the mineralogical composition of the rocks (sedimentary rocks), its percentage; matrix and cement; roundness; cementation, sorting, and other micro-sedimentary structures
  • Degree of diagenesis i.e. aggregation, degradation pressure solution and other environmental effects on the history of deposition. In addition, using SEM to assist to great extent in this study.
  • Petrophysical  studies of rock  i.e.types of porosity, permeapility
  • Determine the rock name of the investigated rock.


Interpretating the geological history of the recorded depositional environments, sequences of deposition i.e. river; marine; lacustrine; lagoonal; beach; . . . . . . etc



The geophysical laboratory of  the Egyptian Petroleum Institute has the ability to conduct the following disciplines:-

 

I- Potential field Data Interpretation:


            This involves gravity and magnetic data, as shown as follows:

 

A-Gravity:

 

The interpretation of the available Bouguer gravity anomaly map of the study area comprises the following items:


1-Residual-Regional Separation:


To isolate the significant shallower and smaller structural-stratigraphic elements of interest from the insignificant deeper and wider structural- tectonic features.

2- Gravity Spectral Analysis:


            To subdivide the invistigated sedimentary section into sequences of varying physical and lithologic characteristics and to define the depths of their discontinuities.

 

3- Two and Three- Dimentional Gravity Modelling:

 
To delineate the structural elements through the trends of more structural complexity and to map such elements on the tops of the interesting units.

B- Magnetic:


The interpretation of the given total intensity aeromagnetic map of the study area consists of the following topics:

 

1- Reduction To the Magnetic Pole:


To eliminate the distortion occurred in the existed magnetic anomalies due to the inclination of the measured normal magnetic field.

 2- Magnetic Frequency Filtering:

 

To subdivide the responsed magnetic anomalies into categories of varying depth intervals according to the utilized frequency ranges of the filter operators band paths.

3- Two and Three Dimentional Magnetic Modelling:


To con figurate the basement features, with special reference to the implicated dyke system, whether they are intra-basement or supra-basement.

II-Seismic Prospection :


The interpretation of the available horizontal seismic profiling data of the considered area includes the following versions:


 1-Velocity Analysis

 

To determine the different types of velocities of the studied section with their applications in the seismic reflectivities of the lithologic discontinuities and as hydrocarbon indicators.

2-Seismo - Tectonics:


To map the various structural elements ( anticlinal and synclinal folds, as well as dip- slip and strike- slip faults) capping the seismic tops and the genetic aspects standing behind them.

 

3- Seismic- stratigraphy:


To delineate the seismic reflection characteristics of the stratigraphic units, their iso time layer cakes, their lithofacies, their depositional environments and their sedimentational model.

4- Areal evaluation:

 

To test the suitability of the studied area to be a promising productive area, based on the optimum location of the needed wells and the establishment of their proposals.

 Such a study, based on the open- hole log data, comprises the following topics:

 

1-      Formation evaluation:


To carry out the needed environmental corrections, then to calculate the formation porosities and the fluid saturations, with the presentation of porosity­  saturations, crossplots.

 

2- Reservoir Analysis:


To determine the formation permeabilities, reducible and irreducible water saturations, water cuts, net pays, oil in- place, oil reservoir, recoverable oil and reservoir quality.

3-Lithology Make- Up Modelling:

 

             To discriminate the minerals forming the groups (silicates, clays, carbonates, evaporites, basement complex and mixed lithology) through the establishment of the mineralogic- lithologic models.

The lab is specialized in the field of:

 
  • Biostratigraphy and geochronology by means of: Foraminifera, calcareous Nannofossils and palynomorphs (palynology). lo Photographing the index studied fauna and flora by means of a group of modern microscopes providing with digital cameras.
 
  • Reconstruction of sedimentary environments (Paleoenvironment).
  • Estimation of paleotemperature.
 
  • Describing paleoclimates.
 
  • Paleogeography.
 
  • Sequence stratigraphy (cyclostratigraphy).
 
  • Integrate Biostratigraphy with other corporate sources of geosciences data (wireline logs and graphic lithology).
 
  • Produce the following by means of the StrataBugs

software:

 
    • Lithologic charts.
 
    • Range and distribution charts.
 
    • Biostratigraphic events (appearance and disappearance).
 
    • Correlation charts.
 
    • Frequency, diversity, P/B %, A/C % and dominance of species charts with   quantitative occurrence in digital or symbol display.
 
    • Sea level and depth change curves.
