During my training a couple of approaches were assigned to me such as calculating the porosity and permeability using different instruments for example DHP (Digital Helium Porosimeter) and DGP (Digital Gas Porosimeter) also VINCI which is used for unsteady-state processes, how inject mercury to samples and calculating the bulk volume of the sample using Archimedes law, CT scan which include several software’s for making videos of core sample to analyze the fractures and how it will affect the value of porosity and permeability, Formation Resistivity Factor ( capillary pressure) (appendix 2), permeability of fluids, flush cleaning using different solvents, and finally the dean stark which is about extraction of oil and water.

Consequently, the first week of training was about introduction to the company programs and services as well as the devices and process used in the laboratory.
Second week I started with the first task in CCA section which required the measurement of porosity by using DHP device (figure1). This task contain all the impotent measurements and calculation in porosity by using Boyle’s law (appendix, 1), also exporting the data in excel sheet to determine the capacity of core to hold fluids, and analyze the graphs with different behaviors (figure 1, appendix 2). Besides that, I also get a chance to use the VINCI device (figure 2) which is used for unsteady state process to get knowledge in how to determine several parameters in more accurate way such as porosity, permeability, pore volume, and bulk volume by sitting the pressure.

Moreover, the instrument calculate the pore volume and porosity by using the ideal gas law, also the pressure applied to the core is generated by high accurate hydraulic pump.
Nevertheless, in the same week I worked using DGP device (figure 3) which is specific for permeability measurement. The main factor of permeability is Darcy law (appendix 1), the important parameters of Darcy

Recommendations
The lectures are presented in white bored without any other materials which could help the person to understand in better way. I have found during the lecture that some workers found difficulties in understanding the main idea of the topic.
In my point of view, the lectures could be presented in an interesting way if the presenter use some other materials behind white bored for example pictures, power point, graphs, and videos related to the topics.
5.3 Radiation test of CT scan
Radiation test of CT scan is performed to determine the amount of radioactive waves emitted from CT scan. This test is an essential for all the workers inside the laboratory due to the harmful emitted waves.
The test done by the lab engineer using a special device that measures the emission of radiation waves.

Recommendations
I have noted during the test that some works do not have enough idea about the risks of radiation waves and they do not wear a special lab costume that prevent them.
My own feeling on the subject is that there should be some rules and actions taken by the responsible person in order to maintain the safety of employees also educate the staffs about the risks of radiation waves.
5.4 Oil spill
The department safety manager performed a task of Oil spill, the oil was spilled on the ground without informing any of the workers in order to test the ability of employees in dealing with various safety situations.What’s more, the manager discus around the safety issues as well as the accidents that can be cussed by oil spill and the correct way of how to deal with similar situations in future.
Recommendations
The task was completed in a useful way and improve the workers knowledge about safety in the work place.
In contrast, while running the task the safety equipment was not found in the proper place also some workers do not have a complete idea of using the equipment.
In my opinion, the department should assign some workers to check the safety gear monthly also place it in its proper place to avoid any misbehaver.
