Exponential smoothing is a technique used to detect significant changes in data by considering the most recent data, whereas the moving average is a calculation to analyze data points by creating a series of averages of different subsets of the full data set. The advantage with exponential smoothing method over the moving average and weighted moving average is that it produces a forecast for one period ahead. Using the trend projection technique, forecasts for more periods ahead can be generated. The forecast is considered accurate as it accounts for the difference between actual projections and what actually occurred. Aggregate planning is the process of developing, analyzing, and maintaining a preliminary, approximate schedule of the overall operations of an organization. It attempts to balance capacity and demand in such a way that costs are minimized.
Special core analysis section are specialist in understanding petrophysical properties goes beyond special techniques with advance tests to help the client more in estimating their fields.
It is important to note however, that SCAl provide several services in MICP (mercury injection and capillary pressure), FRF (formation resistivity factor), and permeability of fluids especially water, CT scan, and flush cleaning using different solvents.
However, the department provides unique tests related to the above processes in order to ensure the delivery of good quality services and focus on saving costs to the customer.
Therefore, SCAL section is responsible for different fluid analysis at several stages in order to fulfil all the operational requirements and to achieve important results that optimize production and development of the fields.
Other sections
Weatherford laboratories also provide some other services behind the services provided by CCA and SCAL. These services include the basic experiments and requirement to observe several parameters such as temperature, pressure, and type of gas.
Summary of the internship
I have implemented the internship in Weatherford Company, Is one of the international oilfield services company. The company has several sections and the section where I had training is the Weatherford laboratory and is considered one of the main sections in Weatherford. The Weatherford labs are located in Ghala Industrial Estate in Oman.
The company offers internship opportunities to students in different departments for example wireline, product line which include laboratories, and finances related to their major and skills.
During the 6 weeks of the internship program, several tasks were assigned to me according to my major and practical skills in all the 3 units of laboratory department. I spend one week and several days in each unit with multi tasks given whereby some are related to my studies and others are for the purpose of gaining new experience in other fields that are semi-related.
Besides that, I was trained not only in improving my soft skills, but, also dealing with several safety situations in the workplace and management technique when dealing with others.

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
