Water Tests to Analyze Water Quality: 
PH: Power "Potenz" of Hydrogen.
ISE: Ion-Selective Electrodes.
ORP: Oxidation Reduction Potential.
EC: Electrical Conductivity.
TDS: Total Dissolved Solids.
SS: Solved Solids.
DO: Dissolved Oxygen.
TEMP: Temperature.
COD: Chemical Oxygen Demand analysis by two different methods:
1- CODCr: the dichromate method.
2- TiO2/UV: photoelectrochemistry (the PeCOD™ method). Color, Turbidity, Salinity, CL-, PO4, NH3,NO3 and etc.

• TDS = keEC (ppm or mg/L), The correlation factor ke varies between (0.4 - 1.0) (default value for AD332: 0.5)
• Salinity was based on chloride concentration: S = 1.80655*Cl

• TDS meters can be used to test for Salt (up to the maximum range of the meter). Salt is a part of Total Dissolved Solids and therefore will be part or all of the reading. If you are first filtering the water, and then adding salt, simply use the meter as you would under any circumstances. If there is only salt in the water, and the reading is 2500 ppm, then the it is 2500 ppm (mg/L) of salt.

Conductivity, Salinity & Total Dissolved Solids

• The USA, Environmental Protection Agency (EPA), the World Health Organization (WHO) and most nations put maximum limitations on TDS allowed in drinking water from 500 to 1000 ppm.

• If you drink 1 liter of water a day, your body will have processed 25567 liter of water over a 70 year span. If the water is not totally pure, this 25567 liter will include (20 - 30) Pound of rock that the body cannot utilize. Most will be eliminated through excretory channels. But some of this will stay in the body, causing stiffness in the joints, hardening of the arteries, kidney stones, gall stones and blockages of arteries, microscopic capillaries and other passages in which liquids flow through our entire body.

So that care about the water that you drink.

Cleaning of Water Wells by Air Compressor

تنفيض البئر أو تنظيف البئر - Cleaning of the well

فوائده:

• تسليك مسام الغلاف الحصوى حول البئر وترتيب الحصى مما يسبب فى رفع كفاءة البئر.

• تجرى هذه العملية بعد حفر البئر كما تجرى بعد ذلك لاحقا بغرض أعمال صيانة البئر والمحافظة على كفائتة.

• يتم تنظيف البئر عبر أغلاق فتحة البئر العلوية بغطاء ينفذ من خلاله هواء مضغوط بواسطة ضاغط للهواء (كومبروسر).

--------------------------------------------------

Benefits:

• Opening pores around the well casing and arrangement of the pebbles causing in raising the efficiency of the well.

• This operation is performed after the drilling of the well and then later for purpose of the well maintenance and preservation its efficiency.

• The well is cleaned by covering the upper aperture of well where compressed air pass through it by Air Compressor “Compressor”.

MOOC Oil and GAS: from Exploration to Distribution (IFP School)

Course Website: http://mooc.oil-and-gas.ifp-school.com

Objectives:

After successfully completing this course, participants will be able to:

• Describe the international energy scene and the issues at stake in the oil and gas industry – i.e. consumers, producers, main actors and prices.

• Describe the main processes and techniques of oil and gas exploration and production – i.e. geosciences, drilling and production – and describe their cost structure and their legal framework.

• Describe the main operations in refining, petrochemistry and gas processes and assess the diversity of products and the interactions between those three industries.

• Describe the specificities of the marketing and distribution of oil and gas and their products.
