Scientific Articles

AAPG suez has made a collection of scientific articles about petroleum field as general which we believe it will be very important to know about them as they would help establish the basics of this field.

Deformation Of Sedimentary Rocks


Break, transport then rest is the right description of these three geological events. Rocks are broken down and chemically dissolved through weathering .this occurs when rocks are subjected to the atmosphere and ocean bottom. Rivers, wind, waves, gravity....

Carbon Dioxide Enhanced Oil Recovery


Under suitable reservoir pressure at a depth generally greater than 1200m and oil gravityless than 22° API gravity, injected carbon dioxide will mix thoroughly with the oil within the reservoir such that the interfacial tension between....

HSE-INTRO


Your main goal at the oil field is to keep yourself safe and health. HSE-knowledge can help you to achieve this. If it is your first time to hear about HSE, it refers to “health, safety and environment” which they are indispensable for anyone who...

Abnormal pore pressure


Pressure is one of the main concepts for a petroleum engineer because it affects every decision he takes in every stage of well life. Hydrostatic, overburden, pore pressure are the main types of pressure but we’ll concentrate on pore pressure especially ...

Directional Drilling

Many problems such as fishing, restricted surface location, salt domes and water coning are faced during drilling in addition to, weakening of oil prices and the need of reducing drilling costs. A suitable way to overcome these dilemmas is to use ...

Petroleum Migration


A source rock is a rock that can generate natural gas and/or crude oil. As sediments are deposited, both inorganic mineral grains, such as sands and mud, and organic matter (dead plants and animals) are mixed.The black color...

Cementing Job

Have you ever asked yourself why we do cementing job? Well, cement is very important in well drilling as it provides a good protection for your well and environment. Cement provides a good isolation for your well preventing fluids from travelling out and in the well. As it makes zonal isolation in which no fluid migration up or down, preventing...

4D Seismic Surveying

Seismic surveying can be limited to two dimensions:length and width, three dimensions:length,width and height and four dimensions:length,width ,height and time. The last one is called: 4D seismic surveying or time-lapse surveying.The objective is to determine the changes occurring in the reservoir as...

A Deviation In The Deviation

This equation "PV=nRT" is one of the most important equations in petroleum engineering, it is simply the ideal gas law, we use it to calculate amount of gas production in gas reservoirs, but is the gas really ideal?

Contracts Regulations

Imagine that you are an operator of oil company..
After looking at possible places where we drill our first wildcat well based on data we gathered, processed and interrupted Having located some interesting possibilities in the exploration of sedimentary basins, it's now time for you

Differential Pipe Sticking

A stuck pipe is a common worldwide drilling problem in terms of time and financial cost. It leads to significant increase in non-productive time and losses of million dollars each year in the petroleum industry. There are many factors affecting stuck pipe occurrence.

3D Seismic Surveying

Oil and gas exploration needs information from many sources: well logging, geological reports, geophysical methods...Etc. From the geophysical methods: 2D, 3D and 4D surveying according to dimensions we are dealing with.

Distillation

Distillation is a physical process of separating the component substances from a liquid mixture based on differences in the boiling point of the components of the mixture. There are many types of distillation..

Petroleum Traps

Trap is a place where oil and gas are barred from further movement. The word trap was first applied to a hydrocarbon accumulation by Orton ( 1889 ). A trap may contain oil, gas or both depending on

Well control

The term well control refers to the control of downhole formation pressures penetrated by the well. There are three distinct well control levels that may occur during drilling operations

  • Primary
  • Secondary
  • Tertiary
