In 1987, Baker International and Hughes Tool Company merged and Baker Hughes Incorporated was conceived. Baker Hughes Incorporated is one of the world's largest oilfield services companies. Operations of Baker Hughes are carried out in over 90 countries all over the world having its main headquarters in the America Tower in Houston. Services provided by Baker Hughes are for drilling, completion, reservoir consulting, formation evaluation, production and unconventional solutions.
Baker Hughes's operations are divided into 2 Hemispheres; Eastern Hemisphere (Europe, Africa, Middle East, Asia Pacific & Russia/Caspian) and Western Hemisphere (Canada, US Land, US Gulf & Latin America). Furthermore, each of these Regions is subdivided into Geo Markets.

Sample is slowly and carefully placed on the mixture to avoid air bubbles.
Sample is clamped for 24 hours to allow it to stick.
Sample is removed and is now grinded down to 30 m to become translucent and therefore become visible under microscope.
5.2.2 Preparation of a dyed sample
Sample is cleaned and cut into a square of size 2X2 cm.
Dye is prepared using 95 mg epoxy Resin, 0.3 mg blue Dye, 12.5 ml thickener, 12.5 ml thinner
Epoxy and hardener mixture is prepared (used to glue samples to the glass slides). Mixture - 4 mg epoxy and 1 mg hardener.
Sample is placed in a container and is placed in vacuum to remove air bubbles.
Dye is poured into the vacuum container by as syringe.
Sample is left for 15 minutes.
Sample is removed and placed in a nitrogen gas pressure vessel for 24 hours at 1000 psi.
Sample removed and again cut into 2X2 cm.
Epoxy and hardener mixture is prepared (used to glue samples to the glass slides). Mixture - 4 mg epoxy and 1 mg hardener.
Mixture is stirred for 10 minutes and placed in an oven for 2 minutes at 45°C.
Mixture taken out from the oven and poured on the glass slide.
Sample is slowly and carefully placed on the mixture to avoid air

It is this stage which guides us to select precise areas to produce from. After the presence of hydrocarbon is confirmed, we enter into the appraisal stage. This stage involves drilling a couple of wells in different locations to determine the extent of the reservoir and further explore the options of production. A series of logs are run both during and after drilling (LWD and wireline respectively).
Log such as SP (spontaneous potential), GR (gamma ray), density and resistivity are very helpful in making a reservoir model. After a reservoir model is made we can get the whole idea of the reservoir. Various criteria’s are looked at to select an area to produce from. Some of the criteria’s are as follows:
Porosity : higher preferred
Permeability : higher preferred
Type of formation : sandstone or carbonate (cleaner preferred)
Hydrocarbon saturation : higher preferred
Water cut : lower preferred
Thus, it is very important to begin searching for hydrocarbon at a place which could be suitable for its existence. It could take months of research to find a suitable play area. Selecting a zone could be difficult if the reservoir model is not accurate and could even lead to a bad
