this is a book of rev okorie that detailed the activities involved in testing to know the potencial , the producability or otherwise of a crude oil reservoir. this book also teaches the objectives of well testing, determination of reservoir drive,calculation of oil well production index, formular for calculating the various quantities of crude oil produced per day, the productivity index of the well, the skin factor of the well which is damage , vogels equation , measurement of oil and gas fractions , surface well testing equipment , gas oil ratio and the various reservoir environment and this is the second best selling of rev okorie books

this is the best selling of rev. okorie books containing all the nitigrities that a petroleum engineering student is required to know as far as petroleum engineering in the oil and gas industy is concerned, it contains in one book, so much information as seen in about ten , fifteen or twenty different engineering textbooks before you can get them , you will read only this one to get them.

As the name implies, this is a book by REV OKORIE, designed to contain in one piece all the necessary knowledge in petroleum engineering, ranging from elementary geology,exploratory techniques, well head operations, surface production activities, terminal operations and pipeline constructions. so this book will help you right from the geological depositions of hydrocarbon down to how it can be searched for and found, to how it can be extracted from the sub surface through the well head to the surface production facilities in the terminal, detailing the activities of the terminal,to purify the crude oil before their transmission through the pipeline to storage facilities or to the vessel at the high sea.

another text book by rev. okorie that teaches the detaild activities, involve in crude oil handling and movement in in the oil terminals. with detail calculations in terms of measurement of exact oil quantities in the different vessels used in conveying crude oil both on land and in the sea

this is a text book by rev. okorie that simplifies oil well testing opperation mainly in the area of oil well test modelling, qualitative and quantitative analysis. student of petrolum engineering would find it intresting and helpful in understanding oil well test operations
