Petroleum Equipment
CNPC is a global supplier of equipment and products for exploration, well drilling, well completion, acidizing fracturing, pipeline construction, surface construction work and offshore engineering. Equipment manufacturing is one of…
Radioactive Waste Material From Oil and Gas Drilling
Rocks in and around certain oil- and gas-bearing formations may contain natural radioactivity. Drilling through these rocks or bringing them to the surface can generate waste materials that contain radioactivity.…
Disadvantages of Petroleum
1. Petroleum is a limited resource Like all the other fossil fuels, petroleum represents a limited resource. Being used to produce fuels, different medicines, clothes, wax, vaseline, cosmetics and various…
How does the Repeat Formation Test (RFT) work?
How does the Repeat Formation Test (RFT) work? What is its objective? The repeat formation tester (RFT) tool was designed to measure formation pressure downhole via wireline. It measures pressure at specific…
Advantages of Petroleum
1. Is a resource that can be easily extracted from the underground reservoirs Today, the technology used to find new reservoirs and extract the petroleum located there has evolved pretty…
Resistivity and spontaneous (SP) logging
Resistivity logging is an important branch of well logging. Essentially, it is the recording, in uncased (or, recently, even cased) sections of a borehole, of the resistivities (or their reciprocals,…
Development petrophysics
Development petrophysics emphasizes the integration of core data with log data; the adjustment of core data, when required, to reservoir conditions; and the calibration and regression line-fitting of log data…
Role of petrophysicist
Petrophysics emphasizes those properties relating to the pore system and its fluid distribution and flow characteristics. These properties and their relationships are used to identify and evaluate: · Hydrocarbon reservoirs · Hydrocarbon…
Sperical Packed-Bed Reactors
Another advantage of spherical reactors is that they are the most economical shape for high pressures. As a first approximation we will assume that the fluid moves down through the…
Processes Affecting Crystals
The driving force for both the formation of new crystals and the growth of existing ones is supersaturation. This arises from the concentration of solute exceeding the equilibrium (saturation) solubility concentration.…
