Phase Behavior in Petroleum Fluids: a Detailed Descriptive and Illustrative Account with Emphasis on Heavy Organics

An improvement in RTM method to image steep dip petroleum bearing structures and its superiority to other methods

In this paper, first the limitations of the ray-based method and the one-way wave-field extrapolation migration (WEM) in imaging steeply dipping structures are discussed by some examples. Then a new method of the reverse time migration (RTM), used in imaging such complex structures is presented. The proposed method uses a new wave-field extrapolator called the Leapfrog-Rapid Expansion Method (L...

Activated carbons prepared from thermally and chemically treated petroleum and coal tar pitches

Petroleum and coal tar pitches have been treated thermally at 4008C and 4708C, extracted with toluene and subsequently activated with CO at 9008C. With one exception, the development of the micropore widths and volumes in the resulting 2 carbons follows the trend observed for carbons based essentially on precursors of vegetable origin. On the other hand, petroleum pitch treated at 4008C leads t...

Production of Mesophase Pitch from Coal Tar and Petroleum Pitches using Supercritical Fluid Extraction

Supercritical fluid extraction (SFE) is currently being investigated as a possible technique in the production of high quality mesophase pitch from coal tar and petroleum pitches. Mesophase pitch is used to make high technology products, such as carbon fibre. The conventional production of mesophase pitch initially involves the removal of low molecular weight species from coal tar and petroleum...
