.... Matthews suggested plotting p and using an average slope and average gas properties. This method was more successful on high pressure wells. Al-Hussainy, Ramey and Crawford showed that variation in gas properties could be simplified by using the real gas pseudo-pressure m(p). Some cases showed that the use...

...A.J. Pearson PEARSON, A.J., CONTINENTAL ILLINOIS NATIONAL BANK AND TRUST CO. CHICAGO, ILL. MEMBER AIME Introduction Banks have been loaning money secured by oil and gas properties since 1928.

... methods that have not been heretofore presented, or at least have not been widely circulated in the literature of this subject. The fundamentals of this art or science or business of appraising gas properties have been presented by many writers. To avoid the necessity of reviewing and restating the basic...

...Ralph E. Davis; Eugene A. Stephenson The appraisal of natural gas properties is a complex problem affected bymany non-engineering factors. Attention will be brought here to the moreimportant matters that influence value of such properties, such as thenecessity of competent estimates of reserves...
