In the usual geostatistical practice, global estimation of a deposits is made by running the estimated values obtained by kriging for each individual block in the deposits. When all blocks are identical in size it is equivalent to simply accepting the average of all the estimated values as the global estimated value. Variance of this estimator is expressed by a complicated formula. This explain…
The assumption of lognormal (parent) field size distributions has for a long time been applied to resources apprasisal and evaluation of exploration strategy by the petroleoum industry. However, frequency ditributions estimated with observed data and used to justify this hypotesis are conditional. Eximination of various observed field size distributions across basins and over time shows that su…
A feedback or validation procedure is an essential feature of petroleum resource evaluation methodology. The purpose of such a procedure is to provide assessors with a mechanism which enables them to validate input data and challenge geological interpretations. In our method, pool sizes can be estimated by rank from the pool size distribution and the number of pools of a play (Lee and Wang, 198…
Early microscopic examination of coals and coal macerals began with the use of transmitted and then reflected light microscopy. These methods were limited by the resolution and optical quality of the microscopes used. Improved microscope technology and the development of oil immersion techniques led to advancements in coal petrology. Introduction of the atomic force microscope (AFM) has led to …
The regional Remote sensing Programme (UNDP/RAS/86/141) was initiated in March 1983 and is a project of the governments of Asia and Pacific.
