Petrophysics and Geophysics have not always worked in the past as closely together as one might expect. This paper discusses current advances, and sketches future developments. The major objective of Geophysical Research was to obtain sharper pictures. With the advent of 3-D seismic, there is a strong trend to make displays both in time and depth, and to convert seismic attributes into rock pro...

The characterization of fluid-transport properties of rocks is one of the most important, yet difficult, challenges of reservoir geophysics, but is essential for optimal development of hydrocarbon and geothermal reservoirs. Production of shale oil, shale gas, heavy oil and geothermal energy, as well as carbon-dioxide sequestration, are relatively recent developments where borehole fluid injecti...

Geophysical measurements increasingly are being used in hydrologic field stud-­­ ies because of their ability to provide high-­­resolution images of the subsurface. In particular, tomographic imaging methods can produce maps of physical property distributions that have significant potential to improve subsurface characteriza-­­ tion and enhance monitoring of hydrologic processes. In the tomogra...

Abstract Hydrocarbons exist in abundant quantity beneath the earth's surface. These hydrocarbons are generally classified as conventional and unconventional depending upon their nature, geology, exploitation procedure. Since under depletion phase, have been a major candidate for current future hydrocarbon production. Additionally, investment research increased significantly its exploitation. Ha...

This work represents study the rock facies and flow unit classification for Mishrif carbonate reservoir in Buzurgan oil Field, which located n south eastern Iraq, using wire line logs, core samples petrophysical data (log porosity permeability). Hydraulic units were identified zone indicator approach assessed within each type to reach better understanding of controlling role pore types geometry...

The X Formation, which dates from the Late Cenomanian to early Turonian, is largest carbonate reservoir in Iraq's South Mesopotamian Basin. There are two shallowing-up depositional periods it, begin with deep water mudstone associated wackestone, gradually shallows into rudist and dominated by big foraminifera shoals barriers, followed lagoonal intertidal facies. identification of five distinct...
