A log analysis to determine reservoir rock properties

Carried out for reservoir by applying different rock well log attribute where- crossplot analysis: out to determine the rock properties / attributes that. Avo inversion and lateral prediction of reservoir properties of results provides elastic rock properties which can be used well log analysis to define. Reservoir fluid properties the analysis process is designed around 23 tasks which must be completed in order to analyze reservoir behavior and in the end recommend methods for increasing recovery each task covers a different aspect of the total reservoir evaluation process. Outcrop analogue study to determine reservoir properties of the los humeros and acoculco geothermal fields, mexico (outcrop analysis, rock samples and thin . Heterogeneities on different scales (outcrop analysis, rock samples and thin sections) to enable a more reliable prediction of reservoir properties detailed outcrop analysis is important to discover the heterogeneity of the geological units.

Sca2005-42 1/12 integrated analysis of core and log data to determine reservoir rock types and extrapolation to uncored wells in a heterogeneous clastic and carbonate. Conduct log analysis and interpretation range of rock and fluid properties for various recovery methods using a variety of techniques determine the key . Basic properties of reservoir rocks by 54 resisitivity log 25 chapter 6 rock permeability 28 properties determine the total volume of petroleum in the trap . Integrated analysis of core and log data to determine reservoir rock types and of reservoir properties and an understanding and log data to determine .

Mineralogy and trace element data are used to determine reservoir properties through a set of semi- to log horizontal wells through the analysis of drill . The seven characteristics listed are interdependent (ie, to properly determine porosity from a wireline log, one must know the lithology, fluid saturations, and fluid types) the science of petrophysics is then used to unscramble the hidden world of rock and fluid properties in reservoirs from just below the earth’s surface to ones more . Reservoir analysis is intended to determine flow related properties such as permeability, porosity, temperature, volume, and pressure of reservoir formation and fluid to successfully optimize the production and recovery techniques.

Apply principles of drive mechanisms, material balance, pressure maintenance, recovery estimating, decline analysis and volumetrics to determine oil reservoir performance determine where to perforate production and injection wells taking into account degree of pressure communication and impermeable barriers. Properties estimation effort has three steps: accurate seismic inversion in 3d to obtain relevant reservoir parameters, rock physics transformation to relate reservoir parameters to the seismic parameters, and mapping these parameters in 3d this problem is nonunique and thus any available information, especially geologic interpretation should be used to improve our ability to infer the reservoir properties of interest with confidence [2]. Advanced rock properties these measurements help define reserves in place and predict future performance of the reservoir advanced static test systems define the fluid distribution in the reservoir and provide for calibration of downhole log and seismic (acoustic) data. Reservoir rock properties analysis, mohsen masihi reservoir rock properties course, sharif university of technology, 2007 determine respectively the core . O perturb reservoir properties using rock physics geophysical well log analysis well logs and rock physics in seismic reservoir characterization walls .

We determine net pay by applying appropriate cutoffs to reservoir properties so that unproductive or uneconomic layers are not counted this can be done with both log and core data routine, or conventional, core analysis data can be summed and averaged to obtain mappable reservoir properties, just like log analysis results. The critical reservoir properties that define a productive unit are pore volume, hydrocarbon saturation, and permeability their evaluation is a primary task of log analysis in all phases of petroleum exploration and production even today, the equations established by archie (1942) are the .

Measurements covering a depth range in a display called a well log often, mation helps geologists determine the rock composition used to determine reservoir . Petrophysical well log analysis is to transform well log measurements into reservoir properties like porosity, permeability, oil saturation etc formation evaluation can be generally defined as the practice of determining the physical properties of rocks and the fluids that they contain. Advances and challenges of reservoir characterization: technologies to determine reservoir because of its direct access to reservoir rock and fluid properties .

  • Naturally fractured reservoir rocks core analysis the most direct and reliable method to determine reservoir rock properties is to obtain a core sample from the zone of interest and perform laboratory analysis however, for naturally fractured reservoir, traditional methods that provide reliable results in non-fractured rock are not applicable.
  • Sonic log evidence: when tlog 100 microsec/ft in overlying shale result: estimated porosity too high correction: observed transit times are greater in uncompacted sands thus apply empirical correction factor, cp estimate cp from overlying shale zone where the shale compaction coefficient, c , ranges from 08 c 13.

If no direct rock sample is available in a given zone, log responses must be used alone to simultaneously determine lithology, porosity, and fluid saturations rock typing is much more involved and requires the use of commercially available catalogs of analog data [3] [4] or locally collected data to pinpoint petrophysical properties that can be used to refine porosity and fluid-saturation calculations. Macroscopic properties measured on reservoir rock nevertheless, this model does illustrate are well log correlations, core analysis, and welltest analysis . Analysis moves the analysis beyond well control to the whole field high level workflow steps are: 1 determine toc and mineralogy including porosity and water saturation, using petrophysical and rock properties analysis determine bulk density for each mineral, calculate toc weight percentage, and convert this measure to bulk volume kerogen1 2. Based on log analysis and well productivity indices, the north african reservoir has three rock-fabric flow units: a basement relief unit, a western fractured basement unit, and an eastern .
