... formations of similar age. This paper describes an evaluation sequence that includes the planning for LiDAR data collection, actual work and rock sample collection in outcrops, the interpretation and integration with geoscience in a 3D visualization room, and the potential for improved drilling...

... in 2006. In this paper, P-wave velocity (Vp) maps transformed from the seismic travel-time maps were interpreted with a new methodology for evaluating the areal extent of the steamchamber zone created by the SAGD process. In the previous experimental study of seismic velocity measurements with oilsands...

... quality is a critical and necessary step that must precede any interpretation of production data. Recognition of inconsistent data is not always an easy task, and requires a lot of experience. The diagnostics presented in this paper will help the engineer in recognizing these problems, and potentially...

... Abstract This paper presents an integrated workflow dedicated to the interpretation of 4D seismic data to monitor the steam chamber growth during the Steam-Assisted Gravity Drainage recovery process (SAGD). Superimposed to the reservoir heterogeneities of geological origin, many factors...

... was developed in 1987 as a hybrid system using analog filtering and recording of the acoustic signal 4,5 . Such system still depended in some measure on the operator's interpretation of the acoustic chart recordings to determine the average acoustic velocity in the annular gas. interpretation psia...

... techniques to recognize the different rock types and flow units through heterogeneous rock. Conventional log response and traditional log interpretation do not have the ability to discriminate the different rock types. So, discriminating between rock types and flow units through heterogeneous carbonate...

.... Considering all these assumptions, the total skin obtained from a well test interpretation is given by (Equation 1.) (Available in full paper) where S t , S p and S represents, respectively, the total skin obtained from the interpretation, the pseudoskin due to the partial completion and the mechanical skin...

... available for this field. Many features such as sealing faults, aquifer, fracturing and layering systems were observed during the well test interpretation. Some of the above features were identified only by pressure transient data such as one sealing fault in which it was not observed in the seismic data...

... Abstract The CAR-x1003 exploratory well, drilled in the Caranda field in 1997, proved to be a discovery well of the Robor? Formation. Test interpretation during completion was difficult because of high formation pressures and temperatures. In 2003, an additional test provided critical data...

.... It provides us with methods and ideas for designing, interpreting well tests and prediction of the long time performance of the system under study. A log-log plot of pressure and pressure derivative versus test time may reveal the presence of several straight lines corresponding to different flow regimes...

Interaction of the formation fluids with pore surfaces can significantly influence relaxation response hence, a good knowledge of reservoir geology and lithology is a requirement for interpretation in carbonate reservoirs...

The formulation of numerical model of interpretation in this software is based upon Tiab's Direct Synthesis, where the boundary conditions of the newly developed algorithm to fit pressure derivative is adapted...

... Abstract Forward modeling geosteering software allows a horizontal well to be geologically steered by determining the stratigraphic position of the drillstring. Using forward modeling software one is able to make interpretations to correctly land the well in the reservoir, maximize the pay...

Combining several production analysis methods in one application allows an analyst to build on the strengths of several...
