Usually imbibitions tests are conducted to obtain qualitative estimates of reservoir wettability and oil recovery. This paper presents a procedure for history matching of counter-current imbibitions tests that involves...

... are usually evaluated at the initial pressure level. Comparison of the analytical solutions with numerical solutions obtained for a variety of typical well test conditions indicates the magnitude of inaccuracy incurred by using standard approach to data interpretation. Based on this investigation, several...

... matching techniques of pressure and pressure derivative to determine several reservoir parameters are presented. Then, a new techniques, known as direct synthesis, for interpreting the pressure behavior of a horizontal well without type-curve matching is presented. Characteristic points are obtained...

... Abstract The Hibernia Field, located in about 80 metres of water, 315 km ESE of St. John's, Nfld., was discovered i" 1979. Of the 10 wells drilled, seven wells tested a 150 to 290 metre thick section of rock interpreted to have been deposited in a fluvio-deltaic environment. Located between...

... Abstract The main aim of well log interpretation is to determine the reservoir geological and petrophysical properties downhole as well as properties fluids and their distributions in a reservoir, and identification of hydrocarbon from well logs is the most important job. Neural networks...

... interpretation could be initiated. This model was refined until a reasonable match was obtained from the horizontal buildup data. Good agreement was achieved between the vertical and horizontal analyses. By utilizing this offsetting data set in the horizontal analysis, a better quality, higher confidence...

... of the problems for high permeability and porosity sandstone samples, in which the gravitational acceleration distorts the horizontal centrifugal force distribution inside core plugs and thus leads to inaccurate interpretation of capillary pressure information in the high saturation region. The possible remedial...

... Abstract This paper summarizes the analysis of wireline formation tester (WFT) data collected in tight gas sands. An interpretation algorithm based on type-curve matching is used in me analysis. The type curves are constructed using an analytical model. The model assumes hemispherical flow...

... Abstract Interpretive methods for the evaluation of miscible flood performance have been under considerable scrutiny over the last five years, It has been recently, shown that some of the more conventional procedures for miscibility determination might be inadequate for certain oil/solvent...

... but a reasonable p ∗. A longer shut-in does not correct the problem unless it is preceded by a longer flow period. The use of "equivalent time" to account for the short flow period introduces problems of its own. Introduction In most oil or gas well test interpretations, it is important to determine if the data...
