Paper presented at the Annual Technical Meeting, June 6–8, 1995
Paper Number: PETSOC-95-12
... Abstract An analytical composite model using non-linear least square regression technique for estimation of real parameters of naturally fractured reservoirs, utilizing well test data is presented. The problem of alteration of fracture properties due to acidizing or damage called by drilling...

... Abstract Dilation, or increased pore volume caused by multiple shear parting tangentially off a created vertical tensile fracture, is estimated using fall-off data from a minifrac test performed on a McMurray formation oil sands well at a depth of 300 m. For an assumed fracture height of 16 m...

... as a good representation of the "true" values. The effect of errors in the reservoir pressure measurements on the Havlena-Odeh 4 method are examined using a gas cap drive reservoir as an example. The errors in the measured pressures are estimated from the available data. These errors are propagated...

... by the extend of reservoir depletion, number of data points, and data collection frequency. This work analyzes the effects of errors in the input data on reserve estimation via a graphical material balance analysis based on a straight line to study the value of additional and/or accurate data acquisition...

..., is proposed. Rather than relying on soil monitoring to indicate the beginning of an irreversible pH drop, the new method allows the time of this occurrence to be calculated if the mean SO 2 or sulphur deposition rate is known or can be estimated. It is also possible, in atleast some cases, to identify...

... method 2 for calculating the static pressure. The calculation of both P gc and P ic requires the information on gas and liquid columns lengths variation in time. The method widely used in industry to track the gas-liquid interface is the acoustic well sounding technique (AWS). The estimation...

... of mass balance of gas phase in the annulus may be used to estimate annular gas rate and flowing bottomhole pressure of a pumping oil- well. The method enables one to calculate the ann- ular gas volume, including gas bubbles in the oil column. The knowledge of annular gas volume can then be used to find...
