Paper presented at the SPE Trinidad and Tobago Section Energy Resources Conference, June 25–26, 2018
Paper Number: SPE-191160-MS
... Abstract Forecasting future production and estimating ultimate recovery (EUR) in supertight reservoirs and shale plays has long been problematic. Developing a reliable and more accurate production forecast have always been a main goal of any petroleum operation. Effectively assessing...

Paper presented at the SPE Trinidad and Tobago Section Energy Resources Conference, June 25–26, 2018
Paper Number: SPE-191178-MS
...: Well monitoring for progressive cavity pumps (PCPs): This workflow tackles the early detection of anomalies in operational variables for well performance. Well rate estimation for PCPs: This workflow calculates production rate estimates for PCP wells. Well status: This workflow provides the live...

Paper presented at the SPE Trinidad and Tobago Section Energy Resources Conference, June 25–26, 2018
Paper Number: SPE-191224-MS
... Abstract Although various novel techniques were developed in reservoir engineering for estimation of hydrocarbons initially in place (HCIIP), conventional material balance still remains as one of the most reliable. Average reservoir pressure is critical input data for material balance, which...

Paper presented at the SPE Trinidad and Tobago Section Energy Resources Conference, June 13–15, 2016
Paper Number: SPE-180857-MS
... Abstract A variety of correlations for the estimation of CO 2 Minimum Miscibility Pressure (MMP) have been proposed. Although some of them are less accurate, the correlations are helpful in roughly screening a candidate reservoir for CO 2 flooding and in designing CO 2 parameters without...

Paper presented at the SPE Energy Resources Conference, June 9–11, 2014
Paper Number: SPE-169989-MS
... Figure 1 Key elements for reserves estimation There are differences among these methods due to the approach which were generated, each of them require specific information and normally a common practice is to use the result of the volumetric method as first option before any...

... temperature data by means of sensitivity analysis. To estimate the hydraulic fracture characteristics, we employ the ensemble Kalman filter (EnKF), an ensemble based sequential model updating method, to assimilate DTS data. The EnKF enables us to perform quantitative fracture characterization and automatic...

Paper presented at the SPETT 2012 Energy Conference and Exhibition, June 11–13, 2012
Paper Number: SPE-156278-MS
... Abstract In the present work, an attempt has been made to develop a simple-to-use method to estimate shape-related skin factor for horizontal wells centrally located within square and rectangular drainage areas. The results can be used in follow-up calculations for rapid estimating the pseudo...

Paper presented at the SPETT 2012 Energy Conference and Exhibition, June 11–13, 2012
Paper Number: SPE-158548-MS
... Abstract Pore pressure studies have been a key consideration in well design; both from a drilling design and well deliverability perspective. In the drilling of an exploration opportunity, and in the absence of direct pressure measurements, pore pressure estimation becomes even more critical...

Paper presented at the SPETT 2012 Energy Conference and Exhibition, June 11–13, 2012
Paper Number: SPE-158805-MS
... Abstract Reservoir fluid properties such as bubble point pressure, oil formation volume factor and solution gas-oil ratio are used for the evaluation of reservoir performance and reserves estimation. Laboratory analyses of these properties are not always available and they are best estimated...

... including crude oil production, processing, transportation and refining. In this paper, an attempt has been made to formulate a simple-to-use method which is easier than existing approaches, less complicated and with fewer computations for accurate and rapid estimation of crude oil salinity as a function...

Paper presented at the Trinidad and Tobago Energy Resources Conference, June 27–30, 2010
Paper Number: SPE-132403-MS
.... In this work, a novel and simple predictive tool is presented to estimate the formation of calcium carbonate scaling as a function of pH, temperature, ionic strength of the solution, calcium cation concentration, bicarbonate anion concentration and carbon dioxide mole fraction when the water mixture...

... conditions. Such typecurves are generally used for predicting reserves and future production rates as well as reservoir parameters. Although simplifying assumptions used in deriving such curves might imply their applicability to some certain conditions, but still a very good estimation of reservoir...
