Saphir NL; Pressure Transient Analysis Pressure Transient Analysis, or PTA, is, in most cases, about analyzing high frequency, high resolution shut-in data. The data are captured during dedicated well test operations such as DSTs or production tests or during routine operational shut-ins by Permane ...

Rate Transient Analysis, or RTA, is the natural complement to Pressure Transient Analysis (PTA) when one has pressure and rate data.# RTA can be used to increase the area of investigation when compared to using PTA alone. Advancements in RTA have progressed partly due to the development of permanent ...

Rubis is a 3D, 3 phase, multi purpose numerical modeler which sits somewhere between single cell material balance and massive full-field simulation models. It replaces neither, but does much of the work of both. One can build simple numerical models intuitively with no special training. The geometry ...

Production logs, or PLs, are run on production or injection wells, with the goal of evaluating the well itself and/or the reservoir performance. Put simply, for producing wells, we need to determine what fluid is coming from which zone, and how much. The PL string may be a relatively simple, convent ...

Field Performance Analyis often involves analyzing hundreds, sometimes thousands of multifractured horizontal wells with low resolution data. But the demands on engineers remain the same, to analyse these wells and to provide regular forecasts, reserves and performance optimization. With such massiv ...

Formation testing, or FT, has many applications including formation fluid characterization, pressure measurements and reservoir characterization. Pressure data can be analyzed as it varies with depth. Multiple pressure measurements are taken in the well to determine fluid density gradients and poten ...

Amethyste is a standalone module dedicated to Well Performance Analysis. It has its technical roots in WAM, a tried and tested WPA program developed and used by Marathon since 1986. It spans the divide between data and datum in Saphir NL, Topaze NL and Rubis and provides a natural extension to resul ...

Permanent Downhole Gauges (PDG) are a remarkable source of information of both long term production data and the capture of occasional buildups that may be described as ‘free well tests’. Data are acquired at high frequency and over a long duration. The down side is the large number of data points g ...

CoreHD® Plus: Achieve greater impact from whole core data with additional petrophysical curves CoreHD® Plus begins with spectral gamma logging and XRF (X-ray fluorescence) measurements on the whole core. This data, combined with RhoB and PEF, is used to compute the additional curves. Ingrain uses d ...
