INTRODUCTION. The California Department of Conservation, Division of Oil, Gas, and Geothermal Resources (DOGGR), and the US Bureau of Land Management (BLM) receive monthly production, injection, and related data from operators of oil, gas, and geothermal xxxxx in California. Most of these data are non- confidential and available through the DOGGR website (xxxx://xxx.xxxxxxxxxxxx.xx.xxx/). For data visualization, very powerful Microsoft Excel based tools have been developed that may either be used directly or easily modified to fit individual needs. They may be used to: 1) easily organize and retrieve data-groups, 2) reduce large data sets to meaningful sizes, and 3) graphically present the data. With the help of these tools the user can quickly and easily review data in many different ways. Data trends, as well as discrepancies, become more visible and easier to discern. In Figure 1, field-wide average production and average wellhead pressure, reduced at a rate of 6:1, are plotted. There are just too many points to interpret. However, when the same data are “appropriately reduced,” in this case 1050:1, (Figure 2) a clear trend and useful information emerges (details are discussed in section 6.1).
