Below are the field cases in which applied power was reported together with the oil production increase, so that we can evaluate and compare the energy gains of the different processes tested. Data reported by Gill[1] * Year: 1983 * Type of heating: distributed heating LF (60 Hz) * Depth of reservoir: 3,000 ft * Oil type: paraffinic and asphaltic, 11 API * Initial production: 0 B/D * Final production: 76 B/D with 150 kW applied and 10 B/D with 12 kW * Energy gain: 20 76/150 40 and 20 10/12 17. Data reported by Gill[1] * Year: 1983 * Type of heating: distributed heating LF (60 Hz) * Depth of reservoir: 2,800 ft * Oil type: paraffinic and asphaltic, 22 API * Initial production: 4 BOPD, 25 BWPD * Final production: 50 BOPD and 10 BWPD with 60 kW * Energy gain: 20 46/60 15. Data reported by Sresty[2] * Year: 1980 * Type of heating: distributed HF (5 to 20 kW at 13.56 MHz) applied to electrode systems inserted in the formation surface deposits (1 m3 excited) * Final production: 20 gal during a time not specified * Energy gain: cannot be computed. Data reported by Sresty[2] * Year: 1981 * Type of heating: distributed HF (40 to 75 kW at 13.56 MHz) applied to electrode systems inserted in the formation surface deposits (25 m3 excited) * Initial production: 0 * Final production: 8 bbl over a 20-day test period * Energy gain: 20 (8/20)/40 0.2.

Use of several types of production logs in combination can provide important information, often quite cost effectively, for diagnosing a gas kick encountered during drilling. An example is discussed below. During the coring of a gas sand at 15,000 ft, a pressure kick occurred, gas pressure was then lost at the surface, and mud was added periodically to keep the drillpipe full. On the day after the gas kick, noise and temperature logs were recorded during the same run inside the drillpipe with the well static. These logs were run to identify the flow path of a likely underground blowout.

Nuclear log interpretation is simply the practice of solving tool-response mixing-law equations with the judicious application of some assumptions and constraints. All interpretation is an approximate model. As more factors are taken into account, the interpretation usually improves, but the model becomes more complicated. For the neutron-porosity log, the simplest interpretation model is to naively accept the raw log reading. If the reservoir is shaly, or if the fluid density is not the same as water, a hydrogen-index linear-mixing law will generally do.
