Maximum canyon depth is nearly 1,000 m; sediment fill consists mostly of dark-gray shale of the Gevaram Formation. Several sandy beds are present in the central part...

..., resulting in 1 oil discovery and 1 gas discovery. Oil production from the Helez-Brur, Kokhav, and Ashdod fields declined 30.4% during 1979 to 1981. Gas production from the Zohar field area was shut-in during most of the period. 1 Manuscript received and accepted, August 9, 1982. 2 Ministry...

... completed. Oil production from Helez field dropped by 43% compared to 1983, but production from the adjoining Kokhav field increased by 4%, mainly due to new production at the step-out well, Kokhav 26. Initial production was 54 b/d of 29° oil from an upper sand of the Helez Formation. Jurassic...

...Haya Shenhav ABSTRACT Sandstones from the Helez Formation (Lower Cretaceous) are the main oil reservoir rocks of the Helez-Kokhav field in the southern coastal plain of Israel. These sandstones make up about 10 percent of the Helez which is 200 m thick; their reservoir characteristics relate...

...Amos Bein; ZVI Soffer ABSTRACT In this case study of oils in the Helez-Brur-Kokhav oil field and nearby shows, organic geochemical criteria were integrated with geologic data to identify the source rocks and migration paths of the oils. The data presented, which include terpenoid biomarkers...

.... Two wells in the shallow Gonen gas field were unsuccessful. In Kokhav and Helez fields, 2 development wells were subcommercial and were not completed for production. Oil production in 1986 increased 29% from 1985 to a total of 85,653 bbl. This was due to recompletion of a well in Kokhav field...

Lapidoth, operator of the Helez-Brur and Kokhav oil fields, initiated new seismic surveys over the oil fields, using improved field methods. These surveys have clarified considerably the deep structure and are likely...
