INTRODUCTION
Oil test wells can provide information on the depth, age, inclination, porosity,permeability, density, faulting, folding, and organic content of geologicformations mapped at the surface, or on units not recognized in surfaceoutcrops. Formation density, as expressed in sonic and density logs commonlyobtained when wells are drilled, has become increasingly important in making acrustal-scale 3-D seismic velocity model for the San Francisco Bay region. Thismodel will be used for the calculation of realistic strong-ground motion syntheticseismograms (Brocher and others, 1997), and to determine the geometry of thebasement surface beneath Tertiary basins (Jachens and others, 1997). Theavailability of this density and other information for oil test wells has, untilrecently, been restricted for competitive reasons, but several petroleumcompanies have recently made these data available. Accordingly, we began in1992 to obtain these data to help prepare new geologic maps and geophysicalmodels for the San Francisco Bay region, and to share the information with thepublic.
AREA COVERED
This report contains brief descriptions of information and materials availablefor 1,550 oil exploration and production wells in the following counties: Alameda(42), Butte (31), Colusa (103), Contra Costa (102), Glenn (103), Humboldt (33),Marin (6), Mendocino (2), Merced (33), Monterey (172), Napa (5), Placer (2),Sacramento (72), San Benito (51), San Joaquin (164), San Mateo (73), Santa Clara(8), Santa Cruz (23), Shasta (3), Siskiyou (1), Solano (251), Sonoma (10), Stanislaus(29), Sutter (59), Tehama (59), and Yolo (113).
TYPES OF DATA
We have been most interested in wells that have sonic and density logs,depths to the various geologic formations, information on lithology, the names,character, and diversity of microfossils, the original slides or vials withforaminifers or nannoplankton, and paleo logs that indicate the character of themicrofossils at various depths. Where available, we have also collected electricallogs (E logs) and mud logs, which show the drilling rate, visual porosity,lithology, oil and gas content, physical properties and chemistry of the drillingmud, and a description of the cuttings. In the database, density logs are includedin the space allocated for sonic logs.
The most useful paleo logs (shortened from paleontology logs) have anelectrical log on the left side, formation names and biostratigraphic stages, zones,and ages in the middle, and a description of fossils and unusual minerals in acolumn on the right. Many paleo logs also have information that was nottransferred to this summary, such as strike and dips of bedding and the characterof other fossils from the well.
Many slides with foraminifers (shortened to forams for brevity throughoutthis report) from cores and cuttings were received with no accompanying data.Presumably data for these wells are available from Jennings and Hart (1956), the
4
California Division of Oil and Gas, published reports in libraries, or fromcommercial oil-well data companies.
Nearly every slide has 3 circular compartments for forams. Most of thesecompartments have only loose forams, but a few picked and mounted material.Vials contain mainly loose forams, silt, and sand grains.
Many more wells are available than shown in this list. Wells drilled prior to1950 were generally omitted if the data are sparse. Conversely, some well filesare enormous, occupying several feet of shelf space in an oil company library,but we copied only the data of most interest to our projects.
ARRANGEMENT OF THE DATA IN THIS REPORT
Within each county, the data are arranged alphabetically by lease namefollowed by the name of the company responsible for the well. Because bothnames may have changed over time, we have provided former names whenknown. The exceptions are Chevron, formerly Standard; Arco, formerlyRichfield ; Exxon, formerly Humble; Texaco, formerly The Texas Co.; andUnocal, formerly Union.
The section, township and range are from the data provided, and werechecked only for wells of interest to our projects. The number provided at thebeginning of the geology notes section is a company reference number for thewell. The rest of the information in the geology notes was taken mainly fromdata obtained from the various oil companies.
PROBLEMS WITH THE DATA
Almost every entry in our report may have errors, even such things assection, township, range, county, quadrangle name, and drilling depth. Thedepths and ages given for formations are particularly subjective. Few of theseformations are defined in accordance with the North American Stratigraphiccode, and their position in a well may be defined by correlation with nearbywells, by paleontologic or mineral content, by geochemical or geophysicalcharacter, or by thermal maturation. Zone and stage assignments generallyfollow those of Laiming (1943), Goudkoff (1945), Kleinpell (1938) and Mallory(1959), but Poore (1980), Almgren (1986), Almgren and others (1988), and severalothers have pointed out major difficulties in using these stratigraphic standards.Moreover, some oil company micropaleontologists have not made rigorousdistinctions between paleontologic and lithologic terms. The use of the term“Capay”, for example, could mean a rock correlative with coarse clastic rocks inthe Capay’s type area but it is almost certainly a faunal term for a shale withEocene faunas correlative with the C zone of Laiming. If an electrical log isprovided, the lithology can be checked, but many paleo logs do not haveelectrical logs.
Many of the ages on the paleo logs are obsolete. The Paleocene was notrecognized in California until the late 1930’s, and the zone assignments have alsochanged. We have attempted to update this information, so that the data in ourreport do not correspond exactly with the original data. Similarly, we haveinferred lithologic information for some names when the lithology is notprovided in the data, such as shale for the Capay and sandstone for the Markley.
5
The Domengine, however, may mean a glauconitic sandstone, a whitesandstone, or a sandstone and shale sequence. An electrical log is very helpful inchecking names used by paleontologists.
The quality of the foram faunas (sparse, fairly good, and good) reflects acasual look at the list of forams on the well log. The quality is affected by thespacing of the washed samples, commonly 20 feet but as large as thousands offeet, or the samples may never have been washed. Quality will also be affectedby washing techniques, character of preservation, and how the samples wereobtained. Some companies for example, will only loan or give incomplete orpoorer parts of their collection to another company. Core samples generallyyield better preserved specimens than ditch samples.
Reworking of forams into younger formations and caving of forams intoolder formations is apparently common in many wells. Lab contamination is alsocommon. Hopefully, the paleontologist will make comments on the paleo logabout these occurrences.
The slides may be numbered consecutively, but the shallowest and deepestsamples may not be in order. Moreover, the numbers on the slide may beinterspersed with letters, so that the highest number may not be the totalnumber of slides. Some slides are marked with depths greater than the totaldepth given for the well.
The problem of correlating between written data and foram slides isespecially difficult because the foram slides provide the original names and thewritten data the newer names, and neither may have any of the same names.Several wells have the same lease name but different company names, and thedata may be insufficient to determine if the wells are the same or different.
For all of these reasons, our report should not be used as an authoritativesource, but only as a general guide to the kind of information available inselected company files.
ACKNOWLEDGEMENTSWe are most grateful to the paleontologists, geologists, and managers withChevron, Unocal, and Exxon, who provided most of the materials for this report,or allowed us access to their files. We are also grateful to personnel in Texaco,Arco and Shell for their contributions. Richard Stanley, U. S. Geological Survey,Richard Thorup and Alvin Almgren, consultants, and Joseph Clark, IndianaUniversity of Pennsylvania, kindly donated well logs and other materials for ourproject. Bette Hamachi organized the files several years ago, and LouiseDickerson made an early draft of information available from a published reportby Jennings and Hart (1956). U. S. Geological Survey volunteers John Parker,Larry Dickerson (deceased), William West, Karen Wild, Purty Dorn, SonokoMigitaka, Domenique Granier, and others helped in many ways.
