Early geophysical exploration in the Anahuac area from 1925 to 1929 included refraction fan shooting and a torsion balance survey. A reflection dip survey in 1933 indicated a large structural closure on which the discovery well was drilled in 1935. No detailed geophysical work has been done on the structure since the discovery of the field.

In order to demonstrate the growth of our knowledge of a typical Gulf Coast salt dome concurrently with development of the science of geophysics, the successive application of various techniques to the exploration of the Cameron Meadows dome is described and illustrated. These methods were: mechanical refraction seismograph (1926); torsion balance (1927); electrical refraction seismograph (1928–29); early correlation reflection seismograph (1929); dip reflection seismograph (1933); special salt profiling refraction seismograph (1942); continuous correlation reflection seismograph (1942); gravity meter (1943.)

The geophysical activity which led to the discovery of the Lovell Lake oil field was begun in 1929 when it was delineated as a minimum by the torsion balance. Two reflection seismograph surveys preceded the drilling of the discovery well, and a further detailed reflection seismograph survey after the discovery was made to outline the dimensions of the structure more definitively.

This paper presents a historical record of the geophysical activity in the area of the La Gloria Field. The successive stages of geophysical exploration were: Torsion balance survey 1934–1935; correlation reflection seismograph survey 1936; dip reflection seismograph survey, 1938; correlation reflection seismograph survey, 1938; gravity meter survey, 1943–1944. The discovery well, Magnolia’s Sam Maun No. 1, was drilled and completed in 1938–1939, producing initially 165 barrels per day of 65° gravity distillate and 5,646,000 cubic feet of gas through a 5/16 inch choke. Oil and gas in the La Gloria Field are being produced from sands in the Frio formation of Oligocene age. There are a number of sands producing gas‐distillate. Several flank wells produce oil. The field has been unitized and a cycling plant is engaged in processing the gas‐distillate.

This paper presents a chronological historical record of the geophysical activity in the area near the town of Mamou, Louisiana which subsequently led to the discovery of the Mamou Oil Field. The successive stages of geophysical exploration were: 1. Mechanical seismograph refraction survey by North American Exploration Company (German company) in August 1926 for Magnolia‐Union Sulphur‐Harry Hanszen. 2. Torsion balance survey by Shell Oil Company in 1934. 3. Magnetometer survey by Atlantic Refining Company in 1936. 4. Torsion balance survey by Atlantic Refining Company in 1936. 5. Gravity meter survey by Magnolia Petroleum Company the latter part of 1942 and early part of 1943. 6. Three weeks’ seismic work by Petty Geophysical Engineering Company for Magnolia Petroleum Company in June 1943. 7. A few weeks’ work by General Geophysical Company for Cities Service Oil Company in June, 1943. 8. Detailed seismic survey by Independent Exploration Company for Magnolia Petroleum Company from November, 1943 to June, 1945. The discovery well, Magnolia’s No. 1 J. B. Morein, was completed December 28, 1945 through perforations from 11,520 feet to 11,530 feet, producing 208 barrels of 46.3 gravity oil and 770 MCF gas per day through 8/64 inch choke. There are three producing horizons in the upper part of the Wilcox group. The first, or Morein stringer, is approximately 5 feet thick and lies about 18 feet above the second, or Morein sand, which has 19 feet average production thickness. The third, or Deshotels sand, has an average productive thickness of 10 feet and is approximately 230 feet below the Morein sand. Twenty producers and five dry holes were drilled. The field has been unitized and is being water‐flooded. Total production of the field to January 1, 1954 was 2,498,373 barrels. December, 1953 production was 20,604 barrels.

Interest was first attracted to the Budafapuszta area by its geographical position on the eastward projection of a known surface anticline, which had produced small quantities of oil at Peklenicza and Szelnicza. A test was located in 1920 on a small surface feature, and completed in 1923 as a dry hole. In 1934 a torsion balance survey was made by Eurogasco, a subsidiary of the Standard Oil Co. (N. J.) which indicated a dome with its crest 1500 m. north of the dry hole. A reflection survey verified the presence of the structure. The discovery well was located by the torsion balance data, and completed as a producer in 1937. A gravity meter survey made after the first two producers had been drilled, gave further information on the structure and assisted in the development of the field. This exploration history shows that a properly made torsion balance survey may be very efficient and economical even in hilly country. A geological map of part of the Szelnicza‐Peklenicza anticline, a topographical map, torsion balance, seismograph and gravity meter maps, a seismograph cross section and a subsurface contour map of the Budafapuszta structure are submitted.

In 1951, the French Government granted an exclusive exploration permit to the Esso R.E.P. (a Standard Oil Company affiliate) over an area of 4,357,980 acres around Bordeaux in the northern part of the Aquitaine Basin, France. This area was investigated first by surface geology; then it was surveyed by the gravity meter. In checking the gravity anomalies by the reflection seismograph, a subsurface structure was found at Parentis in 1953, which was drilled in 1954, and was proved to be oil bearing. The Parentis oil field is the most important oil field, not only in France, but in all Europe outside the Iron Curtain. Gravity map, seismograph map, seismic profiles, telluric map and geological contour maps, and cross sections of the Parentis structure are presented.

An historical outline of the development of the gravity method of prospecting is presented. While the very early gravity work with pendulum equipment was for geodetic purposes alone, the increased instrumental sensitivity made available with the development of the torsion balance by Eoetvoes (1888), led in 1915, to the first gravimetric survey for oil prospecting in the Egbell field, Czechoslovakia. The application of the method to prospecting in the United States started in 1924 with the discovery of the Nash dome in Coastal Texas by a torsion balance survey. The development and use of improved pendulum equipment is discussed and finally the recent marked increase in gravity work resulting from the introduction of the gravimeter about 1930 to 1935.
