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.

This study used structural contour maps to carry out the geometrical analysis for Faihaa structure in Basra southern Iraq. The study used row data of well logs and structural maps while Softwares were Didger 4, Stereonet v.11 and Petrel 2017 Faihaa Oil Field is located at an eastern part of the Mesopotamian Zone within the Zubair Subzone, characterized by subsurface geological structures covered by Quaternary sediments. These structures are oriented in the NW-SE direction in the eastern part of the band and the N-S direction in the southern region, and some in the direction NE-SW. The Faihaa Oil Field shows that is an Anticline structure. The average dip value of an axial surface is 89.7° while the plunge of hinge line between 4–4.2 in North-West direction referred to that Faihaa Structure is upright and gentle fold. Based on the Thickness ratio and axial angle, the Faihaa Structure is thickened Fold. The eastern limb of the fold is longer than the western limb, so Faihaa Oil Field is an asymmetrical structure. The difference in dimensions (5<Length / Width < 2) confirmed the brachy fold of the Faihaa structure.

The discovery of the Pollard oil field in southern Alabama early in 1952 sparked a campaign of leasing and exploration which spread quickly into Georgia and Florida. Three fields in southwestern Alabama and one in southern Florida account for all the oil production in the three states. Some aspects of the general geology and geophysics of the area, illustrated with maps, cross sections, and correlation charts, suggest the presence of geologic conditions favorable for the possible trapping and accumulation of oil and gas. Early seismograph exploration in much of the area was not effective, but in recent months the tempo of seismic activity has been accelerating, and improvements in instrumental and interpretive techniques are being achieved through current experimental work. The use of the various geophysical methods contributed to the discovery of the four oil fields located in the area. The structural traps indicated by the contour maps of the four fields are of the type sought by the reflection seismic method. Examples of representative reflection records indicate the presence of usable and correlatable seismic events. A seismic cross section prepared from data of this type shows the fault zone associated with the Pollard field. The existence of favorable geologic conditions in the southeastern states and the recent oil field successes at Pollard and South Carlton indicate the continuing of active development and exploration throughout the area.

Geologic, geochemical, and geophysical measurements were made at the Cement oil field, Oklahoma, test site using airborne and spaceborne sensors coupled with ground‐based data collection. The data collected include (1) airborne gamma‐ray spectrometry ([Formula: see text], [Formula: see text], [Formula: see text], and total intensity channels), (2) low‐altitude aeromagnetic profiles, (3) precision gravity measurements, (4) images from the Landsat multispectral scanner (MSS) systems and U-2 photography, and (5) geologic and topographic maps. In order to reduce, analyze, display, and correlate the information, it was necessary to transform the data from vector space to raster space (a two‐dimensional image array) with fixed resolution and array dimension. With the data in array form, spatial array processing techniques were applied to (1) correct geometrically the data for proper registration, (2) perform areal interpolation and smoothing, (3) display the data as images, and (4) perform integration and correlation studies. Each data set was transformed into a rectangular array covering approximately 0.3 degrees of latitude and longitude, with each picture element encompassing [Formula: see text]. Because most variables only sparsely populate the raw image array (i.e., flight line data), the data were interpolated and smoothed using spatial filtering techniques to construct continuous images. The individual data sets were displayed as black and white continuous tone images, color coded to form color contour maps, or manipulated to generate shaded‐relief models. Methods for correlation and data interpretation were systematically investigated by using all available sources. Predetermined factual information (“prior knowledge” correlation statistics) was used to establish grounds for correlation and better define the limits of the data. This kind of data manipulation provided an enhanced pictorial representation of the geologic, geochemical, and geophysical anomalies previously documented at Cement.

Nahr Umr oil field is one of the important productive southern Iraqi oil fields. This studyfocuses on the type of fold and faults of the Nahr Umr oil field. A structural analysis(geometric and genetic analyses) performed to identify its type, origin and to find its relevanceto main regional tectonic events. The structural classifications employed well and geophysicaldata through using structure contour maps, cross sections, and seismic section.The structural analysis inferred that fold of Nahr Umr oil field classified as antiform, upright,non-plunge, gentle, supratenous, dome feature, and asymmetrical. The limbs are unequalwhereas the length of left limb shorter than the right limb and its dip is greater than right limb.In addition, the thickness of crest is less than the thickness of limbs. Pattern of faults classifiedas compound, parallel, conjugates and radial with graben structure and these faultsconcentrated on crest of fold. The fold axis is almost N-S at early cretaceous and then clearlyturns to NW-SE and this may due to counterclockwise rotation of Arabian plate. Geophysicalinterpretations and results of structural analysis stated that Nahr Umr oil field formed by threecombined forces which are tectonic movements, reactivated basement, and salt structures.

AbstractIn this paper we present complete two-dimensional measurements of the observed brightness of the 9th November 1990Hαflare, using a PDS microdensitometer scanner and image processing software MIDAS. The resulting isophotal contour maps, were used to describe morphological-cum-temporal behaviour of the flare and also the kernels of the flare. Correlation of theHαflare with SXR and MW radiations were also studied.
