Fracture morphology in Cretaceous carbonate reservoirs from south-east Turkey
Authors M. Özkanli and E.J.W. StandenThe aim of this article is to demonstrate the measurements of the degree of fracturing and the orientation of the natural fracture systems within reservoir units by using electrical (FMS) and acoustic (BHTV) images. Borehole imaging is an economical method of evaluating the distribution of reservoir porosity systems, especially fractures, in the sub-surface. Along with accurate orientation of the fracture events, a calculation can now be made of fracture aperture, density and porosity, both vertically and horizontally in the region of the wellbore. This is performed after calibration of the image data to a Laterolog Shallow or Spherically Focused resistivity measurement.

Lower Cretaceous seismic stratigraphy and fault movement in the Celtic Sea Basin, Ireland
Authors T. McCann and P. M. ShannonThe Celtic Sea region encompasses a series of basins and sub-basins lying off the south coast of Ireland, and extending into UK-designated areas (Fig. I). The major basins are the North and South Celtic Sea basins, which are separated by a long-standing basement high, the Fastnet Basin and the Cockburn Basin. A number of recent publications have outlined the regional geological development of the area (Naylor and Shannon 1982; Tucker and Arter 1987; van Hoorn 1987; Ziegier 1987; Shannon 1991a, b, c). The present study is confined to a small area located on the westernmost limb of the North Celtic Sea Basin, and north of the Fastnet Basin (Fig. I).

Some problems in velocity analysis for marine deep seismic profiles
Authors J.H. McBride, G.A. Lindsey, R.W. Hobbs, D.B. Snyder and I.J. TotterdellThe petroleum industry has identified deep seismic profiling as an additional means to assess frontier exploration areas. Those of us working within the British Institutions Reflection Profiling Syndicate (BIRPS) have recognized velocity analysis to be one of the most crucial steps in the data processing stream for deep seismie data. Although also true for conventional processing for sedimentary basins, the drastic differences in the depth, seismic velocity, and structural complexity of the target in the crust and upper mantIe force one to change the relative emphasis placed on the various aspects of velocity analysis.
