Four sites (953−956) were drilled north and south of Gran Canaria during Leg 157. The penetrated pelagic and volcaniclastic sediments can be identified by their different chemical compositions. This paper focuses on the volcaniclastic deposits that were logged in Holes 953C, 955A, and 956B. The sediments in these holes are mainly composed of hemipelagic, fine-grained nannofossil oozes with inte...

Although shale gas plays have been in the spotlight recently, natural gas in tight sandstones is actually also an important hydrocarbon resource. In many cases, tight gas sandstone resources can be developed more easily than shale gas reservoirs as the rocks generally have higher quartz content, and are more brittle and easier to complete for production. This chapter first gives an overview of ...

An integrated study using 3D seismic, wireline logs, and core analyses was conducted to establish strategies for exploring in compartmentalized, lowstand, prograding, deltaic systems. Frio sediments, averaging ~11,000 ft, are commercial gas reservoirs in several of the growth-faulted, intraslope subbasins in South Texas. These exploitation targets are typically located in faultbounded compartme...

Recent advances in wire-like communication channels without a physical wire has seen the emergence of wireline-like broadband but with atypical high loss. Communication links using such (e.g., Proximity Communication, Human Body Communication) are typically broadband, like wireline systems noise-limited wireless systems. Hence, employing broad-band through emerging calls for new research on ana...

We demonstrate the successful transmission of Data Over Cable Service Interface Specification (DOCSIS) signals in the 600 MHz and 5.5 GHz frequency bands. Both signals are generated simultaneously using an optical harmonic up-conversion of the DOCSIS signal provided by a cable modem termination system (CMTS). The optical signal is transmitted over 10 km SSMF. After photo-detection, the wireline...

A dynamic pre-allocated connection (DPC) scheme is proposed to support fast handoff and to effectively utilize wireline links. Since the proposed scheme uses pre-allocated switched virtual connections (PSVCs), handoff can be quickly executed in real-time with reduced connection overhead. This dynamic resource management scheme increases utilization of wireline links due to statistical multiplex...

Abstract In this study, we have assessed the petrographical and petrophysical characteristics of progradational, syn-rift Middle Miocene Rahmi sandstone gas reservoir (Lower Kareem Formation) from East Matr Amal hydrocarbon fields, southern Gulf Suez by integrating sidewall cores wireline logs. We interpreted a gradient around 0.09 psi/ft downhole pressure measurements. Based on well log-based ...

This paper presents an innovative solution for estimating the proximate parameters of coal beds from the well-logs. To implement the solution, the C# programming language was used. The data from four exploratory boreholes was used in a case study to express the method and determine its accuracy. Then two boreholes were selected as the reference, namely the boreholes with available well-logging ...

The estimation of the formation permeability is considered a vital process in assessing reservoir deliverability. prediction such rock property with use minimum number inputs mandatory. In general, porosity and are independent petrophysical properties. Despite these observations, theoretical relationships have been proposed, as that by Kozeny–Carmen theory. This theory, however, treats highly c...
