The German Continental Deep Drilling Program (KTB) was designed to study the properties
and processes of the deeper continental crust by means of superdeep borehole. Major …

A fluid injection‐induced seismicity experiment was conducted in the German Continental
Deep Drilling Program (KTB) main borehole at 9.1 km depth (in situ temperature of 260° C) …

Estimating permeability from grain-size distributions or from well logs is attractive but difficult.
In this paper we present a new, generally applicable, and relatively inexpensive approach …

With the expansion of machine learning algorithms, automatic lithology classification that
uses well logging data is becoming significant in formation evaluation and reservoir …

Correct selection and interpretation of proxies are key to cyclostratigraphic research;
however, the uncritical use of geophysical logs as proxies for cyclostratigraphy could be …

A novel approach based on the concept of super self-adapting back propagation (SSABP)
neural network has been developed for classifying lithofacies boundaries from well log data …

Summary The 9.1 km deep KTB (Kontinentale Tiefbohrung, Germany) drilling hole is one of
the best investigated deep-drilling sites in the world. Among other parameters, in situ …

Abstract A 60-day, long-term fluid-injection experiment was performed at the 9.1-km-deep
Kontinentale Tiefbohrung, Germany (KTB), borehole. About 4000 m3 of water were injected …

Petrophysical properties of drill core and drill cuttings samples from both bore holes of the
German Continental Deep Drilling Program (KTB) measured at atmospheric pressure and …

Vertical seismic profiling (VSP) helps to derive high-resolution images around the
instrumented borehole and is a cost-effective technique for CO 2 storage monitoring. In …
