The role of well testing in geothermal resource assessment
… different approaches and methods for analysing well test data to estimate the capacity of a geothermal field are evaluated. The thesis lays emphasis on well completion and flow tests data, and uses the Reykjanes geothermal field in southwest Iceland as an example for the application of the …

A Mathematical Model of Horizontal Wells Productivity and Well Testing Analysis
This thesis presents new productivity and well testing formulae of horizontal wells. Taking a horizontal well as a uniform line source, this thesis finds velocity potential formula and the productivity formulae for a horizontal well in an ellipsoid of revolution drainage volume by solving …

Mitigating the impacts of arsenic on human health and rice yield in Bangladesh
… dose based on participants' primary household wells. Using a mass-balance for arsenic and water, we estimate that participants in Araihazar, Bangladesh obtain 37±8% of their water from primary household wells and 31±14% from other wells, and we thus recommend the inclusion of other wells in …

Modelling the La Soufrière hydrothermal system, St. Vincent and the Grenadines
… the models were based, consisting of GIS files, well data, drilling reports, various maps and cross-sections, internal reports, and scientific papers. This data was analysed and where necessary, interpreted in order to build a conceptual model of the geothermal system on the island. This model …

Modeling of Real Gas Flow Behavior in Porous Media
… the literature. Analytical solutions used in gas well testing and pressure analysis are based on idealized assumptions, such as small and/or constant gas compressibility and constant hydraulic diffusivity. These solutions, though widely used and easily applied, are not accurate. This research …

Establishing Ratiometric Characterisation in Bacillus Subtilis for Biosensing Applications
… in these countries is sourced from shallow tube wells installed to reduce the spread of diseases associated with poor water hygiene. In this goal they were successful, however by the mid 1990s it became apparent that many of these wells were contaminated by arsenic and that these countries’ rural …

Oil Potential of Middle Cretaceous Tight Carbonate in Mexico
… The Cretaceous carbonate was penetrated by well A1 and tested oil successfully during an open-hole test covering interval 5356 to 5515 m (MD) that produced oil of 33 degrees API. Initial pressure was 1050 kg/cm2 at 5,227 m (14,934.51 psi at 17,144 ft) that diminished gradually to 450 kg/cm2 …

Gravity studies of the Guayabo Caldera and the Miravalles geothermal field, Costa Rica
… for the gravity decreases observed during well testing in 1988, that could not be explained by reasonable mass changes. Talring these points into consideration, a repeat gravity monitoring program was designed to both test and complement the future reservoir simulation models.

Stochastic modelling for the analysis of blowout risk in exploration drilling.
… of probabilities related to kick, loss of well control, and blowout volumes; model input related to company and well specific parameters; and pro-active decision making in the development of drilling programmes to enable the identification and selection of risk-reducing measures as well as …
