Property Sensitivity Study For Oil Recovery In The Bakken, Daniel Beach

Graduate Theses & Non-Theses

The upstream (exploration and production) end of the petroleum industry has experienced tremendous success over the past fifteen years by employing innovative ways to drill and stimulate new wells thereby greatly increasing production. Based upon these successes, there has been a shift to unconventional wells, where the cost for drilling and completing wells can be much more expensive. Most unconventional wells target tight rock formations having low permeability and porosity. As a result, these reservoirs require enhanced stimulation to improve recovery operations to establish profitable oil or gas production. These wells are drilled horizontally to maximize contact area in the …

Balancing The Navigational Safety, Efficiency & Financial Aspects Of Oreis, Raza Ali Mehdi

MARENER 2017

The increasing number and sizes of offshore renewable energy installations (OREIs), combined with the ambitious plans for future developments in the sector, portray a bleak outlook for ‘traditional’ maritime and marine players: if the current plans for OREIs are realized, sea-space will become increasingly restricted for activities such as shipping.

Sustained growth of both OREIs and shipping may thus lead to situations where certain risk control options (RCOs) need to be adapted in order to maintain safety – despite the fact that such measures themselves may be counter-productive in terms of energy efficiency or financial sustainability.
