Given n potential oil locations, where each has oil at a certain depth, we seek good trade-offs between the number of oil sources found and the total amount of drilling performed. The cost of exploring a location is proportional to the depth to which it is drilled. The algorithm has no clue about the depths of the oil sources at the different locations or even if there are any. Abstraction of t...
The article deals with the selection of fluid solutions used in drilling oil and gas wells. As it is known, increase depth, liquid expands its density decreases. When determining hydrostatic pressure a fluid, recommended to take into account change temperature depending on depth well. To do this, important accurately determine law quality well depends basic physical properties. Thus, reservoir ...
fluid invasion from water-based drilling mud (wbdm) into the shale formations causes swelling,high pressure zone near the wellbore wall, and eventually wellbore instability problems duringdrilling operations. for the stability of the wellbore, physical plugging of nanoscale pore throats couldbe considered as a logical approach toward avoiding the fluid invasion into the shale formation. thispap...
Operational discharges of hydrocarbons from maritime activities can have major cumulative impacts on marine ecosystems. Small quantities of oil (i.e., 10 ml) results in often lethally reduced thermoregulation in seabirds. Thin sheens of oil and drilling fluids form around offshore petroleum production structures from currently permissible operational discharges of hydrocarbons. Methodology was ...
A puzzle that faces public administrators within regulatory governance networks is how to balance the need for democratic accountability while increasingly facing demands from elected officials to optimize oversight of industry by utilizing the expertise of the private sector in developing risk-based standards for compliance. The shift from traditional command and control oversight to process o...
The data measured by well bottom sensors can be transmitted to the surface through the drilling mud during oil drilling operations. This article introduces a data processing scheme for a wireless data transmission application via mud. The detailed signal processing procedure is given, and several data processing techniques used are discussed, mainly including data encoding and signal integratin...
The time for easy oil discovery and production for National Iranian Oil Company (NIOC) is over. This means that the oil is no longer discovered in structurally simple, i.e., almost flat environments like south of Khuzestan province (south west of Iran). This comes along with the fact that Iran’s biggest oil reservoirs are in this area, and they are passing half of their life cycle. These giant ...
This article examines learning-by-doing that is specific not just to individual firms but to pairs of firms working together in a contracting relationship. Using data from the oil and gas industry, I find that the productivity of an oil production company and its drilling contractor increases with their joint experience. This learning is relationship-specific: drilling rigs cannot fully appropr...
The oil well drilling process is the selected representative of a challenging industrial process. The drilling process is becoming more complex as oil fields mature and technology evolves. At the same time, the amount of information is increasing in volume and frequency. Although technology is advancing, failures occur at almost the same rate as before, leading to loss of valuable time. Wheneve...
