Directional/complex wells
This paper aims to establish a set of best practices for generating particle-size-distribution data from core samples.
A shared digital mindset across subsurface, subsea, and drilling and wells is accelerating well planning at Vår Energi.
This paper aims to assess the effectiveness of using advanced integrated production-data-analysis techniques for condensate-rich tight gas fields.
-
West Africa has seen a significant shift in drilling activity, mainly in deep water. Many of the major international operators are carrying out important exploration-and-development activities there. -
The development of multilateral wells and long-reach wells has become important to maximizing recovery for many oil fields.
-
The combination of ultrasonic pulse-echo and flexural-attenuation measurements was adopted in this project in the South China Sea for cement-integrity evaluation.
-
The first multilateral well in a North Kuwait field has been drilled recently.
-
Complex reservoirs in the Junín block of the Orinoco oil belt of eastern Venezuela offer challenges in achieving higher production rates and maximizing extraheavy-oil recovery.
-
The Burgan reservoir consists of vertically stacked channel sands along with a fault network connected to the aquifer and contains highly viscous reservoir fluid.
-
Tar mats are encountered in many Middle East carbonate reservoirs. In cases in which tar acts as a flow barrier between water and light oil, water injectors work most efficiently when placed horizontally immediately above the tar mat to maintain pressure support during production.
-
The ultimate performance of fractured wells in tight reservoirs is affected severely by the interfering effects inside the fracture and interfractures.
-
Horizontal- or complex-geometry-well construction projects are potentially good candidates to work out new contractual arrangements. Authorization to proceed with these projects is technically based, and measurable key variables can be defined.
-
This paper describes placement of horizontal wells in this kind of heterogeneous reservoir through an integrated approach.
