Directional/complex wells
This paper presents an efficient mathematical optimization method for well placement that maximizes contact with the productive zones for the best locations in the reservoir.
Bad vibes are being addressed by contractors as operators push to go faster, deeper, and longer with unconventional wells.
The service giant shares how its new technology can sense rock properties 50 ft ahead of the bit in horizontal wells.

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 development of multilateral wells and long-reach wells has become important to maximizing recovery for many oil 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 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.
-
The oil industry has always been innovative, even under adverse and challenging conditions imposed by the nature of upstream projects.
-
This paper presents a case history of a North Sea well in which managed-pressure drilling (MPD) was used as the enabling technology to drill, case, and cement the well.
-
This paper describes placement of horizontal wells in this kind of heterogeneous reservoir through an integrated approach.
