Directional/complex wells
This paper discusses the development of a multientry, multistage fracturing system and its advantages over traditional openhole multistage fracturing solutions.
This paper proposes a methodology for preventing drillstring fatigue and failure in deep wells with large shallow doglegs.
In this paper, the authors propose a regression machine-learning model to predict stick/slip severity index using sequences of surface measurements.

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.
-
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 presents the results of a performance-improvement effort in extended-reach drilling (ERD) in three campaigns in the Huizhou HZ 25-4 oil field in the South China Sea.
-
A common well-completion configuration for shale-gas wells is a horizontal well with multiple transverse hydraulic fractures.
-
Irrespective of industry or sector, the objectives of innovation are productivity and performance improvement and cost reduction.
-
A new workflow technology has been launched that uses real-time logging-while-drilling (LWD) data and a new horizontal well-correlation technique to dynamically update a structural framework that can be used to geosteer an active drilling well.
