The rapid development of shale formations over the past decade has led the United States to become the world’s undisputed leader in natural gas production.

For openhole horizontal wells, providing power and data through an umbilical is very challenging.

The paper describes the hardware and user interface, the procedures for installation and acquisition, and several examples of field data and well-performance analysis for a variety of rod-pumping installations.

With more than a decade of experience acquired using Venturi/gamma ray multiphase flowmeters (MPFMs), further gains in measurement quality and operational robustness have been achieved.

This paper aims to develop criteria for identifying situations in which induced fracture complexity and sustained conductivity are or are not required.

This study provides a model for the inclined fracture case. It applies and further extends the unified-fracture-design approach for rectangular drainage areas, relating the dimensionless proppant number to the maximum productivity index in pseudosteady-state conditions.

Well plugging and abandoning on a limited budget is a lofty goal that forces the industry to consider new ways and new materials. Cost-effectively dealing with this global problem will require developing tools to carry out the decommissioning without bringing in a drilling rig.

Hybrid steam/solvent processes have gained importance as a thermal-recovery process for heavy oils in recent years.

An appraisal program involving the Bentley field located on the UK continental shelf has addressed the key technical concerns associated with developing viscous crude in an offshore environment.

An even temperature conformance along the length of the horizontal well is key in maximizing steam-assisted-gravity-drainage (SAGD) production rates.
