horizontal wells

This paper discusses novel acoustic techniques used to identify productive zones and areas of sand production in a well with a sanding event.

An automated detection application helped identify stringers early for an operator of a mature field in the North Sea while drilling multilateral wells through reservoir sections containing hard calcite stringers interspersed in sand formations with low unconfined compressive strength. The application guided drilling decisions that minimized invisible lost time and sh…

This paper presents a work flow that has been applied to crossdipole sonic data acquired in a vertical pilot well drilled in the Permian Basin.

The paper provides insights on diffusion in organic matter to correct a primary source of underestimation of gas production in shale-gas models.

This paper presents a mathematical analysis of how incorrect estimates of initial reservoir pressure may affect rate-transient analysis in ultralow-permeability reservoirs.

This paper presents a screenout-classification system based on Gaussian hidden Markov models that predicts screenouts and provides early warning.

This paper summarizes the integrated technical learnings from the successful application of the installation of autonomous outflow control technology in a new long horizontal injector well.

This paper presents an oil well completion integrating multilaterals, intelligent completions, permanent downhole monitoring systems, electric submersible pump (ESP) and a horizontal wellhead system.

The trend toward drilling longer horizontal wells is growing with lateral lengths of 3 miles reached.

The paper presents a system for separation of water in downhole horizontal wells in which the water produced from the well is not lifted to the surface but reinjected into the reservoir.
