This paper presents an investigation of the fracture properties and their effect on pressure and pressure derivative signature in multilateral wells at dry gas reservoir as well as the effect of the number of laterals, length of laterals and reservoir anisotropy. The base case scenario...

... The geological, geomechanical, geochemical and petrophysical characteristics in shale vary considerably both vertically and laterally across short distances. Often, minimal emphasis is placed on reducing subsurface uncertainty. What is not always appreciated is that the variability of mineralogy...

... The PML (Producer Multilateral) wells are planned with TAM Level 2 to have 6-1/8" open hole multilaterals reservoir sections which are drilled from cased hole. The number of laterals varies from two to five, being four the most common in this field under study (motherbore plus three laterals...

The in-situ stress regime in this field is predominantly strike-slip faulting and the drilling azimuth represents a dominant stability component. The current study analyzes 58 laterals sidetracked...

...Well Construction and Completion Design An existing single lateral well with 7 in. casing and 4½ in. liner was converted to multilateral well to test the electric-hydraulic intelligent completion. Figure 5 below shows the initial well condition and the proposed multilateral. The workover...

Yet, it is very important to highlight that the benefits of implementing smart completions are only as good as the optimization plan in selecting the right choke sizes on each lateral...

... Four downhole hydraulic ICVs obviously qualify this well as a smart well. These valves provide necessary controls to choke/shut-in laterals and they have 11 positions, including fully open and fully closed.

... and reduced reservoir contact. Factors affecting this are formation, well profile, tortuosity, etc. These issues can be mitigated by using a rib-steered motor (RSM), with which it is possible to increase lateral reach by drilling smoother wellbores.
