The PDG analyzes was performed in PolyGon pressure modelling facility and followed Multi-well Retrospective Testing (MRT...

... production history. For each group of fracture design and well spacing, well interference was determined by estimating ultimate recovery (EUR) difference between a single well and a middle well among multiple wells. Based on actual information of tight oil developments, the pressure interference were...

... while avoiding adverse effects due to well interference. Significant progress has been made in well design improvements based on physical models for flow in hydraulically fractured rock volumes. Such models attempt to integrate all the available geomechanical information, focusing on the engineering...

... Abstract Economic development of unconventional reservoirs heavily relies on hydraulic fracturing of horizontal wells in multi-well pads. The application of this technology poses the challenge of determining optimum well spacing. For this reason, well interference analyses have recently gained...

... of drainage area and fracture interference. Many operators use a method known as parent well protection (PWP) to help mitigate this effect and increase recovery from both parent (delineation) and closely offsetting development (child) wells. This paper presents an analysis of the economic impact of PWP...

... the wells in this study were completed with common stimulation programs for the area. Despite the typical estimated frac length, three of the subject wells experienced offset stimulation interference from offsetting wells or pads. These "frac hits" contributed negatively on the producing wells for a period...

As its name suggests, single well convolution is only applicable when there is no interference from other wells. i.e...

.... 1997 ). Abstract Reservoir stimulation by means of hydraulic fracturing has enhanced the production of hydrocarbons from shale. The latest methods concentrate on reducing the detrimental interference between fractures within the same well. The theory behind this is well understood, however...

... An algorithm was presented by Cumming et al, (2013) which extended a single-well deconvolution algorithm to encompass multiple wells within a reservoir, whilst successfully managing interference effects between the wells. This algorithm is still in its early stages of development, and has been...

It becomes dominant in high-permeability reservoirs, as well as in some intermediate- permeability or low-permeability reservoirs with short inter-well distance. Such effect makes the measured pressure...
