This research analyzed why the use of existing MFHWs for waterflooding has failed. Then, we investigated more favorable MFHW patterns designed from the beginning for secondary oil recovery. Analytical modeling was used to evaluate wells specifically designed to benefit from plane-to-plane waterflooding. Based on that, we have proposed a new well pattern design strategy for implementing waterflood in the tight oil formations.<o:p></o:p></span></pre><p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p><p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p><p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal"><o:p> </o:p></p></div></div></div></span></body></html>
