Abstract: A method of deploying a pump in a well production tubing using an electrical cable includes attaching a downhole barrier valve (DBV) to a spoolable conveyance. The DBV is closed to flow in both directions until a differential pressure across the DBV exceeds a first threshold. The DBV is closed to flow when the differential pressure falls below the first threshold. The DBV is moved to a selected depth in the well by extending the conveyance through a lubricator attached to a wellhead at an upper end of the production tubing. The spoolable conveyance is withdrawn from the well. The pump is attached to the electrical cable and is moved through the wellhead and the production tubing by extending the cable until the pump reaches a selected setting depth in the well.

The model is further updated over subsequent iterations of the diversion phase when the actual response is less than the estimated response. Subsequent diversion phases are performed over a remainder of the current stage, based on the updated model.

An initial information-gathering procedure is conducted, wherein fluid is supplied under a pressure less than formation dilation or fracture pressure, to discrete intervals along a first wellbore, and sensors in the second wellbore measure and data is recorded regarding the ease of penetration of such fluid into the various regions of the formation intermediate the two wellbores.

Abstract: A well with existing perforations is re-fractured by positioning isolators at locations offset from the existing perforations and perforating through those isolators. The isolators are part of a bottom hole assembly that can be delivered on coiled or rigid tubing. The initial fractures can be straddled by the isolators with no mandrel openings between them to effectively isolate the existing perforations as new perforations take place through the isolators. The elements of the isolators can have internal gaps to allow for axial shifting after perforation that is thermally induced. The gaps assure remaining alignment with the new perforations despite some axial shifting. The bottom hole assembly can alternatively have an anchor to resist thermally induced forces that can cause axial shifting.

Abstract: Fractures are induced from lobe shaped inflatable members disposed at different axial locations along a string with frac ports in the circumferential gaps between the lobes. The lobes are inflated by landing a ball on a seat on a sleeve that is initially shifted enough to expose a fill port on each lobe. The lobes are inflated to a pressure that initiates fractures in the formation as the lobes extend. Further raising the pressure induces the sleeve to move a second time to open frac ports. The annulus can be cemented and fracturing can penetrate the cement to further propagate the initiated fractures from lobe inflation. The process is repeated at different levels until the zone of interest is completed. Sensors can relay information by telemetry techniques as to the onset of fractures or other well conditions. The sleeve for the frac ports can be moved in a variety of ways without intervention tools.
