and avoided faults and natural fractures
An operator working in the Eagle Ford formation of Texas was planning to drill a new well. In preparing to drill, however, challenges began to emerge. A series of complicated and unpredictable faults and natural fractures were dispersed throughout the area, many leading back to a large nearby aquifer. It was essential that the planned well avoid these hazards as five offset wells that had inadvertently tapped into this aquifer were producing only water. If the operator connected with the aquifer, it risked a total loss for the well and its USD 2.5 million investment. However, if the natural fractures could be incorporated into the completion design, enhanced completion efficiency and effectiveness could be realized. Baker Hughes designed a fit-for-purpose FracFit™ fracturing optimization solution to characterize the lateral, avoid potential water-producing zones, and improve the frac design. FracFit solutions are tailored to the specifics of each formation, designing and
executing an efficient, effective, customized stimulation program. Once the well’s horizontal section was drilled and cased, the XMAC™ F1 acoustic logging service was deployed on wireline as part of the FracFit solution. This service was paired with the deep shear wave imaging (DSWI) processing service to identify geohazards within 100 ft (30 m) of the wellbore and characterize the reservoir’s near-wellbore mechanical properties. The distribution of acoustic reflections and other wave-field attributes were used to build a deep shear wave image. Multiple through-going faults were revealed along the lateral that were potential communication pathways with the underlying aquifer. After identifying these downhole hazards, a multi-stage completion was designed as part of the FracFit solution, the natural fractures were incorporated into the design to obtain equal fracturing initiation for optimal efficiency and effectiveness and

fracturing optimization solution –– XMAC F1 acoustic logging service –– DSWI processing service –– Cuttings analysis
CASE HISTORY maximum reservoir exposure while avoiding all hazards. During the design phase, stage length and perforation placement were tailored by Baker Hughes using the XMAC F1 service’s acoustic information along with cuttings analysis. This combination of measurements helped the operator further reduce the risk
of fracturing within the faulted intervals and connecting to the water zone below the well. In a collaborative effort with the operator, the location of faults identified by the DSWI service was confirmed with realtime microseismic monitoring. The operator used this information to make on-the-fly adjustments that would prevent fractures from growing into potential water-producing zones.
The FracFit solution enabled the operator to secure a productive well near a large aquifer. The solution successfully characterized the wellbore and identified faults and natural fractures to be avoided during stimulation, mitigating water inflow to the well. The solution was executed without any NPT or HSE incidents and the operator realized USD 2.5 million in CAPEX savings.
