Haynesville

Increase ROI from maximum reservoir contact

Our integrated development plans are setting a new standard of performance excellence in this HP/HT shale-gas play. With recorded temperature up to 315 deg and two times the typical pressure gradient, our multidisciplinary approach will help you achieve your drilling objectives. 

Combining geomechanical analyses and advanced mineralogic characterization, we’re designing better completion strategies and reducing drilling cost. Without this integrated approach, a hydraulic frac-treatment performance analysis would be difficult.

Optimized fracing from microseismic monitoring/analysis

We monitor and record in real time the microseismic events that occur during fracing. This gives us an accurate estimate of the fracture volume and direction, crucial to project optimization.

Our integrated development plan includes microseismic frac mapping for

  • hazard avoidance: karsts, faults
  • coverage of the lateral
  • understanding of stimulated volume
  • well placement for optimized drainage.

Operator saves $180,000 in high-temperature well

A Haynesville shale operator asked us to plan a horizontal well with fewer drilling days compared with the offsets. Measured average bottomhole operating temperature of 296 deg F. [147 deg C.] in this play can cause LWD and MWD tool-performance difficulties. Minimizing drilling time is vital.

We identified the zone of interest using high-quality gamma ray measurements, as part of our 6 3/4-in. and 4 3/4-in. M1XL™ motors with NaviTrak™ MWD system. The operator drilled 3,082 ft [939 m] at net ROP of 15 ft/hr [4 m/hr]. Excluding survey time, ROP was 25 ft/hr [8 m/hr].

The horizontal section was landed optimally and drilled lateral to TD in just 2 BHA runs. The operator saved 4 drilling days compared with the average offsets. Drilling cost was reduced 180,000 in this high-temperature, oil-base mud shale play. There were zero HS&E incidents.
