West Cote Blanche Bay Overview

Prolific History.  Our West Cote Blanche Bay field is located in the shallow waters of St. Mary Parish, approximately 45 miles south of Lafayette, LA.  Since 1998, Gulfport has conducted its development activities in this flagship field on floating barge rigs, service vessels and our raised production facilities.  Highlighted facts regarding West Cote Blanche Bay include:

  • Located approximately five miles off the coast of Louisiana in a shallow water bay with water depths averaging eight to ten feet
  • Field's discovery well was drilled in 1940 based on a seismic and gravitational anomaly
  • 3-D seismic and directional drilling techniques drive the field's development today
  • Significant salt intrusive feature, eliptical in shape, created traps in the Pliocene through the middle Miocene in a series of complex, steeply dipping fault blocks
  • Intense faulting near and immediately above the salt stock leading to numerous compartmentalized reservoirs; less intense faulting further away leading to larger, more continuous reservoirs 

Growing Production and Valuable Reserves.  The West Cote Blanche Bay reservoirs are characterized by high porosity and permeability.  Each well path contains stacked pay zones and is designed to exploit an average of five to six pay zones per well bore.

  • Substantial cumulative gross production for the field is estimated to be approximately 227 MMBOE
  • At 12/31/07 Netherland Sewell had evaluated 111 booked PUDs
  • There are over 100 different formations that have produced within the field
  • Within the over 850 wellbores drilled to date, over 4,000 potential zones have been penetrated
  • Deep prospective gas opportunities at WCBB - 10 Bcf potential
