|Lake Washington Field Recent Updates
The Lake Washington field is one of two fields in our Southeast Louisiana core area of operations. Located in the northwest corner of Plaquemines Parish, it is an inland-water field that produces oil and natural gas liquids from multiple stacked Miocene sand layers radiating outward and downward from the surface of a centrally located salt dome. Drilling and completion operations in the field, which is highly faulted, are conducted from barge-based rigs. We acquired our first properties in the field in 2001, purchasing additional reserves in 2006. Our early wells were drilled to depths of approximately 6,000 feet, but after 2004, when we conducted a three-dimensional seismic survey over the field and subsequently developed a proprietary geoscience database over 700 square miles, we began drilling to depths exceeding 16,000 feet. Lake Washington has undergone significant infrastructure development, both before and following extensive damage from Hurricane Katrina, including the addition of a new production processing facility in mid-2008.
Following the collapse of commodity prices in 2008 and our subsequent focus on horizontal drilling in South Texas, we have deferred drilling deeper wells in Lake Washington and instead have conducted a production optimization program that consists of drilling shallow to medium-depth wells, performing recompletions, implementing sliding sleeve changes, and carrying out numerous other operational activities to maintain the field's production level. During 2014, we did not drill any wells in the field, but in our production optimization program, we performed 23 production enhancement operations. Approximately 97% of our year-end 2014 proved reserves in the field consisted of oil and natural gas liquids. At year-end 2014, we had 26 proved undeveloped locations in this field.
March 2, 2014: FORM 10-K. Since its discovery in the 1930's, the Lake Washington field has produced over 300 million Boe from multiple stacked Miocene sand layers radiating outward from a central salt dome which are heavily faulted, thereby creating a large number of potential hydrocarbon traps. Approximately 97% of our proved reserves in this field consist of oil and natural gas liquids (NGLs) that are gathered to several platforms located in water depths from 2 to 12 feet. Drilling and workover operations are performed with rigs on
In 2014 we did not drill any wells in Lake Washington, but in our 2014 production optimization program we performed 23 recompletions and numerous production enhancement operations, including sliding sleeve changes, gas lift modifications and well stimulations. At December 31, 2014, we had 26 proved undeveloped locations in this field.
