High pressure zonal isolation 534WAB
SUCCESSFUL ISOLATION: HIGH PRESSURE OPEN HOLE ZONESealing capability of the WAB vs swellable packer
34% INCREMENTAL HYDROCARBON PRODUCTIONProvides client with a higher NPV
ENHANCED WELL CONSTRUCTION REDUCES RISKWelltec’s solution provided proper zonal isolation
STRONG OPERATIONAL JOB PLANNING AND EXECUTIONEnsure WAB placement scenarios were catered for
Bottom WAB was RIH successfully to depth below “Los Cuervos” zone (Pauto Main) @ 18378.87ft. Top WAB was RIH successfully to depth above “Los Cuervos” zone (Pauto Main) @ 18138.59ft. Both WABs were expanded successfully with 5000 psi applied from surface against seated ball.
Welltec designed an effective compensation and equalization valve system of both high pressure from “Los Cuervos” shale of “Pauto Main” and the high pressure stimulation pressure inside the liner.
WAB allowed the “Mirador” Sandstones in the “Pauto Main” and “Pauto Splay” formations to be perforated and effectively isolated and stimulated. Due to the OH completion and more contact area, the client saw an increase in their estimated production from previous wells where cement was used.
WAB high pressure effective open hole zone isolation gains incremental production by 34% from originally expected.
Through its versatility in application and robustness in design, the WAB® (Welltec® Annular Barrier) for well completions can be utilized to provide solutions, to many requirements throughout the completion phase of a well.
