WTA Services

Well Test Analysis (WTA) & Engineering Services began engineering and consulting services in November 2005. The principal consultant has about thirteen years of proven successful and related experience and knowledge, which has been developed in the areas of ERCB well test compliance (related to the Well Test Capture system), well test analyses, determination of well performance and reservoir studies.  WTA Services is in association with Introspec Energy Group Inc. (I.E.G.), Petroleum Consultants.

We do the "homework" and determine if your well has potential for increased productivity. Direct your company's investments on wells that have potential and re-evaluate the effectiveness of these stimulated wells. Clients have testified where pressure transient tests were analyzed by WTA Services, in which some indicated potential for increased production through stimulation. These wells were stimulated as suggested by WTA Services and production increased 2 to 3 times, essentially close to pressure transient analysis (PTA) results. Another client has indicated increased production of about 8 times, again near PTA results.
 
Skin / Formation Damage:
 
< -4.0 indicates effective completion / stimulation or no formation damage.
 
-1.0 to -3.0 indicates some improvement / no formation damage.
 
-0.5 to +0.5 indicates undamaged / unimproved wellbore (indifferent)
 
+1.0 to +4.0 indicates some near-wellbore damage.
 
>+5.0 indicates a damaged wellbore.
 
>+10 indicates a seriously damaged wellbore.
 
Positive Skin results could indicate potential for stimulation and therefore, potential for increased productivity.  Direct your company's investments on wells that have potential.
 
Our consulting services include the following:

• Pressure transient analysis (PTA - Buildups, Falloffs, Drawdowns, DFITs/Minifrac/Afterclosure, DSTs) via conventional methods and simulation using Fekete Software
• Determine reservoir pressure, oil well productivity, gas well AOF and deliverability, fluid flow characteristics / reservoir permeability, completion effectiveness and boundaries / anomalies
• Single shot acoustic well sounder (AWS) calculations and reports
• Monitor pressure buildup tests via diagnostic plots for sufficient PTA
• Material balance and volumetric calculations (assess reservoir extent and limits before tie-in)
• Production forecasting 
• Critical rate calculations (minimum gas rates to lift liquids)
• Bounded/coiled PTA reports (formal)
• Manage electronic (PAS file) submissions and compliance issues of well tests (related to the Well Test Capture system) and annual pressure survey
• Assist in finalizing company standard reports
• Assist in preparing data for company standard analysis
