Calgary, AB (April 17, 2015) –On March 20, STEP Energy Services (STEP) successfully performed its first e-coil job for a Calgary-based independent exploration and production company in the Drayton Valley area.
The company was having problems during a fracturing stimulation on a new horizontal well completion; pump pressures between stages were irregular and the initial thought was that a poor cement job was to blame for horizontal isolation. A sand cleanout was performed using STEP’s custom 2” e-coil string using a wash nozzle at circulation rates of 400lpm, reaching a total measured depth of 5,700m. The cement bond log (CBL) was then performed to plug back depth showing poor cement isolation throughout the lateral and potentially damaged casing towards the heel. Based on these results, the call was made to perform a second logging run with casing callipers and a downhole camera. Once at the depth in question, multiple passes where made while streaming real time results to surface. It was concluded that the casing had sheared and collapsed. By using STEP’s e-coil, and the real-time data collected from the downhole tool assembly, the client was able to make quick and confident decisions saving money and time on frac standby and future operations.
“STEP’s latest integrated coiled tubing solution, e-coil, will help our clients better understand their wells,” says Marc Johnson, vice president of sales and marketing at STEP. “The data they will have access to will be invaluable when it comes to making efficient operational decisions based on real-time events in the wellbore.”
