Focused Production Measurement System

Production logs have been an industry standard for many years, but by themselves they are not a reliable way to evaluate the complicated flow regimes in modern multistage wells. Production logs work well at determining the phases of flow in horizontal or vertical wells, but determining from which stage or cluster the production is originating is more of a challenge.

Refrac Roadmap™ Services

Refrac Roadmap™ services include measuring three-phase flow, temperature, static bottomhole pressure, and flowing bottomhole pressure to determine a well's in-flow performance.

Refrac Roadmap™ services increase and measure a flowing well's production, produce and measure a dead well's production, and can produce a zone or stage's absolute openhole potential.

Tech-Flo provides the full BHA, surface pump, and operations as a complete service.

Conveyance methods include jointed pipe, coiled tubing, or fiber coiled tubing. Suggested uses of this service include post-fracturing evaluation, prerefracturing evaluation, and evaluation of vertical wells with stacked pay.

After the test, a final report is provided detailing pressure, temperature and production data from each zone targeted.
