Dissolvable tools, plug-less and wave fracturing among innovations delivering more efficient multistage completions

The Infinity dissolvable plug-and-perf system uses degradable fracturing balls and seats instead of plugs to isolate zones during stimulation. The ball and seat disintegrate into a fine powder, eliminating the need for milling and enabling full-bore production. The system is suitable for multistage stimulation in various well geometries, including extended-reach wells and underpressured reservoirs.

The past 12 months have been marked by market volatility, pressures to cut costs and a drastic reduction in the number of onshore wells drilled. In the unconventional sector, however, innovation for multistage completion technology has not diminished. R&D efforts are pressing on in response to operator demands to drive down costs and boost recovery.

Analysis finds infrastructure is required to realize potential, drive exploration in East Africa

Market stocks default

With recoverable oil reserve estimates of approximately 750 and 600 million bbl in Uganda and Kenya respectively, and with government share of the reserves expected to be about 30–50%, the potential impact on economic development in these countries could be great. However, new infrastructure, including an export pipeline, is required to enable commercialization of these discoveries, says an analyst with research and consulting firm GlobalData.
