Creating multiple clusters per frac stage using the plug-and-perf method has been a common completion method for many years. However, this method can leave something to be desired when it comes to efficient treatment of each cluster, Amit Singh, Well Stimulation Specialist at Chevron, said in a presentation at the 2017 SPE Hydraulic Fracturing Technology Conference on 25 January in The Woodlands, Texas.

Halliburton recently announced that two of its RapidStart Initiator CT (casing test) sleeves opened after 32 months downhole. That time period represents an industry record for the successful operation of a toe sleeve, according to the company. Murphy E&P needed to perform a true casing integrity test and had deployed the RapidStart Initiator CT frac sleeve system as an interventionless means of establishing a flow path at the toe of the well. Both sleeves opened successfully after 32 months downhole in two drilled but uncompleted (DUC) wells of more than 7,000 ft, with static bottomhole temperatures up to 215˚F. The sleeves were functional at a total pressure of 10,000 psi and provided a 30-min casing...

New proppant transport technology targets high-salinity water applications

screen-shot-2017-01-30-at-3-45-01-pm

Fairmount Santrol recently launched Propel SSP 350. It is an extension to the self-suspending Propel SSP proppant transport technology, which is designed to increase hydraulic fracturing efficiency in plays where produced water disposal costs are high and where there are constraints on freshwater availability. The 350 extension targets applications in high-salinity water plays, such as the Marcellus and the Permian. Its development was driven by the need for improved proppant transport and for reduced completions costs by removing the need for extra...
