default-img-featured-land

Newfield Exploration Company‘s STACK (Oklahoma’s Sooner Trend oilfield, Anadarko Basin, and Canadian and Kingfisher counties) well recently achieved record oil production, according to the company’s recently disclosed results. Newfield has also raised expectations for its Q1 2017 domestic production. The Burgess well (4,859-ft lateral length), located in Kingfisher County, Okla., and the heart of the company’s 300,000 net STACK acres, achieved a 24-hr flow rate of 2,931 bbl of oil equivalent per day (BOEPD) (69% oil) and a 20-day average rate of 2,492 BOEPD (70% oil). When compared against publicly available industry data, the Burgess achieved record 24-hr oil production per 1,000 ft of gross perforated interval (1,000 ft GPI), or 417 bbl of oil per 1,000 ft GPI. The well also had a record 20-day ...

State bans, law suits could influence the future of hydraulic fracturing in the US

default-img-featured-land6

By Kelli Ainsworth, Editorial Coordinator Hydraulic fracturing, critical to the recovery of North American drilling activities, remains under threat in the US. Several states appear poised to ban hydraulic fracturing, including California and Maryland. Further, several legislation and legal actions are ongoing, including the US Bureau of Land Management (BLM) hydraulic fracturing rule that remains under appeal and a lawsuit in Oklahoma regarding fracturing and seismicity. At the same time, the general public remains very concerned about the effects of hydraulic fracturing – in terms of drinking water quality and induced seismicity, for example. Such concerns continue to drive the actions and decisions for many state agencies. “Perception affects what laws, regulations and bans go into place,” said Michael Gray, ...

Chevron tests, compares single-cluster and multiple-cluster completion methods in Antelope Shale wells

chevronlogo

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.

CT sleeves open in 2 DUC wells after 32 months downhole

screen-shot-2017-01-30-at-3-45-16-pm

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...
