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.

Drilling contractors urged to participate in API standards development

img-featured-generic-workersTN_default

IADC and API are both urging more participation from drilling contractors in API workgroups in the coming year. Work is ongoing for as many as 27 drilling-related standards this year, according to Roland Goodman, Manager of Upstream Standards at API. Of particular note are efforts to revise API Standard 53 and API Recommended Practice 54, which could each carry significant impacts on drilling operations. “It’s important that we get the drilling contractors involved in everything that we do that is drilling-related because they are the ones that are implementing many of these things,” Mr Goodman said.

Industry may see more flexibility under Trump administration, but focus on operational risk unlikely to change

Michael D. Farber, Partner at Van Ness Feldman, said a new administration is not expected to bring drastic changes to BSEE’s focus on operational risk.  Mr Farber provided a regulatory forecast at the IADC Houston office on 19 January.

The oil and gas industry may be looking for changes to be made under the Trump administration, such as reversing the withdrawal of Arctic and Atlantic acreage from leasing and denial of Atlantic seismic geophysical and geological permits. However, when it comes to the Bureau of Safety and Environment Enforcement (BSEE), there will likely be policy continuity in the agency’s focus on operational risks, according to Michael D. Farber, Partner at the law firm Van Ness Feldman, and R. Scott Nuzum, Counsel at Van Ness Feldman. “When you think about the person who holds the job of BSEE director, each night before that person’s head hits the pillow...

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...

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...

Diamond Offshore training translates human factors to rig floor operations

Diamond Offshore’s Ocean Technology Center opened its doors in 2013. It is a simulation and training hub that houses drilling, crane and stability simulation packages.

“MUD WEIGHT GOING IN 14.3 WITH A 75 VIS!” screams the derrickhand from the intercom system. The driller and assistant driller look up from their trend screens at the pipe turning in the rotary. They have been drilling ahead for a couple of hours, and the conversation drifts from work to vacation plans for the next time they are home. They are interrupted as their floorhand – who has been difficult to deal with lately – bursts into the drill shack demanding to talk to them about why he didn’t get recommended for a promotion.
