Gastar Exploration Provides Update on Mid-Con 7H Well and Activity in Hunton Limestone Oil Play

HOUSTON, Dec. 17, 2013 /PRNewswire/ -- Gastar Exploration, Inc. ("Gastar") (NYSE MKT: GST) today announced that the Mid-Con 7H well in its Hunton Limestone oil play in Oklahoma reached a peak 24-hour gross initial production ("IP") rate of 906 barrels of oil equivalent ("BOE") per day and subsequently averaged 782 BOE per day (60% crude oil) over the following 17 days.  The Mid-Con 7H well is flowing these rates naturally through 4.5-inch production casing as compared to the previously announced wells which were flowing through production tubing with the assistance of gas-lift.  The well was completed in the Hunton Limestone formation utilizing a 19-stage fracture stimulation over the well's lateral length of 4,250 feet. Gastar has a 48% working interest ("WI") (38% net revenue interest "NRI") in this non-operated horizontal well drilled within an area of mutual interest ("AMI") in Kingfisher County, Oklahoma.

J. Russell Porter, Gastar's President and CEO, commented "The previously announced Hunton Limestone wells are typically flowed through 4.5-inch casing for several days after which they cease flowing and gas-lift is installed.  The Mid-Con 7H well has continued to flow up the production casing and has yet to cease production so it can be placed on gas-lift.  With the Mid-Con 7H results, four of our last six non-operated wells are producing, or capable of producing, at initial production rates significantly above our internally generated type curve of 608 BOE per day (65% crude oil) and estimated ultimate per well recovery of 436,000 BOE. At an estimated drilling and completion cost of $5.0 million, the Mid-Con 7H well should generate a substantial internal rate of return at current NYMEX forward strip pricing."

The previously announced Mid-Con 6H well (GST 50% WI; 39% NRI) continues to produce at strong rates. In the 26 days since the peak IP rate, the Mid-Con 6H has averaged a gross production rate of 1,300 BOE per day (78% crude oil) compared to the previously announced gross IP rate of 1,442 BOE per day and 10 day average of 1,133 BOE per day (86% crude oil). 

Gastar's first operated well in our Hunton Limestone oil play, the Burton 16-1H (GST 79% WI; 66% NRI), is currently in the early stages of flow-back operations.  Gastar's second operated well, the Townsend 6-1H (GST 100% WI; 80% NRI) is currently being fracture stimulated and is expected to begin flow-back operations in early January 2014.  Drilling operations began on Gastar's third operated well on December 11, 2013, the Taborek 22-1H (GST WI and NRI to be determined pending outcome of forced pooling hearings), with flow back operations expected to commence in the first quarter of 2014.

Gastar's operating partner in the AMI, Husky Ventures, is currently drilling two Hunton wells (Mid-Con 9H and Mid-Con 10H) with one additional Hunton well (Mid-Con 8H) waiting on completion.  Gastar is participating in all of these additional AMI wells.

DevOps has often been described in terms of CAMS: Culture, Automation, Measuring, Sharing. While we’ve seen a lot of focus on the “A” and even on the “M”, there are very few examples of why the “C" is equally important in the DevOps equation. In her session at @DevOps Summit, Lori MacVittie, of F5 Networks, will explore HTTP/1 and HTTP/2 along with Microservices to illustrate why a collaborative culture between Dev, Ops, and the Network is critical to ensuring success.

Then he will explore the relationship between IoT and Big Data. Specifically, he will drill down to how the 4Vs aspects intersect with IoT: Volume, Variety, Velocity and Value. In turn, Tony will analyze how the key components of IoT ...

DevOps delivers remarkable results. But does it help all of IT? Can traditional ‘mode 1’ IT benefit as much as innovative ‘mode 2’? How about the rest of your business? Or have you just shifted your bottleneck? And if so, what can you do about it? Improving dev and ops is necessary, but not sufficient. It often just shifts the burden sideways (e.g., to PMs, SQA, InfoSec, DBAs, NOC, etc.), upstream (to the PMO, Controller, Business Liaison, etc.), or downstream (to TechPubs, Service Desk, Traini...

Mobile messaging has been a popular communication channel for more than 20 years.

Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text...

You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud.
