1、 JOINT ASSOCIATION SURVEY ON 2015 DRILLING COSTS Sponsored by AMERICAN PETROLEUM INSTITUTE INDEPENDENT PETROLEUM ASSOCIATION OF AMERICA MID-CONTINENT OIL please feel free to contact Alexa Carlson in APIs Statistics Department at CarlsonAapi.org. Washington, D.C. March 2017 UNDERSTANDING THE JAS DATA
2、 On a regular basis, the API receives well drilling and completion data from the IHS Energy Group, which is added to the well drilling database, the Dynamic Well Data System (DWDS). The DWDS, insofar as possible, contains reasonable and reliable data and is, to our knowledge, the most comprehensive
3、and detailed source for domestic oil and gas drilling activity available. This database is a crucial tool that has been used by the API Statistics Department for over sixty years to produce the publication, the Joint Association Survey on Drilling Costs (JAS).This report is the leader in delivering
4、drilling and completion expenditures data to the oil and gas markets. To improve reader comprehension of the JAS data, it is important to point out that the JAS contains most, but not all, of the wells completed in the U.S. during the survey year. This is due to the often significant time lag from m
5、onths to years between when a well is completed and when it is reported to API and added to the DWDS. Because of this delay, a fraction of the wells completed during a survey year are inevitably reported to us after the JAS is published. In order to capture this fraction of as-of-yet unreported well
6、s completed in the survey year, API publishes estimates of wells completed and corresponding footage drilled four times a year in the Quarterly Well Completion Report (QWCR). According to the most recent QWCR, Fourth Quarter 2016, the estimated number of wells drilled in 2015 is 28,809. The reported
7、 number of wells contained in the 2015 JAS is 27,026, a difference of 1,783 wells. Thus, to provide data users with the most accurate measure of 2015s complete drilling activity, the 1,783 estimated wells, along with their footage 7.97 million feet and expenditures $7.6 billion are incorporated into
8、 the Executive Summary and its two corresponding tables. The rest of the JAS publication refers solely to the 25,279 Total U.S. Wells, omitting sidetrack wells and Quarterly Well Completion Report estimates. This use of both data sets provides a full description of the industrys drilling operations
9、in a given year. Additionally, it is important to note that while the costs reported to API reflect the drilling and completion costs for each well, the wells included in the report are only ones that have been completed to the Christmas tree stage in the current survey year. This classification ens
10、ures that each well is only included in one JAS report, even if the well is drilled over a period spanning multiple years. EXECUTIVE SUMMARY Drilling expenditures decreased significantly as the oil and gas industry spent less annually drilling and equipping wells in the U.S. in 2015 than it did in 2
11、014. According to the 2015 Joint Association Survey on Drilling Costs (JAS), the industry spent 27.2 percent less in 2015 to drill and equip wells in the U.S. than it did in 2014. Total drilling expenditures were estimated to be $122.8 billion in 2015, compared to $168.7 billion during the previous
12、year. In addition, the number of wells decreased considerably by 37.6 percent, while total footage decreased by 29.5 percent. Despite the decline in the number of wells and total footage, average depth per well increased 11.3 percent from 9,199 feet in 2014 to 10,235 feet in 2015. Expenditures decre
13、ased for all well types in 2015 relative to 2014 levels. Exploratory well expenditures in 2015 amounted to approximately $5.64 billion, a decrease of 6.6 percent from the previous years $6.04 billion. This includes a decrease in exploratory oil spending of 46.8 percent from $3.08 billion in 2014 to
14、an estimated $1.64 billion in 2015, while exploratory gas expenditures were estimated at $858 million in 2015, down 34.0 percent from $1.3 billion. Over the same period, development well expenditures were estimated to be $109.6 billion compared to 2014s $148.7 billion, which is a 26.3 percent decrea
15、se. Spending decreased 29.2 percent to $73.7 billion in 2015 for development oil wells, compared to $104.1 billion in 2014. Additionally, development gas spending was an estimated $27.7 billion in 2015, down 24.1 percent compared to $36.5 billion in 2014. The industry continued to spend more drillin
16、g for oil than for natural gas. In 2015, oil expenditures accounted for 65.4 percent of the total drilling expenditures down from last years 69.3 percent; gas expenditures accounted for 24.8 percent up from 2014s 24.4 percent; and dry hole expenditures reached 9.9 percent of total drilling expenditu
17、res up from the past years 6.3 percent. Total Wells, Footage Drilled in 2014, 10,625 shale wells were drilled, totaling an estimated 158.6 million feet and $70.1 billion in expenditures. The overall decrease in number of wells from 2014 to 2015 includes a decrease in shale-oil wells as well as a sli
18、ght increase in shale-gas wells. Table 1: 2011-2015 Trend of Estimated Shale-Oil & Shale-Gas Well Costs (Footage in feet.

45、 American Petroleum Institute 9 Coalbed-Methane Gas Drilling in 2015 Coalbed-methane is an energy resource with dwindling importance. The technology of drilling, completing, and stimulating coalbed-methane reservoirs has been underutilized in recent years. Typically coal gas reservoirs are shallow a
46、nd difficult to produce because they are often interbedded with numerous sand lenses and shales, and they require initial dewatering to reduce pressure before achieving production. This inefficiency has led to the decline in coalbed-methane gas well drilling and expenditures from 2011 to 2015. In 20
47、15, omitting QWCR estimates and sidetrack wells, 167 coalbed-methane gas wells were drilled compared to 352 in 2014, representing a 52.6 percent decrease. The level of spending to drill coalbed-methane gas wells in 2015 was estimated to be $70.2 million. The average estimated cost for each coalbed-m
48、ethane gas well in 2015 was $420,442 and the average estimated cost per foot was $199. The estimated average distance drilled was 2,112 feet.

49、t 2017 The American Petroleum Institute 10 Sidetrack Drilling in 2015 A sidetrack well is a new section of well, drilled from an existing well bore to a new objective hole location, and its cost is usually higher than non-sidetrack wells. This difference is due to differing cost structures that apply to sidetrack and non-sidetrack wells and is the basis for why sidetrack wells are excluded for a majority of this reports analysis. In 2015, operators spent $12.0 billion in the U.S. to drill and equip sidetrack wells. This was a 41.2 percent
