REPORT OF THE COMMISSION

 

This cause came on for hearing before the Commission on October 25, 1956, at 10:00 a.m., in Room 243, State Capitol, Denver, Colorado, after publication of Notice of Hearing as required by law, on the Commission's own motion to consider measures to prevent the waste of oil and gas in the "J" sand of the Beall Creek Field in Logan County, Colorado; and to consider an order limiting the production of oil or gas, or both, from the said "J" sand pool, and to limit and allocate the production from such pool among or between tracts of land of separate ownership therein on a fair and equitable basis.

 

At the hearing, considerable disagreement arose among the various operators as to the accuracy of the results of the bottom hole pressure survey.  Furthermore, the gas-oil-ratio tests may be subject to question.  The Commission considered the figures submitted in an effort to properly evaluate the condition of the field in relation to correlative rights and the possibility of the existence of wasteful production practices; however, after careful consideration, the Commission has come to the conclusion that the figures submitted by the operators may, in part, be somewhat inaccurate, so that it would be inadvisable to base a decision in regard to this field on the statistics presently available.  It is the Commission's belief that an accurate bottom hole pressure survey and up-to-date gas-oil-ratio tests should be conducted in the field under the Commission's supervision so that the Commission will be better enabled to analyze the field conditions and so arrive at a proper order for this field.

 

FINDINGS

 

The Commission finds as follows:

 

1.      That due notice of the time, place and purpose of the hearing has been given in all respects as required by law.

 

2.      That the Commission has jurisdiction over the subject matter embraced in said Notice, and of the parties interested therein, and jurisdiction to promulgate the hereinafter prescribed order.

 

3.      That the operators should conduct a current gas-oil-ratio survey of all wells producing from the "J" sand reservoir of the Beall Creek Field.

 

4.      That the field-wide bottom hole pressure survey of the "J" sand reservoir of the Beall Creek Field which was taken on the 18th day of October, 1956, was performed under conditions which may have tended to give inaccurate results, and that another survey is necessary before the Commission takes action in this matter.


 

ORDER

 

NOW, THEREFORE, IT IS ORDERED, that the operators and owners of wells producing from the "J" sand reservoir of the Beall Creek Field, Logan County, Colorado, shall make a gas-oil-ratio test of each of his producing wells; that each such test shall be taken on either the 28th, 29th or 30th day of November, 1956, and that subject well shall be produced at a stabilized rate for a period of forty-eight (48) consecutive hours; that the gas-oil ratio shall be computed on the basis of the measurement of oil and gas during the last twenty-four (24) hours of said period; that special care shall be taken to obtain an accurate measurement of the volume of water produced during the testing period; that the volume of gas measured shall be computed in units of cubic feet at a base pressure of 15.025 psia and a base temperature of 60° Fahrenheit; and that this gas-oil-ratio survey shall be supervised by a Commission engineer.

 

IT IS FURTHER ORDERED, that all wells producing from the "J" sand reservoir of the Beall Creek Field shall be shut in at 9 a.m., December 3, 1956, and shall remain shut in until all wells completed in the "J" sand formation have been tested at a sub sea [sic] datum of minus Seven Hundred Fifty (750) feet.  A twenty-four (24) hour shut in pressure shall be determined on all wells by means of an Amerada, Humble or other approved type of bottom hole pressure recorder, in accordance with good engineering practices.  The Commission recognizes that it may be necessary to kill various wells in order to obtain a bottom hole pressure in the manner prescribed herein; therefore, the twenty-four (24) hour shut in period shall commence at the time all wells have recovered a volume of fluid equal to the fluid which may have been used to kill, the well.   A Commission engineer will be in the field to supervise the bottom hole pressure survey and is authorized to revise any portion of this survey in case of unforeseen difficulties.

 

IT IS FURTHER ORDERED. that the rules and regulations contained herein shall become effective herewith.

 

ORDERED this 23rd day of November, 1956.
