to a development program to be inaugurated in 194-6. Considerable work of a geological
nature was done in the re-examination of well formation samples to obtain all data
possible and several water wells throughout the Island were electric-logged.
Four more wells were rehabilitated during the year, leaving four wells in
this program still secured and requiring extensive re-work before they can be returned
to production. Four additional wells were standing and these require major repair and
work-over jobs before they can be returned to production. One such Job was in progress
at the end of the year. Observations of essential data necessary for scientific
reservoir control were increased consistent with the availability of personnel and
equipment.
Several minor repairs were made to cellar and surface well connections and
one major repair job started which will be carried on to conclusion. This repair job
was necessitated by corrosion of a liner. A second well was mudded off waiting major
repairs due to a leak in the casing probably resulting from corrosion. Observations
were being made at a third well to determine whether or not a suspected casing leak
exists. A fourth well requiring a major work-over job has remained mudded off
throughout the year awaiting sufficient drilling personnel to undertake the work.
As stated previously repair jobs due to corrosion can be expected to increase year
by year as the field grows older.
Tabulation No. 1 shows the status of all the oil and gas wells as of
December 31, 1945 and Tabulation No. 1-A shows the status of the Company water wells
as of the same date.
