Here's another Press release
Mr. Michael Kinley reports
Abstract Enterprises has received preliminary drilling results of well
ER-97, which spudded April 2 on the company's South Erin 1,350 acre
property in Trinidad. The company's on-site geological team has reported
reaching the planned depth of 6,000 feet and its interpretation of sonic
logging procedures.
The target formations of Lower Forest A, Lower Forest C and Upper Cruse
sands were confirmed, but were encountered approximately 350 feet higher
than planned in the hole at 4,000 feet subsea, 4,650 feet subsea in the
case of the Lower Forest A and Lower Forest C sands, respectively. The
Upper Cruse was encountered as planned at 5,950 feet. Sand thicknesses were
approximately 70 feet for both the Lower Forest sands as expected. While
the structural setting predicted in the company's geological report on the
property has been confirmed, the sands in these formations were wet. The
higher in-hole depth of the formations, together with certain missing or
faulted out sections in the well log reports, has caused the company to
conclude that the hole encountered a previously unknown normal sealing
fault and that drilling to date has occurred on the upthrown side of this
fault.
The company's consulting geologist, in consultation with its engineering
staff, has recommended that drilling be redirected, within the current
hole, due east of the existing location in order to explore the downthrown
side of the sealing fault in both the Lower Forest A and C sands where
hydrocarbons are now believed to occur. This theory is supported by the
existence of producing wells several hundred feet east of the original
drilling location F20; OC/4. The existing well bore has been cemented and
plugged up to 1,565 feet, at which depth drilling is now being redirected
to reach the target sands approximately 200 to 300 feet due east on the
downthrown aide of the fault, and 200 feet lower in hole than observed on
the upthrown side.
The nature of this faulting mechanism and the probable occurrence of
hydrocarbons on the downthrown side of a fault are consistent with the
experience of the company's on-site geological and engineering staff, and
with the history of geology in Trinidad. Drilling is now expected to take
an additional seven days. |
