abyssal depths of the Gulf of Mexico and the Caribbean Sea. The plateau margin normally is at depth of 550-900 ft, but in places it is shallower; minimum depths of 240 ft are recorded on the western margin, southwest of the Triangulos reefs. Much of the northern part of the plateau has been the site of limestone deposition dating from Tertiary ...

Hard formation challenges drilling performance in Gulf of Mexico. PEMEX needed to improve ROP and bit durability while drilling an 8 1/2-in, 30° deviated interval through a Mid-Cretaceous hard limestone formation with traces of chert in the Gulf of Mexico. Unconfined compressive strength (UCS) in this area ranges from 18,000 to 25,000 psi.

Cement, mud, and drilling fluid is coming in globs down, Me and Hen look at each other, both thinking we are fucked. Dennis is yelling into the phone now. Unknown to me, the problem of shale or limestone doesn't matter. In the oilfield they have an invented term that is a 50% mix of limestone and shale called Marl or Calcareous Shale.

Mesozoic benthic foraminifers, recovered from five single-bit holes drilled in the southern Gulf of Mexico on Deep Sea Drilling Project Leg 77 are rare, poorly preserved, and scattered throughout the dominantly redeposited sediments. The Mesozoic sequence at basin Sites 535 and 540 consists largely of laminated limestone with smaller amounts of ...

SALT-DOME LOCATIONS IN THE GULF COASTAL PLAIN, SOUTH-CENTRAL UNITED STATES By Jeffery D. Beckman and Alex K. Williamson ABSTRACT Information on salt domes in the Gulf of Mexico Coastal Plain, south-central United States and the adjacent Continental Shelf were compiled from major published sources, 1973-84.

However for the vertical column bitumen, increasing mud weight may not be efficient, and sidetracking to avoid further encounter may be more practical. These findings are consistent with the drilling experience in the field, and may help to develop a strategy to manage future bitumen encounters in deepwater Gulf of Mexico.

Review a map of oil drilling in the Gulf of Mexico. Display the map Gulf of Mexico: A Geography of Offshore Oil from the October 2010 issue of National Geographic magazine. Explain to students that the United States has been pumping oil out of the Gulf of Mexico since 1938. Most of the near-shore wells are depleted, which has led to drilling at ...

Recent offshore exploratory success has focused industry interest on porous Lower Cretaceous carbonates of the James Limestone in the eastern Gulf of Mexico. The current offshore play targets the interior James platform trend in the Viosca Knoll and Mobile areas, south of Mississippi and Alabama, where water depths are 30-60 m (98-197 ft ...

The Drill Site where Myrtle is Located in the Gulf of Mexico. Using a tungsten–carbide roller cutter, researchers will begin by drilling to 500m meters, cutting through the sediment to the limestone. At 500 meters, the hole will be cased in steel and drillers will switch to a diamond-tipped bit that can be used to retrieve 3-meter long cores.

The Gulf of Mexico basin is a contradiction: a highly mature petroleum province that continues to yield new frontier plays. Over much of the basin, drilling has penetrated only the upper one-half to two-thirds of the sediment column. Exploration of complex structures beneath canopies is in its infancy.
