SITE SUMMARIES (CONTINUED)

Site: BT4-1B

Priority:	Secondary
Position:	27.36771232°N, 94.35774732°W
Water depth (m):	1405
Target drilling depth (mbsf):	300
Approved maximum penetration (mbsf):	300
Survey coverage:	• Rudder 2-D dipline 3020 • Shotpoint 284.00 • Rudder 2-D crossline 3019
Objectives:	Hydrodynamic analysis of a passive margin. Brazos-Trinity Basin #4 sites are to serve as a reference location to establish basic rock and fluid properties over a range of effective stresses in a normally pressured section.
Drilling program:	APC to refusal with drillover and XCB
Wireline logging program:	Triple combo, FMS-sonic, VSP
MWD program:	GVR, ADN, APWD
Nature of rock anticipated:	Hemipelagic mudstone with some unconsolidated turbidite sand
