Abstract: An accelerometer (305) for measuring seismic data. The accelerometer (305) includes an integrated vent hole for use during a vacuum sealing process and a balanced metal pattern for reducing cap wafer bowing. The accelerometer (305) also includes a top cap press frame recess (405) and a bottom cap press frame recess (420) for isolating bonding pressures to specified regions of the accelerometer (305). The accelerometer (305) is vacuum-sealed and includes a balanced metal pattern (730) to prevent degradation of the performance of the accelerometer (305). A dicing process is performed on the accelerometer (305) to isolate the electrical leads of the accelerometer (305). The accelerometer (305) further includes overshock protection bumpers (720) and patterned metal electrodes to reduce stiction during the operation of the accelerometer (305).

Abstract: A method of computing the location of air guns and hydrophones within a seismic spread utilizes a navigation network having a plurality of stations. The network provides a plurality of navigation observations. A number of the observations consist of magnetic bearings which are used to derive the hydrophone locations. The method includes the steps of: a) obtaining a set of observations from the network, each observation being obtained by using navigation devices whose origin system moves independent of the navigation reference point; and b) forming a design matrix wherein the magnetic bearings are modeled based on the equation (I). (see formula I)

Abstract: An apparatus and method are provided for ensuring good coupling and vertically planting (12) of seis-mic receivers while substantially reducing the need for interconnecting wires and costly surveys. The appara-tus includes an acquisition unit (AU) (20) for measuring seismic energy and a planting member (12) for engag-ing and planting the AU (20). An electronic surveying instrument (14) is coupled to the planting member (12) for determining the location of the AU (20). An installer (16) plants the AU (20) in the terrain (22) in near vertical alignment using the planting member (12). Once the AU (20) is planted in near vertical alignment, coordinates are downloaded from the electronic survey unit to locate the planted AU (20).

Abstract: A seismic ocean bottom posi-tioning device includes a series of seismic stations (14) spaced apart at a predetermined interval along a ca-ble. Each station (14) includes a hydrophone, a motion sensing device such as a geophone (22) and an acous-tic positioning circuit (24). A pream-plifier is coupled to a seismic channel. The hydrophone (20) is also coupled to the seismic channel. An acoustic chan-nel is also coupled to the preamplifier and coupled to the hydrophone .

Abstract: A static seal assembly (10) comprises an underwater cable (12) having: (a) an outer jacket (14); (b) a metal housing (16) provided with annular grooves (26) containing O-rings (28) or similar seal members, encompassed by a rigid shell (30); and overmoulded by (c) a cover (34), which also has an integral shoulder (38) formed during moulding to fill an annular groove (36) provided in the metal housing (16) for that purpose. The rigid shell (30) is formed of glass-filled polyurethane having a flexural modulus of about 650,000 psi, a surface hardness of about 80 D, and a thickness of 0.15-0.20 inches. The material is self-bonding with the overmoulded cover (34), which is also composed of polyurethane, as is the outer jacket (14). Alternatively, the rigid shell (30), overmoulded cover (34), and cable jacket (14) are all formed of polyethylene or nylon.
