    摘要： Gas monitoring apparatus associated with a remotely operated seabed system, the apparatus including a detector which is adapted so as to enable detection and/or measurement in real time the interception of shallow gas in a bore hole. In one form the gas monitoring apparatus is suitable for use with a drilling rig for drilling into a sea bed, the drilling rig including a drill string. The gas monitoring apparatus includes a housing with a collecting chamber therein for receiving drilling fluid returns which result from a drilling operation. The apparatus further includes a discharge conduit for discharging the drilling fluid returns from the collecting chamber, the collecting chamber and discharge conduit being configured so that the drilling fluid is discharged in a stratified flow which includes a predominantly dissolved gas containing phase, and if present a free gaseous phase. A gas sensor is associated with the discharge conduit and positioned so as to sense any gas in the predominantly dissolved gas containing phase and transmit the measured gas concentration signal in real-time to a surface operating station. In another form the apparatus includes a gas monitoring probe assembly suitable for use with a drilling rig for drilling into a sea bed, the gas monitoring probe assembly including a housing attachable to one end of a drill string of the rig and which includes a gas sensor having a gas sensor face within the housing.

    摘要： An apparatus and system for accessing a flow system (such as a subsea tree) in a subsea 3 oil and gas production system, and method of use. The apparatus comprises a body 4 defining a conduit therethrough and a first connector for connecting the body to the flow system. A second connector is configured for connecting the body to an intervention 6 apparatus, such as an injection orsampling equipment. In use, the conduit provides an 7 intervention path from the intervention apparatus to the flow system. Aspects of the 8 invention relate to combined injection and sampling units, and have particular application 9 to well scale squeeze operations.
