IP based CCTV in drilling
(2008) Artymiuk, Jan; Aashamar, Knut
The introduction of IP CCTV cameras has made it technically possible to have remote surveillance and control of drilling equipment. The live video transmission on Internet (or UMTS/GSM) enables integrated drilling operations from a drilling control room situated at the drilling company headquarter. Using Internet (or even UMTS/ GSM) this integrated operation drilling control room can give support to a number of drilling operations at different locations. As an example, the presentation will give a brief description of an integrated operation drilling control room giving support to a number of drilling rigs in the North Sea. The presentation will focus on the IP CCTV part, but will also cover the real time data and control transfer of data from the drilling rig to the integrated operation control room.

Bearing constructions applied for drilling boreholes with rigs are most commonly frame structures consisting of rigs or drilling masts. Their main bearing elements - shears - are deposited on foundation beams in the foundation plates in the ground or the subbase. In such a system the subbase is a basis for the rig and mast. The height of such a construction in the form of a cubicoid framework enables assemblying devices protecting the drilling well's outlet. In operating conditions, the structure undergoes numerous loads, frequently exceeding those in the rig and mast. Hence much attention is paid to the construction of subbases as it is a guarantee of safe operation of the rig.
Analiza konstrukcyjna stref zgrzania rur płuczkowych
(2008) Artymiuk, Jan; Bednarz, Stanisław; Kiełbik, Wiesław
During drilling operations in the well Odrowążek 1 in the north part of the Świętokrzyskie Mountains nine instances of string breaking took place. They were recurrent, similar in character and place of occurrence. The elements of the broken string were analyzed for their construction, non-invasive analyses, material tests and strength analysis. The results of the construction analysis are presented in the paper.

Some operations accompanying drilling procedure require performing activities on the mast or rig, high above the floor. Work safety reasons dictated working out bridges with mobile platform over the floor. Depending on the length of the casing pipes, location of mud head and Kelly, the height of the platform can be regulated. The design of the bridge, results of applicability and load test results were discussed in the paper. The positive results enabled introducing a given bridge type to exploitation.

Connection of mud swivel to drill string creates the transition zone from rigid mud swivel to thin tubular string rotating at considerable tension load. The sub under swivel stem requires particular care during exploitation and maintenance. Geometry of swivel sub and its thread connection to stem exerts influence on stress concentration at dynamic loads. This leads to material fatigue and microcrack creation risk and connection thread break off or fracture. Material researches carried out allow better assessment of pin crack process during normal work and freeing stuck drill string operation.
