In its efforts to provide automated meter-reading services to the utility industry, Schlumberger faces the problem of deploying receivers efficiently. In a geographic region, the problem is to install the minimum number of receivers on existing utility poles so that all wireless meters in that region can transmit their readings to at least one. Schlumberger first encountered this large-scale pr...

We want to create interactive surface design systems which provide intuitive interfaces to parametric surface representations. In this paper, we show how the technique of Differential Manipulation can be used in constructing such interfaces. It allows surface manipulation issues to be treated separately from surface representation issues. Arbitrary differentiable functions of representation par...

Schlumberger RPS successfully applies software measurement to support their software development projects. It is proposed that the success of their measurement practices is mainly based on the organization of the interpretation process. This interpretation of the measurement data by the project team members is performed in so-called ‘feedback sessions’. Many researchers identify the feedback pr...

To sustain its competitive position as the leader in providing information solutions to the oil and gas industry, Schlumberger transitioned to a cutting-edge product-platform software architecture by embedding a leading geological modeling software product—Petrel—within Ocean, its collaborative open software platform. The purpose was to open up Petrel through the layered Ocean platform to broad...

We present a general formulation for solving frequency or time domain electromagnetic data using an all-at-once approach. In this ∗Currently at EMI Schlumberger, Richmond, California, USA 94804.

A novel VSP imaging method that only requires a local velocity model around the well is presented. This method is denoted as a ‘local migration’, where the modelbased forward propagation and backward propagation operators are computed using a local velocity model between the well and the the target body. The velocity model for the complex overburden and salt body are not needed, and the source-...

<p class="TesisTextOneHalfSpace"><em>Indonesia is one of the country having a lot geothermal fields potentially used as source energy. For example, Java island noted to have almost 57 fields. One those which rarely studied Guci field. Hence, there was conducted research investigate subsurface image and system in field based on resistivity data. </em><em>The carried out u...

In 1947, Stanolind Oil & Gas performed the first experimental hydraulic fracturing treatment in the Hugoton field in southwestern Kansas, USA. Since then, E&P companies have employed this reservoir stimulation technique extensively to enhance or prolong well productivity. Indeed...
